The other day one of my friends told me about rx8s after a few mods can go up to about 15 or 16 rpm before car gose boom lol . Ive looked for a while and havent found much on this. Was wondering if you guys know anything about this and if theres any thurth behind this .

Thanks

 

No truth and it would be dangerous.

 

parts in the transmission would fly apart before the engine ... but going to 16k rpm is worthless right now since the engine peaks around 8700 rpm.

 

You could change that by changing the tune but regardless in stock trim you are correct.

 

so it could happen with better tran and fly wheel etc but would be worthless

 

I don't know if even the massive renesis ports could bring in enough air to make power at that kind of RPM. Not to mention getting an ignition or fueling system to keep up.

 

well i am sure it would destory the car . i see how easy it is to redline the car and it seems to take it so well so thats why i just didnt lol at him i had to look into it.

 

All the tuning in the world won't allow the engine to hit those rpms. Even if you opened up the ports to somehow make it breathe better and optimized the intake and exhaust, you still couldn't hit that rpm. It would take a total redesign of the engine to do so. Specifically you'd have to use much smaller rotors as the current ones are way too heavy. The bearings would die a harsh death. It seems nice to think that the rotary can rev real high but it is still limited to physics and bearing limits. Also consider the fact that you'd need one hell of an ignition system to fire intensely enough at such fast rates.

 

dude what are you guys talking about.....

it goes to about 17.5K rpms......try it out

 

Just cut off all red lines comming to your ECU, this will cut off your RPM Limiter.

 

rev pass the 10000 mark, then past the 3 o'clock mark and watch the needle pop out.

 

Even the Honda CBR1000RR sport bike's redline doesn't exceed 12.5k.
The 600cc version redlines at 15k.

 

I saw a guy in an FC without a revlimiter rev it to 12K, his transmission exploded and he was sent to the hospital, his tranny saftey net saved his life.

I.O.W. dont do it.

 

i was thinking of about 13-14k would probably be the very limit of the renesis

 

Just shift into first on the highway.

 

I'll bet that it's nowhere even close to that high. You never want to top 10,000 rpm on a street car anyways. Even if the engine has the ability to do it.

 

I don't know about you guys.. but i'm in love with my rx-8.. and would never hurt her like that. =)

 

I need to find the chart that shows bearing stresses in relation to rpm. After you top 7000 rpm, the stresses really rise at a very sharp rate. It appears to be an exponential curve. It'll be a wake up call to many who think higher rpms are better.

 

it could be possible with a quad rotor engine with smaller&lightened rotors and a lot more fuel/air.... but it would destroy the engine reving upto 12k

 

thanks for telling me before I go do something stupid :D

 

yeah, two words before you go crazy exploring rev limits:

ballistic blankets

 

kinda off topic here, but anyone know if they make a scatter shield for the RX8. I see people putting these 8lb flywheels in and shudder when I see where the flywheel is compared to my legs. I'm scared enough with a 9k rev limit.

 

Aye! 'Tis called chain mail!

 

Had tried once reached 10k rpm. But after battery change, somehow only can reach 9.5k before cut. After less than 30 times 9.5k rpm, engine blew. Paid about US$6k for a complete rebuilt from Autoexe Japan, including transport and workmanship at my country. http://www.autoexe.co.jp/products/fi...inetuning.html . After 3 months of reviewing, I finally found that is not worth to go for that high rpm. Because it won't lead you to anywhere. And I also found that the car is a lot faster if can make the gear change smoother. If that is not enough, nothing worth more than a 20B http://www.coconut.se/akira/20b/20b%20re-a1.jpg

 

Thats a costly mistake my friend. Whats the point in going past 8k.............. there isn't one
