or just running alot more boost through the intercooler than you should (big pressure drops/restrictions) and for long sustained periods in WOT.... just like in road racing, on a car that doesn't get the best flow through the cooler, which is what i originally stated You will always remove heat, i agree with that... but a large enough amount so that the intercooler can still be deemed effective... that's where the difference is.

 

Guess it depends on placement. Is there any particular one you are referring to?

I believe the ATI is ~95% efficient, at least from the temperature readings that have been posted on here. From pics that have been posted it doesn't look like the intercooler is in the best spot but it does its job well.

I didn't use an intercooler on a truck running a Vortech @6#'s, but then again it was running off of alcohol and had a low static CR.

Depending on the road course, speeds of 100+mph can easily be reached and there would be more than sufficient air flow to cool off the intake charge. I would think most manufacters out there would place the intercooler where it has a chance of getting some airflow through it. Unless you are running some rediculously high boost I don't think you have to worry much at all about heat soak on a road course.

well, I have the turbotech kit, it was a t-60 kit, I bought a t-70 and slid the compressor side into their exhaust side. so im not sure how well that turbo will work but it should do its job.

I have the 3" DP, and TT's new cross over that I havent gotten yet. and a large custom made spearco intercooler goof for like 1200FWHP. it blocks the radiator pretty good so im a little worried about that but well see.

once i get that cross over pipe here i am going to get it on and start her up. im shooting for 15psi, i want to see what this kit is capable of. im not going to dyno like rob has, but set it upand see what shell do.

I also have the alky kit, and a th400 with 12-bolt so ill loose a good bit of power through the drive train, but should make that back up in 60' at the track.

ill keep everyone posted
thanks
ed

 

id do what prostock john did and remove the bumper support and cutout your plate hole, thats what im planing.
with that TH400 im sure you get some low times, should be at low tens

 

Nope, we tried that with the TT kit already. We actually put nearly 100 pulls on that TTi kit at Ed Wright's on their dyno. The IC was too inefficient, the DP was too small, the manifold ports were badly misaligned, and the IC piping and crossover were too restrictive (too small).

As far as why nobody is making the power we are with our kit....we are the only people running a T76! Everyone else, with the exception of one person (who deoesn't/won't post here), is only running the T63...as far as I know.

FWIW, we made 500rwhp on pump gas within the first 5 dyno pulls after installing our turbo kit. And 570rwhp within the first 20 pulls. As soon as we put new valve springs on, we immediately jumped to well over 600rwhp with a stock engine. We hardly need anywhere near 150 pulls to duplicate our current HP levels. Those pulls were called "baby steps".

 

I think that itll be ok I took and slanted the radiator back a few more inches, and the intercooler only is on top of radiator in one spot.

there is about 5" at the base for air to get through, I am going to run some ducting up there.

Im hoping to dyno close to 600, and wouldnt mind busting into the 9's high ones. I may step up to their larger log manifold if I cant see my power levels.

i just want that pipe from them its been over a month now

ahhhhh

Back when you and ED wright were working with the TTI kit, tuning for the ls1 was in the stone age. I bought my kit back when you were messing with the TTi kit and ED wright had my PCM 7times and couldnt get it to idle decent let alone make any power. It wasnt untill LS1 EDIT was released that i was finally able to get it tuned decent. I picked up 70rwhp and 96rwtq going from the Ed Wright tune to Ls1 edit. Rob I`ll be the first to admit your a tuning genius when it comes to Ls1 turbos and I`ll bet if You got your hands on a TTI kit, with your expirience and LS1 Edit you could make good power with it. I guess we`ll see because i still want you to tune my car, this summer when i make my yearly trip to MN.

 

Who knows...you might be right. After the dyno results with the Formula, I don't anything would surprise me now.

And thanks for the compliment.

 

I don't care if Rob designed the ls1 pcm AND ls1edit....he ain't gonna get around the kits limitations with tuning. NO disrespect to Rob......he knows the kits limitations which is why he corrected them in his own kit. Ask yourself why TTi made a race kit when they already have a kit out with that 800fwhp intercooler and "t-76"

 

Hello children, lets play nice please. I didnt ask the questions to get opinions as much as I wanted fact or experience.
Rob appearantly knows how to tune a turboed car or his shop demo wouldnt be running as many dyno runs as it has already. Good job, I remember when yo first put that kit in the other car and your first "I tuned it first time using Edit" post.
I have talked with George at TTi and they do have a 3" DP option. They redesigned the manifold, the ports match, welds are complete and material is improved. Tubing is sized right and the IC is/has supported 800rwhp. I am sure, as I originally asked before, that noone has pushed this kit to its limit as it is now.
Yes, 2yrs ago the TTi Street Kit may have had problem (I am not saying it did as I never personally had one), but damn ppl, that was 2yrs ago. You think Rob woke up one morning and said, "gee I am going to make a turbo kit and its going to put down serious Dyno #'s on a stcok engine and and and and and....." ? No, he came out with a kit that addressed the downfalls of a then problemed kit, and as we have all witnessed following the posts, he has grown as a tuner, and developer. This doesnt take away the fact that the TTi kit is capable, and could be much more than what some are pushing it to. Thats why I posted this. I want to know, since the revisions to the kit, has anyone had the same OLD problems: Manifold cracking (I hear the answer is no), the ports being misaligned (heard it was fixed), the DP being made optional to a 3" (should be more than enough), tubing (that too) and the IC efficiency-still got no answer on the %, but again was told it is capable. Now, I too would like to see this kit with a T76 and the 3"DP. I will be talking with George about shipping my car there while I am deployed to hook this up, get the power I want and or redesign a race kit that keeps the AC.

thanks for the info.

Charlie.

 

i think the street kit could be cable of more then 600rwhp, cablebandit was close, and i will be too soon
oh on pump as well, with no alki.

also ive been looking at my engine and think they could move the altinator up like the street kit and movve the AC were the altinator used to be.

 

I may have to give George a call then about purchasing the 3" DP with the T76 upgrade. (still running the smaller one with the T60-1).

Smokinhawk...that griffin intercooler you are getting, will it bolt right up using the intercooler piping from the TTi kit?

I have the T60-1 kit and had no problems out of it yet. Anyone upgrade their wastegate to a better one? The Deltagate isn't gonna cut it when I get the T76 and up the boost to 12-14lbs.

 

no the IC will not bolt right up
the inlet/outlet for the TTi IC are angled, the Griffen straight.

im not goign to be putting it in the same spot either, placing it were the bumper support is like PSJ's

your right on the wastegate, defintaly need a bigger one.

 

The only big differances Between robs kit and the TTI kit is 1. intercooler endtanks 2. wastgate location 3. the old TTI kits had a 1/4in smaller log. So out of these three things what is limiting the kits HP potential. How can the endtanks make that much of a differance? Maybe they do, but I don`t understand how.


"[/QUOTE]Ask yourself why TTi made a race kit when they already have a kit out with that 800fwhp intercooler and "t-76"[/QUOTE].

Umm, more efficent and the potential to make over 1000hp The street kit was only desined to run up to 600hp efficently. After that backpressure becomes higher then it should be. But that don`t mean it won`t make more power.

George told me he had a guy with his street kit that was making 670RWHP @ 13psi and race fuel, with his new log and the T76 upgrade. He wouldnt get to far into it but he did say it was a fully built low compression motor.

 

I had EFI live V6 hooked up to my car a couple of weeks ago while it was idling. When I got into the car to check things out the IAT was 102 and it was 60 degrees outside. For what it is worth the minute I started to drive the car the IAT quickly fell down to 72* that was below 50mph and some quick stabs to WOT. So yes there was some heat soak while the car was not moving. An Air to Air only works when there is Air to Air...and then it works really well. So far I believe the fastest LSx FI car is running an Air to Air I/C...not trying to say the water/air I/C are not any good because they are..just an observation.

A good example of 100% Efficient I/Cs are those used in off shore racing..where Ocean water can be used to cool the charge to lower than ambient..

 

TTi's "800fwhp" kit never showed anyone the money.

I would suppose that TTi finally (after MANY years) made something that works better, with seed money from a Va. sucker. It certainly paid off, no question. George wasn't going to go out there with his own money though. Certainly, he never did until someone called out his current kit. The bottom line is that George's kit still hasn't shown anything more than the log kit (choked out as it is).

His newest kit is great, and I would love to display it, but, without knowing the costs (absolutely on a 2x magnitude of that which I spent) I can't see how the money would be warranted. If I lost (and that's a BIG if), I wouldn't be sorry when I spent half, or less, the cabbage that Va.-boy spent.

SC-

 

my bad ss, i should have coppied you on the invoice. you're wrong (again).. how much i paid is between myself and george, but the total in hard parts is LESS than i spent on the qmp kit the 5 months i had it... in addition, public pricing has been here for maybe 3 weeks now :

First blood = "seed money from a Va. sucker"

Keep it tech or get a PM from me.

 

Rob what do you think the difference is? My thoughts are intercooler doesn't flow nearly what Robs does and/or is not nearly as efficient. The log......I added bigger primaries to mine and don't think that really helped. Crossover.....I used a Mac header and 2.5 crossover...no real help. The t-76 has a machined t-6? compressor housing so it will fit.....this is choking it too. I made 573rwhp at 13psi with the kit but the IATs were terrible. Oh...that was with the 3" dp as well on a low compression 346. It is not that the TTi kit hasn't been turned up, it's that Robs kit has better components.

 

See thats exactly what i mean. All the changes you made and the kit still didn`t perform to you expectations. Yet after all the changes you basicly had a QMP kit. I do wonder if maybe the endtanks are a restriction but it still should make over 600hp, Just less efficently.
