Is the LT1 governed?, if it is what is it governed at? I have a 96 LTI stock.

No I don't think so. I had my 1993 up just above 150mph so I would not worry if I was you. Be more concerned about traffic, pedestrians, your tires, and your car.

150 MPH, thats cool. I take it you have a manual transmission? I have a auto, so probally a little slower...i guess......Tyring to find a track or strip around here somewhere to find out.........never, on public roads..

There is no governor and it SHOULD run 160-168mph somewhere in that range. You'll run over 100mph in a 1/4 mile stock

Governed only by the weight of your right foot and the size of your brain.

aboatguy

Governed by horsepower(or lack there of), traction, friction and aerodynamic drag.

Apparently it does have an RPM limiter, but not a MPH "governer".

Let me know if you find a track in the PNW where you can do top speed runs. I'm up in Seattle and starting a forced induction project on a quest for 200mph.

Yep, my '92 automatic Roadster will only pull a sustained 148.

Yes it is because there is a rev limiter. My '95 LT1 took 172 mph untill the fuel did cut off (5850 rpm). I measured with GPS-perf box. I have a stock heads and cam. Next i need more revs.

VenkmanP

Yes. In the B-body and some of the F-bodies.

SilverBeast

The "Official" GM cutoff is "above approximately 5800 RPM" (page 6-737 of the Service Manual).

Well the LT1 in my 93 6spd is good for 165 and maybe a couple more miles an hour. That was in 5th and right at the top of the rev range but before fuel cutoff...I didn't think hitting the fuel cutoff under those conditions was such a great idea. 6th gear at 165 kept me going at that speed a few more seconds but zero increase.

Under the traditional use of the term "governed"... No, the LT1 CORVETTE is not, but in stock form you aren't going to be going any faster than that.

I had 152 in my 92 auto, no idea what rpms though.

grandsport504

my 1995 lt1 6 speed will only do 155mph then it just sits there no matter how long i stay on the throttle it never passes 155 in 5th gear? it is a convertible. i done 155 runs top up and down. no change in top speed.

steve40th

Its governed at 254/255mph. So get hot and by some serious HP pieces

grandsport504

and some serious aerodynamic peices so you dont fly away.

steve40th

Get the Callaway Aero package, worked for Sledgehammer (with a little lip spoiler on rear)

all show and more go

whats an 86 corvette top at?

c4cruiser

The early D4's were good for around 150.

STL94LT1

The LT1 has a 255 mph fuel cut-off speed. But as others have stated, aero and HP will limit you long before 255 mph.
