What do you have the redline set at? I think that the 3.31 gears are going to really hurt any acceleration in 5th. You should get to the top of 4th easy, but 5th won't pull much at all. With 3.55 and Whipple supercharger (and everything else pretty much stock) I was able to get to to 157 in the standing mile. I think you could hit 145, but 150 would be pushing it.

That's about wat I was thinking. I was gonna say 155 tops. Man I love my GT lol.
Got done with fireworks tonight. Took me and 2 other friends for a 6-7 mile drive on a straight. Asked me wat the top speed was. I said idk probably 145-160. Got it up to 100. Then shut it down. Just a quick sprint. They always like to see the 3 digit mark. "man this car is bad" I always like to hear that lol. Gonna keep it forever

I will assume that any speed limiter is disabled (there seems to be one that kicks in somewhere in the low 140's that doesn't much matter for a stock 4.6L GT).

It's like nothing at all with good shocks and a better wheel and tire package than the early GTs came with.
I wouldn't even think about going 120+ on any public road that wasn't closed for a special performance event (Silver State, Texas Mile, etc.).
