Borrowed a g-tech from Pat (2003blue5.7) today and made two passes. Best et was 13.25 @108 on 92 octane fuel and 9 psi boost.
Hopefully it will pick up enough to get in the twelves when the timing issues are worked out.
Thanks Pat for the loan of the g-tech and for riding with me and working it!
Kurt

Yee ha. Another turbo kit for our trucks!

Not bad at all for a tank! That was from a dead stop with the stumble? If so, it definitely has 12s in it.

Todd, I brake tourqed it but she still stumbles. Once the timing ramped up it spun the front tires a bit but we were on a industrial rd with salt on it. Should be good when we get the stumble out and the tune set.
Kurt

Nice! :)

How much does your truck weigh in at Kurt?

Nice! :)

How much does your truck weigh in at Kurt?
Not sure. I think around 5500#.Its stock plus the turbo and intercooler and about 3/4 tank of 92 octane. There was me 200 Pat (2003blue5.7) I'd guess he is around 175 and my son was in the back seat at 40 lbs plus his simpson child seat with 5 point harness.
Kurt

no problem,,, that was a fun ride. :o) truck pulls pretty hard...

simpson child seat with 5 point harness.

:hail: :D

Sounds like the truck is running good, let us know if you get that timing/stumble issue figured out. :)

got the timeing fixed?

Kurt posted it in the other thread in Truck Performance. Says the timing issue has been solved and another update coming soon!

got the timeing fixed?
Pat, Timing is repaired. I also ordererd a g-tech pro competition! I need to get another 1/4 time and some sixty foot info.
Kurt

Kurt where should I get my tune from around here?

Pat, if you are ready now I would say Livernois performance. If you are talking later this summer we could do it here. We currently only have a engine dyno, but the chassis roll is coming.
Stop by sometime and I will give you the nickel tour.

As far as I know, all the truck turbo tuning will be done in-house by W2W. If all works out, I will be heading up there this June to work for Kurt. Really looking forward to it :thumb:

I wanna new job too !

Pat, I don't do the tuning personally. I have one guy now that can use ls1 edit and another coming in june.(Todd /aka Reckless)
Call me at work at 586-757-1961 and we will set up the nickel tour. If you need my cell number e-mail me and i will get it to you.

The "nickel tour" is at least worth 50 cents in my opinion. Get ready to see lots of turbo stuff. Kurt seems to have an affinity for turbos :D

LMAO Pat the timing is fixed and the boost is set at 10 now. I am taking it home this weekend, if everything works out the customer will get it next week. So I won't be driving it either. Of course the red truck is almost road ready!

great but the red one is faster I bet huh?

great but the red one is faster I bet huh?
The red truck has a 4.8 in it now! The 4.8 made 500 at the flywheel with 600 ftlbs.
I have a 6.0 for the red truck that should make it faster than the blue truck. It made 740 hp at the flywheel and 900 ft lbs! I can't wait!
Kurt

I think the red one should still get me. :o( It would still be fun to tear up the road tho... I am thinking about doing my electric fans this weekend.. that will help a little.

Kurt....me thinks I will have to buy an Silverado SS after I get up there and throw some forged stuff in the motor and one of those kits :D We can dominate the truck classes at the LS1Tech events :thumb:

There's one coming up in Morocco indiana. Its called north vs south shootout.

I'll be going to that for sure, but won't be racing. Probably will help out Tom with running the race. I am sure Kurt will have that red truck there though :D

how far is it from MI.? I would like to go and race

Not sure how far Morocco is but it was less than a 5 hour ride for sure.
I just got my g-tech and it asked for the weight of the car. Put the truck on the scales and it was 5516 without me in it! Its amazing it can feel fast! Hope to get another 1/4 time this weekend with the timing fixed.
Kurt

Kurt....if you just take my wife out to a good Korean restaurant, all will be forgiven ;)

5516 pounds, really? How much weight did you add with the turbo parts? I'm suprised its that heavy. I know my 99 Z71 excab with basically the same drivetrain weighed just over 5100 without driver. I can't see my SS weighing that much more (at least I hope not).

Kurt, I think you'll like that Gtech. I like mine. I dont have any current logged runs or any nitrous runs, but here are a couple of NA runs from a few months back:

cool if you have time this weekend give me a call so we can compare the g-techs...

I think my truck is a lil bit slower with the headers?????

Pat, killed the trans saturday morning leaving at 12 psi with the timing in. Second launch at about 10 psi it just reved up. Drove it back to the shop without first gear, oops.
The only thing I got with the g-tech was sixty foot (1.88)

I was afraid of this. Sad to hear even with a beefed up tranny. What are the options for the tranny now? Allison? ;)

He really needs to spend a little effort and make up an output shaft for the 4L80E to mate with SS AWD transfer case. I'll buy one and I'm sure I can find a dozen others who would want one. Count XLR8NSS in for one as well.

Yep, that would be nice. :) I wouldn't even think about modding my current truck anymore if I knew there was a bulletproof trans option(aftermarket or otherwise) for the SS trucks. A 4L80E is what they should've come with in the first place. GM screwed up on that one. :bang:

Like I mentioned in the other thread though it would be better to keep the beefier 80e output shaft and modify the input of the transfer case.

Kurt - How about it? :D

tex you should try and hook yourself up with an autotrack from a 2500, i wouldn't be suprized if that splined part right inside the case was the same for the 2500autotrack and your case.

the 2 cases i have(2500HD and a 1500 auto) look exactly the same on the out side, i am sure some of the internal parts are the same. maybe some research at the dealer would tell you too. only other thing i can think of is geting that input hub machined out to take the 4l80e shaft, can that type of machining be done?

Here is some info from the manual transfer case options from GM. Looks like the 60E has a 27 spline Tcase and the 80E has a 32 spline. Does this sound correct?

Well after W2W starts selling turbo kits, that might just change for the better! ;)

I'm going to guess I added about 200-300 on the truck. If a stock SS ever comes by I will try and weigh it.

Hey Kurt FYI you have some competition out there
http://www.ststurbo.com/

I would not call that competition, unless you are happy with 350rwhp ;) Besides, what kind of truck owner would place the air inlet for their expensive turbo in that location? I guess if you live in SoCal where it never rains or snows, and the roads are always clean, then it would be fine. I doubt the tubo would last very long before needing a rebuild if you drive in any kind if weather. And how does that filter keep the turbo from sucking water when it is really wet outside? Is there some kind of shield that goes under the air cleaner?

Pat, I seen that system on a truck at the sema show. It seems interesting, simple install. Not sure how the cat will like being in front of the turbo. The old ford 2300's did it that way. I think our kit will be better for higher hp gains, only time will tell.

I like your set up by far... I'm saving my pennies. Hows the trans going anyway? oh there seems to be a bit of a difference between the g-tech's? Maybe it's because of the tranny?

Changing trans now. Should be fixed today. We think it rolled a sprag. I have not made a 1/4 run yet with my g-tech. I was going to on saturday but the trans would not have it! I launched it a couple times on the back street here, best 60 foot was 1.88. I will hopefully get a chance to run it the full 1/4 this week but there is no guarantee.
Kurt

Good to see I am not the only guy that likes to break parts :P

are you putting in a 4l80e this time?

Just slap in a 4l80e and see how that does in there
So your the guy Carl from rosslers was talking about "we been built a few AWD tranny's"
I'll be going the 4l80e routing in my truck the 60and 65 are just not up too the task with turbo's under the the hood

Switching to a 80e on awd truck might be tuff. The 4l65e should be strong enough for normal hot rod truck. In a all out truck the 80e should be a good bet but kinda expensive.
Kurt

A late model low-mile used 80E can be had for $1000-$1200. How much is a Rossler built 65E? I know FLP wants $2200+core for their "built" 65E. The 80E doesn't sound too expensive from that viewpoint.

Kurt I almost had my hands on one this past weekend! 4L80 it was a new one too. could still be able to get one... I keep My eyes open..

I was thinking more along the lines of you already have the trans in the truck. The 65e from Rossler is 2700. The 80e from Rossler is 3200, plus 1200 for core (I bought my 80e from local junk yard)but won't bolt in without modifications. Not sure what it will cost to fit to a SS Silverado awd box. Will need two new driveshafts if we make the swap.
This would be easy for the two wheel drive guys, just change driveshaft. I am working with the awd SS model at this time so will keep working with the 65e.
For those who want to race, Rossler has a three speed model of the 60- 65 trans user that should increase power holding ability. Sure would be nice if someone could make an easy swap to stronger trans with overdrive.

How about going with a Rosler TH400 and Gear Vendors OD unit? Could the existing transfer case on the SS bolt up? This would be the "ultimate option" but very costly of course. At least you'd never blow it up though ;)

Then I could run a BRAKE WITH FULL BOOST!! Ya AND some nitrous to help it spool faster. And 4 slicks vrrrrrrrrrrooooooooooooommmmmmmmmm



Easy does it.......I was gone for a minute, but i'm back now, whew that took alot out of me!
Kurt

Now you are catching on :D

i just picked up a built 4l80e from a builder in charlotte NC
the unit comes with all new electronics red clutches better band and trango shift kit
all for 1475shipped it's even the one with the top center bolt
rosslers real expensive for the 4l80e i thought but they do alot in there to help it live to big power
I've heard the 80s will handle near 700rwhp with just a shift kit ?

Pat,
It's back to driving like normal. Going to deliver the truck to customer late this week or early next week.
Ran my 6 litre on the dyno yesterday with new 67mm turbo.
Average tq from 3300-5500 848 ft lbs (Say bye bye mr transmission)
Average hp from 3300-5500 704 hp
Peak tq 903 ft lbs
peak hp 776
This engine should be in the truck in early summer.
Kurt

Was that chassis dyno and stock PCM Kurt? Nice numbers!
