My LLY with 1500 miles dynoed stock at 256.9 RwHp and 443.9 Torque. These were from a DynoJet model 248C back in Febuary at the LA dyno event.

all i want to know is a coment was made about the lly not being able to produce the power of a lb7. so if you cant mod this new engine to the extent of the lb7 why did they replace them?

Oh just hang in there, it takes time for the mods and I am sure they will be worth the wait.

That's easy to answer; EPA


New diesel emission requirements that were effective 01-01-04 required the new engines not only from GM, but F**d and Dodge as well. That's why the 6.0 PSD, the 600 Cummins and the LLY...http://www.dieselplace.com/forum/smileys/Geek.gif

I have a boost gauge, on my LLY,cc,4x4,allison, the flucuation in the hp curve,must be do to the fact that the boost changes for each gear. some gears have less boost then the others.I am just comparing to the hp curve on the dyno report.

Well Bernie, don't keep us in the dark, what is the psi in each gear.





The dyno runs are locked in 4th gear (higher hp gear).


It could be the variable vanes moving since this was an accel dyno.


Kennedy will have a good load test ##.


I hope they were able to run the edge and quad on the same LLY yesterday.

just off the top of my head, I remember 20psi 1st gear, 22psi 2nd,22psi 3rd, 20psi 4th, maybe 20psi 5th I will try to check it again

did any of you guys read the first post link? Some pretty cool stuff there, I guess I should say interesting.

i find it interesting that that LLY which makes 590 ft lbs of tq (a gain of about 70 ft lbs right?) makes barely more than an LB7 stock. our stock LB7 make 425-430 rwtq on a dynojet.

in 4th gear where you are supposed to dyno, the low boost in 1/5 gear shouldnt matter right? this seems very disappointing to me.

246rwhp on a Dynojet.


torque numbers were unreliable.
