Speed Limiters?

[V8 Killer]

What are the top speed limiters on the 3.4, 3.8 and LT1/LS1?

mines 118

i THINK 3.4 is 110... and i'm pretty sure 3.8 is 118... from what i've read on here before thats what they are.

Just out of curiosity, what about old Mustang 5.0's and the 4.6's and 3.8's?

I got mine up to 119 but I think my speedometer is off. It's a '97 RS

ALL 3.8's are 118 from the factory. I don't think the lt1/ls1's were ever limited. My brother had a 95 z28, he had his up to 155 on I-95.

I have a 125 mph speedometer on a car that tops out at 118, I dont like it. I have only taken it to 110, figured it would wrap up around 130 or so.

FWIW, it's because the tires that come with the car (assuming base package) are T rated, which means they're only safe up to 118 mph. ;)

For what its worth I have heard of z28s with 118 speed limiters. I believe it was z28s with "v6 tires" that were not Z-rated.
