ready to go to the track almost?

Buick gurus you have been a big help in my preperation to go racing. One more question. I wont have time to make a few runs before a buick event comming up in a week. My car dynoed at 600 to the wheels on 22 lbs boost with 18 degrees timing. I was using 114 octane fuel. I have read where its safe up to 24 degrees with c16 and that I should make a run with 20 degrees and check plugs a/f etc. Since I wont have time for numerous runs I will run with the 22 lbs and 18 degrees for this track event. Would I be better off just using the 114 octane as I am told if I use c16 I may lose power because its slower burning with my 18 degrees of timing. The calculators say the 600 at the wheels is good for low 10s at 3650 lbs my car weights. I assumed 600 at the wheels is about 750 at the motor? Thanks

I would bump up the timing if you check you EGT's you would find them pretty high, I would set it at 22-24 also you should be able to run more the 24psi on C16.

nojug thanks. I do not have a egt I have a fast system in the car that was tuned at the dyno shop. He set the timing at 18 degrees I assume because he never asked if I had racing fuel in the car. I think he assumed I had regular pump gas in the car. I may have not been clear, my question is should I use the 114 octane with the 18 degrees or put in c16 with the 18 degrees? From what I have read so far it seems the 18 degrees will not need c16. When I have more time to tune and run the car I will use the c16 but dont want to use the c16 now if it would not do any good or maybe hurt the performance with 18 degrees. The a/f was at 11.0 with the 18 degrees and 600 rwhp on the dyno. Just want to get used to the car and be consistant this weekend not drag every last 1/10 out of it. Plus be able to drive it on the trailer at the end of the weekend
