Hi,

I tried googling this and can't find any information.

Does anyone know the top speed of a 1989 Corvette Coupe, stock? Or any C4 Corvette with the L98 engine?

Thanks

This has been a topic just a few times in the past... no one really agrees but I hit 155 and was still pulling hard. I doubt an auto is quite as fast as my 6 speed. People also say it tops in 5th gear but I loose power and can't accel after about 145. I shift to 6th and im at like 3k rpm and start pulling again. I've been told that 6th is not meant to put power down and can cause damage pushing it.

All in all I think 165 is a safe bet in a lightly modded (exhaust, air box, maybe mild porting) and a 6 speed trans, stock gearing. I think my auto 87 would hit 150 and that was it. It had the sport gearing though so top out wasn't as good.

These cars are better at lower speeds though, where we can utilize torque.

Rock stock between 150 and 155 depending on the rear, trans and weather.

We had a member he claimed his 87 Vette would do 200 MPH. He is no longer active in this Forum.

New,

depends now on how hard it's been driven.

But you will need a lot of room to get there, and don't even think of trying it on a public highway....

You don't have to drive fast. It is a Corvette. Any DD now will be faster than a 53 Vette.

86 auto 144 at 4500 rpms thats tops.

I have read claims via old magazine articles that when the 85 Vette came out, it was a 150 MPH car. With the Nash OD at .64:1 and the torque curve, I believe it.

Damn Friz, how much will he need?

Good info! Thanks All!

If you go by the speedometer, like we did in 5th grade, the digital goes to 999!

Well, by way of comparison, if you started off in San Bernadino......about halfway to Victorville, but there's a climb involved there. Bad example. If you were going east from Banning, about halfway to.....uh......Hemet.

I can attest to that. I live in Hemet, and that's about a 20 mile run. You'd need every bit of that 20 miles

PLRX

I guess it needs the Hemet Hwy 79 down hill road. There is an apple orchard right at the bottom next to the Crocodile Nest Bar.

I got my 85 L98 to 155 MPH once

My grandpa lives in Hemet.... interesting town.......

The best spot I've discovered is I-10 between Phoenix and LA. HUGE long streches. Mostly 18 wheelers in the right lane that that's about all the traffic you'll get during the week. The air is also pretty fresh and If you get it on a nice 80* day it seems perfect.....

But I have NEVER gone above the speed limit in my car......
