Hi

Anyone have done this? or is possible put the renesis rotor assembly on a 13b s4? what the changes that we have to do on rotors? Possible gains?

regards

 

its been done before, and doesnt to much of anything.

try tuning the car. would produce more of an efect.

 

Sorry, to revive an old thread, but isn't the compression on renesis rotors a lot higher? Like 10.5:1?

 

Compression on the RX8 is 10:1 on either the 4 port of 6 port version.

Here's a link to the RX8 specs. http://www.mazdausa.com/MusaWeb/disp...ode=RX8&bhcp=1

 

Compression helps significantly, but basically it's a lot of trouble for a little gain. The ports, tuning, etc. are more important.

 

Hi

In my opinion, more compression is much better, +power +better gas milenage.
But here in Portugal we have 98octanes Gas, detonation don't is a problem. And the renesis rotors are more lighter than the s5 rotors.

But I'm thincking on buy a lightweight assembly from racingbeat.

Lordy Bagordy!!!! $2300 to save 1 lb. per rotor!?!?! No thanks....

 

Anyone have test a engine with and with out the rotor assembly and mesure the diff? I think that less 2lb on an engine at 9000rpm/3 = 3000rpm rotor, will do very diff on performance!
