I have a 95 z and was racing my friends 95 z down the highway and i had it in drive and when i hit 125 it hit limiter. was that the speed limiter or the rev limiter?

 

If you were in 4th gear it was probably the rev limiter at 5800 rpms at around 125, that sounds about right. Put it in 5th gear and keep on the gas pedal and you'll go faster guaranteed

 

Since he said he has it in "drive" I'm guessing he can't put it into 5th gear

 

If you had an A4, and it was in "drive", then it must have been a speed limiter. If your car did not come with Z rated tires from the factory, then it is limited to somewhere in the 120MPH range.

 

I had the same problem hit the speed limited at 125...took it to a shop and LT1 edit the limiter to 165...
I hit 149 the other night on a toll road (14 straight miles)

 

Yeah I guess so, I caught that after I posted, didn't feel like editing. Yeah you're right though without the Z rated tires I believe there is a speed limiter. I didn't have a speed limiter in my A4 L98 Z28....I hit 130+ a couple times in that baby. And I KNOW I don't have a speed limiter in my M6 LT1...hehe, I have a nice fat top speed. If you decide to go faster, better get the Zrated tires!

 

Thank you for the information. What is the top speed without the speed limiter? I have the 2:73 gear ratio does that mean that it did not come with the z-rated tires. Is there a reason why they put a limiter other then the tires. Is it a different rear end setup that can handle more speed. Thanks again

 

155 Mph in 5th gear with 3.42's at El Mirage Dry Lake bed. Ran out of room (it's a small lake bed) and felt the tires starting to slip at 155 (back end getting light). In 6th gear I could only get to 140mph before I ran out of "road" I plan to go back out since I've installed the SLP headers and see how it does.

 

169.26 "GPS" certified before I ran out of room. I know I can go faster, just need an longer road.

 

255mph

 

That is awsome!!!!!!!!!!!!!!!!!!!!!!! I will have to get my limiter removed!!!!!!!!!
