Ah, that's right. So what turbine are they putting into the 400's?The GT50 turbine is 91/99mm.
We have ran 4 different gt50 based Precision turbos without one problem. From 1160 to 15xx fwhp. I have been told by a reliable source that precision uses a chinese gt50 tw. I think it's an awesome middle ground wheel. We ran and tested it in the 1.08 and 1.39 AR housing.
How it performs stuffed into an s400 ex housing I dont know.....
All singles btw. Two clipped versions, 2.6 mwe, and a 3.0 smooth. Also ran a 76mm version for 3.0 smooth. Then ran a PT8891 that engine dynod over 1500 on one pass. Later dialed that tune in via data logging on the track, so I'm sure it was more later on.What compressor wheel are y'all running?
Genuine borg 96 is tried and true, whatever fi is stuffing into a borg cartridge “102” is most certainly and aftermarket turbine wheel. Not bashing at all I personally use Jose’s products, just fyi
There's alot of 6 and 7sec 1/4 cars running his stuff. It's difficult to say, seems alot of guys running his GTR builds and of course the ETR.

I have never seen nut hugging on the level you are at.
Wipe your chin. :hehe:
Garrett thrust bearing is crap.Forced Induction and VS Racing offer the gt50 turbine s400. Has anybody done a back to back test in a compound setup?
How do the thrust bearings compare between a gt50 vs s400? Would one be better off to get a gt5018 or s488/102?
As long as the turbine creates enough shaft power to run the compressor the affect the design difference has on power is minimal. Certain turbine designs will run much more compressor for their given size compared to others, however this is typically only important in cases where there is a turbine size limit.
Below you can see a graph comparing drive pressure for several turbine wheel/housing combinations, these are only a few examples from that test which included over 15 combinations in total. Across the board with the same compressor inducer size the overall power differential between any two turbine configurations was less than 4% in total.
