Mine is 11.2 pounds. Stock was almost 19. The holes are for attachment of the steel insert.
Mine launches just as it did before. But the car only weighs 3080 with me in it. It ran 8.30's 1/8th with 60 foots in the 1.80's on true radials. I only make 287 hp. That was with the stock flywheel. And weight then was 3127. I have added weld wheels and light hood.
I'll know in a couple of weeks when I get a decent track run. So far I know it is easier to shift on hard demand, easier to hit the rev limiter also. I have to learn to shift sooner.
Ive been told you free up 2.87 hp per pound. I have not verified this with dyno results yet.
