Holset HX35 - Flow Chart

[Billman]

On the hybrid hx35/40 and the 2 super 40 I have the compressor side is the same. All have the 7 blade 60/85 compressor.

What diameter do the housings measure ?

[Billman]

On the outside? I had to use a spacer approx 10mm (can't quite remember) for it to fit with the k26 housing on a stock rs2 manifold.

[ian4455]

8 blade, 54/81 on compressor wheel. diameter of housing is approx 180mm. Hotside is kkk with 60/70 turbine. 8 cm3 volute.

That looks good, but I'm wondering how restrictive the turning housing might be.

Just wondering if any turbo experts on the forum could advise.

[Billman]

Very nice. It will be enough for 450hp maybe a bit more. Where did you get the housing from?

[ian4455]

Housing is HX35 the smaller option available.

[Billman]

I mean the K26-8 turbine housing.

[ian4455]

Sorry should have said K26-6 housing.

[Billman]

aha ok. Still calculate with 450+ with this combo.

What could a stock HX35 56/82 60/70 mated to a no 10cm3 hotside produce ?

Ian, all anyone would tell you is speculation. I thought that a 0.70AR would be ok for a SuperHX40 in regards to spool and it turned out to be horrible for my taste (4600rpm for 1.8bar on 3d gear).

If i were to use a holset again and would like the midrange, i would go for the smallest hotside possible and not worry about the final hp figure if using the HX35 or HX40 in a hybrid form!

[ian4455]

ok thanks, still a lot to learn so putting the feelers out for advice.

My car's going to be off the road shortly for further upgrades, so considering options even though i may not fully understand everything.

probably spool a bit later than the K26 housing and will produce a bit more.
