Update results. This time a high flow of a R34 GTT's OP6 turbocharger. Turbo's running our SS2 profile with custom 4 inches front housing, externally gated on E85 fuel. Car's got a stock RB25DE Neo that made astonishing 411rwkws. Thats the highest I've seen out a NA+T so far.

Another result to share. This one is with our new ATR45SS2-RB26 version in T4 .82 rear on an R33 GTST Rb25det motor. This turbochargers uses one of our custom made turbine wheel that worked extremely well, and I'm truely amazed of how well factory RB25det stock cams are capable of. Final result of 1011rwhp @ 37psi with Nos or 850rwhp without.

Might worth checkout shaft runout and balancing.

Updating result. ATR45SS-0 Ball bearing turbo on a Rb25det Neo motor with stock cams and built buttom end. Car made a super responsive 512rwkws plumbed back @ 32psi, and 500rwkws externally gated @ 28psi.

I still have Garrett parts to build GTX2860 if interested.
-
Check to see what KTX has to offer. You will want it to stay the same bore size and similar wheel height that has slightly bigger inducer. I do shaft balancing, custom housing profile and machining if u want to drop / send them in when ready.
-
You find EFR turbine explodes into a million pieces once they over speed (while Garrett's snaps turbine head right off the shaft). Good idea to install a speed sensor and monitor rotor speed. Upsize comp wheel is relatively easy, install new front wheel, balance the chra, then profile and machine front housing.
-
Quick product range update. Externally gated and externally gated plumb back rear housings are now available in a kit with turbosmart 45mm gate. They are good for sub 700whp applications, can work with all Garrett GT30/35 series cores as well as all Hypergear's High flows and ATR series. PM for details if interested.

Assuming the intercooler is efficient. From the dyno reading, the compressor is unable to keep up with engine speed at holding constant boost pressure, its a usual indication that the compressor wheel is maxed out. At that point when wastegate is loaded to increase turbine speed, compressor discharge temp skyrockets. PS. I wouldn't worry too much about the graphs or data manufacture put out there, they will be apprximate depending on application.

Twicked this turbo alittle bit, Made same power, picked up another 500RPM of response and 100kws in mid range at same boost level or 23psi, still running out fuel even with an extra pump. I think the original version of SS3Pro would peek 70kws more at full capacity. -

Im on this page as I've been tagged. Im usually under Forced induction section. Lots of new developments, builts, results and videos has been added in last 4 years.
-
TS T4 can build in .86 rear. I can re-configurate the wheel configuration to be reasonably responsive that makes the power. But will not be as responsive as in T3 .63 rear.
-
No, that was in T3 .63 rear housing
-
T3 housing was used on that drift car and recommended to run on Rb25det motors.

SS3Pro is a modern hybrid combination of a turbo. It came out of a mixed & matched wheel set during our R34 GTR turbo development. This one is very driveable with good power to boost ratio. It pulled 444awkws on 23PSI. Its then put on to an R33 drift car with a stock spec forged engine that pulled 456rwkws @ 24psi. All in by 4K This sort of power band would be a good street car or a track car.
