dyno sheet he didn't save the last one which was 730 RWHP and 805 ft lbs torque remember this is with less than 20 miles on the truck, Low boost very safe tune

lost second gear, won't worry about that until chuck opens it up and finds out what happened

haven't run it yet, broke the level 5 4L80 the first day and a half

Yes, that is why I don't have a tranny

ain't nothing but a thing. I did get to drive it for a day and a half I knew I would be breaking things, it's the game we play. Mark

if my truck is running I will be there, would be nice to get some track time in Mark

Dave, you could always ride with me. Mark

looking like a great project. Mark

there are no clutch packs. it is the Viscous Coupling you will over work http://www.denalitrucks.com/documents/serv...-149%20view.htm

OD does make a huge difference, you will put undo wear and tear on you T-case, nothing to do with the computer, these unit are completely mechanical. but if one set of tires are a different size it will think one is loosing traction and start shifting power to the other set, which in turn would cause your transfer case to work harder. Mark

Don't be to envious, lost second gear in the Level 5 4L80, truck is back at the shop. pulling out the tranny and sending it back to find out what happened. Mark

picking up a spare transfer case just incase mine decides to take a dump on me, go to the G2G in AZ on the 22nd it is only 5 hours from LA

also no traction problems with the AWD, Said it just took off like an arrow, I pick it up tomorrow

I am going to copy and paste ricks comments and the dyno graph Ok, Ok, Ok. Everyone settle down. Ok, so here is the low down from today. I only have about 60 miles on the setup so I am keeping him on low boost for now which is about 12psi through the runs. The motor is pretty healty at a nice high ten low 11 AFR. But it does come alive when you lean her out. But thats not what I was going after. I just wanted to make sure the damn thing works. hehehe. Works it does. The graph I am posting is one of them, but not where I ended up. I wound up maxing out the dynos TQ capacity on the last few runs when I leaned it out for more power that it caused me to erase the few higher pulls. Oh well, I will have more chances later for more runs on another dyno. The Dyno maxed out because my dyno is rated at 3300ft lb divided by what ever gear ratio the chassis has. So since his truck has 4.10's in it, the dyno stopped at 810 ft lb. If the gear was different, say a 3.73, I could go alittle further with it. Not bad for low boost. Of course it kept making more as I leaned it out, but its ok. Its just a start anyways for this truck. So off the dyno to put the AWD case back in it. By the way, just in case you are wondering, I modifiied another AWD case to be a direct dyno case as a 2WD. Worked good. So here they are, just a start, I DONT WANT TO HEAR....it should have made more, or how come you didnt turn it up, or blah blah blah. IF you paid for it, you would be saying a different song. I have to make sure it all holds before we get crazy with it. So on the street, the AWD kicks so much ass. This truck hooks and goes. The boost on the dyno came full bore around 3000rpms. I tried to sized everything on this truck to act like his maggie did. I knew it would be hard to convert a maggie guy to a twin turbo guy. So I think I did a pretty good job with how the boost comes in. Its super quick, you step on it and it gets up like a bat out of hell. I didnt think it would hit that quick and my one handed driving quickly became two hands. So thats all. Simple....so far. BTW, the last graph I had before it got deleted said about 805TQ and 730+ HP.

15 degrees of timing

very early numbers with a very, very conservative tune because she has less than 100 miles on it and I am taking a trip to LA on monday which is a 700 mile round trip 12 psi 730 RWHP 800 ft lb

truck spent the day on the dyno being tuned, will have some low Boost dyno numbers tomorrow.

yes, but as soon as the back started slipping it will start transferring power to the front, up 100%

yes I will, trying to get some miles put on her before the AZ trip. here is a better video, http://deweygibson.com/Videos/2004Denaliadvertisement.wmv

probably going to pick up the T-case this Monday, not sure yet,

OK with me, might want to talk with Dave, I don't know what he has planned, also I will be spending a day or so in the LA or San Diego area on the way back, Mark

responded,

you will see it there unless I break something between Sat 16th when I pick it up and the 22nd when I get there. I took the who week off so I can drive the Truck around some, was having withdrawals, Mark
