Around 450-500 flywheel horsepower is safe on stock internals. Anything above 500hp is really pushing it. Don't forget that designing an efficient turbo setup and properly tuning your ECU is critical to the longevity of the engine.
The f22b1 is a great engine for boost it has a compression of 8.8:1 and can handle 12.1:1 so you boost about 11-12lbs. On the stock internals no problem.
Stock turbo can run close to 14 PSI...but you can increase as much as your turbo can. The engine will not last as long with higher boost. Upgrading internals such as pistons, rods, crankshaft, camshaft, and valves can allow much higher boost.
Depends on how many pounds of boost you set it to, but 500-620 if you dont destroy the stock internals lol.
7 psi is safe to boost on a stock d-series motor
Stock is around 9psi.
8psi
about 60psi
You're best bet is to only use 6-8 psi because there internals are not capable of to much boost. You should also take a look at the mileage you're engine has. Good luck just don't screw the engine up.
As much as the waste gate is set at, size of the turbo, size and a/r of the turbine housing. "How much you can run" depends on... the strength of the engine(forged internals?) compression ratio if iron or alum. head head gasket material/ head bolts or studs Intercooled/alcohol injected the octance fuel you are running If it is a normally aspirated 3.8L, 7-8psi is the general safe boost level for stock engine.
With the motor being only 8.5:1 compression i have been told that it can easily hold up to 20psi with stock internals, and ive even seen 36psi run on a stock bottom end. Personally i wouldn't trust running 20psi so i knocked mine back a little bit to 16-18psi.
3.8 inch pulley at 7-8psi
6-8
