I want to put a supercharger on a 5.0. The engine wont be stock when it goes on but, the compresion ratio will be. I want to run the most PSI I can but not put my engine at risk.</P>


What will be the optimum PSI on a 5.0 with stock compresion ratio???</P>


What is the best low-maintenance supercharger???</P>

If you're gonna have a non-stock motor, drop the compression ratio. It'll allow for more boost without detonating the motor to hell and back.

I know people running 17 lbs on stock 5.0's

churk..not for long</P>


I say 7-9 is about it....still put on a pressure relief valve</P>


I run 15psi on mine with flat tops..</P>

I find that difficult to believe that someone could do that and the motor lasted for more than 1 full throttle run</P>

Get forged internals and good electronics (and tuning) and you can run more boost. You said stock compression ratio, but are you going to change out the parts?

I'm actually not sure what I want to do. I want more power so I need to do one of a few things. I can either lower the compression and run a super/turbo charger or I can just raise the compression. My question should have been, which is a better idea? I don't want to have to use jet fuel just premium. And no offense but, 17 PSI on stock engine, I think you missunderstood.</P>

Geta DSS Super Pro Bullit long block 306, that will hold down lots and lots of boost. I plan on myself buying a DSS Super Pro Bullit with Canfield comp heads, anderson blower cam, and runing either a vortech or a intercooled procharger D1 or F1 blower. <IMG src=smileys/smiley14.gif border="0"> And ya a stock motor with 17 psi would prolly blow up the first time it met wide open throttle

And you would want compression in the mid to low 8 range.

well if planned right you could go with stock type flat tops( forged pistons) as I did..no problem as I run 15 psi... I have the dss short block a fairly larger crane roller o-ringed heads, pistons are fly cut, and most important a high $$ blow off valve if I decided to pull the vortech and go to something else I'm not stuck with low compression. but if your not going over 7-8 pounds I would go the flat top way...
