HX35G Specs?

[JaxonsGSX]

From what i can find there seems to be some discrepancies to whether the HX35G(7blade) has the same 54mm inducer as the HX35W, I hear its possibly 50mm?
Im thinking of buying one soon, and i would hate to end up w/ the smaller of the two.Ive done a TON off searching on the interwebz but cant find any real info. Any concrete info would be much appreciated

If you're hoping to get a 54mm compressor, don't get the hx35g. I had one in my hands a couple days ago and wound up with a 49mm compressor. I don't have any compressor maps and can't say how well or poor it flows compared with the conventional compressor wheels found in hx35's, but if you're after the 54mm, try to find an hx35w off a 5.9L Dodge Cummins. After calling Holset and some of their distributors, I found that hx35's have a large variety of compressor wheels, depending on application. If you get an hx35 off the cummins, you know for sure you are getting either the 56mm 8-blade (94-98.5) or the 54mm 7-blade (98.5-02).

Yea your posts in the Turbo Tech forums was one of the reasons i was so concerned. I can get a sweet deal on a HX35G right now that's why I've been trying to find some real info. Thanks.

Its probably gonna be about a 48-50lb/min turbo. Right around what a 20g, green, 50trim is. You can make 450+whp on E85 with it, and it is a perfect mate to the bep housing.

There were some HX35G's out there with a 6cm (yes, 6cm) T3 single-scroll turbine housing. Wondering if this is possibly the bastard with the smaller compressor; all other HX35's I've seen had at least a 54mm compressor inducer.

 

[JaxonsGSX]

Yea the one I'm looking to buy has the 14cm turbine housing, so you would THINK it would be the 54mm compressor. But it seems you just cant be sure with these things

 

[talonDSMerr]

For what its worth, the one I had also came with a 14cm2 divided turbine housing.

 

[bastarddsm]

Do you want to part with that 14cm housing?

 

[talonDSMerr]

Sorry, I returned it to the seller already, it was falsely advertised. I'd PM Justin, he might have some 14cm housings laying around.

Are you looking to mate it to an hx35 with divided manifold? What's making you pick the 14cm housing over the 12cm housing, if you don't mind me asking?

 

[JusMX141]

No 14cm housings; lots of 12cm's though. I had a 18.5cm up until recently; it went cheap as a test subject for Mr. Peepers' setup.

 

[bastarddsm]

I have a 20cm mated to my 58mm 8 blade, on a semi divided manifold. So naturally I want a smaller housing for better spool. It seems that several have seen the 12cm to be a restriction at about 30psi or 550whp on E85. I figured that a 14cm would be good. I was just gonna order a new NON WG one from HTT, but they are $295. I'm hopeing to see ~ 600whp @7500+ with that. I made 460whp at 6500and 25psi with delta 272 cams and a stock IM. I'm building an intake, so that should help. Plus I"m experimenting with a wicked sweet boost control technique that should help the high rpm power a lot.

 

[talonDSMerr]

I know Mr. Peepers' setup sees a dropoff in power at high rpms but is that due to the 12cm housing being restrictive or due to the 264 intake cam? Did the other setups you mentioned include using a divided manifold? Or were they open T3 manifolds with the stock 12cm housing with the divider knife edged?

The 14cm housing seems to be the one in demand by the diesel guys too, as its marked up considerably over the other housing sizes. Gillettdiesel has the non-wastegated 14cm housing for $285. Its not a lot cheaper but, hey, you save where you can. I got a non-wastegated 12cm housing from them and their service is terrific.

Post your build thread when you have the time, I'm interested in seeing what you can do with the 14cm housing and what kind of wicked boost control you're planning on using.

 

[bastarddsm]

I think peepers fell off becuase of the 264 cams, and the stock IM, but he didn't see as much gain from going to 30psi from 25, as he did 20-25.. Almost all the other guys running em are a single scroll T3 12cm setups. Richard33, Bwhite, Rampridersrider, all plateaued at about 500-550whp. They all have various I/M combos.

I need to get with peepers and see how a 18.5cm housing spools with a real twinscroll. IF its decen't I may just Keep my 20cm, and build a good TS exh mani.

Right now at my boost and such, the typical airflow calcs at 6500 rpm and 100%ve say I should be moving 44.1lb/min. Logging my IDC's and AFR, I calculate I'm moving 46lb/min. Trapping 121.85 @3350lbs is 460whp. So it seems that my setup is doing pretty well being more than 100%VE and getting 10whp per lb/min.

Anyway, I'm just down the road from you about 45min. we'll have to get together at byron or cordaova or somthing.

That makes me think the backpressure at those levels of boost starts becoming a problem, too. Either way, more and more people are beginning to run the stock exhaust housings over the bolton BEP ones, so we should be getting more data onto the forums in the near future.

I'll be heading to Byron once it starts getting warmer to test out the current setup. By the end of summer, I'll hopefully be finished stroking a spare motor and be able to drop that in. I'm bent on building a setup with gobs of bottom-end torque for street driving.

oh god a stroker with a TS HX35 would be trans eatin monster.

Just remember: Smokey Yunick was wrong, Horsepower wins races, torque destroys DSM transmissions.

 

[talonDSMerr]

I'm hoping using a divided manifold with the divided housing lets boost come on earlier and power to come on more gradually so the shock is less on the drivetrain. If not.. maybe I'll pick up an 18cm housing before all is said and done.

I'm not building a drag car and torque is a lot funner than horsepower on the streets. That's why Honda's generally suck...
