Hey guess just changed my set up this year. Now running a Turbo 400 with 3.73 gears in back. DO i have enough gear for the 1/4 with 26in tires or do i have to use my 28's. Will be pushing something like 400 hp with 450 ft/lbs if this helps. No weight reduction to car!

 

what rpm do you run??

 

rev limit delete with pcmforless tune. I do have MSD rev limit chips for 6000rpm and 7000rpms. I currently am using 6000 in 6al msd box

 

What mph?

I guess you will be fine

 

1 : 1 is still 1:1 in third gear (assuming you used third gear) right? You should be fine, but I'd run the 28" tire, its less prone to slippage due to its increased run-out over the 26" diameter tire.
