  • 1st gear 55mph

    2nd gear 85mph

    3d gear 131mph

    "Mustang V6 2011" :)

  • @ilibasic and then you break down.

  • i think that even for rotary engines it is dangerous to rich the red zone! why rx-8 has no cutter at 9000 rpm ?

  • rotory engine can redline at 15k but to pass emission tests they set it to 10 or 9..

  • I love the two top comments are essential the same comments. That's pretty awesome

  • can you explain to me what the point of this is?

  • 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

  • yeaaah.. sixty nine and ninety six.. yeaa

  • Rotary Engine FTW! you could co over to at least 12.000 RPM. Only there is a thing that avoids it - transmission ;)

  • Your head is a piece of shit. Rx8 is a very good car. You compare diferent things, with diferent prices.

  • @highbill ... lmfao.. i see alot of problems with these POS RX8.. oh wait, it is a POS. hahahahaha

    slow ass car...

  • @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. 

  • 2JZ engine sounds 100x better than this piece of shit.. my T-IS300 and T-Supra

  • @LightningMAS 2JZ engine sounds like an engine with pistons, which is very boring.

  • @PantstofryPWNZ u serious?? roflmfao.. 2JZ-GTE/Turbo = THE GOD of SOUND..

    i know your a n00b. i can tell.

  • @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

  • @PantstofryPWNZ your right... I do love the LSx motors, 2JZ motors, RB motors, and all exotic motors.

  • @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.

  • @PantstofryPWNZ yeah i agree i don't really follow hyundai but they're reallly bringing the heat now, i'm tired of seeing little elantra shitboxes on the road lol. the new ones are pretty cool. and the genesis/coupe is sexy

  • @anonymzs I have a new elantra haha, it's pretty cool. Saving up for an Audi TT to modify, yay!

  • i love the sound of rotary engines....

  • The redline isn't set by what the engine can safely do, but by the time it's at 9500 rpm it starts losing power and isn't worth revving any higher.

  • yepp once keeps the carbon away i do it near my house in the morning after letting it warm up .

  • ouch engine must be crying :(

  • "it's no hot rod"

    cmon man! It's a rwd mazda! it's badass! I'm sure you have so much fun taking corners with that grip machine

  • 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

  • That with the 4.60 rear end or whatever the hell they offer would rip it up.

  • they can take the abuse TRUST ME

    keep it well maintained and you'll see

  • 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.

  • 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 wearing out your rotor housing quickly.

  • your tranny must hate you

  • Clearly there are people here who know nothing about rotary engines and are just speaking with ignorance about things they know nothing about...

  • 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

  • @hotboyonfiyer lol kid knows nothing about Rotary engines... GTFO It's healthy to redline them and is recommended. I had a guy at my mazda dealership tell me to go out and let the engine breath as much as possible ( driving the piss out of it in other words) You're right mazda put that redline on there for a reason, Zoom Zoom, its not like your normal car.

  • @Roflamus So if you open the owners manual it will say "beat this shit out of it and run it WAY past redline" ?UR an idiot lol and you think a mazda dealer wont tell you to do that?They want you to break your shit so you will bring it into the dealer and they can make money off you dumbass.Why you think rotary motors are junk and last less than 100K miles most of the time? Cause you got idiots that think like you.If they wanted you to shift at 10Krpms they would have put the redline there genius

  • Comment removed

  • @hotboyonfiyer I had to replace the manifold and I was told it went out because I don't beat the shit out of it.

  • with that kind of treatment, that car will explode eventually :)

  • What does the scouter say about his RPM level?

  • RPM not RPMs ... its revolutions per minute not revolutions per minutes

  • Just wondering, is the beep as you get into the red stock?

  • @widowsmaiden1336 Yea every Rx8 makes that sound when you push into the red. The engine is so smooth you probably wouldn't even notice if the beep wasn't there or unless you were watching your tach.

  • whoa!, is this car in any way upgraded or stock? Cause I thought they only rev to like 9000-9200.?

  • 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.

  • how did you get it 2 redline higher?? mine cut at around 9.4

  • do you know how much stress you are putting on that engine....

  • @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.

  • @G77R It only makes sense to rev that high if the engine can breath at that RPM. The RENESIS (at least in stock form) plateaus at 8500RPM.

  • did u take the rev limiter off

    

  • omg 10000 gears??

  • wow, they tach up pretty slow without the turbo. my 93 rx-7 would red line in a second.

  • mine can do the same. its stock

  • i love how smooth it accelerates, it kind of takes the beating instead of thrashing like a piston engine

  • @FerrarisRock yea i dont like the sound that pistons make during red line...there like.....idk u just know there bout ta die soon lol

  • @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 keep the seals lubricated as well!

  • @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..

  • @paseo1997

    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.

  • @kakashithemimicninja yeah then he will start having idle issues and engine issues all together :) mwahahahahaahahahahahaha

  • i heard these engines do get tested to 13K-14K.

    but they do make a great noise tho

  • it just keeps going without caped torque

  • A little red line for a good time

  • sounds good

  • 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.

  • annoying beeping ever :/ i guess you can go to the car shop and ask to take off that beeping thingy

  • hahaha 69!!!

  • I am impressed the transmission will shift at almost 10K engine rpm. Must have quad syncros or some shit in it.

  • annoying rx8 redline beep.

  • Stock these motors can go well over 14K revs but they stop making power thats why artificial redline is at 9

    Learn your facts :)

  • not true man they only make it at 9700 cause after that u cant put a warrenty on the engine as its easy to blow apex seals aft 11,000

  • Mazda themselves have tested it up to 14,000

    do you research before saying i am wrong kthx

  • I used to know a guy who regularly revved his RX-7 up to about 13 grand!

  • pmsl? 13 grand u mean 13k or 13.000rpm u fol haha!:P

  • 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.

  • @xbartosx Yep... Maybe that was his damage cost. Lol

  • 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.

  • lol mine didnt last long whn i treated it like tht the gud thing is it kept reving no valves 2 bounce off lol now i got rebuild it

  • how much did the rebuild cost?

  • 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

  • free, since its covered under warrenty

  • lol my saab does 60 mph in second at 6 k redline

  • is that a digital rev metre? like the needle is digital? because if its not you think your doing 9700rpm but really your probably only doing 9000rpm

  • needle aint digital

  • so that means that hes actually doing 9000rpm not 9700 as the non digi needles become unacurate at high rev's

    cheers!

  • no it means that he is going 9700k, but

    SmellyCatPoo97 wished that his prius with tacky digital needle could get close to it.

    All manual rx8 can rev that far - but seeing that power drops off after 8.2-8.5k rpms going past 9 is not going to make it any faster

  • hahahaha okay hahahahhaaha crackup

  • k man ur not right an rx7 will say its doing 9700 but int s actualy doing 10000

  • No! Your wrong don't bother posting if you don't know anything.....

  • is long time for 1 gear and 2 gear and 3 and 4 ;;5 is not fast is fat

  • 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

  • OMFG MY HEAD IS GOING TO EXPLOOOOODE

  • jizz in my pants.

  • 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.

  • *as long as he doesnt do it all the time he can do it

  • To be honest, the engine is made for racing. Beat the piss out of it, just pre-mix and keep your oil topped off. ;)

  • and airplane appications

  • that as well. good point

  • It looks like it gives out of power right about when you shift.

  • my bike will do just over a 100mph cars nil bikes 1

  • 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 :)

  • 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.

    the Seals are cheap, but its troublesome to change.

  • to think your have a nice car, and you love to kill it...

  • 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.

  • That is wrong.

    You only change the rotary seals depending on your use.

  • Not true, with any rotary its all about keeping up on maintenance.

  • @AndyMac661

    and I was considering puting one in.

  • The redline on the 8 is to protect the transmission, not the engine. The engine can rev to redline all day long and not have a problem.

  • Pretty short gearing in those things actually...2nd gear at 2500 for 25 mph...i'm surprised.

  • The MPH went down a hair bit more after I put a 4.777 ring and pin in it.

  • that would be third at 25 is 2500 third yields 10 mph/1000 sixth is about 20 so at 2500 you are doing about 50

  • 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.

  • lol hot rod

  • not get any mad or any thing but auto dont have a set gear ratio they charge on different driving conditions

  • 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.

  • dude thouse cars can take all kinds of abouse you can rev them up to like 12000 and not harm them

  • well I wouldnt rev a stock rotor to 12,000rpm as you will probably pop an apex seal, but if you get upgraded apex seals you can.

  • Generally the issue is tuning.

  • 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.

  • I see, good point.

  • and rx8 is a rotary engine so it can get up to 9000 rpm easier than regular cars

  • 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.

  • Never said it was easy. Also never said it would last long either lol

  • 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

  • my last sentence i meant to say "the renesis ports are too small for 14k rpms"

  • 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.

  • So basically your comment is completely, entirely irrelevant of our discussion.

  • very inciteful. But it would make sense seeing as the engine is simpler.

  • 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.

  • 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.

  • yeah im not sure about what engine is in the three rotor but above 9000 rpm or so the engine starts making less power

  • 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.

  • according to mazda themselves. your engine power specifactions are wrong. the mazda pro class uses a standard renesis motor.

  • yah, but star mazda uses an tuned renesis. It is, at its core, a renesis, but tuned by mazdaspeed

  • lol my uncle used to work for mazda and he said they were forced to put a rev llimiter on it cos it would not stop revving!

  • Rx8 was tested up to 14K. Rotary engine can take a BEATING . I wouldn't trade mine for anything in it's class right now..

  • thats amazing I thougt they goveren at 9,000 rpm cool video.

  • 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?

  • Racing Beat is a company that made a computer reflash.

    Google up racing beat for more info

  • no offense but what is an rb flasher? im sorta new to this but i do get into it can someone tell me?

  • I show my friends this video all the time! that RB flash is worth every penny! nice video ! - Crazy rx-8 Driver from RX8club

  • 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
