Have an appointment tomorrow afternoon at 2:00. Any guesses, or tips. I have never been on a chassis dyno before. I plan on running 15psi, 3rd gear unlocked, 2wd. It is an AWD dyno, but Im going to see if I can run in 2wd. Got ahold of Dave at Yank converters, and he said it's hard on the converter to go WOT locked so Im probly going to leave it unlocked. Im not out to set any HP records or anything I just want a good baseline. Combo is

-03 1500 Rc, 4x4
-Trick Front Mount, W/C, BB, T76.68AR @15 PSI
-6.0l, with 4L80E, SC yank 3400.
-STOCK48, spec, ISKY, 212/212,.530'', 114.
-Isky valve springs, stock rockers & ret.
-Stock MAFS, with screen, stock intake, and TB
-3'' magnaflow
-Nelson tune/ tweeked a little by me.(HP tuners)
-Elevation at dyno is 6100'

 

Good luck. Anxious to see the results.

 

Can't wait to see what you put down.

 

I'd say 450 at the wheels. You need an S/Dtune! Good Luck!

 

I think 450 is too low, you should at least have 550.

 

Good Luck!

 

Will the altitude hurt his numbers or help them?? or neither?

 

It will hurt his #s.

 

500+ would be my thoughts.

 

I know the altitude is going to hurt big. Don't know how much RW HP it takes but the truck is trapping around 120MPH up hear @ stock weight. What does that take?
