How fast is a turbo grand prix with the 120 governer removed ?????
how do you remove it?

shift it into drive instead of overdrive I think.

Yea that doesnt sound like a good idea, overdrives a really weak gear...

I think it was 128 rev limited 3rd gear...and if you part throttle it to where it stays in OD, I think Jeff got to around 153 or so? Not sure, I don't even dare 95 in mine, so I can't tell ya....I have no rev limiter so who knows I what I would get?

120, 125, or 128. I do not have my stock .bin file to confirm.

Not a wise idea to try to do a top speed run in OverDrive. When you come to a stop you might end up with the same fate as others....having Reverse and 1st gears locked together.

I'm picturing the valence flopping around violently in the wind and no center strap to hold it secure. ummm... I think I would okie foam the back side of it first and center strap it. then you might stand a chance.

GangstGP · July 20, 2006, 02:19:55 PM

So what is that?? About 135mph??

Invasion1 · July 20, 2006, 04:48:14 PM

ya about that Herb

i could push it more but RPM's were pretty high and don't wanna blow the engine at 5000 RPM's on a pushrod

TGPilot · July 20, 2006, 09:46:27 PM

I have seen 148 on my HUD and GPS with the 5-speed. ;)

mfewtrail · July 23, 2006, 12:35:48 AM

There were guys years ago claiming to have hit 150mph. I believe they had the TGP's with the earliest version of the 4T60HD transaxle that would allow 4th gear @ WOT though.

kuntzie · July 23, 2006, 07:24:06 AM

ive gotten my HUD in metric to hit 27 KMPH........ thats it maxing out at 199 and starting over..... so 226 KM/h is the fastest i got mine, and thats not maxed out either
