Pagman dyno'd 390 WHP at 22 psi, and 400 something @ 24 psi.
A bunch do, at least in SoCal.. Boost wise, this is about 200 RPM slower than S3 at least from the butt dyno.. Neverthleless, it doesn't run out of breath at top. It's smaller brother, the GT2871R would be about the same as S3 spool wise.
Too bad there ain't no proper standalone, hence mine's for sale (ATP kit). Anything bigger than this turbo is a big waste of time in a FWD car (and will most likely destroy your oil pump).
To get a good comparison on how this turbo performs, take a look at the EVO owners w/ the same turbo.. Their stock turbo pretty much spools like S3 (16g), and the 3071R's only spool up slightly later, neverthleless makes quite a bit more power.
This turbo, S2 injectors, S2 PCM, and a return fuel kit at 58 psi base would be a darned good street combo (at the street boost levels the S2 ECU is designed for - 15-18 psi).
In regards to the ATP kit, the O2 housing is not very well built.
This turbo, coupled with the KINETIC MOTORSPORTS hardware (also uses a cast manifold, *MUCH BETTER O2 HOUSING*), coupled with SIEMENS DEKA 630 cc/mins injectors, Return fuel kit and an AEM EMS == heaven.
I am really looking into this turbo as well, I am not a big fan of the 50trim as this has just as much potential and spools faster = better turbo on the street...if you want a drag type turbo then get a GT40 anything in between is just a waste in my opinion.
However I dislike the log manifold...it is great that it is cast but I want a good tubular manifold to go along with this turbo (AMS, ultimate performance) or a cast tubular (psifi when ever it comes out).

Sold the car to a guy in houston Nivo...before i could dyno it. I did run a 12.1 and backed it up with a 12.0

Nivo is that like a hint hint...wait for a few months ? Fire me a PM if you have more information so I do not cloud your thread with other information.

damn it, why is it that no one ever posts their GT3071R dynos. I did know that traxman99 did 420whp at 23psi, using the emanage and his own correction.
Which is really good for this turbo since it dies out after 26psi on our engines.

thats so odd.. i think the answer to that "issue" lies in the srt's rpm band.... i think that could def be solved w/a deck plate and/or lengthened rod/custom piston combo... i've seen "other" types of cars make quite a bit more hp similar boost levels

anything over 26psi and you are already nearing the inefficient islands on the compressor map. That coupled with a small turbine housing, top end falls off dramatically. these are ment as street turbos for quick responce and little lag.
I've yet to see another dyno of the GT3071R on an SRT-4 pushing it to 26psi or so.

if it didnt sell i was actually gonna buy 750s, retune and turn it up to 24-25psi on a 100oct. + a lil Xylene
