Apparently some people thought Tony ripped off a "major brand" tuner to make his tune. They could see it on the dyno sheets.

Not the case. I found him out!

If you go to Diesel Power Magazine, PG 142 and 144, you will see Tony's "dirty little secret" :eek:

HE COPIED MY TRUCK!!!:mad:

Trippin's Moonshine curve looks just like my Triple Stack of Doom curve all the way across! Censored

Apparently Tony watched hundreds of videos of my truck racing, read all my threads, and reverse engineered my LLY tune and just copied it over to LB7's. OR... Perhaps he is putting LLY ECM's in LB7's!!!! The NERVE of that guy!!

OK, seriously... The displacement and cam and turbo put up limits in these engines all the way down. Any tune that is optimized approaches the same shape curve and the same HP. Even LLY's and probably LBZ's eventually. It did surprise me how similiar the LB7 was to the LLY though.

So does that mean in the future a 0.4Hp and 2ft-lb difference is a win :rolleyes:

His stil is flowing liquid gold !!!!!! with HP and Torque;) ):h

Interesting statement. Exploring this could lead twards a positive and informational discussion.

Hmmm... uh... YEAH!! That was my intention all along! :D

Seriously it was. We played on the dyno a bit to get the max power at WOT on the LLY. We may not have hit the limit, but I believe we are reasonably close. I'll be surprised if the shape changes significantly.

And then when we look at an optimized LB7 tune, it's very similiar in shape and in this case, magnitude. Only Dmax Doug's curve was a bunch different (on #2, not in magazine). It goes high in the mid-range, then falls. The Moonshine LB7 Tune bears a closer resemblance to a PPE LLY stack than it does to "another" tune. But obviously Tony isn't copying a LLY stack.

So why would they be so similiar? Only time and tuning will really tell, but my edumacated guess is that it's characteristic of the stock Dmax engine.

This thread just made my day!!!

What does a stock dyno plot look like? Ever lay one of them next to the others? ;)

Stock for stock, they could look much different. Once you hit programming limits of the motor, the graphs will begin to look the same. Ex....same cam, stroke, bore, pistons, etc....should produce similar results once it is pushed to the max. The biggest difference between the LLY and LB7 will be the drive psi's because of the different turbos at WOT, but I'm not sure anyone has compared the two in that respect. I'd like to see the difference in drive PSI created between a BD and the stock IHI on an LB7.

I need to go to AA cause i can't get off the shine:D . dave

I don't know how you figured it out........I really have E.S.P. and read the ECM's mind.........it told me how to fuel the tune and write the timing curve........in fact after I put my tinfoil hat on everything became clear........

The voices kept saying walk towards the black smoke..........it will be alright.........:cool:

At least someone figured out my secret...........:eek:

IIRC correctly Dmax Doug's "last" run was where he shut off the propane and the Nitrous...................

IIRC correctly Dmax Doug's "last" run was where he shut off the propane and the Nitrous...................You got it backward Guy - #2 only run was first, then NOS/propane second. I didn't do a 3rd run as I was still recovering from watching the 687 pass.

Doug

Did you ever recover? :D

Did you ever recover? :DI thought I'd hurt something in the motor; it turned out to be the water pump going South. As for me, I don't think I'll run that combo again, as I don't want to put the plumbing through that again (mine or the truck's). :eek:

The biggest difference between the lly and lb7 are the heads and injectors. IMHO the LLY is at an advantage in the long run because the heads are a better design, with better flow characteristics than the lb7. It has been said that the lly nozzles have the same size injection orifices in them as the lb7 but when firing the injector for the same amount of time on both engines the lly will hold rail pressure and the lb7 will drop rail. These are only things I have experienced with the few trucks I have tooled with.

IMHO, I believe that if both engines supplied the same amount of fuel, then the lly would produce more low end torque and top end HP.
