just wondering if anyone has done it or if its even safe. stock ap1 with 9.5 or even 10.0 FMR pistons. power goal is 375 on a custom kit im working on.

 

375 on a sc? tc? what boost? and is 375whp? or crank?

People are making lots more power than 375 on stock everything.

 

Yeah no sense in lowering comp for just 375whp. Your better off leaving the motor un-cracked and left stock for anything under 500whp reasonably. A good tuner on pump ...or even better with water/meth will get you safely there. The stock motor is all forged from the factory, so the only point in building a low comp motor is because your power output exceeds your ability to control detonation through tuning means. 375whp isnt even close.

 

ok cool thanks, i was always wondering about that. its gonna be a custom turbo im building. thanks guys
