Ok guys im about finish my lastest block. I need to know how much boost that my stock sleeves can handle.

setup:
f22b1 with 11:1 cr
SS valves
crower rod
wisco pistons
and all ur fuel and ignition stuff.

im currently in search for a stand alone.

 

They are capable of handling at least 400whp. Compression doesnt matter how much boost you can run on your stock sleeves, its in the tuning that matters. Reduce the cylinder pressures and you'll save the sleeves alot of deformation and shearing forces.

 

what do u mean by reducing the cylinder pressure? do u mean lower CR?

thanks
