Re: hx40 hp?
HX40, HX40W and HE431 run close to about 70lbs/min at 3.2PR.
That means that maximum efficiency for use of that turbo is about 31-33psi of pressure. for 70lbs/min to be effective that's a bit over 600-700whp maximum. Doesn't matter if you're an LS/VTEC or a 383 stroker v8. the turbo can flow only so much. Some variances include which turbine housing you're using such as either 12cm^2 or 18cm^2. No one can guess your exact hp from this, but this is about the range you'll fall in, provided you have the correct supplemental components to aid in that kind of power

Re: hx40 hp?
Now, when it comes to rebuild or replacement of any components, that's a different story. You'll be more pissed off than ever, when you find you can't rebuild the damn things very cheaply or easily.

That's what I was thinking, rebuild kits are all over ebay or you can get 'em at the Dodge dealer. I've had Holset apart and it was 1000% easier than the IHI turbo I did.

Re: hx40 hp?
The ones from the Dodge dealer for the Cummins have to be machined to fit some of the other HX series wheels. Ask how much they want for a compressor cover or turbine wheel. Only then will you **** your pants at the price. (At least from what I recall)
When I say rebuild, I don't mean just some internal bushing kit. I mean THE WHOLE REBUILD. You're better off finding another used one. Just letting you know.

That's because 99% on ebay aren't the real parts (though most of the younger people don't care), and you're not accounting for replacement damage to wheels, shafts and housings. So go ebay if you must, but buyer beware. The IHI turbos are a b!tch to rebuild if at all. Especially the Subarus.

Re: hx40 hp?
Hehe..Alright, no more of HP expectations, I'm not much of a Holset fan. I may know a bit, but I'm no encyclopedia for them. different housings will give different results on similar types. They all run within the same family.
HX30,30W/HY30/HE300 - 35lbs/min range
HX30,30W/HE300 - 33lbs/min range
HX32W/HY35W/HX35/35W - 55lbs/min range
HX35,35W/HX35/40, HX40W/ HE431 - 70lbs/min - 80lbs/min depending upon turbine wheel and housing.
and a billion others.

Similar to HX35, about 53lbs/min-56lbs/min

Re: hx40 hp?
No worries. I get an average of about 15/day. I never mind helping, but when its just questions of XXHP for XX Turbo with no additional input, it gets a bit gruesome. I'm not a vending machine just spitting out a can of answers based on a button, ya know?
