Is there a difference in performance from the 90 to the 91 model? - ZR-1 Net Registry Forums

I know there are slight differences in the front fascia but how about performance?

Some people say that some of the 90s cam timing out of the factory were a little more aggressive than the other years.....I know the car got a little heavier as the years went on....

When they tested the 91 in the 1/4 mile it ran a disappointing 13.8 I believe...They attributed this to hot engine temps and maybe a slipping clutch..

Top end speed I believe was still high...

Just curious....
