Thread: Procharger Blown 383

ok....im no professional but here are some things i know about making boost. i know a cent. supercharger is more efficient as far as heat goes. here are some factors that can help you to be able to run as much boost as possible. boost is better than compression, btw.

1. dish pistons or flat top pistons will work. i'd buy dish unless you already have the parts for the engine.

2. a std. bore (or close to it) can take a little bit more boost because the thicker the cylinder walls are the less heat the motor is gonna make. less heat means less detonation

3. heads with big combustion chambers. the motor im building is gonna have a set of gm iron heads that have 76 cc chambers. but they have been ported so that gives me even less compression.

4. thick head gasket will create less compression

5. big valves......the exhaust valve needs to be big to let the heat out of the head. less heat=less detonation

6. also, im not sure but is that a blower or nitrous cam? because for forced induction you need a greater lobe separation. (112-114) procharger also calls for the exhaust duration to be 10-14 degrees greater than the intake.

7. intercooler-you'll definately be able to run more boost by running an intercooler.

procharger sells different sized pulleys to adjust your boost to as high as you want it

i know this is alot to read but i hope it helps you out a little bit.

im doing everything i can on the motor im building to be able to run around 15 lbs. of boost. it wont be intercooled though. if i can run 15 lbs. of boost on my motor....it should be around 800 hp.
