I really appreciate all the help you guys have given me over these last few months, dunno what i'd do without it sometimes.

Special thanks to Chicago for his massive Holset and DP combination, i know he spent some time on building the DP.

The engine is in, put about 40 km's on it so far. The engine was run on a test bench before i got it so i trashed the oil filter right away, new oil cooler on also. After 10 minutes of running in the shop the second oil filter went south also. I will probably put about 200 km's on it and change the oil and filter again. Rod to the wastegate is backed right off, its loose when not running, i'm taking it easy on it but even on the hiway just giving it a little bump on the throttle boost hit 12 PSI, 60 MPH/2000 rpm seemed to have about 3 lbs of boost. I haven't set timing or TDCO yet either, its running good and is once again has an extremely loud engine rattle! While the engine was running i had the glows on the timer set for 20 or 30 seconds i think and then they do their on/off thingy for a minute or so. You should have seen the look on the mechanics face when the glows kicked out and the rattle increased 5 fold, i think he was ready to run and shut off the key. Cold the oil pressure pegged the end of the scale, 550 Kpa i think, warmed up was 275-300 or so (new hi output oil pump). I have a ton of under the hood tweaking to do such as air filter mounting, CDR, routing hoses, electical etc and also get the exhaust back together, kinda noisy with just the DP on it. Hopefully the lift kit will be in on monday or tues and i can get that done also. Anyways, input, suggestions or recommendations are always welcome.

Dyno? Yeah but not until this ones got at least 10K on it!:D

Damn man, don't you ever go to bed? lol

Hard to hear the whistle with just the DP on it, but its there once it hits about 5 PSI.

YOU ARE GONNA LOVE THE WHISTLE!!!!!!!!!! How far off is the exhaust?

I think i need to make up at least 10" to get to my 4", dunno what i'll have to do. We stretched the old DP to 3.5" and added a 3.5"x4" swage on the old system. If that DP you supplied was any longer i don't know if it would have fit without removing the exhaust manifold anyways.

I'm sure I'm going to have to take a trip back to your neck of the woods to have a peek at this beast. Congrats. I'm off to Wainwright for a week....gotta do the Canadian Soldier thing. I'm the Maint Sgt in charge of keeping the Leopard tanks running, hey how about a 34liter 830hp V10 diesel?? actually my little Toyota Diesel makes more Hp per liter than this monster. If you make it up this way I can definately give a tour of the shop and might be able to swing a drive in it. If you think a 6.5 is loud with no exhaust you got to hear/feel a tank engine being run up on the floor with no exhaust, it has no turbo's to kill the exhaust, but it is supercharged.Trust me you feel every cyl fire.
The wife drove the truck today for the first time and her only complaint was it was too high, towards the end of the drive she was warming up to the height as it gave her a better view of the road,other than that she did OK. and my sons(3.5yrs old) response was "I like this monster truck" He is definately my son!
Well I leave tomorrow morning and will be having withdraws from not being able to check my fav site. Take care all

OK guys now i would like a little help once again with the timing on this thing. After a few miles on it i decided to do the time set command, both Act/Des went to 0, smoked like crazy and ran pretty rough, ECT @ 180F+, TDCO was still -1.76 as i never changed it and suspect it would have died if i did.

I moved the pump a good 3mm to the drivers side, warmed it up again and did the time set again, now i'm getting +/- 3.5 ACT and 0 Des, so i commanded the TDCO and it went to +2.02, runs fairly rough and smoking.

So my question is do i have timing in the ball park now and only need to move the pump more to the drivers (2mm?) and then command only TDCO, NOT time set again also? ESO is pretty much straight up, maybe slightly to drivers, another 2mm and for sure it will be tilted to the drivers. Help please?

I'm not the expert on this, but I just did mine. Sounds like you need to go towards driver's side as you say.

Command TIME SET, wait about 30 seconds, then exit.

Go back to engine parameters, note displayed Des\Act values - should equal, and be around +3.5deg to meet oem spec.

If so, command TDCO LEARN, engine may stumble for a bit, note TDCO value - exit when it reads -0.5deg.

Go back to engine parameters, Des\Act should be +3.5deg, Idle rpm shold be 675-690, Fuel Rate should be 8-9mm,TDCO should be -0.5deg.

Timing may fluctuate above and below, but should average +3.5deg

Display just always goes to around 12 when out of time set, the only time i see it bounce from 3.2 to 3.5 is when time set is selected? Once out of time set and into TDCO it was 1.94 the first time and 2.02 the second time commanded.

Fuel rate was about 4-5mm but that may not be accurate with the flash for the 5068 pump.

You may need some input from Wester to get that system set up - the 3.5deg TIME SET is correct, and the -1.94 may also be correct for the 5068 tweak-up.

I would expect so see +8.5deg Des\Act Base Timing for that -1.94deg TDCO.

I have a bare 5068 camring, but have not learned much from it - only that the ramps ARE more agressive than the 5288\standard camring

westers told me before as long as TDCO was within that -0.5 to -2.0 window IIRC all would be fine, i'm just having trouble figuring out if i should move it again or not, it runs pretty rough at temp and stumbles on throttle stab too, timing may have averaged closer to 3.0 though. Your help is appreciated GMCTD. What should i do?

Back IP off to the passenger-side by 1mm, do TIME SET, exit, note Des\Act, and TDCO in engine parameter display screen.

You'll need to let it idle for a bit after exiting TIME SET, depending on how long it takes to come out of cold advance\fast idle, which will indicate +12deg or so and dropping

If it is around +8.5deg Base Time, do TDCO LEARN, look for about -1.5deg, exit, recheck engine parameter screen.

Note : the 5068 may also have the 'bump', as the low idle Fuel Rate seems to indicate, thus may result in increased calculated TDCO value for any given Base Timing value.
