Ive searched but most of the information I found was for the he351ve or the 60mm 431.

From what I have found it seems my turbo flows near 80lb/min which seems high to me. Any help or input is appreciated.

My He431ve:

Compressor:
- Billet MFS 7-blade
- 64/92

Turbine:
- 12-blade
- 67/76
- 29 cmsq housing

 

I'm hoping TheShodan will see this. And or anyone else knowledgable in Holsets.

I'm looking for any information about my turbo someone might have. Specifically flow, max efficient boost and anything else you might have.

Thanks again.

Tells me you may have some thing else.
According to this:

And 29CMSQ housing is way wrong b/c He341 and He351s are VGT/VNT.

 

The first link is for an he341, mine is a 431.

It's not listed on the second link either.

29cmsq is the max it can get, from what I have read the he431 also has a 19cmsq model. And yes it is VGT, not VNT.

 

It controls the area of the housing... not the angle of the gasses hitting the wheel... the 351 I have goes from 2cm to 25cm

431 is the same thing but I don't know how small the housing gets. Holsets turbos aren't true vgt but more vnt as the arm controls a slider that physically makes the turbine nozzle area bigger or smaller
