Rear Mount GTO Pics

Just finished up a rear mount on a 2005 GTO. He supplied the major parts (turbo, intercooler, wg, bov, fuel parts) we took care of the rest. Pretty happy with the way it came out. Currently at 5 psi and will likely turn it up to 8 psi in a week or so after he drives it around a little. Put down 403hp and 413ftlbs on a mustang dyno, cant wait to see what it does turned up some.
Parts rundown:
2005 GTO
Stock LS2
Stock A4
Masterpower 70mm .96 AR
2.5" hotside and coldside
Ebay 3" core intercooler
Tial BOV
Turbosmart 38mm Wastegate
Walbro intank with 72# injectors
SD Tune

nice to see one of these. I recently saw one a few months ago on a new camaro. clean kit. I bought one for my trans am years ago when they were still working the kinks out of it, so I did my own modifications.

the power goal before we started was roughly 480 at around 8#'s, im pretty confident itll do it. the 5# numbers are about what I would expect.
I suggested 3" hotside but the customer wanted 2.5". At this point I don't think its holding it back but it will probably play a part with more boost.

I was thinking the same thing, that the remote mount may need a smaller dia hotside to make up for the lack of heat in the turbine housing...I wonder if lag would increase (how ever negligible an amount) from switching to a 3in?

Wow thats alot of piping. Turn the boost up. 5 psi is hardly worth doing speicaly with how far that air has to travel. It looks good dont get me wrong but a cam tune long tubes and ls6 intake manifold would have made close to that on a dyno jet. Every mustang dyno in my area reads 50-60 wheel higher then a dynojet

in regards to mustang vs dynojet numbers, our dyno reads about 4-5% lower than dynojets on RWD and FWD applications, about 10% on AWD. At least that is what we have seen on cars so far

This is my car and I absolutely love it. The piping is perfectly sized for quicker spool times. The boost will eventually be turned up. I would love to see a cammed, intake, long tubes put on 70+ horsepower by spending $30. Pop a different spring and boom. This car drives stock when not in boost, it spools quick, and holds boost. Nothing was compromised and the guys at SS Performance did a phenomenal job on this build. A lot of research was done prior to the build and this car will EASILY attain higher numbers with a quick spring swap or boost controller. Right now, I'm enjoying hearing that turbo and the feeling when I lift off the gas of having this bov just scream at you after you just got sideways. Cam and long tubes just don't do it for me.

Congrats and I totally agree... Turbo's sound SO sweet...
hey... under cruising (just cruising around town at part-throttle) can you hear your turbo spooling up and down when you accelerate/decelerate?
Also... when that gate opens up, what does she sound like?
Sounds like a bunch of air escaping? or?...
Looks GREAT!!! I LOVE it!

Def one of the cleanest rear mount GTOs Ive ever seen. I cant imagine having turbos and under 500hp... although thats obviously what the customer wants. Im sure he will be back wanting bigger in a couple months.

i bump for 3" exhaust...should notice a difference.
with regards to the power and boost... 5psi is not a lot of boost at all...it will tremendously pick up power as you up the boost.
I know.
