LAst friday night at the track got a chance to run a C5Z with nothing but cat back exhuast and tune. I got major sideways got out of it and back in and still spanked him. You will see in video.
2010 Challenger R/T at track also. He had exhaust cutouts and said he was spraying 125 shot. He would never pop his hood to even cool down. So don't know if he was just being cool or what. But he got his ass spanked by me and a LT1 383 Fbody running a procharger on 12lbs boost. I tried run the Fbody but he blew it up at the track. Z06 was his also.
Next at the mustang cruise Saturday is a 09 GT500 with stage 3 ported blower, 2.5 pulley(18lbs boost), full exhaust, DR's. All runs was from 50-125/130 minus 2nd we tried a 35 roll. I don't think I did to bad even though I lost. He was very suprised by how well I did. He even offered to give me rematch when I get stall and tune for E85. He said he had it street tuned and never on dyno or track. But said it should be close to 700whp. I am arbout 645whp right now. 2nd race i tried shifting to 1st to start in higher rpms. It stayed in 2nd even thought 1st was selected and I redline when thought was shifting in 2nd..it needed to be switched to 3rd.
