Surprisingly Ozzy wanted to go from a roll. I told him it would benefit me more than him due to traction, but he said he'd already broken 2 5-speed transmissions (manuals) and didn't want to risk another. He had a nearly 300 lbs passenger. It was a 3v 4.6 with an edelbrock blower at 12 psi. He did not spray, and claims it should run ~500 rwhp. Something tells me that's just an estimate. He did not powershift. I was powershifting 3-4, and I did not brake boost. My car is a turbocharged '93 GT with a T56 and 3.73s on ET Street SS tires. I ran it on low boost at 7psi on a 363 with AFR205 heads and a very streetable sub 220 intake cam, and a quick-spooling GTS76 turbo. I'd imagine it would make in excess of 500rwhp there pretty easily with even close to optimum tune, but there's really no telling how much power is left on the table without access to a dyno or a track and tuning very conservatively (16-17* total timing and 11.5:1 AFR). Initially we went 3 times from 40. This was a decent spot in 2nd gear for me. On the first race, I honked it off, and got a pretty decent jump. He missed the 2-3 shift and I ran away. 2nd race, I gave him the hit, he got out on me by a car. I missed 3rd but recovered decently quickly. He had 3 cars. In 3rd gear I stopped his pull and in 4th, I made up 2 cars and starting to pass when we had to let out for traffic. 3rd race was pretty good for both of us. Again, I gave him the hit. He hopped out about a 1/2 - 3/4 car while my turbo spooled, then I granny shifted to 3rd to ensure I wouldn't miss again, and pulled about a car. Shifted to 4th and put a couple more cars on him. We pulled over and talked. We both had a lot of fun, and agreed that my car was stronger but that the races were pretty close. I asked him if he wanted me to take his passenger, a mutual friend, and go for another run or two. He agreed and wanted to go from a 70 roll. Starting in 3rd for both of these runs made it nice because 70 is a pretty good spot between 4k - 4500 RPM, I'd say. The turbo spooled quickly, and the powershift is easy. With ~300 lbs less in his car and that much more in mine, I expected to lose these races, but I guess the quickness spooling made enough difference. Both of these races were fender to fender in 3rd. He was shifting at 6, and since I had a few hundred more RPM to go and wasn't granny-shifting, I nosed out before the power-shift into 4th and pulled ever so slightly until letting out with his bumper at my door. It was the best race of the day. We pulled over, chatted it out again, complimented each other on the rides, and swapped the passenger back over to his car before going our separate ways. I was absolutely thrilled at the results. Ozzy told me that car had been neck and neck with a hellcat and a ZL1. Is 500rwhp really feasible for that blower at 12 psi? Is that much power really going to make an S197 run that close to a ZL1 and Hellcat? Regardless, I was really happy with my car. Keep in mind that I have a conservative base timing table that has never been tuned and was on the lowest boost setting of ~7psi. It might take quite a bit more timing. This car is entirely self-tuned! So to have it perform well in action was just a blast!
