How much RWHP on a stock motor?
 

I am just wondering how much rwhp I can go before I need to build the motor. I would like to go Full BPU and run a t04s kit. Will i need to build the motor?
thanks

Guess you don't read the stickies...tell us for what kinda car...

sorry its a 94 model.

in theory, the stock apex seals can hold up to 800hp, but it never happens, a blitz sponsored car from japan was running 9.9's on stock apex seals, but that is the exception. Usually, people find a way too blow the motor. Too make big HP numbers, you should street port the motor and upgrade to 2mm hurley apex seals, which are actually softer, and flex more, which allows them to take more punishment. Youll need to upgrade the fuel system, and run a standalone or something close for a computer.

Well I guess my ? is how much rwhp can I do before I need to start looking for a failure point.

2mm why not 3mm?

About 500...

Increased friction from the thicker seals...
Unnecessary unless you want slightly safer buffer from mis-tuning.

PFS has claimed 23psi of boost on a 10-second drag car with stock 2mm, 3-piece apex seals if you keep it out of detonation...
