How obtainable is 700+ hp from a LB7? I see guys running in the 11's and 12's in the 1/4 mile. Which products would best suit this application. I understand that the tuning, exhaust, intake are the way to 500 hp but what can be used for the extra punch. NOS, injectors, Propane, Water/methenol injection, drive line upgrades? Ultimatly I would need to reach the larger figures for just a few 1/4 mile runs and then we can tune it down to a safer 500 hp figure.

Thanks for the help!

Talk with Super Diesel, he's been capable of almost 800 HP with bolt on's. He loves to help others make power too.

Great, thanks for the help. How do I contact Super Diesel.

Thanks again!

Trans, Xtreme, propane, watermeth, liftpump, exhaust, nitrous, big brass balls......I think thats about it.

Just shoot him a PM. He's a Vendor here on the site.

You could do a search for Super Diesel

You don't need propane and water meth to get there. Programming, injectors and a good nitrous setup will hit 700 no problem.

I agree with that, except the injectors part. Don't feel like injecting fuel at 10,000 psi when the computer is commanding 25,000. Propane is another fuel that can take the place of injectors and it's much cheaper. Just my .02

800 hp!!:eek: I guess that removes any doubts about the strength of D'max rods and lower end.

At least you can agree that one needs some big hairy coconuts or be 1/2 crazy to want 700hp right Brandon?;)

So what kinda 1/4 times do you want or do you just want big Dyno numbers? If you want big dyno numbers might as well throw all that stuff on there and not drop the big $$$ for injectors especially since if you are running N2O most people will be bellyaching that "your run was on drugs" and "such and such did it on just #2":rolleyes: You might as well really lay down some stoopid numbers if your going to have to put up will all that crap. "Oh it was a load cell, It wasnt a load cell, the correction factor was off, you were at a high elevation, you were at a low elevation:blahblah:........." Dyno numbers, especially big ones, bring all kindsa people outa the wood work.

You will lose power IMO with injectors if you arnt on spray or have a bigger turbo. So when you turn it down for the street you have a setup that cost a lot more $$$ and isnt making you anymore power untill you add more air(turbo or nitrous) Thats why I vote for propane. When you start throwing all that stuff together and adding all those tuning factors you start running on the ragged edge and may blow some sh!t the fCensored up. Be ready to pay if you want to play. I'd also recomend against head studs......its cheaper to replace gaskets than hard parts:lol:

Didn't someone run 700HP with just a Quad/Edge stack on #2 only.


:stirthepo

The truck is an H1 Hummer that we have converted to the LB7 and selectable 2wd/4wd. On a typicall hummer you have parasitic loss around 40%. In the 2wd we should be at about 25%. A fair amount more then the typicall duramax pick up truck. We were originally looking for about 760 hp for an estimated 13 second 1/4 mile time. I really just need this power for a few runs for the film crews. So yes, my main focus would be 1/4 mile times and not dyno numbers. What are your thoughts?

Thanks again guys

look at a large stack for your best hp numbers on number 2, then add lp and nitrous, like a .090 jet sise and you will be at the numbers your requesting, keep in mind you will need a serious tranny upgrade as well

I agree with that, except the injectors part. Don't feel like injecting fuel at 10,000 psi when the computer is commanding 25,000. Propane is another fuel that can take the place of injectors and it's much cheaper. Just my .02

My rail pressure is fine with the bigger injectors but then again my CP3 may be an overachiever. :D

I just have never been a big propane fan......

Ya forgot "it's a 2WD pusswagon" in your above list! :D ;)

I think the 4l80 is going to blow its guts if you use it.....

Also think you have a cool project in the works

Money dosnt sound like an issue. I vote for a TTS Xtreme, lotsa N2O and some water meth and propane. Then you can just run the Xtreme and still have a nice toy when you yank the other crap. Throw an intake like an AFE or something and some custom 5" exhaust for cool factor.

PM Steve Cole at here, He goes by Diesel Tech for the TTS stuff

PM Super Diesel for the water meth and N2O stuff.

Mike L. Can get you set up with your trans stuff

3 stop shopping for stooopid power!

Also have no idea how the factory fuel system is set up on a hummer. You will need a pusher pump of some sort though.

Also traction in 2wd will be a problem. Most 4x4 guys here use 4wheel drive and launch in it and run it all the way down the track. Really helps the 60's

i just thought he was doing it for a few runs, be a lttle hard to get rid of the extreme afer he was done, with the vin lock

He said he was going to do a few runs and wanted 500HP for daily driving. The Xtreme is a perfect daily driver IMO. Especially since its switchable on the fly if he gets into rain or nasty weather he can just turn it down......but yeah.....I see someone doing a transplant of a 700+ HP duramax into a custom H1 as being a penny pincher and worried about eating a 1200$ program if he decided after all that work he wanted to drive a stock powered duramax:rolleyes: Noooo.....wait....I got it.....he might want to take his truck in for warantee work and then its hard to take the ECM off compared to other options:rolleyes:

Just come out and say you dont like Steve Cole on a personal level and to not buy the program becasue in your oppinion he is a **** or what ever. Why take small pot shots against his product that have no bearing on what the guy wants to do? Why not make cracks about the wait and the fact it cost 1295$ and you have to score another ECM if you want to go back to stock?

At least you can agree that one needs some big hairy coconuts or be 1/2 crazy to want 700hp right Brandon?;)

:lol: That's hilarious Philip!:muahaha: :ro)

By the way, I should have a 700+ dyno sheet for you in about a month:eek: ):h

Ouch

The tranny is going to be the Allison 1000. What do you recomend for the tranny build up?

Thanks again guys!

quad/edge is better then that controversy stirring TTS crap it makes dmax owners hate each other

look at the ats or suncoast for now, dtt is comming out with some good stuff soon as well, looking at 5k or so for the good ones

rat, i never seen his post on the 500daily driver

:joke: sort of, but definatly stirring the pot

Hey Greg, I dunno about you but I'd rather do a Powerstroke swap myself...


http://www.dieselplace.com/forum/images/smilies/muahaha.gif

powerstrokes blow up around 450hp

Now THAT would be stirring the pot Jason!!!:lol: :eek: :funnypost

Yeah if you like windowed blocks!!! tons0torque.........can't be refering to a Powerjoke!!!

When all you guy's talkin' smack put down more power, or faster times(at my wieght) than me, with YOUR truck, you can make all the jokes you want!!:eek: ):h :muahaha: :blahblah: :D

you should change your name to tonsof0torque

How much torque you got there bigd:confused: ;)

I thought your race weight is 5600 lbs though?

Am I wrong?

Got Juice?,

Look in the sig;)

7900 lbs:eek:

You are thinking of David Lott. I have a REAL truck!! (Sorry David!! LOL!!)

:boxing: -

How much torque you got there bigd:confused: ;)just enough for now
i know of one powerstroke thats on its third motor(7.3) best et of 14.3 so if you can get it to stay together then your allright by me

:help2: -good tuner, but some users give it a bad rep

Thanks bigd, I am trying:)


Well I'm slightly faster than 14.3 and probably got at least 400+ ft/lb of torque on your baby;)

Yes I was thinking about David's Snow White.

I made a mistake! But at least we know it won't be the last!):h

Yea Greg, I like to stir the pot occasionally....http://www.dieselplace.com/forum/images/smilies/stirthepot.gif

Keeps things interesting.http://www.dieselplace.com/forum/images/smilies/hihi.gif


Speaking of rods, yea you guys never window blocks do you?

hey trippen did you get my pm,mike

hey trippen did you get my pm,mikeMike,
I got both messages. I'm sorry I didn't get back to you right away. I had to do some checking.

Just come out and say you dont like Steve Cole on a personal level and to not buy the program becasue in your oppinion he is a **** or what ever. Why take small pot shots against his product that have no bearing on what the guy wants to do?

I DONT THINK ITS A PERSONAL LEVEL THING. ITS MORE OF A THING THAT MOST HERE DONT LIKE IT WHEN ONE VENDOR BASHES ANOTHER IN THE PUBLIC FORUMS:eek: IM SURE ATS'S SALES WENT UP AFTER THE LAST CHICKEN S H I T TALKING TOOK PLACE IN THE TRANNY FORUMS ;)

:confuzeld :help2: -not you, not ratlover but a couple east coasters

I live on the EAST COAST.............:cool:

Ultimatly I would need to reach the larger figures for just a few 1/4 mile runs and then we can tune it down to a safer 500 hp figure.


I suppose I missunderstood him. I suppose this wont be a DD, more of a toy/show vehicel?

The whole brand preference seems to get everyones feathers ruffled on both sides and the little jabs here and there and negativity get to me every now and then:o: :( It seems worse than ford/chevy/dodge. I shouldnt have snapped

I still say that its more of a personal thing than a problem with the product. And I suppose not buying from someone becasue of personal reasons is a valid reason. I have met Steve before in person, have talked to him on the phone and via pm's/emails a bit and he is actually nice to talk to. Some dont think so and thats thier deal, dosnt make them right or wrong. I have done/said some things that I could have done or said better but so it goes. I dont see Steve bad mouthing the comp using 1/2 truths or lies.

This got way OT and I shoulda just PMed fred. sorry:o: lets try to keep this guys post clean, we have PM's

You will lose power IMO with injectors if you arnt on spray or have a bigger turbo. So when you turn it down for the street you have a setup that cost a lot more $$$ and isnt making you anymore power untill you add more air(turbo or nitrous) Thats why I vote for propane. When you start throwing all that stuff together and adding all those tuning factors you start running on the ragged edge and may blow some sh!t the fCensored up. Be ready to pay if you want to play.

You won't lose power with injectors, you just need to manage the fuel delivery when off the bottle. It seems that some have not yet grasped the concept of what injectors bring to the table.

It is cheaper to install studs BEFORE you have head gasket issues than after. I know it's not the best way to do it (one out at a time) but it's good insurance. Now if the engine is out of the vehicle, it gets easier yet...

The major problem is running out of fuel in the fuel rails. So let's think about that and what the consequences are. If the fuel system can be emptied with stock injectors how are larger ones going to help? With stock injectors I can deliver more fuel than necessary from off idle to ~ 2500 RPM. From 2500 to 2800 RPM we have just enough fuel to go with boost levels @32psi. Above 2800 RPM the fuel rails begin dropping pressure because the fuel supply has been over run. All injectors do is make that happen sooner in the RPM band. Once the fuel supply issue is resolved then injectors may help but as of today that is not the case. There is nothing that injectors will do that can not be done within a good program until the fuel system problems are resolved. Now when you add a larger turbocharger and raise boost levels you will need more fuel depending on what boost levels can be reached at what RPM point. Most larger turbo's will make less boost at lower RPM and more boost at higher RPM's, so it all depend how much boost and where it occurs.

Stock or smaller programing injectors seem to show a gain but correct me if I'm wrong on the big programs like an Xtreme or a Quad juice stack you wont see a HP increase right?

What exactly do you mean manage the fuel?

Larger injectors allow you to inject the exact same amount of fuel in fewer degrees of cranshaft rotation. So you will make more power. A custom tune or smaller tune would be needed. The rail pressure will stay the same because in the end you are using the same amount of fuel.

You only will make more power if your taking to much time to get the fuel in......... and that's not the case at hand. As long as there is enough time for the proper power cycle to occur bigger injectors will do nothing for you, on the other hand they will drain the fuel rail much quicker than a stock injector under the same conditions. So by adding the bigger injectors you now need to add a new custom program to make them work properly, so what did you end up with......... a lighter wallet and the same power levels. :badidea:

Supposedly the Banks roadrace Dmax has a better pump and injectors direct from Bosch. Can anyone verify or dispute that? And who's kid would you have to kidnap to get access to them?

The write up on the Banks site claims Bosh is building them a new fuel system including the pump.

Knowing Banks they will claim they designed it and try and sale it for 10,000.00 dollars.

All we would need to do is a bit of kidnaping? You want me to be the wheel man or the guy hiding in the kids closet with the ductape and the gunny sack?

not you, not ratlover but a couple east coasters


Who are you talking about? I'm trying to see who else is on this end of the pond

If we don't get the Bosch.........I got a few bags of cement and a strong chain.........got any friends near a lake, RAT ??????

):h

Seriously though, it is rumored that some members may have a stronger CP3 than others do.......;) ........you know about those INTERNET RUMORS though.......

In my conversations with Peter, Yes they have a pretty elaborate CP3 Pump.
I do not think Banks will market it, but one never knows..... Banks has a lot of $$$$$ to 'throw into R&D'

They definately require attention...... they have more cool toys than their site advertises!:eek:

Actually, I got the injector/pump info from their site. Bosch is assisting them with the project truck.

Pardon if for a dumb question - but what the heck is a CP3?

Pardon if for a dumb question - but what the heck is a CP3?
That is the High pressure pump that supplies fuel to our fuel rails and is part of what makes a common rail diesel operate the way it does

pointless till the day....
You live near a lake don't ya............):h ):h ):h

I heard the Banks unit is mounted on the front of the engine using a custom made bracket, rather than in the "V".
