I was driving today and figured I would see what everyone else has here:
55 MPH
2 PSI
700* EGT
1400 RPM


65 MPH
8 PSI
800* EGT
1750 RPM

I have 40s and went from 355 to 410 gears and Im curious what everyone elses RPMs are at those speeds to see if I need to upsize my gears more or not.

 

My 2500 runs 72 mph at 2000 rpms, about 4 psi boost, 700 pre egts on flat land. 3.54 gears and 265 tires

 

At about 65mph, 6-9 psi, 750egt, 1700rpm 36in tall tire 3.55 gears.

 

any others?

from what it sounds like I got it pretty close to stock as far as those numbers.

 

pretty much the same as infidel

 

I think I have a vacuum at 70 MPH! Dang goofy, large turbos.

I have to go past 70 to even move the needle
