im not comparing it to a subaru. im comparing it to garretts. if turbo #1 spools better than turbo #2 while still making more power on car A, chances are turbo #1 will perform better on car B. thats all im saying.

Until we actually have results from one of the EFR turbos on a Subaru, it's all just hype and guesses on what they will and can do on a Subaru. I'm by no means saying they won't perform well, I just prefer proven results.

Telling people it was only at 32 psi to make that kind of power is kinda misleading also. A evo with a hta86 at 40psi will go 155-160 mph at the drag strip while a Subaru will go 135-140 normally. Best mph I've seen out of a Subaru on that turbo is 144 I believe. It will take a Subaru more boost then a evo to make that kind of power for sure.

generally an evo with the hta 86 isnt going to make 750whp at 32psi. it usually takes more like 35-40psi.

Psi is all relative to if the heads are stock, mild ported, or all out ported to the max ect ect... A 35r car with stock heads might make the same power at 30 psi as a 35r car with ported heads at 24 psi... n2oiroc I can't wait to see your results get is done asap lol! Btw I make 200 wtq @ 3250rpm airboy w/hta86 stock block(hybrid 2.5l) and 518whp 404wtq at just 25psi stock heads no porting...So that Sierra evo spool-up isn't all that impressive to me really...

Im not saying a hta86 will make that kind of power at that boost level. I was using that turbo as an example that a subaru at the same boost level with not make the same amount of power as a evo. I dont see a subaru making that kind of power at 32psi, thats why i said it was misleading.

PSI per horsepower is all about VE/powerband. I was able to make over 500WHP uncorrected on a dynojet using a stroker with ported heads/cams on only 19PSI out of a BW 83-75

This is with a stock block @ only 25psi hta86

Now imagine just 25psi with a good all out/race head port job...
btw that's just 3rd gear it spools even faster in fourth...

I'm interested to see what garretts billett wheel does comparing to forced performance... The bw efr series is another story that I'm interested in , but I need to see private parties test it before I even guess how it would act in the real world.

i would love to, but im out of money for now. in the past couple months i had to pay for my 8374, big ass custom cams and a headgames race head. i need to win the lottery! the big items i still need are a shep trans and transfer case, pistons and a good clutch. as far as the sierra sierra spool, on an evo i have never seen anything hit 200lb/ft as early and still make over 700whp. its usually one or the other.

gotcha. im not going to attempt to compare an evo to a subaru, and looking back i kind of came off that way. i have just been looking at a lot of evo dyno sheets and i cant find anything that puts out that kind of top end while making so much bottom end power.

the spool likes like what you would expect, but that torque come on early! nice! my 35r sti didnt come on that early.

These billett wheels are the **** ! Get your efr together I'm sure that billett comp wheel with the gamma ti turbine wheel should peform pretty well, im really interested in how fast you get that beast t spool...Yeah I'm interested in what this Garrett billett has to offer too Garrett wouldn't release it if it didn't work, right !?

I havent seen any results for the smaller GTX frame turbos, but i do know that the larger frame turbos like the GTX 42r's have worked very well for the people that have used them. I wish they would release a a 67mm inducer wheel version.

i really dont think the 35gtx will do better than the hta86, so far the gtx's are making more power, but spool is suffering.

spool on mine is going to be a tough one. my cams and intake are going to slow it down a bit but it should still spool as good as the sierra sierra evo.

We're definitely looking into getting a GTX for the time attack car.

and since we're talking about spooling a 35r here's our chart:



don't have the boost curve handy but it's hitting 32psi by about 4200 thanks to 2.6l and e85.

Looking forward to testing

I would expect that Garret has more funds for R & D so I hope these are superior

A shame it took them so long

We have had some great results in the UK with the Blouch billets. I run a 35R version, hopefully we can get some back to back results with the GTX versions soon.

This thread is digging into new ways of making more power earlier in the powerband, I think it's fine in this section...Jeff does some awesome reviews, so back off, sit back and get ready to enjoy some real data.

I had a hard time figuring out where to put this info also. But i found a few other turbo related posts so i thought this was a good place. Plus the fact that you will see some results very soon!

I don't know if that dyno works like a Mustang or a Dynapack, but if its like a Mustang and considering that the run started at 3000pm and floored at 3000, it seems to spool up about the same. I expect that the GTX3071 is going to act just like the GT3076R, but who really knows.

Perhaps these wheels will be more efficient at higher PRs. If that is the case I think these wheels will benefit the smaller displacement Evo and Honda guys.
Exactly! Its all speculation at this point (until tonight) that these turbos are going to really kick butt. I too see the potential for the 35R like power with the faster spooling 3076R feel. Who wouldn't' want that!

They are more efficient at higher PR which is fine, but for 90% of our customers, they are not going to care. Meaning, 90% of our turbo kit customers are going to run 20-25psi. The guys going above 25psi and running it all the time are rare customers. For those who want to make a race gas map, and run 30psi once and while, i am sure they will do well, but in all my testing, i run 14psi, 20psi, 22psi and 25psi. This works perfect to compare turbos for that larger group of customers.

The comparos with the EVO are really tough in my opinion. First off they run much more boost than an STI, so they might see a bigger benifit from the higher PR's where a Suby may not. Second, because the turbo is stuck the head (relative compared to our cars) a laggier turbo isn't quite as noticeable.

No clue! But in theory, you can do the GTX3076R with very little change to response and if nothing else make more power. The issue is, if the GTX3076R spools like the GT35R, then your simple answer is GT35R.

Still waiting on mine.....

I see conflicting info on the head/cam cars. Some show it being a worth while investment and others do not. I have a freind i am going to dyno his car in the next week with heads/cams and we will see how that compares to mine with stock heads and cams. The problem is there is never back to backs done to prove this. Not saying their should be, because its a huge pain. I have a feeling shops doing post up many comparos with heads/cams because they typically are the ones that sold them the parts and they would never show how the $2000k in parts got them very little. I am sure they work, but in the 20-25psi area most customer tune their cars to, my opinion its not worth it.

I would agree Garrett has more funds to test wheels so they should do better than the other billets out there. Because they have big bucks behind them they at least can provide us with graphs showing that they work. For some this will be enough to just buy one.

Also i wish they had these out a year ago. I think customers have been kind of bored with their turbo choices. Now at least there are 3 new viable choices, and if the other fit in the middle of them there are 5 potential choices.

Jeff,

The same thread shows what the Blouch billet 30R has done in comparison. Thought there were plenty of DD dynos in the states ? Could be wrong. Remember we use flywheel BHP also.

We need more testing and there will be more done. One test on one unit will not be the full story.

I am particularly interested in the GTX 35R to see if that will do better than the Blouch offering.

I did test a Blouch Billet 30R and i have results showing how it did, but it wasn't a 10% gain. The Billet Blouch did make more power from 6500 to 7000, but i was hoping for more than what we saw. I will post up results on that soon also.

Maybe worth a look at this thread, Scoobyclinic are the EU distributors for Blouch units. http://bbs.scoobynet.com/trader-anno...an-better.html
