so i dynoed the big beast last night. 107K miles, 100% stock on 87 octain gas. 235 whp and 311wtq... revve limitor kicked in a 4500-4600rpms.

Ok numbers i guess but i find the tq a little strange. that puts me at loosing 85 hp 320crank -235wheel, 144tq - 455crank -311 wheels,

Does that seem normal? that would give like a 32% drive train loss on tq and 27% on hp..

 

not bad.....what did you expect?

 

Its got 100,000 miles on it. Id say that pretty good.

 

Im not upset.. actully had no clue what it would do.. Now i need to get the torque management, and drive line protection turned off and see what happens.

 

4l80 will take most of the loss into affect. Nice numbers anyways.

 

hmm, I'm taking my truck and one of my parents vehicles to a dyno day on sunday. One of theirs that I had considered was my dad's 8.1L Suburban. His was rated at 340hp. I would hope that it would put down more than that.

 

I am about to dyno my 2001 8.1L 2500 4x4 with the Allison transmission. I am going to do a before and after. Before will be bone stock, after will be bone stock + HP Tuners, all I'm gonna do is turn the torque management etc..off and play with the WOT timing and fuel, I figure it will gain at least 20-30 hp and tq at the wheels.

 

my sister is borrowing Dad's suburban to move this week, so I wasn't able to dyno it.
