FP HTA GT3076R to GT3586R

[92AWDTalonTSI]

What differences will I see by upgrading to 73-76mm compressor wheels?

Currently we have a 3076 @ .63 AR and want to go with the 35 @ .82.

Any input on this? Looking for 700s on 93.

To simplify, Should I upgrade turbos or upgrade the wheel?

The exducer spec on the standard 35R is 82mm; not sure where you're coming up with 76...unless you mean 86. The HTA86 is a FP-specific billet GT35R.

The 35R isn't really considered a 700hp turbo as it's max posted flow rating is 65 lb/min; not saying it isn't possible, however. You definitely wouldn't make 700hp on pump fuel with a 35R as you're going to be beating the shit out of it to get to that power level, and pump gas doesn't like hot air too much.

This is what I said:

>This is our goal, it's much more accepted to say whats going to help our goal and not what isn't. "Any input on this? Looking for 700s on 93." simply asks for your input and explains what we are looking for.

>I should have stated that all turbos in mention would be FP HTA. So increase that quoted lbs/min another ~10. The FP HTA GT3586 is on par with the 6262 and the PTE 6262 has seen numbers in the 800s.

You know what. I'll just upgrade to the 3586. It spools faster and has power in more mid range. Versus the PTE 6262.

But anyway, if anyone with the particular turbo (3076 HTA) wants to go a step further grab the 3586 HTA as it sits around 700-780 reliably on pump +Meth.

This is the GT3076...... Nothing was said about it being a 35R.

Then your title is a little misleading- it reads:

GT3076R to GT3586R

As soon as you introduce the number "35" to the mix, you're talking about a turbo with a 35R turbine.

I think what you meant to say was "3076 to 3086", which I'm not sure would even exist. Regardless, you wouldn't want to use such a large compressor wheel on a 30R turbine. You'd want the larger 35R turbine to be sure you're not going to experience too much turbine backpressure which will limit power output.

 

[92AWDTalonTSI]

Well I was leaning towards upgrading to a 35 from the 30. So that's why I posted 3076-3586. But, I understand. and will just go for the 3586 @ .82.

I think you should value and realize that all JusMX141 is doing is trying to HELP you in your decision. He is very knowledgeable when it comes to turbos, what they flow, capabilities, ect...

FWIW... I run the HTA3586. It's a very good turbo and packs a nasty punch for a mid framed turbo. I'd pair it more against the 6266 than the 6262, but that's my personal opinion. There are a few people that have made north of 800whp on this turbo, with Curt Brown being one of them, and Devin Shultz made very close just falling short in the high sevens I believe. This is all been done on E85, E98, or Q16/C16.. To say you want 700-800 from the pump out of this turbo even with meth is a little far fetched, though I'd say over 600 is very possible.

The 3586 is indeed a very stout little bi*** and it is still amazing me each time out. You will not be disappointed, though besides being able to say you made "x" amount of power throwing numbers out there, I'm not quite sure what your ultimate goal is. If your goal is 9's from a 35r framed turbo, then I'd say its very possible with the 3586 if built right.

I have a GT3076R that I paired up with the FP turbine housing, so essentially it is a FP3052 or "non-HTA" DSM76.

I've explored the same upgrade since I'm reaching the limits of this turbo. Your options are to either upgrade to the HTA 76 billet wheel and get 59 lb/min, or go to the 82 or 86 mm (up to 75 lb/min on the 86mm) wheels found on the GT35R frame.

The disadvantage to upgrading to the 82/86mm wheels are that the turbine in the GT30 will likely be too small to max out the compressor wheel. I know that in the FP housing I wouldn't be able to realize the full potential of either wheel, so I decided that I would wait and pick up an HTA 35R later down the road. However, that is because I want to stay with the FP-turbine because I am also using their manifold and have already tweaked my setup to fit that style turbo. If you are running a T3 and want to try their 82/86mm HTA upgrade in your current 30R, they will do it for $700 and then you could try one of the larger turbine housings to see if it will flow enough to see the advertised airflow from their compressors.

Oh no I understand Justin knows what he is talking about. But Again I wasn't very clear on my question. (Late night.) I will be going with the 3586 on E85. The problem is there is NO E85 for 15 miles. So manufacturing it or bulk buying is the only option. I'll be at Devin's on Sunday and I'll talk to him about his 3586. I'm thinking about 1600 cc injectors to complement the turbo and upgrading the fuel pump along with it.

15mi from an E85 station isn't a big deal at all. I'm that far from one, and the performance increas is so great I'd drive 50 mi. Just use that 15min trip as an excuse to go for a drive, take an extra 5 gallon can with you. And if your low and won't make it, just throw a gal or 2 of 93 in the tank. It will be just fine.

Also I'm pretty sure devin has been on a 3794 for the past season or two.

Amen to that. I drive 40 miles to the closest E85 station with 7 5gallon jugs in my DD every 2 weeks.

Definitely worth it.

How much power are you currently making on the 3076?

 

[JusMX141]

Also I'm pretty sure devin has been on a 3794 for the past season or two.

Car currently has a 6766; I know for a fact it had the 3794 at last year's DSM Shootout (2011) as he stayed at our hotel, but I believe when the car hit the track this year it had the 6766 installed.

Red Demon

Car was a consistent 168-170mph beast with the 3794 and seems just a couple MPH faster with the 6766...not sure what else was changed over last winter or what prompted the turbo swap to something that seems to make nearly the same power.

 

[bastarddsm]

hmm sneaky sneaky, he never posted on the local board about that. In fact he said he was running the 3794 at the beginning of the year.

I can't speak for the O.P., but I'm logging a little over 50 lb/min on my regular-wheel 3076R. Meaning, I'm at or over the advertised flow rating of the compressor. That's why I'm interested in this thread, I'm in the same boat and leaning towards the FP DSM82 or 86. Probably the 86, as I would be rolling over in my bed at night knowing I didn't get the biggest wheel. Gotta compensate, ya know?

1600's should be enough, but you might be pushing it on the HTA86.

I call E85 "Jesus Juice". It's amazing and addictive.

I just picked up the GTX3076R (billet wheel). I also have the tial SS vband housing .68 A/R. They said I can get 500HP no problem with my supporting mods. Also garret said if I get the .83 A/R I can max the GTX3076R at about 650HP. I will be running E85.

heavy head porting
evo3 intake manifold
4g63 non turbo throttle body
1500cc injectors
JMF vband exhaust mani
+1mm valves
brain crower 272 cams
revised lifters
eagle rods
wiseco .020 over pistons 8.5comp

I will be claying the head and reducing the squish, so my compression will rise when i am done.

lemme know what you think and feel free to ask me questions and i will try to get you information.

if you need more fuel just bump your fuel pressure up by 14.5psi (1bar)
