Holset Turbos

[sleepydsm]

So, after a lot of reading, looking, thinking. I more than kinda want a Holset HX35 or 40. Should put my car right where I want it to be, and I like the fact not many people use them. But I want to hear from anyone anything they have heard, read, saw, experienced, or just believe about these Holset's.

One of the most common claims, and main reason people get, is "faster spool than their Mitsu or Garrett counterparts."

What makes a turbo produce boost sooner?

1) polar moment of inertia - probably not all that great on a turbo meant for a 350+ cu in diesel as the designers knew they had a LOT of high temperature exhaust mass to help get that turbine going.

2) a/r ratio. a conical nozzle wrapped into an exh housing. small ratios spool quick and reach choke early. this is likely why these turbos spool fast, if they even do at all.

3) a bazillion other factors

I dont understand the need to get a random redheaded-stepchild turbo to be different.

"wow your car sure is slower than my gt30R car, but props for being different!"

^wow.
Actually everything in the hundreds of pages of Holset experiment users say opposite of your whole post. Who is right? I don't know.

They are proving spool and better top end.
ex. HX40 in mitsu .55AR housing 650whp, HX35 in a bolt on housing 26psi 494/420.

I am thinking about the same thing, in a nutshell if you want 61/35 like power do the HX40, you want something with a spool comparable to a E316G (don't know how much I believe this) but with flow better than a 50 trim do a HX35.
You have options for .55AR mitsu, BEP T3 .70AR, or stock holset where people have cut the divider (don't know how effective) or are having divided manifolds made.

My choice is HX-35, but being budget minded I might have to pay some $$$ to make it happen. I want it in a bolt on with internal gate.
It would cost me $360ish for the exhaust housing, lines, gasket + holset itself.
I think these turbos are appealing because of the spool/top end, but also because of the durability of a OEM turbo, I am not knocking any other turbo here.
Hope that helps.

Make sure to buy other awesome Bullseye products as well, like those baller V-trims they used to sell.

^Maybe you should try something, last I heard you are still sub-par for power.
Maybe if you weren't on here being a smartass.

The V-Trim is absolutely amazing, but I agree, the HX-35 is pretty well suited for the 2.0-2.5L engine range.

I have a buddy who has a Merker XR4Ti 2.3l with a volvo DOHC head and a HX-35....the thing screams!!

People on tuners are shower low 11's on the HX35 and good power in the 400-600 whp range on the 35-40 with the shitty BEP housing. Assuming thats a fact, that isn't that bad?

There you go, talking shit again.

You calling anyone else a smartass is beyond funny.

My car makes great power for the boost i run :) Thanks for trying.

No one has said anything to prevent me from buying one of these. I can't make up my mind.

Super Bleeder are you only skeptical because you don't know enough about them? Where as we all know about the tried and true turbos. I don't know anything about the Holsets other than what I've read on Tuner's from the small group of people that have them. And they claim and are trying to prove that these aren't just worthless diesel truck turbos...

Well enjoy the good laugh, ITS THE INTERNET. :woohoo1: lol.
Also Kevin, I would say to try it depending on your goals for power and spool.
I know that I would try the HX35 because it supposedly spools quick, comparable to a E316G, one guy made 494/420 on a bolt-on housing at 26psi.
If you want bigger HX40, comparable to the GT35R sized stuff but again in the bolt-on housing it spools faster and has put down 650whp, though the power number i believe was on a stroker.
