About the supercharger modification. I'll at least point out where I thought there was the issue. The statement:

"You can never expect a 50% increase in power from just a supercharger....maybe a SC, tune, full exhaust, intake, and some cams"

Now, all of those things that are listed are power adders in and of themselves.

For instance on the list from JDMs 425 rwhp kit....

Saleen S/C
• Tuner
• Air Kit
• 90MM Mass Air
• Mass Air Harness
• 39 LB. Injectors
• 3.60 Upper Pulley
• K061080 Gates Belt
• Vaccum Line Kit
• Saleen Extreme Inlet Tube

The only thing on that list that adds power is the supercharger itself, the pulley adds more power than the base setup, but the pulley is part of the supercharger itself. None of those supporting modifications will give power to the car by themselves, with the exception of the tuner, but a tune is always needed for a supercharger going on a computerized engine. It isn't fair to seperate them because it is impossible to have one without the other, especially on the new Mustang.

You could argue that the extreme inlet tube adds more power to the package, but maybe an extra 10 rwhp at the most which would still leave the package with over 410 rwhp if you used the factory airbox.

I guess my point is that supporting modifications like fuel injectors aren't the same as saying you need a full exhaust upgrade and new cams to make over 50% power with a S/C.

I'm not trying to start stuff again, but that is how I took a look at that argument.
