Still in the process of shopping for a new turbo, I found this info about the Holset Hx-35/40 hybrid( I also found compressor maps for the Hx-40's if anyone's interested)...
Compressor
2.362 inducer
3.328 exducer
Turbine
2.753 inducer
2.364 exducer
Here is the specs on a straight Hx-40...
HX-40
Compressor
2.362 inducer
3.328 exducer
Turbine
2.995 inducer
2.480 exducer
Here are some specs from a Precision Sc6152 rated at 630hp...
Compressor
2.416"ind.
3.227"exd.
T350 Turbine (Stg 5)
2.920"ind.
2.420"exd.
Basically, the compressor is slightly bigger than a 60-1 but slightly smaller than the 61mm (gt35,t-61,sc61 etc.) but of course includes the Map width enhancement grooves in the compressor wheel supposedly making it about 10% more efficient than a compressor of similiar size. The Hx-35 turbine wheel is bigger than a stg 3 wheel but smaller than a stg 5, I guess a perfect stg "4" if there ever was such. The Hx-40 turbine wheel is bigger than a stg 5, and also slightly bigger than a p-trim.
Basically with all this being known, I would say the Hx-35/40 is a very attractive alternative to the 60-1, gt35 family, or anything else that uses the 61mm compressor. I would probably rate it's max potential between 620-660hp. The Hx-40 on the other hand I'm now thoroughly convinced it CAN achieve up to 700hp, but nothing more.
Basically...I've pretty much made up my mind that an Hx-35/40 hybrid is going to be my next turbo
Pretty sweet considering they go for $799 brand new.
Oh yeah...I hope this actually potentially helped somebody :lol:
