I have an 05 rx8. your 2nd gear pull starting at 19mph is kinda slow... I mean, it shoulda picked up once it hit 4k-4.5k. maybe i gotta go redline mine some more for comparison. hahaha
@LightningMAS Tell that to the fully built rx8 with a 20b and a GT47R turbo under the hood, guarntee whatever you have that car will eat it. Lol.. You can call a car slow all you want, but you know what. theres ALWAYS gonna be someone quicker then you. So i wouldn't be bashing the car till you know how it can be built. Oh and FYI, Wankel engines are some of the fastest engines in the world. Don't believe me? look it up.
@LightningMAS Yeah I'm serious. You don't have to use cute internet lingo to try to sound awesome. The 2JZGTE only sounds good half the time because people put full exhaust systems and headers on it to amplify the sound. Sound is a preference as well, so just because it's not my favorite doesn't mean i'm dumb. But of course you think that opinions are fact apparently.
I can find many engines that sound better, like Nissan's VQ35/37DE series or RB26DETT. I do like the 2JZ, just not my favorite
@LightningMAS I'd have to say although I'm definitely a fan of turbo fours, 6 cylinder engines are by far my favorite. Of course V8s are great but 6 cylinders are just plain awesome, whether they're inline, flat, or v configurations. Personally I've been interested in Hyundai, and I can't wait to see their next Lamba V6 in the Genesis Coupe with 333hp... without FI. They're really stepping up and becoming what Japanese automakers were in the early 90's.

for all you people who say its bad for the car and that mazda put the redline at 8500 for a reason etc etc... you actually should listen to these people saying you should redline it from time to time, these engines were designed different, i use to work for mazda when these first came out here, and we were instructed to tell our buyers about the cars, how to maintain them, about cold operation (so you dont flood it), and about redline which factory fuel cutoff is actually 9500
@rcrocker02 as well as to redline it from time to time cause it gums up the engine over time if you baby them to much, they were DESIGNED to rev like crazy and they would actually rev higher if the accessories and transmission could handle it, but without upgrades anything over 10,000 rpm would destroy other components but not the engine itself. before trying to argue with me go do some research and keep in mind youll be arguing with a past mazda employee who was dealer-educated about these cars
above 9000 rpm is actually doing harm to the engine.
It means that the rotors make 3000 rpm and at that point the apex seals start to fly or take off just after the 2 humps in the rotor housing wearing out your rotor housing quickly.
@whiterider360 the renni can handle over 13k bro, read up about it, revs are good in the rotarys, i mean hell u have to rev the thing before u turn it off.
lol what a dumb ass. Healthy to redline it??? Thats beyond redline first of all. And i think the auto manufacture new what they was doing when they designed the motor an put the red line at 8500 rpm. Its a red line for a reason. That means you go any further an your going to blow your shit dumb ass. You'll find out eventually and you'll be saying" damn why did i listen to those idiots" lol
@hotboyonfiyer just because you opened your dumbass mouth.. you obviously dont know what this video is for, the flash raised the factory redline to 9500 because of the increased power, that RB company has been working closely with mazda's rotarys for decades so they know what they're doing

Cause you got idiots that think like you.If they wanted you to shift at 10Krpms they would have put the redline there genius

No sure how these rotarys work, but I once had a BMW325 and basically had a chip which higherd the redline. However, if you push it too far, you get this problem called "Valve Bounce" I blew the engine up in the end LOL (not funny at the time)
@richythepianoman Valve bounce? Rotarys have no intake or exhaust valves, At least the ones I have seen. Intake and Exhaust ports are merely holes allow air to be pushed in and out when the rotar passes.
@DIENAMICProductions none at all, the rotary motor could easily hit 13k if it wanted to its only limited by the transmission being weak, its healthy for the motor to be taken to the high rpm's clears carbon which is very harmful for these engines.
@kakashithemimicninja If you knew anything about the Renesis engine, you'd know that redlining like that is actually healthy for the engine. He obvious doesn't drive like that normally, but redlining once a day or so is actually recommended by RX-8 enthusiasts as it helps prevent carbon buildup.
@Septher exactly. redlining IS healthy for the engine. this particular engine, also, before you turn your car off, its good to rev it in order to clear up some carbon buildup as well. so you can have a healthy start next time you turn it on.
@Septher is the renesis engine the same thing as a rotary engine? cuz im pretty sure that's the reason Rx-8s redline so high, instead of like 6500 or so..
Better than the people who dont redline their rotaries. Mazdas tested the renesis to much higher rpm than that. Willing to bet his engine lasts longer.
Keep that thing revved up. Redline it at least once a day to keep all the carbon out of the chambers. That is why so many automatic rotary cars have problems, they don't get revved up enough.
the 13b cant go above 13k cause of the harmonics of the engine will shake it apart. thats from mazda. so they had to have tested somewhere in that margin so you could very much be right.
I never said it was warrantied dumbshit, i said the engine can go up to 14,000 and Mazda have tested it up there. It stops making power after the redline, which is why the redline is there. If it made more power all the way up to 14,000 then Mazda would have designed Apex seals to take the abuse and the redline will be 14,000. It does not make power past redline, thats why redline is there, but it can and has gone to 14K
very true and the fact that the oil pump cannot supply good efficient flow of oil to lube the engine as it needs to be. It would require higher capacity pump, and more cooling of the oil as well as a more efficient filter. as you said, power drops off around 8500-9000 so no sense in going further without a good tune and that is why RB raised the rpms to take advantage of this. mazda did what they did to make it more durable for the ave driver.
well i fukd it big time pl8s a housing and a rota sold my m8 the rest coz he need afew things so im ending up buying another engine and guna port and build it myself i get seals and shit 4 $1000ish thn engine hopeful fine 1 around $2500-$3500
I took off from 19mph in second gear. That is why it takes so long. You never see 1st gear. Also keep in mind I am holding the camera in my left hand stearing with my clutch leg and shifting with my right arm. Meaning I have to take my knee off the wheel to shift. If I shift too hard the car pulls to the side. Not a very good thing when no one is holding the wheel @70mph (2nd) and 96mph(3rd)
@1994supra he started from <3k RPM, which means he didnt have all ports open. If you have any concept of renesis, you would know that renesis doesn't go full throttle till you hit 5.5k+ on RPM, not matter how much you step on it. I love how these supra mechanics try to comment on shit they don't know anything about
then u dont know absolutley anything about rotary engines...as long as he does do it all the time he can do it...actually with rotary engines it helps get rid of carbon build up...he can do it just he cant do it alot...remember its a renesis, they are made to be rev'd=why i love rotaries and why i own a 2nd gen RX7.
why can't you put a turbo on an rx 8? the rx 8 is one of my fav cars right now and i really want to get one when i get the money...(i have a 2005 mazda 6 right now) it's pretty sweet but it's no rx 8 :)
Rotarys can take redline for much longer than normal engines, so really he is just helping the engine. As long as he doesnt all ways drive like that "/
its a wankel rotary. its one of the longest lasting engines ever so long as you keep fresh oil in it and dont turbo it. rotary + turbo = ticking time bomb.
I'm running low 14's on a good day stock. Yes an RX7 is faster, but it needs a turbo and about 15K more to its price tag to do it. Let's also not get in to the fact you will be rebuilding your rx7 motor all the time or dropping another 10k or so to put a LS motor in it. So you can actually drive it, w/o the worrie of it breaking.
What? Not hating on the 8 but you need to get your facts straight. A stock FD runs 14's, and a lightly modified TII can run 14's as well. Not to take away from the 8 though considering that it N/A but don't hate.
If your referring to a CVT Automatic that would be true, however traditional automatics do have set gear ratios. The torque converter allows slippage which might give you the impression that it changes.
Just curious. Exactly how does some computer chip simply lift the redline? I mean redline isn't dependent on the car's ECU, isn't it more dependent on its engine, internals, etc. You can't just lift it with a chip without hurting it no?
the reason the rx8 engines redlines at 9200 is because it stops making power at around 8600 and there is no need to keep reving....the rx8 engine has been tested to function safely up to 14,000 rpms.....so with mods you make power beyond 8600 so you need higher redline to use the power....
ermm..but redline isn't really set just by "when the car stops making power", redline is the RPM range where just any higher would harm the engine. That's why they prevent you from going above a certain RPM. Mods just make more power on the path UP to redline, I still don't see why it would raise it..
Maybe you should have read his post. Engine can keep going to 14,000 RPM, but wont make much power after 8,600. With aftermarket upgrades such as turbos, power is made well after 8600 and so this is no problem for the car.
With that said, generally any car can reach above 9000 RPM with proper balancing but then you also have to take into consideration things like flywheels shattering and the like.
What? Not generally "Any Car" can touch 9000 rpm let alone ABOVE 9000rpm. Proper balancing? Try, new cams, stronger valves, forged pistons, new connecting linkages...
You would need a lot to get an internal combustion engine to reach 9000 rpm. Every moving part poses a possibility of something breaking. Average engine redline is gonna be somewhere near 6000. Giving it a 1/2 increase is NOT easy.
Then whats the point of comparing them? This engine, STOCK, will go to 14K RPM.
Thats like talking about planes and saying yeah, ANY transport vessel can reach 9000 ft cruising altitude, it just takes jets and wings but i never said it was easy.
i dont know about 14k rpm's. that requries lighter rotors, larger porting, better intake and exhaust, and a newly tuned ecu. not even drag rotaries get that high.
haha... no... Mazda themselves have tested a completely stock RX8 engine up to 14k.
The reason drag rotaries and street rotaries dont go that high is they stop producing power at about 7000rpm. Piston engines need lighter pistons, stronger rods, all sorts of stuff for such high RPMs. Rotaries are not so because they have so fewer moving parts they can safely reach higher RPMs on weaker components. Get your facts straight bucko.
truenofan is right, lighter rotors, stronger stationary gears, peripheral port and standalone ecu, also possible a de-rated water and oil pump to prevent cavitation. drag rotaries are usually turbo no need to go higher than 7k for turbo, more boost works just as well and as for a setup for 14k for the street at idle it would suck balls.
Im sorry but where is your source? What your saying, ISNT true, and no need to go higher than 7k for a turbo? WHAT? The MORE the RPMs, the more the turbo will CONTINUE making additional power. With a turbo it makes sense to push it to 14k but N/A as they are sold, mazda limits them to the 9k or whatever it is because they make less power. You are wrong about this and nothing yuo say makes sense. An engine capable of 14K revs can idle just as smooth as any other engine. God damn...
a turbo will not necessarily simply continue making power with rpm. ignition advance has to be set sooner the higher the rpm. with turbos you cant set them as soon as n/a cars because you will get detonation and destruction of motor. if it makes sense why isnt anyone doing it with mid to high boost?
why do some engines make most power at 9k but some race motors at 14k? all because the size of the port needs to be bigger for higher rpm. renesis ports are too small or 14k.
Yes, a turbo will continue making power at RPM because the exhaust gasses only increase in speed and pressure as RPM increases. I never mentioned anything about setting ignition before, and that is something that is EASILY doable and not a restrictor of RPM or turbo. People ARE doing it, thats the thing. You just may not realise it. And some engines make most power at 9k and some at 14k because they are different motors, different cams, and different timing profiles. It is NOT
NOT entirely because of port size like you act like it is. Renesis ports are big enough to go UP TO 14k, but the ports are so small they stop efficently making power (stop mixing A/F ratio properly enough) above 9k or so. THEY STOP MAKING POWER ABOVE 9K BUT THEY CAN EASILY REV TO 14K. The transmission is also another huge limiting factor, in that if they COULD make power above 9k the tranny couldnt handle it. The last limting factor is the eccentric shaft, easily upgradeable though.
he wasnt saying the engine is or isnt capable of revs. Nor was he saying how smooth it would idle. The point was that an engine that revs to 14k certainly has a HP peak in the later rpms and therefore would have no balls at low rpm (sitting at a red). Low end power best suits city driving because of all the stop and go.
Actually he said a rotary would require a lot of aftermarket components like new internals to reach 14K rpms. So yes, he was saying it wasnt capable of 14K rpms. He also mentioned that a engine capable of reaching 14K rpms wont idle smoothly.
Your post says an engine that revs to 14K has no balls low end. This isnt neccesarily true, its entirely dependent on the engine. Rotaries dont make a lot of torque low end because they have less combustions and combustion chambers than similar ICE.
"as for a setup for 14k for the street at idle it would suck balls. " is what he said which isnt indicating how smooth it would idle. I believe he was saying what i did about the low hp at low rev. and no high rpm engines wouldnt "necessarily" have low hp at low rev, but they dont. Any 14k rpm motor that outputs max hp at lower rpm would disintigrate at 14k rpm.The cam designed for low rpm hp wouldnt handle the high revs.
Saying something sucks at idle means "when it isnt moving" because thats what idle is. Saying it sucks at idle is NOT saying it has no low end toruqe.
I never said an engine will be able to have low end HP and no top end HP. You can have more low end torque than high end (and almost always do). An engine CAN have low AND top end power. Thats what I said, and that is true. I didnt say an engine would make 500 hp at 700rpm then 100 hp at 70000 rpm. Because no, that isnt possible.
Yah, Formula Mazda's use the Renesis, they rev to around 10,000 and put out about 280hp. The determining factor on the RX8 isn't that the engine can't rev that high, its that they couldn't build a transmission that'd meet those demands, and last long enough to be used on a street car.
Street RX-8s also use the Renesis; but the racing version is a 3 rotor not a 2 rotor that is the key difference. The 3-rotor race version also made around 400hp; not 280.
And actually transmissions have trouble dealing with power not necessarily just a high RPM band. Formula 1 transmissions last for awhile; a lot longer than the engines.
the 3 rotor is out of the mazda eunos cosmo, made between 1990 - 1995 and revd's upto around 6k, mind you it was no slouch at 300hp and 300ft/lb with 10PSI
rotaries the more rotors you have the lower the RPM you need to make and sustain power.
ok........i have an 05 rx8 and just bought it a month ago and now i have exhaust, pulley and intake and i can rev it close to 10k rpms. and i hit 97mph in 3rd. what else will the RB flash do for you?
that guys an idiot.. your 8 rocks.. the exhaust sound almost as good as mine.. is a midpipe in your future? it would make a world of diff and it would probaly help your flash a bit more.. cjwaggs from rx8club

THEREALSIDGUY 1 year ago
@Septher is the renesis engine the same thing as a rotary engine? cuz im pretty sure that's the reason Rx-8s redline so high, instead of like 6500 or so..

Better than the people who dont redline their rotaries. Mazdas tested the renesis to much higher rpm than that. Willing to bet his engine lasts longer.

Keep that thing revved up. Redline it at least once a day to keep all the carbon out of the chambers. That is why so many automatic rotary cars have problems, they don't get revved up enough.

the 13b cant go above 13k cause of the harmonics of the engine will shake it apart. thats from mazda. so they had to have tested somewhere in that margin so you could very much be right.

yup, it can rev over 13K but if its kept at 13K for long it shakes it apart, Mazda race rotaries iirc run to about 10-12K.

whitemagicwizard 1 year ago
I never said it was warrantied dumbshit, i said the engine can go up to 14,000 and Mazda have tested it up there. It stops making power after the redline, which is why the redline is there. If it made more power all the way up to 14,000 then Mazda would have designed Apex seals to take the abuse and the redline will be 14,000. It does not make power past redline, thats why redline is there, but it can and has gone to 14K
blackXSpr 2 years ago
very true and the fact that the oil pump cannot supply good efficient flow of oil to lube the engine as it needs to be. It would require higher capacity pump, and more cooling of the oil as well as a more efficient filter. as you said, power drops off around 8500-9000 so no sense in going further without a good tune and that is why RB raised the rpms to take advantage of this. mazda did what they did to make it more durable for the ave driver.

I took off from 19mph in second gear. That is why it takes so long. You never see 1st gear. Also keep in mind I am holding the camera in my left hand stearing with my clutch leg and shifting with my right arm. Meaning I have to take my knee off the wheel to shift. If I shift too hard the car pulls to the side. Not a very good thing when no one is holding the wheel @70mph (2nd) and 96mph(3rd)
aaronwlkr 2 years ago 10
@1994supra he started from <3k RPM, which means he didnt have all ports open. If you have any concept of renesis, you would know that renesis doesn't go full throttle till you hit 5.5k+ on RPM, not matter how much you step on it.

You can turbo the rx8. Infact greddy have a nice turbo for daily use.
BUT, you will have to endure the constant changing of the rotary Seals, because they cant take the heat.

rey0176 3 years ago
I'm running low 14's on a good day stock. Yes an RX7 is faster, but it needs a turbo and about 15K more to its price tag to do it. Let's also not get in to the fact you will be rebuilding your rx7 motor all the time or dropping another 10k or so to put a LS motor in it. So you can actually drive it, w/o the worrie of it breaking.
aaronwlkr 3 years ago
What? Not hating on the 8 but you need to get your facts straight. A stock FD runs 14's, and a lightly modified TII can run 14's as well. Not to take away from the 8 though considering that it N/A but don't hate.

If your referring to a CVT Automatic that would be true, however traditional automatics do have set gear ratios. The torque converter allows slippage which might give you the impression that it changes.

Just curious. Exactly how does some computer chip simply lift the redline? I mean redline isn't dependent on the car's ECU, isn't it more dependent on its engine, internals, etc. You can't just lift it with a chip without hurting it no?
KuostA 4 years ago
the reason the rx8 engines redlines at 9200 is because it stops making power at around 8600 and there is no need to keep reving....the rx8 engine has been tested to function safely up to 14,000 rpms.....so with mods you make power beyond 8600 so you need higher redline to use the power....
JenShultz 4 years ago
ermm..but redline isn't really set just by "when the car stops making power", redline is the RPM range where just any higher would harm the engine. That's why they prevent you from going above a certain RPM. Mods just make more power on the path UP to redline, I still don't see why it would raise it..
KuostA 4 years ago
Maybe you should have read his post. Engine can keep going to 14,000 RPM, but wont make much power after 8,600. With aftermarket upgrades such as turbos, power is made well after 8600 and so this is no problem for the car.
blackXSpr 4 years ago
I see, good point.
KuostA 4 years ago
and rx8 is a rotary engine so it can get up to 9000 rpm easier than regular cars
kill3r1130 3 years ago
With that said, generally any car can reach above 9000 RPM with proper balancing but then you also have to take into consideration things like flywheels shattering and the like.
Mutaku 3 years ago
What? Not generally "Any Car" can touch 9000 rpm let alone ABOVE 9000rpm. Proper balancing? Try, new cams, stronger valves, forged pistons, new connecting linkages...
You would need a lot to get an internal combustion engine to reach 9000 rpm. Every moving part poses a possibility of something breaking. Average engine redline is gonna be somewhere near 6000. Giving it a 1/2 increase is NOT easy.
blackXSpr 3 years ago
Never said it was easy. Also never said it would last long either lol
Mutaku 3 years ago
Then whats the point of comparing them? This engine, STOCK, will go to 14K RPM.
Thats like talking about planes and saying yeah, ANY transport vessel can reach 9000 ft cruising altitude, it just takes jets and wings but i never said it was easy.
blackXSpr 3 years ago
i dont know about 14k rpm's. that requries lighter rotors, larger porting, better intake and exhaust, and a newly tuned ecu. not even drag rotaries get that high.
Truenofan 3 years ago
haha... no... Mazda themselves have tested a completely stock RX8 engine up to 14k.
The reason drag rotaries and street rotaries dont go that high is they stop producing power at about 7000rpm. Piston engines need lighter pistons, stronger rods, all sorts of stuff for such high RPMs. Rotaries are not so because they have so fewer moving parts they can safely reach higher RPMs on weaker components. Get your facts straight bucko.
blackXSpr 3 years ago
truenofan is right, lighter rotors, stronger stationary gears, peripheral port and standalone ecu, also possible a de-rated water and oil pump to prevent cavitation. drag rotaries are usually turbo no need to go higher than 7k for turbo, more boost works just as well and as for a setup for 14k for the street at idle it would suck balls.
hhn2002 2 years ago
Im sorry but where is your source? What your saying, ISNT true, and no need to go higher than 7k for a turbo? WHAT? The MORE the RPMs, the more the turbo will CONTINUE making additional power. With a turbo it makes sense to push it to 14k but N/A as they are sold, mazda limits them to the 9k or whatever it is because they make less power. You are wrong about this and nothing yuo say makes sense. An engine capable of 14K revs can idle just as smooth as any other engine. God damn...
blackXSpr 2 years ago
a turbo will not necessarily simply continue making power with rpm. ignition advance has to be set sooner the higher the rpm. with turbos you cant set them as soon as n/a cars because you will get detonation and destruction of motor. if it makes sense why isnt anyone doing it with mid to high boost?
why do some engines make most power at 9k but some race motors at 14k? all because the size of the port needs to be bigger for higher rpm. renesis ports are too small or 14k.
hhn2002 2 years ago
Yes, a turbo will continue making power at RPM because the exhaust gasses only increase in speed and pressure as RPM increases. I never mentioned anything about setting ignition before, and that is something that is EASILY doable and not a restrictor of RPM or turbo. People ARE doing it, thats the thing. You just may not realise it. And some engines make most power at 9k and some at 14k because they are different motors, different cams, and different timing profiles. It is NOT
blackXSpr 2 years ago
my last sentence i meant to say "the renesis ports are too small for 14k rpms"
hhn2002 2 years ago
NOT entirely because of port size like you act like it is. Renesis ports are big enough to go UP TO 14k, but the ports are so small they stop efficently making power (stop mixing A/F ratio properly enough) above 9k or so. THEY STOP MAKING POWER ABOVE 9K BUT THEY CAN EASILY REV TO 14K. The transmission is also another huge limiting factor, in that if they COULD make power above 9k the tranny couldnt handle it. The last limting factor is the eccentric shaft, easily upgradeable though.
blackXSpr 2 years ago
he wasnt saying the engine is or isnt capable of revs. Nor was he saying how smooth it would idle. The point was that an engine that revs to 14k certainly has a HP peak in the later rpms and therefore would have no balls at low rpm (sitting at a red). Low end power best suits city driving because of all the stop and go.
amadisdemitrius 2 years ago
Actually he said a rotary would require a lot of aftermarket components like new internals to reach 14K rpms. So yes, he was saying it wasnt capable of 14K rpms. He also mentioned that a engine capable of reaching 14K rpms wont idle smoothly.
Your post says an engine that revs to 14K has no balls low end. This isnt neccesarily true, its entirely dependent on the engine. Rotaries dont make a lot of torque low end because they have less combustions and combustion chambers than similar ICE.
blackXSpr 2 years ago
"as for a setup for 14k for the street at idle it would suck balls. " is what he said which isnt indicating how smooth it would idle. I believe he was saying what i did about the low hp at low rev. and no high rpm engines wouldnt "necessarily" have low hp at low rev, but they dont. Any 14k rpm motor that outputs max hp at lower rpm would disintigrate at 14k rpm.The cam designed for low rpm hp wouldnt handle the high revs.
amadisdemitrius 2 years ago
Saying something sucks at idle means "when it isnt moving" because thats what idle is. Saying it sucks at idle is NOT saying it has no low end toruqe.
I never said an engine will be able to have low end HP and no top end HP. You can have more low end torque than high end (and almost always do). An engine CAN have low AND top end power. Thats what I said, and that is true. I didnt say an engine would make 500 hp at 700rpm then 100 hp at 70000 rpm. Because no, that isnt possible.

sjf91 2 years ago
Yah, Formula Mazda's use the Renesis, they rev to around 10,000 and put out about 280hp. The determining factor on the RX8 isn't that the engine can't rev that high, its that they couldn't build a transmission that'd meet those demands, and last long enough to be used on a street car.
striketalonx 3 years ago
Street RX-8s also use the Renesis; but the racing version is a 3 rotor not a 2 rotor that is the key difference. The 3-rotor race version also made around 400hp; not 280.
And actually transmissions have trouble dealing with power not necessarily just a high RPM band. Formula 1 transmissions last for awhile; a lot longer than the engines.
blackXSpr 3 years ago
Check your facts: Speedsource RX8's (the GT-class RX8's) use three rotar 20B's with around 415bhp.
Look up Formula Mazda Pro's. They use two rotar Renesis, pumping anywhere from 250 to 280hp.
True on the last point, but if you research the limiting factor on the RX8's red line, its usually the transmission thats listed as the problem.
striketalonx 3 years ago
yeah im not sure about what engine is in the three rotor but above 9000 rpm or so the engine starts making less power
blackXSpr 3 years ago
the 3 rotor is out of the mazda eunos cosmo, made between 1990 - 1995 and revd's upto around 6k, mind you it was no slouch at 300hp and 300ft/lb with 10PSI
rotaries the more rotors you have the lower the RPM you need to make and sustain power.
