Im thinking about squeezing out a little more power out of the twins. Figure 12 pounds, pettit ecu, intake, full 3" exhaust w/ high flow cat and supra fuel pump on a low mileage reman - no ports. Now I just replaced my clutch 5k miles ago with the rotary performance's standard clutch kit which claims to hold 15% more power than stock. When the above mods are in, would this clutch struggle or will it hold the power for a few thousand more miles? Im just not too sure what kind of power I'll be looking at with what Im planning to put on compared to what a typical stock clutch can hold for a length of time.

 

Whats the harm it will hold for awile ok. I ran stock clutch with 326 to the wheels.

 

Based on experience, I'd say that the stock clutch is hard pressed to hold stock power, especially once the disk starts to wear. It would not hold 12# and a downpipe on my FD.... I would expect that the +15% clutch may be ok--at least for a while. Might as well use it since it's in there....

 

My original clutch @ 75k miles is holding 14psi just find, this includes autocross and track events.

 

it might have an elastic feel to it

 

It should be fine. If it had 50K on it, that might be another story.

 

ran 12psi from 39k to 72k before it started slippin..
dragged.. autocrossed and tracked...
