Well that's true, but that's in 5th. Besides I'd like to see what just the TransGo can do to help it. It's supposed to be a big help for the stock tranny. When I order mine, I'm gonna see how far a TransGo and converter will take me...

 

I'd like to try that, too. I talked to the guy at suncoast and he said that the converter/shift kit combo will make sure that you are getting all your power to the ground in every gear up to and maybe slightly beyond +150 hp.

I hear that the competition hot juice/attitude monitor makes some REALLY sick power when there's a trans with some upgrades behind the engine.

 

I could swear I saw the TransGo alone would get it to like 500-600hp. Heck, I'd start with that as it's only $200 for the kit vs ~$1400 for the converter + install! I've been runnin' my 4L60E w/o TqMgt with just a TransGo and it's getting close to 70K mi now! I'm going to see if a stock internal with a TransGo and servos can hold a 6.0 HO and a cam...

Anyway back to that Allison, so with Suncoast's converter and the TransGo... over 400rwhp is attainable with a stock internal Allison?

How much do you think you are defueling with the Hot OJ box on the stock Allison now?

 

In level 5, which is 125 hp/325 tq on my chip, I can tell there is pretty good amount of defueling going on. I have the defueling during locked shifts turned on to help protect the stock transmission, and man you can really feel it. I'm also almost positive that the juice is reducing the power somewhat in 5th gear while in level 5. I say this because in all the other gears the truck will always smoke black a little at WOT even when turbo reaches full boost, but in 5th it won't do it. Probably wont take all 325 extra tq in 5th gear. For example, take off full throttle from a stop and the truck will smoke black through the first 4 gears and as soon as it hits 5th the black smoke stops. OTOH, if I set the juice to level 4 (+90 hp/250 tq) I can tell the truck is down on power even in 5th gear, so it must be able to handle more than that in any gear.

 

Damn! Good times for the truck.

 

Hrm, sounds like there's a lot to be left with that Edge box alone! Good info here and gets me to thinking... that a converter will happen sooner than later.

 

Yeah, I wonder what just the edge box with a trans that could handle will do.

 

This is what saw on tdp a few weeks ago as best as remember. I looked and looked for the thread so I could post a link but it appears to be gone for some reason.

Anyway, here's basically what it said.. a couple of basically stock duramax trucks that both had built allisons installed in them were dynoed. These trucks maybe had exhaust and intake, but that's it....in other words no tuning. Then they had the competition juice aka hot juice w/attitude installed, which is rated at +145 hp. When they were dynoed, IIRC both trucks picked up about 210 rwhp because of the beefed up allisons. I don't know the exact gain, but I know they both supposedly gained in excess of 200 rwhp from ONE chip.

I wish edge didn't make the names of all thier stuff so damn confusing. Plus there are about 9329047751 different combos of stuff you can buy.

Here's the breakdown as I understand it, just for clarification.

competition juice aka hot juice/attitude which is the hot juice chip with attitude monitor installed.....+145 hp in level 5 and +125 hp in level 4

standard juice with attitude monitor installed.....+125 hp in level 5 and +90 hp in level 4

hot juice chip with no attitude monitor installed.....+125 hp in level 5 and +90 in level 4

standard juice chip with no attitude monitor installed....+90 hp in level 4 and does not have a level 5.

I have the standard juice with attitude. The 145 tune is pretty much a nono without transmission upgrades I hear. Some trucks with no trans upgrades will apparently hold the 145 tune without going into limp mode, but only because the juice is defueling massively so the bone stock allison will live. People have also found that trucks without transmission upgrades will often produce more rwhp with the 125 hp tune because the juice is defueling all the time in 145 mode.

The suncoast stage 2 kit is probably what I would buy for my truck if I get anything. It comes with the torque converter, shift kit and stock replacement c1, c2 and c3 clutch packs. The guy told me the reason for this is that if any of those clutch packs are burnt the shift will not increase your holding power. The stage 3 kit is basically the same except it comes aftermarket clutch packs with increased friction area. I think the stage 3 upgrade may also increase line pressure. They claim the stage 3 will hold 500+ hp. stage 2 is 1700 bucks and stage 3 is 2200

The guy with the 11 sec Dmax has an ATS transmission, but I don't know that much about thier stuff.

 

i know personally that our stock duramax made 402 rwhp on a mustang dyno and on the same day and same tune but with a ATS tranny and convertor, the other guy made 435 rwhp. same day, same dyno, same hot juice with attitude monitor. i would have to believe that 4" exhaust and intake tube and filter would add power at that level. adding 200 rwhp, that would be INSANE. but maybe it is true from just a single juice competition.

 

Damn over 50whp worth of defueling is crazy! I too think if I were to pull that tranny, I'd go ahead and replace most of the clutch packs to save labor. Labor is going to hurt ya pretty bad on the R&R so a few hundred more isn't gonna break the bank when you're out over $1800 already.

So much potential, so little money to work with!

I also read the '04 Allisons have some extra shift solenoid and that the 1000 Series tranny has the capacity for a 6th gear due to the three planetary sets...
