  • I want one so badly I can taste it.

  • how much does this kit run for?

  • Dude in the top comment doesn't know what hes talking about... Horsepower is how fast your car can go as in top speed and torque is how fast your car gets there as in acceleration... horsepower doesn't kick in til half way through any race so torque matters a lot

  • @huntyourmama wow! you know nothing about the physics behind cars do you?

  • @FoxhoundJay Horsepower is how fast your car applies torque... If your car is throwing to much torque and it doesn't have enough horsepower to handle it then your acceleration will suffer cause it will be hitting its top speed before the engine can raise it by working harder to allow the force from torque to go through it. Your mission in a race (I'm talking about dragging anyway) is to keep torque going as long as possible.

  • Nice RX-8 bro!

  • What? 327? NIII....

  • @FlUdDeStRoYeR94

    I said "NIIICE!!!"

  • Those rims looks like viper rims.

  • never seen a supercharged one

  • LOL to the guy at the end...  NIII FGIBDOIGDSOGODS

  • RX 8s are gay, I know i shouldn't be watching if I dont like... but they look nice

  • @MINI14ification ur gay...

  • good sounding 8. what is the torque that you made? btw @h2h2h2h2 torque ISN'T just for towing cars.. i know you're being sarcastic, but torque is just as important. and the 8 isn't as lightweight as you would hope it would be.. 3100-3200 lbs (+SC and driver) isn't light. in a miata (or even an rx7) it would be less of an issue..

  • @silntinsnty As Carroll Shelby once said, horsepower is for bragging rights, torque is for winning races.

  • @acekazel ehhh, the only non-american company worried about torque is Mercedes. Otherwise all the others get big horse out of smaller engines.

  • @noobasdfjkl BMW and Mitsubishi are good examples of more horsepower per cylinder, also subaru. BMW's pull insane amounts of horsepower out of their engines, and mitsubishi had a 456bhp 4 cylinder engine for a while. and subaru is known for their straight 4 cylinder that you tune yourself.

  • @LtColQwerty indeed.

  • @LtColQwerty You're one of the dumbest people I've seen on here in weeks.

  • Comment removed

  • @acekazel actually all i have to say is 3 letters... BMW and i usually win races... lol

  • the rx8 was 3 car's ago lol... we have since got a mazda 6 v6 then got rid of it.. now we have a 2010 mazda cx9.. (got 2 kids now)... also picked up an srt-4 for a daily driver.

  • does anyone know how much torque is being produced? abit skeptical about a supercharged high revving. just a guess here but surely a turbo charger would give this car the extra punch; and by punch i mean torque

  • How much lb/ft of torque did you make with that setup?

  • Anyone know what body kit that is?

  • cool

  • Proud owner of a Rex

  • When I find a way to import the Pettit SC to South Africa I will definitely buy it!

    Then I'll show my older brother's Nissan s13 (sr20det) whats up! haha

  • How muchh that costt????

  • if I could get 300rwhp on my R3 Im a happy man.

  • o cool I live in kissimmee, Im trying to find hook ups for my 240sx

  • lol NIIIIICE

  • this car needs torque above all things! any ideas with torque and this kit?

  • Torque is for towing.  Car is already light weight, so it's not an issue unless you weigh 600 lbs.

  • @h2h2h2h2 you would be very surprised as to how much torque makes a difference, especially in lower rpms. And if you know rx8's, the powerband starts at like 4000rpm, so anything below that range is usless b/c it has no torque. This engine's only advantage is its 9000rpm redline, so when the other guy is shifting @ 6-7k rpm, your still in ur powerband, meaning u shift less...problem is it takes you forever to get to ur powerband b/c you have no low end torque...fatal flaw

  • You just have to keep the revs high above 5k+, and shift just before redline and make sure it doesn't drop below 5k. Sure it could use 2x low-end torque, but considering it's only a 1.3L that might be asking too much.

  • Actually I believe what they are doing with the new RX7 that's coming out, is making the rotors larger for more low-end torque, but thinner to cut down on weight. Was supposed to be released this year, but there are some major problems that still need to be fixed - mainly the fuel consumption and oil issues.

  • @mtooshort20 Power band is really more like 5000 and up, and it doesn't take you a long time to get above 5000 rpms because you launch at 6000 rpms, then as you shift at 9000 your rpms, you are only dropping down to 7500, which means you are always above 5000. Unless of course you are launching your car like a girly man and granny shifting each gear, but that probably won't be the case if your trying to go fast.

  • @h2h2h2h2 except for getting it moving. It already revs up to 9k so it already has a nice top end power but has almost no torque and in the words of carroll shelby. "horsepower sells cars, torque wins races"

  • @h2h2h2h2 3000 is lightweight? it has a 1.3, most cars with 1.3's are geo's. this car should weigh mid to low 2k's.

  • @firechicken76 But stil you have seating for 4 in relatively fine comfort and it actually has a trunk :-) If a 2 seater would be as you suggest but otherwise it is just uderstandably weighted. Chassis is quite sturdy for this setup... Look at Acura NSX - fewer compromises and stil weight is only slightly under 3000 too - weights about 2800 to 2970+ depending on year (newer is lighter). So no problem there in my oppinion.

  • @h2h2h2h2

    It's not so light that you can ignore torque. Don't forget how horsepower is calculated.

  • Naturally, torque will go up with HP. Go to the Petite Racing website, they list the torque / HP for their RX8 Supercharger Kit.

  • your backwards hp goes up with torque not the other way around. hp is created from torque and rpm.

  • In that case, with the little amount of torque, it has a shit-load of HP.

  • Have where that make let exactly and cost what it you of price? in the Germany knows itself no therewith from. At least I know no and I would like unconditionally in mean incorporate.

  • thats about 360hp at the crank which is how all the manufacters rate there hp publicly thats about 8.3lbs per hp pretty good

  • but a straight 6 in dat from a porche and twin supercharge it and u hav a hell of a car :D

  • @xXP5YCHOXx uhm. youre watching an mazda rx8 video, not a porsche video gtfo and quit trollin

  • why would someone dirty this car by putting a porsche engine in it. That guy needs to get a clue and understand that when we want more power in our R8 we go 3 or 4 rotor and turbo charge and make V6 and V8 look slow and stupid.

  • you are tarded.....everyone knows that once the roto blows on this car, they are going to put an ls3 in there.

  • even better off with a 3-rotor, though. lighter and comparable power

  • porches dont have inlines, they have boxers.

  • I guess I missed Porsche producing straight 6 engines. Pretty familiar with BMW's inline sixes. Porche makes boxer (opposed) sixes.

  • that car is beautiful

  • too much hp for its own good lol

  • haha, "327?, niice"

  • and you are from MICHIGAN

  • I bet this engine would make use of a tune pipe better the a free flow exhaust system the way runs is two srtokish nature.

    fires every revolution of the crank shaft.

  • What?

  • how much does it cost to supercharge a rx-8 ?

  • we bought my fiance a mazda rx8 6 speed. im trying to figure out what we can do with it. Dont want crazy power but somewhere in the 300whp range is nice. any way we can get that kind of power n/a without going with the tri rotor? Dont want turbo charged cuz we already have that. do they make belt driven superchargers for the rx8?

  • The Pettit Racing Supercharger is belt driven (not turbo) and it makes close to 300 whp out of the box.

    No way to get that kind of hp NA with this engine.

  • 300 whp from a peri port shouldnt be a problem. mmm, peripheral p renesis........plus the fortune worth of goodies needed to make sure it doesnt blow straight away.

  • you could actually achieve 300hp, but you would need to do very serious tuning like intensive porting and short runner ITBs and you would have to spin it upwards of 12000rpm or more.........probably not the powerband you're looking for

  • yeaaaaaaaaa thats a lil overkill....

  • Are you talking 300 bhp or 300 whp? The car in this video is making 327 whp, which probably equates to 380-390 bhp.

    I don't know if anyone has tried to spin a Renesis up to 12000 rpms.

  • well, RE Amemiya has a NA 20b with Renesis rotors (higher compression) pushing 500+whp at about 11K RPM with MSP rotors, so a two rotor renesis could probably manage around 300whp. F/I increases HP by increasing torque at stock RPM band, porting and spinning to 11K increases HP by mutiplying the stockish torque levels. There are 13b's with MSP rotors pushing these powerlevels, but I dont have an all Renesis example handy... but F/I, esp S/C provides a more drivable powerband still IMO

  • i know a mechanic that works on rotors and has had a few rx8s come through, stock it can rev to 13k. powerband stops so much lower so its limited. provided uve got the right setup and tune, he said u can push it to 12k every day. (not a piston, the revs are good for it)

  • your an idiot.

    stock 6spd rx8's have a 9k rpm redline with a 9400rpm limit.

    to have a rotary spin to "12k everyday" the motor needs to be extremely and meticulously lightened and balanced, and the eccentric shaft needs to be as close to "true straightness" as possible.

    Not to mention the very close bearing tolerances.

    Race built rotaries spin above 10k+

    But commonly they still rev to 8-9k rpm.

    educate yourself. do some research before posting inaccurate info.

  • even though ive got evidence, you're still ignorant enough to call me an idiot? 'race built' rotors dont use the rx8 high compression rotors or anything from the renesis. And typical rotor tuners choose to keep the revs below 7k for immediate power, thats the tradeoff for a high redline, not to mention reduced engine life. My info is straight from the horse's mouth, urs is after hours of youtubing, wiki and generalisation. btw, u dont need to tell me stats about my own car.

  • Please......

    Since the Renesis was released, the most commonly used rotors for an n/a application was the Renesis rotors' 10:1 compression.

    It wasnt till then that people were using S5 n/a rotors.

    Yes, a race built n/a motor CAN use rx8 rotors, if the builder or car owner chooses.

    It has been done many times over and has made significant results, especially when the last resort of all out power is going with a peripheral port.

  • Some people even use the RX-8's eccentric shaft because it is much lighter than previous.

    Who is this "horse" that you heard your info from? Im curious. Because if he was a specialist in rotary building and tuning, he would already know what i've said is true.

    Apparently, your insults aren't that much different from those people who curse.

    You just went about it a different way trying to use two very subjective and completely inaccurate sources.

    Generalization my ass.

    I build rotaries too.

  • well if they are using the renesis rotors so much why is it that when mazda used them in there 13b rew race car they found it produced less power and went back to the original rotors? and yes the rx8 can rev to 13k stock after that the harmonics of the engine will shake the engine apart. im sure the power would suffer a lot reving that high with no intake or fuel mods but it can still do it. as far as daily driver goes probably not, reliability would suffer and it would be hard to drive daily.

  • What evidence do you have?

    I have built a few high-rpm race rotaries.... but they were all peripheral ported motors, some with rx-8 rotors and shafts. In addition to the 8's shaft being lighter, its also cheaper.

    To rev and make power up to and above 10k rpm, a massive bridge-port such as a J-bridge or the extreme of a peripheral port come to play.

    The stock ports of ANY rotary, even if its an aggressive streetport, do not flow enough air to support over 10k rpm.

  • @overclocked28 ......um 12000 I'm not sure about that. But the tach is off and I use to have my interceptor set ya 10k and from the gauge to the interceptor was almost 1000 rpms different. So I'm pretty sure I reved 11000...but then again those first gears was so quick if you push in the clutch just right the engine could of turned up to 12000 for a sec. But 10k is very doable without a doubt.

  • @overclocked28 renesis @12000rpm's ?? want to see this !! ;)

  • @jeveuxunemoto I wouldn't want to see it... unless I'm behind bullet-proof glass :)

  • @overclocked28 It's pointless to go over 9.5k RPMS from what i understand... the stock renny can do it but no power to be had there.

  • @overclocked28 engine can handle it but the tranny will explode through your legs.

  • @overclocked28 Actually the renesis can spin up to 14000 rpms before vibrations tear it apart...12000 probably isn't very reliable though haha

  • @jeveuxunemoto a renesis can handle 1400rpm's. Mazda just made the redline @9000 because it starts to loose a lil power after that. and plus the transmission it has factory wouldnt be able to take it

  • @overclocked28 arent brake hp an wheel hp the same? flywheel hp is different. and no one uses flywheel hp but car companies and companies trying to sell stuff.

  • @overclocked28 renesis engines are tested at 14500 rpms before they get passed to go into rx8s.

  • @chabbalato yea and that wouldnt b very street friendly at all cops would b like WTF under that hood making all that racket!? lol would b cool tho.

  • @youngonesunique go buy ECU with proper setting made for u're car u will take the power u want

  • @youngonesunique, do you already have a deep core intercooler in front of the radiator? is there a large racing air filter connected to the intercooler? If you pipe the filter to the intercooler, have the filter in a place where fresh air entering the front bumper can reach it @ speed but rain can't, like behind or under the headlight housing. Then replace exhaust (the "cat" to the muffler) with highflow "cat" & larger diameter straight pipe to the back made of slick metal like stainless steel.

  • wat kind of pulleys and headers does ur car have?

  • at the time of the videos, that car had the exoticspeed header. The SC pulley is the Pettit SC IV if that is what you are asking.

    It's my friend's car btw, mine is in the 281 rwhp vid.

  • hey man how do you like the headers? i saw the ES header/exhaust combo on ebay that i want to get so bad. rotary's for the win!!!

  • 13b pp?

  • 13b RENESIS (msp) :)

  • Do you remember how much torque he put down? The highest amount I've seen from a Pettit kit was 201, but that RX8 had about 300 rwhp too.

  • 214

  • hey is that the nrg or tien hood dampner u have?

  • Tein

  • how did you make so much power with that kit!!??

  • This isn't my car, it belongs to a good friend of mine. My car dynoed 281 w/ the same kit on the same dyno immediately after his 330 rwhp run which I didn't catch on video. The differences between his car and mine are: a bigger main pulley, bigger fuel injectors, and headers. The headers give him 5-10 whp, the pulley and the injectors give him 39-44 whp (he's 49 whp higher than mine). Our cars had virtually identical dynos before these upgrades.

  • hey isnt this Marsredr100's car? Btw what is your name on the rx-8club?

    Please don't tell me it's r0tor...

  • Yes, that's his car.

    Bastage

  • Hey wat's your name on the rx-8 club?

  • Bastage

  • oh ok sorry, i didnt read the bottom part of your comment when you said bastage.

  • just wondering, how much did your mpg change after the supercharger?

  • Similar to stock while cruising.

  • damn 327whp? That must be atleast 385hp to the crank. That's almost double the stock power, good job.

  • Huge power and sounds awesone, congrats!
