Couldn't find any tests of the GTX3071R but from all the info I got it looks to be a really good turbo for what I am wanting so I went ahead and ordered one along with some other parts. I don't know how much info I will have but I know I'll at least have a dyno graph to show you guys once it's all done.

Just so you guys are aware this will be installed on an Evo 8 stock 2.0 block and mods will be: GTX3071R, GSC S2 Cams, GSC Beehive springs/retainers/seats, Shep Trans (Stocker is on it's last leg), Exedy Twin Disc, Upgraded Intercooler and Piping , Intake, Evo 9 BOV, Megan 02 Housing, 3in. Downpipe and 3in. Exhaust and 3in. Test Pipe, Buschur Ported Intake Manifold, Buschur 65mm Throttle Body, Walbro Fuel Pump, 1000cc Injectors, ARP Headstuds, and Spark Tech Non CDI COP Ignition System. Sorry I don't know the brands of the intercooler, piping, exhaust, or test pipe but It will still give most a good look as to what it can do.

I don't know how much boost it will be tuned at yet but hoping to break 400WHP on the dyno. Also it will be tuned on 93 pump gas. Sorry all you E85 guys. Most of the work and tune will be done by AMS. I will try to keep you guys updated and should be completed in less than a month since all parts are already ordered. I can also upload some pics of the turbo once I get it and any other parts if anyone wants me to. I'm really looking forward to sharing the numbers with the community since I myself couldn't find much info.

Also questions to some of you more experienced Evo'ers. Do you think my 400WHP goal on AMS's mustang dyno is a good goal and what power if not do you think I'll have? Just for reference I have a stock 8 turbo at 27PSI on it now with the exhaust parts listed, intercooler/piping, walbro, and exedy twin disc and was previously tuned by AMS and was at 325/325. Also if theres any parts you guys would suggest should also be done at the same time please let me know. I'm trying to get as much as I can done in the single trip there since it's almost 4 hours away. Thanks.

 

good luck with this!

 

I see the Megan o2 housing in your mods, so im assuming your gonna use the ATP GTX3071R, correct?

 

400whp with a gtx3071 is very achievable. My tuner make 530whp with a 3076/3037 and SR22.
If you're going to run a twin scroll housing, you will have near stock spool too.

 

Sorry I forgot but yes it will be the ATP stock location version. I'm still hoping to get some good numbers though and might even have the exhaust manifold ported when it gets done. Anyone think it would be worth the extra money since its already going to be in the shop for all the other work?

 

Looking forward to seeing some results as I'm in the market for the GTX 3076R.

 

With E85, it should do around 500whp on a dynojet. 91 octane is probably around 400whp. 93 octane is probably close to 440-450whp or so, give or take. So I think it'll do over 400whp on the Mustang dyno, though if you're trying to tune it right now in the 100+ F temps, maybe not so much.

 

Still waiting on parts. Hoping it cools down quite a bit before I head up to AMS for the tune. Really excited to share the results. CANT WAIT!

 

Any New News???

 

I have in my head CarlR does your tuning? I thought his was 530hp on a Dynapack using E85? If things were equalised so he had to use normal petrol, had AWD transmission losses and did it on a Mustang dyno I'd guess it could be quite a challenge to get much over 400whp.

 

Yup he makes ~530WHP on E85 and Pump gas. The compressor is out of flow, E85 and Pump gas make very similar numbers. E85 increases the midrange.

We are testing the GTX3076 this weekend, so we'll see how well that performs.
He is now using a Twin scroll housing, which makes full boost between 3600-3800rpm.

E85 vs Pump gas (single scroll 3076, SR22)(23psi peak, 21psi at redline)
adding/changing the correction method moves the numbers about 5kw. Not much.

 

Sorry it's been so long since an update. Had some problems with getting some of my parts. They are all in now and scheduled to drop it off on the 30th of this month. So hopefully I'll have some numbers for you soon after that. It all depends on how bad of shape the drivetrain is in really. Planning on a ShepTrans but if the TCase is bad then it will take a bit longer because it will have to be shipped out. Really looking forward to posting the results but until then heres a pic of the turbo. Went with the stock sized inlet so it doesn't look as cool as the 4in inlet but it should still put a smile on my face.

 

On my 2G DSM, I had a mistu flanged 3076R and made 370whp/320wtq on STM's Mustang Dyno at 26psi on 93oct. At that power level I was trapping 121 consistently. I switched over to E85 and made 427whp/359wtq and trapped 126/127. This was on Comp 272's (10.8mm/10.2mm) so with a more aggressive cam I could've seen closer to 450whp before I maxed out the single 255. I also had the port shrouded housing and mine was powder coated black. For a street setup this is my preferred turbo all day.

 

Just wanted to update you guys but sorry still no numbers. I have an appointment on the 30th as long as my turbo gets back here in time. I sent it back to ATP to have the compressor housing swapped to the bigger 4in. inlet and ordered a 4in. intake for it. As long as it gets back by then I should have some numbers around the beginning of next month. Sorry it has taken so long and I'm sure I'm more anxious than anyone else to see these results. I will update you ASAP and if the Turbo gets back here in time I'll try to post a pic with the bigger compressor housing. I know it looks alot better on ATP's website so hopefully it will look and perform even better than the initial smaller housing. Also wanted to get some opinions on if a different intercooler and the shorter upper pipe with a small battery would be worth it? I think they intercooler I'm running now is a TurboXS and the piping is aftermarket but just not the short route where you need the small battery for. Just trying to maximize the power with good bolt-ons since I'll be running pump gas. Trying to get these numbers around or mayber even higher than some of our expectations!
