What is the top speed with the governor disabled?
I had an 90 Daytona ES with the 2.5l and the governor would kick at 120 mph which I cold hit in 4th gear. I always wondered what the top speed would have been in 5th gear with the governor disabled.
Every thing I could find on that car as far as specs it looks like no one took it above 156 MPH. Stability problems started occurring around 125.
The Shelby version is a bit different than the ES in some aspects , it would run up to 155ish and pretty solid around 145 on a smooth flat road before you got very light in the front end. On a road with bumps / hills, keep it around 125mph. If you have any weight over 50lbs in the rear hatch, you can get a nasty suprise around 100mph. You can catch air and scare the cap out of yourself. The 15" crab wheels placed the car lower to the ground than the 16" Shelby pumpers, so this also changes things.
And your 90 should have a Turbo IV VNT 2.2L, not a 2.5L. The 2.5L is for 91 models.
