comprehensive data on HT3B
Can we please list known measurements on various HT3B turbocharger models.
A friend of mine bough HT3B off the Ebay. Seems it's larger than we expected, and may not be suitable for doing twin turbo setup. I am under an impression that primary turbo compressor inducer ought to be at about 70mm's (or below) in tow twins.
Appears to me that his turbo is suitable for high rpm/high hp engine.
Specs of his turbo:
Compressor wheel inducer 77mm
Turbine wheel exducer 87mm
Turbine housing 26cm²

The compressor wheel sounds a little big, but it should work. The down side is it will just take a little longer to spool. On the up side it will move more air.

Crickey!!
I read from a turbocharging handbook that the main governing factor to a compressor air flow is the inducer diameter.
I have , however, noticed quite a large change in air flow volume (mass) when comparing Garrett turbocharger compressor maps against one another.
The (somewhat) same diameter inducers can flow surprisingly different numbers.
Go figure.

Well, it IS the main governing factor, and a larger inducer will flow more IF the design is the same (same number, angle pitch of blades, etc). A lot depends on the trim. A lower trim wheel will have a larger exducer for a given inducer size. This accelerates the air more against the housing because there is increased angular velocity. Hence, a lower trim wheel will "suck" harder on the inlet for a given inducer size. That means it will flow more- to a point. That point is a near-vacuum at the inducer. Once you hit this point, it doesn't matter how much harder you "suck" on the inducer, it won't flow more. So in a sense, it you just hit this saturation point a little earlier (in terms of shaft RPM) with the lower trim wheel (larger exducer).
