Default Big tires, turbo on 6psi.

Customer picked up a kit a couple of weeks ago.
Had to build him a custom crossover, to compensate for the hi lift.

401hp / 410tq 6psi

big tires the hp killers. I wonder how much a big 33" tire adds to parasitic loss. That customer has it right though. 400 to the wheels in a lifted truck is gotta be pretty sweet

Its running 35s but I recently dropped the lift from 7.5 inch down to 5 inch.
I need to get a set of 33s now because its rubbing on turns.

Here is a fly by video:

I'd say they are in comparison to a 27 or 28" tire that most big power guys are running

Stock tires are 32"

I'm sure my 315 drag radials (30") were chewing up more power.

Quik dyno'd his truck on 35s and stockers and there was a 10 hp difference, basically nothing.
