Hey I have a 2000 Trail Blazer, I was woundering if any body new what the top speed is on a stock one. Thanks Mike

 

I was told by the dealer that its around 45-50 but my guess is probably a little less...maybe 45.

My old 250 trailboss was clocked running 55mph (We had a car running beside it all the way.) and that was not in a straight stretch.

 

I had a friend that owned s T-blazer. I ran along side him with my xplorer and had him at 53. For $30 you can add a K&N air filter and up that to about 56 or 57

With my hpd pipe, jet kit, k&n filter, wiesopiston, and bored to282cc, it does 64!!! It can even keep up with my bomb, and my raptor!
