569hp LB7

[Turbotug]

:blah:

 

[LB7Diesel]

This kinda makes me want to put mine on the Dyno. Damn those are good numbers!!

 

[Cobra#3747]

The rpm scale is interesting. Was the truck shut down around 2900 like it shows?

 

[malibu795]

i dont know.. look like it. dont think the dyno guy new it will rev to 4,000. from my logging.. lb7 turbo starts loosing effeciency around 2900-3000.
dyno sheet doesnt indicat that he was loosign rail pressure either...


cant wait to see what she does when she gets the HTT turbo installed and lift pumps


adam is currently out of cell tower range till some time tomorrow

Since I haven't the time to hit a track, dyno # work well for me and my uneducated friends that go holly shinikey Batman. Sounds like a good run. I hit a dyno day once with Pat's tune and no engine fan and slammed out a whopping 397 hp. Bad dyno day?

sound like a tow tune with a stock tranny

Same tune that Kat laid out 530ish RWHP with, SCIV trans. Dyno was wack IMHO. Sad thing was the fact it was a Dodge dyno day! Ran exact same setup on a dynoJet later following week, 486hp/909 tq.

hmm... probly right

The guy said that these engines start losing power from 3000 on so we shut it down there. I wasn't going to start a pissing match with him and said sure. Also on the first run using EFI to keep in 4th something happened at 3000rpm like it kicked out of overdrive and screwed up the graph. Yes I had the BiDi controls set to shut of at 4000rpm so I know it wasn't that.

 

[2wd_Sled_Puller]

Congrats guys. My highest hp to date is 352 hp. But i can still run 105 trap speeds at the track

 

[GMC_2002_Dmax]

i know that dynos are a tuning tool...

me wanting to run it on a another dyno is like cutting a 12.0 at the track then going back to double check that that is all...


i would love to see this cut 105+mph at the track

Congrats Adam,

I am going out on a limb here and going to say the dyno numbers may not be quite accurate and my reasons are only because I have a lot of dyno experience and have tuned over 150 trucks, a lot of them on dyno's the last 2+ years.

I also have hundreds of logs with very good data containing fuel pressure, timing curves, pw,boost, egt's etc to give me an idea the limits of the stock CP3/turbo in even freak LB7 trucks.............

I would like to share my dyno experience as a reference only, if your tuning does make 569/1260 then I need to get back on a dyno soon to try and figure out what I might be doing wrong........

But my own 2002 CC/SB/LB7 has dyno'd a high of only 518 RWHP on Dunbars Dynojet and just over 1000 Lbs/Ft Tq.

At that HP/TQ and pw I was running the rail psi was in the low 19K range but holding that pressure well. This is with a Socal Billet pickup, -10 AN kit line kit from Socal Diesel, twin Laing pumps and a brand new LBZ CP3 pump with modified tuning for it and 31 psi max on a stock charger with a Bank's Big Head.

That same tune with a SC-III, Co-Pilot, twin lift pumps and a mid 1.7X/60 foot time went a best of 12.66/105.X in the 1/4 mile at a close to sea level track in my truck. This seems to fall in line with KT running almost the same speed and time in the 1/4 mile with a 530 RWHP tune and no Co-Pilot.

That same tune was also run in a 2001 without a Co-Pilot but a very similiar engine/trans setup and an extended cab long bed. That truck went 12.70 with a similiar 60/ft time racing me that day with a stock but very strong LB7 CP3 pump.

Your tune should out run all three of these trucks easily at the track, in fact I would expect a 12.40 pass at 106-107 with a decent 60/ft time.

I would like to see it dyno'd on an LB7 at Westech or another Superflow dyno that has a lot of experience with these trucks to back the numbers up again as they seem a bit higher than normal especially the TQ at over 1250.

I think once it gets backed up on the dyno and track then you can take the credit without a doubt for your accomplishment.

Good Luck,

Tony

I have learned with tuning that some trucks perform way differnt then others. Tranny are the same. There is a differnce between a week 569 hp and a strong 569 hp I beilve we can pretty much say its a week 569 hp. What i mean about this claim is if u have another vehicle making the same hp with a fuel rail cp3 mods and a lift pump it will pick up alot quicker on the bottom end and level out up top.

Just like i know a transgo is not a subsitute for a built tranny. But with just tranny and stock conveter i am able to clock off 105 mph trap speeds. But my truck seems to perform better then others. with just the transgo.


I two am not calling BS because im tired of applagizeing when im wrong. But if its backed up that will be awesome.

All was aid about the corrections was that this tune was corrected to sea level. If it helps when he was setting the truck up he had to find out a number with the dyno before we could run and I think it was in the 50's.

In the last 4-5 years that the Dmax has been out I have not ever read about, nor have I ever had a dyno chart produced that had a TQ reading that high with the truck set-up you have.

I have dyno'd trucks with BD turbo's and 20% sticks that have made that HP but not anything close to that TQ.

In my opinion, you would need lift pumps, twin CP3's, a GT4094 or better like an A5K to make that much TQ wthout the use of N20.

I am only playing devil's advocate and not trying to tear your truck or Adam's tuning down in any way.

I have been following duramax performance since late 2002 and have had my hand in a lot of builds with varying combinations and IMHO the numbers just don't add up.

Feel free to discuss tech aspects of dyno'g, or comparitive tests.

Any personal insults though, will be handled the same as they would if we were all sitting around the table at Christmas dinner.

Thanks.

devils advocate... no porblem tony. this is only the 4th tune i have ever had dynod.. first was redding back in june 07 i did 450 then joshs 485 and now adams both the 530/1000 and the 569/1260 tune....
im going to see it i can get the sheets from josh's run due to i havent seen them

adam asked for a strick "dyno queen" tune.. so i built one... he loaded it right before he put it on the dyno and ran the tune..... i put "it" in another truck and diveablity was a major problem that was to be expected....

adam

? whats your opinion on the 530/1000 run? it is less of a tune than the 5691260 run...

 

[GMC_2002_Dmax]

? whats your opinion on the 530/1000 run? it is less of a tune than the 569/1260 run...

I think that 480-500/950-1000 is possible, but with the fuel required to make those numbers a lift pump is surely a requirement in my experience.

Anything is possible Adam, just that the average truck usually will need a lift pump, the freaks might get away without one......

Most likely if the rail psi is at or above 19+K you could knock on 500RWHP without a doubt, but the TQ gets trickier to make.

Keep on dynoing and tuning, efi-live is an awesome tool. It has been proven over and over again that with enough time spent anyone can make a Dmax fast.

[specialagentPK]

Tony we have had dealing in the past and I have the upmost respect for you in the Duramax community and as a person for the few times we have talked so everything you type is all personal experience and I do not take any as an attack on my truck.

Adam the 530hp tune has the driveability of a stock truck. The power is there if I need it but not there for gentle cruising.

 

[Josh2002cc]

I will post a copy of my graph that put down the 485hp/955tq with Adams' tune. The tune I ran the 485hp on, is my DD tune. It drives great, but with that said I have not driven a "big" tune with my truck since I got the trans done.

I am still attempting to make my way to the dyno here in Omaha. Not really sure when this is going to happen but I promise you all, it will. Hope this helps.

BTW: I thought the stock IHI stopped pulling around 3100-3300 rpms??
