Ok excuse my ignorance. Better turbine side equalls less drive pressure or just more lbs/min or both?
GT50's are coming for you compound guys ;)
- Thread starter DRTurbo
- Start date
It is both.

Cheap and Easy.
Bump.
When equal A/R's are used their should be no difference. Now here is where it gets muddy. A 1.00A/R open is not the same as a 1.00 divided. To achieve the same spool with a open housing, you would need ~.92A/R housing. The divider is typically not taken into account when A/R is calculated.
They are making some killer power too!

Wrong.
According to the Thumper turbo thread:
DRTurbo replied "the S400 turbine with 1.32A/R housing flows around 63-65lbs/min max.....or in other words will support about ~138lbs/min max om compressor side."
According to the information in the other thread, due to the smaller housings, this turbo's larger turbine flows less than the 1.32 88/96 combo?

Yes sir they did. We have them already.....actually have had them now for over 6 months
. We CNC them here in house for a few other companies now. They really are awesome units and that 98mm UHP turbine is just awesome.
They made changes
. GT50 turbine wheel with 1.08A/R ~ flows the same as the 96mm 1.32 combo. Turbine wheel is now a 99.06/90.78. :rockwoot: All the A/R's from the GT47 will be available as well. :Cheer:JustinOlson

Any pictures of these? What is peak the efficiency of the turbine wheel?

I believe the gt50 wheel is around 78-79 percent efficient according to a post from Jose on yellowbullet.
Gt47-88 housing
Can you guys give me some advice please i am running a GT47-88 T6 with 0.96 a/r i am wanting a rear divided housing to run a QSv can you supply on in size 1.39 please? Also how much more power/lag will i get from changing the rear housing from a 0.96 to 1.39 on a 3.0L supra? Spool is now 5500rpm on stage 4 cams so very laggy,... : Car currently makes just under 1200bhp with 2 bar boost and 8200rpm will be revving to 9500rpm is the turbo can support this! cheers Stu

Id email or call jose(forced inductions)he ll answer all your questions.
Stu right now the GT47 divided housings are rare and hard to get. We get 1 or 2 every once in a while. The 2JZ works well with them with the QSV indeed. We have been though switching some 2JZ's over to the GT50 and they are been working awesome with that turbo. As the GT47 has a hard time keeping up with a 2JZ motor.
