Auto 4 ports max RPM ?
 

Hello,

My question is simple. What the max rpm rev the rx-8 4 ports ? Stock ? and after modification ?

Tkank you,

stock should be 7500, and modified....OVER 9000!

Maximum efficiency of said rpm band: about 8K.
after that, no increased benefit is gained.

Tkank you !!

curious, is it even worth just upping the RPM limit with the AT?

bump on that question. 7k-8k im not feeling too much torque :crying:

although i do like the beep :)

No its not after 8k that is the peak for the 4 port. There is no gain after 8k.

i dont know about a 4port, but on the 6port auto it gave me a tremendous bump

Of course it would. you have 2 extra ports, therefore the motor can injest more air at said rpm.
