how fast can a grand prix gt go without the speed limiter (top speed)

[SyntheticShield]

A friend of ours has had his Grand Prix up to 155. We had our old Grand Prix up to 134, and my 442 I had her up to 130. The Cutlass has been up to 143 with a different motor in it.

Talk about a woman that moves fast, WOW!!!

I was under the impression that the cars were gear limited to about 153ish.

How do you figure that? What if your shift points are 6700? What about 4th gear? I have heard of guys going well over 165 though it takes a LONG stretch to get to! Our old 95/L67 car would shift into 4th at around 5500 rpm and that was in the 135ish range.

Highest I got mine up to was about 145mph I think. Stock 2.93's & 6300rpm shifts.

I had mine going at 152mph on a nice straight away.

It took a bit of time to get there once I hit 140mph she
started to slow down, but kept climbin.
