Hey,
If you have/had a 99' GT and you wanted to supercharge it, would you go with 8 or 10 psi???

I've heard that if everything else is stock, then you should probably go with no more than 8psi. Possible damage could ensue otherwise. I have no data to back this up, so I may just be smoking some bad crack.

:s3 I have heard about 8psi being the safest... but, I will modify the engine more later...

How much do you think I would have to spend to run 12's?? Just a supercharger won't get me there...:s2: I have a list of things, but I want to know what you think.

Not entirely sure. Generally speaking, parts are cheap. It's the labor that's expensive. I've found some 3.73 gears for $150, but people want 400+ to install them.

I'm in no way an expert on the mustang. I know there are a lot of things that can be done to decrease track times. I'm sure you've researched a lot of them. Personally, I like to go one mod at a time and get used to it using the butt-o-meter, and the 3.73's are my next thing.

that all depends wade.

my cobra is good for low 13's right out of the box. i slap some 3.73's or a supercharger at 8-10psi and i should be in the mid 12's. :s5

I think the 99 GTs ran somewhere around 14.1 stock...
