Hey guys. I recently purchased a used Stage 6 Steggy. It will be going on a built Teksid with a compression ratio 8.9:1 (stock head gaskets) and 98 Cobra cams that will be running primarily on 91 octane but will also have a tune for E85. My question is, I have a 4# lower and the blower came with a 2.76 BF. I have been told to run a 2.93 with 91 on a conservative tune to avoid pre-detonation, and then go to a 2.76 when running the E85 tune. Anyone have input or insight on what type of power I’d be making and if 2.76 would be that much different than a 2.93? The thumbnail is of a buddy’s car using Eaton swap brackets that I will be using as well.
Thanks
Thanks
