I went to the dyno to meet up with Chris and Laura in Boston and the dyno was closed so I couldn't dyno my car. Since the dyno was closed Kevin from Primespeed decided that we go to the track instead. I went to the track late at night, swaped wheels and tires to some BF Drag tires and stock rear wheels. I let Kevin drive my car at the track. He did a very nice burnout and when he went to stage and launch, the NA differential blew :) Didn't even get one pass on the car. The guys at Primespeed had a big smile on their face because they now know my car has lots of power :) I am swapping my stock rear end back on and I am hoping to go dyno the car and race it next week. Lets just say it runs real nice at 1.8 bar LOL!! Primespeed made my Z a real monster!! We checked the plugs after we ran 28psi and they were perfect. No detonation whatsoever. I spent the whole day with Kevin and not to sound gay, but he is a very cool and down to earth guy. He tried 110% to get my car running perfect and he knew what I was going through because it has happened to him and his brother with their high hp cars. Did I meantion my car runs strong at 28psi? LOL:)
