I took my bolt on zr1 to the track last night. I was fighting my stock clutch all night but even given that the car still did great IMO!
Mods:
-Aftermarket airfilter inside stock cold air box
-Ported throttle body
-Ported snout
-Ported blower
-Pulley (13lbs vs 9lbs stock)
-Injectors
-Headers
-Tuned on e85
Car makes roughly 660/660 to the tire. I had a full tank of gas and was on my 19" NT05R's. My first two passes I got into it really easy and went back to back 10.90's@137mph (2.0 60'). I could not believe it was running these times without me pushing it at all. As the night went on I tried a few different things (shout out to Jeremy Formato my builder/tuner for track support, and shout out to Will Dugas for texting back and fourth all night helping me out with advice on my clutch/launch/ect). After letting it cool for 45 mins I got back in line and busted out a 10.68@139mph (1.9 60') then hot lapped it and went 10.58@139mph. Clutch issues were getting bad at this point but I kept letting it cool then playing with it more with the launch and slipping it. Ended up going two passes in the 10.40's and also got into the 6's in the 1/8th for the first time. Overall the night was awesome, other than my clutch fighting me the whole time I had a blast and am very happy for my first time out with the car, and to be trapping 137-139 all night. I think if I can get the clutch to hold on the launch I can do a 10.20-10.30 the way it sits right now then it will be time for more power and a clutch! I want to get this thing in the 9's!
