took the yukon with my turbo kit, s300 60mm turbo, front mount, went to the arm drop race in kentucky, towed my enclosed, pulled the hills in 3rd gear at 2800 rpm at 50-60mph on 5.5 psi of boost, these hills were 6-8% grades and 2-5 miles long. car handles it perfectly with the distibution hitch and sway control. plenty of power too,

transmission got up to 208* at the top of the big hill on 23 leaving kentucky. most of the time the trans was at 175*, i have two rv coolers on it from autozone.

 

Was the converter locked in 3rd?

7600 is quite a good bit for that gas burner to pull that kinda hill.. and made it

 

yea it would lock in 3rd and then i even rolled in it when it got real steep and the converter unlocked, pulled unlocked for about 2 miles at 3k rpm and 60mph.

4l60e trans too

 

yea that trans temp isnt bad considering it was unlocked then

 

yep, bone stock 5.3 with a 60mm turbo, im thinking of putting a better flowing exhaust on it but i dont want any more sound.

 

your brave!! lol

 

What did the IATs get up to?

 

i saw 111* pulling the hill, the thing in the transcoolers are infront of the intercooler, im going to move those next week and throw a nice fan on them. i also have an alky kit but didnt run it on the way home. i kept the timing low around 9*s and let it rip up the hill.

 

yea thats not a whole lot of timing at all!!
i was running ~16* on 6psi and it pulled the vanbody great thru the hills from here to kentucky. but it wasnt 7600# ha..
