Man I am tired of hearing different stories of what a F22 stock internals will hold in HP. Yeah we know the pistons the weakest link. Yeah we know the sleeves are cast iron. But Im tired of hearing people talk about there 335whp on a stock SOHC f22. Then I hear they only hold 250hp, Then you have the few stating that theres blew up at 230hp. I dont want to know what is the safest and dangerous boost psi. Who knows the amount of CFM can the block hold ? What could be done as far as upgrades (turbo, injectors, exhaust, ect) to achieve 335whp on stock Block w/ Stock internals ? If the block is capable of holding 250whp then why would a motor blow with less horse power? Ok I know milage has a factor . Lets say its around 20-40k miles.
