No conclusive data but my BUTT. Of course there are calculators out there to get an estimate

Punching in my Flywheel hp at 190. A guess on my part going by others with Gruppe-S UEL and 93 octane OFT tune. could be a little more or less but its just a simulation
Punch in 2774 lbs = 0-60 6.244 seconds
Punch in 2500 lbs = 0-60 5.775 seconds
This is just for fun im not claiming these numbers at all
Also get to drive my Corvette on alternate days and guess what, many days I just like the 86 better it just feels quicker and livelier with the power and weight reduction mods
