So I'm looking at two Holsets I can buy, both H1D. They both have the same turbine wheel.

One has a 65 mm exd / 37mm ind. compressor wheel; exhaust housing critical area (whatever that is) 6 cm
The other has 65/41 mm compressor wheel, exhaust housing critical area 8 cm

I'm tempted to buy the one with the smaller housing, however about its smaller inducer—what does it mean in terms of power or spool?

thanks for any help.

 

600hp turbo

 

hmm doubt that, not with those small inducers. I'm just wondering about the power potential of smaller one, I like it—should have a quick spool.

 

C D E
C = quick spool, depending on exh will make good power
E = 500+whp with luck
I guess D leaves you with the best of both worlds? never seen one yet. pics nigra.

Also, both inducers sound SMALL get the bigger one.

 

If that is the true size even the big one is smaller than a 14b. A 14b is ~43mm inducer / ~58mm exducer.

Way too small to hassle with IMO. I couldn't say for sure especially without the turbine wheel size but it should spool slower than a 14b too given the larger 8cm turbine housing of the bigger turbo.

 

Yeah both seem too small.

These pics are all I have



slightly smaller H1D:

 

Buy my remanned HX35 and be done!

 

You're too far... I'm in Europe

 

Gay! International Priority wouldn't be too bad. Maybe $100. Still worth it maybe? Cheaper if you want to wait 3 weeks, but then it has to go through a bunch of sorting facilities which raises the chance of it getting damaged during transport. That's why fast shipping is a good choice; international or not. IDK how available the HX35w is in Europe.

 

its such a common turbo surely he can find one somewhere. Especially with the way diesels are so popular over there. H1C's are even more common than HX35's around here.
