hybred holset hx35/hx40

[efrainz28]

I'm just wondering how it preformed?? I would like to have little bit of both worlds. Thanks

FYI I searched but I didn't find any info. I just found HX35 vs. HX40 topics


Mod correct my misspelling. I misspelled hybrid. Sorry

 

[black_gst]

im thinking of running the same turbo... it just a hx35 with a hx40 comp wheel. i have read that the boost hits harder instead of being a bit smoother compared to a regular hx35

This is what I know: you have to have a housing and wheel from a HX40. The turbo need internal modification done to it. You get more flow than a stock HX35 but not enough as a stock HX40. You get faster spool and have a stronger shaft than HX40.I can't find any flow difference or hp gains going from an HX35 to a Hybrid.

This is something I would like to know, did you look through the Holset turbos thread?

 

[black_gst]

well i can get either one with whatever a/r i want in a T3 flange for $600 brand new

Yes I have, thru 1-5 part and I jump to 7-8 part (a lot of reading) but I haven’t found any real data on the hybrid. I also read on diesel forums about them but they mostly say there EGT are lower and towing is easier. I know diesel engines are a different animal.

The shaft structure, metallurgy, and diameter is the same between the hx35 and hx40.

The real question is whether or not the stock hx35 turbine housing flows plenty to merrit the hx40 compressor. Running an hx40 compressor with the bolton housing with an hx35 turbine wheel is rather pointless.

PM me your exhaust housing choices for a HX35 turbine wheel.

i copied this from a different site but i want to share this info
</div>I know that for a fact because I put a H1C shaft in a HX-40 housing a and now my 14cm W/G housing bolts right up. The only diff in the HX-40 shaft and exhaust wheel and the H1C, WH1C, and HX-35 ( all 3 use the same shaft and exhaust wheel which is friction welded so it is one piece) is that the exhaust wheel on the HX-40 is 5MM larger so even though it has a 4&quot; outlet were the gasses pass threw the wheel and out to the flange is only 5MM larger than the others. So that 4&quot; outlet that every one thinks is so great about the 40 only really amounts to 5mm diff. But you gain much more flow on the cold side and lower temps at the same PSI vs. a 35.<br />

heres the rest<br />
<br />
Nut and shaft were in air filter compressor pices were in intercooler.<br />

<br />
this is your HX-35 This is your HX-35 when your W/G sticks shut and boost goes some were over 55 PSI<br />

the Omni trans busses out here that are CNG powered do this all the time... they over spool and the compressor wheel explodes.

the turbo place i use rebuilds these all the time for them. i walked in one day and saw like a dozen hx35's

so how would this turbo work?

i would love to know how one of these hybrids perform with the stock housing and a twin scroll mani. i know the hx35 spools very quick and is nice in twin scroll mode but im curious to see the kick from a hybrid and twin scroll

Not well. You're going to be limited to what the BEP HX35 turbine housing can flow, which is somewhere below 55 lb/min. It doesn't matter if you have an 80 lb/min compressor- you're only going to make as much air as will pass through the turbine housing and wheel. The rest will just be added lag.

When you say limited what exactly do you mean I know that the A/R is .55 but when you say limited do you mean how much hp? Or airflow or both?

 

[JusMX141]

Airflow = horsepower.....so both.
