HOLSTEIN Posted May 15, 2005 Author Report Share Posted May 15, 2005 ha ha, really i was thinking a high of 135-140 mph would not be hard to hit as long as the truck seemed stable at such high speeds.... Link to comment Share on other sites More sharing options...
tonman316 Posted May 15, 2005 Report Share Posted May 15, 2005 don't know about u guys but i've buried the needle 120+ Link to comment Share on other sites More sharing options...

TimB Posted May 15, 2005 Report Share Posted May 15, 2005 I've been 120+ many times. Link to comment Share on other sites More sharing options...
superman Posted May 15, 2005 Report Share Posted May 15, 2005 I have been over 120 many times. Once i was doing around 120 and hit some dips in the road and it felt out of control. to heavy i guess. Link to comment Share on other sites More sharing options...
Woffski Posted May 15, 2005 Report Share Posted May 15, 2005 Not much more than 120, cause it automatically slows. Unless you over ride the stock system. Link to comment Share on other sites More sharing options...
zippy Posted May 15, 2005 Report Share Posted May 15, 2005 i've been in a couple of them past 130. one of our members hit around 140 racing a subaru on the way to the track. of course these trucks had a slight whine under wide open. Link to comment Share on other sites More sharing options...
PewterC3 Posted May 15, 2005 Report Share Posted May 15, 2005 I've had my C3 up to 5400rpm in 3rd before I had to let off for upcoming traffic....that equates to 135mph and it was still climbing. same tranny and AWD but my C3 has a 325hp LQ4 and 3.73's, instead of a 345hp LQ9 and 4.10's.

Dylan06SS Posted May 15, 2005 Report Share Posted May 15, 2005 It seems to get past 120 pretty easy w/ the limiter removed... Link to comment Share on other sites More sharing options...
BenKey Posted May 15, 2005 Report Share Posted May 15, 2005 It's just a guess above 120 anway, unless you have another speedo, logging at the time, or able to look over at the guy you're racing. Link to comment Share on other sites More sharing options...
zippy Posted May 15, 2005 Report Share Posted May 15, 2005 i have a few logged runs showing 130+. the 140 estimate was with him slightly pulling from the subaru which was doing 138 (140 speed in the wrx). we talked to the wrx owner when we got to the track.

trickmob Posted May 15, 2005 Report Share Posted May 15, 2005 I had my top speed limiter changed with a custom tune but I hit a second limiter on the high way at about 130. Link to comment Share on other sites More sharing options...
Big O Posted May 15, 2005 Report Share Posted May 15, 2005 With my governer removed and high octane fuel I once drove 95 past someone on a 2 lane highway. Pretty wild huh? I save the speed driving for the camaro. Although the Silverado SS glides very nicely down the road at those speeds ... and actually I think I got better mpg at 90 mph for the 1.5 hrs that I drove home from a seminar ...
