I;ve been avoiding the t3 deal not because of a cost mostly because of response and spool on the track . The T3 will make far more power without a doubt and just easy to deal with when it comes to swapping things when your not happy.

I would second what hiboost said about being worried about blowing the block. I'm going to let it ride and see how long it holds up. It's completely a track car so we will see how it holds up to 100oct + hiboost on a constant basis. Worst case is i go 2.3 or 2.2 i guess lol , then I would really get to see what this turbo can handle.

Creating heat on a canyon run or the street is one thing and heat at the from abuse at track are two entirely different issues i do have a data logger so it will be interesting to see what my EGT & oil temp gets up to with this setup, i'm not bashing on the red i think it's a great turbo for what it is , i just rather not go with the stock housing. For me i think this is the best plan, to keep a decent spool and power curve without having to go nuts on the block quite yet. Not that it's not in the plans. But more power also means more tires and brakes.

 

Is ATP releasing the housing or is it another company?

 

atp

 

What about a regular 3076 with an HTA wheel? you would still be able to call that a bolt on so will that be similar to the gtx?

 

Well the HTA 3076 flows 57lb/m so it flows slightly less than the GTX it would be interesting to see a head to head spool vs power dyno graph.

 

Im curious about that as well.

 

i would go 3076 over fp for sure, wasnt impressed with my fpred

 

Could you mention why? By all accounts, the red makes more power, spools similar, etc. Why were you disappointed?

 

A lot of people throw a turbo on a car with little to no supporting mods expecting to see awesome results...I am guessing he was one of them.

 

Just curious, have you driven a X with the 3076? Because, by all accounts, people that I have spoken to in person that have used both the Red and the 3076 prefer the 3076. They state better power and transient response.

 

The garret bolt-on 3076 for the X? Or are you, being an evo 8 owner, assuming once again that the entire world revolves around your outdated chassis and engine? On the X, the bolt-on 3076 is a piece of ****. It flows nothing like a real 3076 w/a T3 housing. And the dyno plots from all... three? people who have it, prove that it is weak vs the red. Hiboost is the final authority on this turbo, he races one. And he had to spend tons of $ to make it work decently, and has said before that a red would be quite a bit better. And seeing how this thread compares it to a black, there is no comparison. At all.

 

He had to spend tons of money? Aside from the wastegate failure, he did NOTHING outside of what any other Evo X owner does for their car. What's this tons of money? He doesn't even have cams? He's still completely stock bottom end. He does have his prototype intake manifold, but he did that in conjuntion with helping a friend. I'd say there are MANY guys with significantly more money into the engine than him.

Funny you mention racing. You know that WORKS Evo X in the BFGoodrich commericals? Check out the sticker on the rear bumper. It has the Garrett turbo on it and they placed 2nd overall IIRC in the Redline time attack at Infineon. The Stoptech time attack Evo X raced with it even with the crap wastegate and generally either placed first or second in their events with the primary car swapping 1st places with them being the COBB STI. I think it was the Import Tuner Evo vs STI battle where the blue Evo X with the Garrrett put down the fastest time in the first session out and didn't even go out again. The Dent Sport guys on the east coast use it on the Evo X they helped build for hill climb events. I hang out with the guys are RRE once in a while, and they'll only use the Garrett. These are guys that do real racing and I think most of them started off on the Red. I've seen the dynos from Stoptech showing the 3076 makes better power. Ask RRE, they'll tell you the 3076 makes better power as they've dyno'd both. Ask Dentsport, they'll tell you the Garrett makes more power and they've dyno'd both. Go ahead, call them up. These are guys that have tested both on the same cars, not bench racing. You say the Red is better than the Garrett, and I've yet to see anything to back it up. You call up any of the guys I mentioned, and they tell you with evidence to back it up the 3076 makes more power. How many guys are out there racing with the Red? I only know of one, and that's Jon of former HB Speed, now COBB So Cal.

Lastly, your assumption that just because I own an 8, I think 'the entire world revolves around... blah blah blah' just goes to show that you jump to conclusions with no real information.

 

Was kinda a low blow :-) just used to 8/9 owners assuming that everything is like their cars, sorry b/c you're not like that.
Hiboost had to spend forever on his tune, had to go external wg, had to buy a tubular, and in the end puts down numbers akin to a red w/o tubular etc. It's just not that high-flowing a turbo. If they put the gtx3076 wheel in it (I think atp is working on that) then it'd be quite nice I think. But in the end, the black is a much better turbo, and those race teams you mention have never posted a dyno that I can find, I google and search for their cars and I can't find hardly anything on them.

End of the day, this thread is black vs 3076, and there's no comparison. That HKS GTII looks like the **** if you want fast spool vs the 3076

 

Well we are comparing the GTX not the old GT , most likely the black will outflow an ATP bolt on .. But no one has results yet so it's not set in stone.

 

I wish FP (and CBRD too) would post the sizes of the wheels in their turbos, but they don't. But as far as I know, the Black is basically GT35 size, so it SHOULD make more power than a GTX3076. A more reasonable comparison would be a GT3582 to the Black though. Looking at the maps on the Garrett website, the GT3582 flows more than the GTX3076 on the compressor side, plus the bigger turbine should reduce the backpressure.

Based on the testing Perrin has been doing with the GTX series, I think a GTX3076 could gain ~40whp over a regular GT if both are pushed to the extremes.

I've learned one thing from hanging out with racers, they don't spend much time on the internet That, and they don't want others knowing what they have. I could not find a dyno nor mod list of the COBB STI to save my life.

But I did ask the Stoptech guys for their dyno from ~2 year ago since I know those guys and it's attached; 2.2L cosworth block/head/cams on MS109 fuel.

Dentsport has a dyno on their website which I attached, unknow on the mods and I'd assume pump fuel.
