yeah, its one I created myself to judge different RPMs back when I had my first Challenger and wanted to upgrade rear-ends, so it’s saved in my Google Drive account and shared out. I’ll just send youthe link and you should be able to open it and save it locally to use for different inputs.Also is there any way I could get that calculator spreadsheet? I’d like to compare the 3:06, 3:73 & 3:91
Gas mileage is all that will be hurt, probably lose a couple three MPGs over what you get on highway nowWell in all honesty I just drive locally 95% of the time. But I do like the comfort of knowing it could still be drove on a vacation or road trip if needed.
If it turns 2,500 rpm’s at 70mph I don’t figure that’d hurt anything on a road trip.
