mach 1 compression ratio
#2
A 2003 Mach 1 compression ratio is 10.1:1 and I think it is a little high for a supercharger although lots of people do it. A 03-04 Cobra runs 8.5:1 compression I believe and that works much better with the boost. Try the search forum option and you will get a lot of info on this stuff. Im only telling you what I have read on other threads here. Hopefully someone will chime in with a better answer.

With the mach's compression ratio being 10.1:1 all it means is you can't run as much boost safely. You can run 8lbs perfectly on the mach 1 motor, with the cobra motor (8.5:1) and its iron block vs our aluminum block it can run a significantly larger amount of boost without risk.

To be perfectly honest, because of the Mach 1's higher compression ratio, it responds nicely to a 100 shot of nitrous! As far as supercharging goes, there are plenty of low boost options out there that are perfectly safe. I wouldn't run past 8-10lbs. under any circumstances on a stock block Mach 1! The aluminum block is by no means the weak point, it's the rods and pistons that can't handle the pressure. I wouldn't even consider a turbo on a stock Mach 1, you would be so limited in boost, why bother?

Lots of great points in here^^^
Block good for more than you'll most likely ever make (no offense)
on a Stock mach N2O is wonderful
8lbs non intercooled
10lbs intercooled
12lbs on E85 w/ intercooled
Turbo will be fine at these same levels of boost, but far more complex to self install.
