Speedometer past 155
And to Blazen Fire, with a motor like that, you might need something past 200 depending on how its built! Have fun buddy!

I know of 2 Corvettes here with limited edition 300mph speedos. They are just show cars so it's only for looks but they have them.
I like my 6le speedo. You'll have to remove the restriction in the pcm also, i believe the limiter in the ls1's with z rated tires is 162 mph.

The fastest I've gone in the trans am is 140. The fastest I've driven a car is just shy of 200 (no 200 mph club for me), but that was in a lambo.

that looks nice.
Try taking a prius over 110. Thats an edge of your seat rush. I took my exes to about 112 and the best thing about that is those cars speedometers hold the highest achieved speed, like a GPS. So i pray that her dad one day finds that and just sighs.....

The fastest speed a stock LS1 has ever achieved without the limiter was around 180MPH, stock that means 350HP. And you think it takes 350HP more to hit 200MPH?
