Could someone that installed the Jackson Racing supercharger tell me what their top speed is.

I lifted at aout 143 mph. Probably would hit 150... You'd need a really long road though.

Hell, I hit 139-140 bone stock with no incline/decline. The drag coefficient is this car is pretty bad in comparison to many other 'sporty' cars, so it takes hella HP after a certain speed to get going any faster.

I too hit 140 on I-5 and the intake sounded like a horn. The car is actually pretty stable at high speeds.
I dunno man...if you go any faster than that, you should make sure you have something other than the stock tires. They're good and all, but they are not exactly z-rated. Popping a tire at those speeds on US highways is signing your death warrant.

Stock, with AEM short ram and FC UDP I hit 144 mph for more than 5 minutes continously at permanently full throttle(223 km/h) and the car didn't hesitate a bit in control matters. I have Z rated tires.

That was at sea level on a preety straight highway in a mexican coast. The car doesn't have the hp to go one more mph up.

Another thing, watch out the oil temperature gauge at those speeds and continous WOT conditions. It got REAAALLLLYYY and dangerously hot, and that shoudn't happen.

There was a post somewhere saying that temp gauge is not a reading of actual oil temp. The thing to watch is the water temp.
