I want to compare the pros and cons of supercharging vs a full on turbo kit.

I'm very fond of supercharging personally, espetially with a good intercooler like the Saleen. Superchaging is all American, has no lag, and doesn't ruin the exhaut.

Unfortunatly I'm also big on two contradictory things, horsepower and reliability. So I'm looking to judge if maybe a turbo is more my kind of thing.

In any case, I'd appreciate if some one posted dyno sheets for Mustang GT's running at 9 or 10 PSI on a turbo, and on a S/C. These should be the most common to compare which is why I'm shooting for them, but if anyone can find two systems running at similar psi, I'd want to see that.

Here is a sheet from a twin turbo. I believe it was 9 psi.

9+9=18 PSI?

As far as I know that is not the case.
9psi going into another 9psi = 9psi. its kind of like if you have 0psi goinginto another 0psi you still get 0psi.

he doesn't mean a car with BOTH a turbo
and a s/c

he just wants to compare the two systems

That and probably just a system on stock internals. Theres now way you can get a safe 700 rwhp out of our stock 4.6L's. I think meangreen was getting the 9+9=18 from the Twin Turbo chart.

I think he just wants 9psi kit charts for both.

hammeron

ah, good point

Id search for you but my forum search function doesnt work.

Also, is that for a v6 or v8? I am assuming v8.

Whipple @ 11psi.

452rwhp/444tq on 91 OCT. Since had a dyno using supplied 94OCT tune and Sunoco 94Ultra fueland got 467rwhp. Can't feel the difference between them on the old butt-meter though.

Here's mine for the Paxton set-up.
