I get full boost (22psi) around 4200-4300rpms

Did you get this h1e from goldfarb and associates? What part number do you have. I have an h1e and I was wondering if the spool would be similar to the hx40. . . Looks like it is. Were you the one who bought the same h1e as mine?

It's possible. I don't know all the wheels for the hx35. I thought for sure that there was a 7blade 56mm wheel for the hx35. . . I have to look through my notes. It would be very exciting to have the spool of an hx35 but the flow of a 60-1. I'm not sure if the hx35 turbine wheel in the bep housing could push the limit of such compressor flow. But I can see the possibility with a good divided runner t3 manifold, stock holset turbine housing, and a wastegate dump tube.

Yessir, I got the same one as you. We talked in the the other holset thread...but it was like a year ago lol. I have this turbo on my automatic, and I just installed a nitrous kit to help for off-the-line stalling. We'll see how everything goes...

There is a 7blade HX35. I can even give you the Cummins part # if you'd like.

Anyone know which HX35s came with the Ti compressor wheel option?

Also, you guys are saying the it spools faster than the E316G, is that with the BEP housing or the holset? I would rather run the Holset, personally.

[95tzlgst]

thats with the bep .55ar

[turbotalon1g]

How would a HX35 in a bep bolt on housing with a T04B cover act? wouldn't this smaller cover limit the power potential?

u wouldnt take advantage of the extended groove then :P

[ludevtec93]

do they still sell these BEP housings? i cant seem to find any.. and do you guys know where i can pick up a hx40 for fairly cheap besides ebay?

This should help out with spool a little on my hx52 Funny part is though I have no idea how the hell the fuel rail would hook up

[AXRabbit376]

That thing is funky looking. Did you make it? Or what was it originally made for?

[ezz-e]

doer any one no if the oil restrictor that feeds the turbo on a 95 oil housing works to feed a h1c? i have removed balance shafts and no porting done to the oil pressure regulator

[projecTSI]

Is that one of Jake's ITB manifolds?

Well the fuel rail connects to the head not the intake manifold. . .

Ezz-e, you will need a restrictor that limits pressure to 72psi. I think any restrictor for a garrett JOURNAL BEARING turbo will work. As long as that restrictor size has worked with a journal bearing turbo and a 4g63 with b shafts removed. That is the subject I would research. I've never used the h1c with out b shafts.

As in the dsmlink thread, I suggest feeding it from the head. If contaminated oil comes from the head and blows your turbo, it already scored your crank.

Not one of, THE manifold as in the very same one he had on his car and went 9.5 It was made by him personally and then someone bought it off him for lets just say a shit load and they guy changed his mind put itup on ebay and here it is.

Dsm-onster thanks I forgot about that. I don't have a head here so I forgot how it hooked up on my 420a it went into the manifold. Should make for a sick setup

[95tzlgst]

^^ That manifold is nice... Do work son!!! lol

If you get ready to sell it, holla atcha boy.

I just dumped my goodies off at the machine shop. Should have a motor soon, then I'll max out the hx40.

Check out timsturbos.com for BEP housings

I can finally post here yay!

Here is that scan of a 7blade HX35 with a 12cm exhaust housing. You can see near the bottom I see .453KG/s worth of airflow, which means 59-60lb/m.

This might confirm that the Cummings chart might be onto something. Ill grab some compressor measurements and part numbers later today.

[dsm-onster]

From our PM discussion, isn't your maf scaled different than stock? Would this mean that your airflow is higher than actual? Like hacking, or removing the honeycomb for us dsm guys? Or was it the other way: the airflow is higher than what is calculated.

[darkhorizon]

I forgot to tell you that I researched that.

I have never really scanned g/s before, so I was unsure what the calculation was based on, but after researching that, we have a pseudo G/s output from the PCM, that you just have to crunch a equation on top of. That output is based on the maf map programmed in the pcm.

Either way, the way I have it
