I'm still trying to understand the performance powerband and ideal crusing speed of the LS376 or LS7 engines.
Has anyone done an analysis to determine the optimal transaxle gear-ratios for a Griffin 960SS transaxle living behind a General Motors LS376/480 (redline 6,600 rpm) or LS7 (redline 7,000 rpm) engines?
This would be in mostly street-driven Superlite SL-C (maybe 4-5 track type events per year). Assume rear tires are 325/30ZR19 for the sake of argument.
I think the Ricardo uses a 2.611 1st, 0.625 6th, and 3.36 final drive).
I think the '13 Corvette and ZO6 trasmissions use a 2.66 1st, 0.5 6th, and 3.42 final drive.
Of the two standard Griffin 960ss options, I think the one with 2.411 1st, 0.513 6th, and 3.73 final drive would be the better of the two choices (instead of the version with 2.625 1st, 0.553 6th, 3.73 final drive). I know their website also shows some other variations...enough to make my head hurt.
