Message For me it is hard to determine my desired static compression for use with e85 or e100... Considering the variable octane rating and dynamic comp ratio/temps change with different turbos.

At 8.5:1 compression and a quick estimate assuming a bunch of stuff I should be able to get there at 40psi @sealevel with two Garrett 3076. That is staying below 8000RPM.

I'd be down to go to 9:1 or 9.5:1 and maybe get away with converting my gt2560s to 2871s/billet milled 11blade comp wheel. Would spool quicker but at 48lbs/min a piece I'm not sure I'd I would be able to break 1000whp. I want to be able to throw my turbos in a peak efficiency range and still be able to run good amounts of timing advance.

Do you have a suggestion for doing the calculations? Also bsfc for this motor?
