Engine/Transmission (1998.5 - 2002) Htt - H-charger 60/14w

[NoSeeUm]

I was surfing the HTT website and I found the H-CHARGER 60/14W turbo.

H-CHARGER 60/14W Stage III quickspool hybrid HX35/40W HOLSET TURBOCHARGER 325-425 HP

60mm compressor, 14 wastegated turbine housing. NO downpipe required

91-2002 P/N 3590708 $985

Seems pretty close to the Dodgezilla or some of the PDR 35/40 series.



Anyone running one?

Similar, in that it is a HX35/40 hybrid. The DZ uses a larger wheel and the PDR uses a smaller one. Smaller wheels typically = better low/mid (towing) performance.

When you say wheel, you mean compressor wheel size right? As opposed to the turbine wheel size?



Jim

 

[PC12Driver]

Correct. I think the DZ uses a 62mm and the PDR uses a 59mm. The DZ works great when pushed hard, but lacks a bit on the bottom (from my experience). When I talked to the PDR folks, they said that they stopped at the 59mm compressor to keep the quick spooling characteristics of that turbo. Granted, there's more to it than wheel size, but that should give you an idea of what to expect.

Yeah I read some of your past comments about towing and the 14w DZ. In my case I want to keep my turbo mounted exhaust brake.



I would like just a bit more air so that I can feel good about installing some M1's. I like my set-up currently and I don't want to backwards trying to improve something that is already working really well.



Now that last part sounds dumb even as I typed it.



I am really looking for a turbo that spools well in the low to mid RPM range. The 14w DZ might spool at too high an RPM for my liking. My truck will unlikely ever be on a dyno or do any racing. I am beginning to think maybe a hybrid with a 12w turbo might be the best fit for me. Maybe keeping my stock 12w turbo, possible porting it a little and adding a bigger compressor to it. Drive pressure is my main concern with this set-up.



My driving style while pulling is rarely much over 60 mph. So this is where I need the turbo to perform best at. I have even thinking about a bigger intercooler, which effectively can make the turbo perform like it is larger.





At any rate, I was just wondering about the HTT hybrid.



Thanks;

My DZ 14 spools as good as the stock HX 35 it replaced. Perhaps the port matching compensated for the larger pin wheel. It's really exceeded my expectations.

After having towed with a couple s300 variants I have a hard time believing that a DZ with a WG14 housing doesn't tow or spool well. JMHO

 

[RonA]

I have tried a number of turbos and a DZ does extremely well with towing chores. I prefer it over the small S300(57-60 mm inducer). The little 300 that I tried (Bell WSB 57mm/. 7 housing) seemed to make boost quickly, but was doggy untill about 20psi.

 

[WShupe]

The DodgeZilla turbos use a 7 blade 60mm compressor wheel from an HX40. The Pier's version uses a 7 blade 58mm compressor wheel also from an HX40. In my opinion spending over 9 bills on an HX35 doesn't make sense.

to hybrid or not to hybrid?

NoSeeUm - I'm right there with you. Even with my mild setup, I really have to keep an eye on EGTs when towing - grossing 17-18K. I too am considering a hybrid because losing my exhaust brake is not an option and upgrading everything after the exhaust ports is a really expensive option.



Granted, there are much better turbos, for the money, available, but factoring a new exhaust brake in too, puts that upgrade out of reach. Might as well get a new exhaust manifold and exhaust system while you're at it. blah



Intercooler upgrades for the 24 valve 2nd gen are not common. You can get one, about the same price as a turbo.



Water/Meth injection sounds promising from the aspect that it kicks in only when you need it, but I just don't want to mess with the complexity - wires, hoses, switches, solenoid, pump, tank, injector, not to mention refilling it.



So I keep coming back to the hybrid idea. Industrial Injection will make a hybrid too, though I don't know the specifications, like compressor wheel size. Basically, I'm still looking for a justification to go that route.

I just got off the phone with Rip. I have a set of M1's coming. He said that a DZ/14w would work pretty good for me with the M1's / TST. But after some meandering on my part about spool up and EGT's we decided to go with the stock HX35 for a bit. If I can figure out how to get them in, I am going to sit at this mod level for a bit and see how it works out. Rip also suggested I up my waste gate pressure just a bit. It currently peaks at 30 psi, but settles at 23 psi pulling grades.



I will probably not go with methanol injection either. I saw one installation on PaulB's truck. He did a nice job with it. But for me, there is not much sense in messing around with it. Basically, I don't really need the power in the first place. I really think all I need to have removed are some testosterone injectors.



I see some intercoolers in the $700 range. As far as intercoolers go, I believe that I have a pretty good spread sheet for calculating density ratios. Thanks mostly to DieselFreak and some other fellows over at NWBombers. In essence, the intercooler makes your existing turbo larger. Calculating density ratios, you effectively get 50 - 150 more CFM for the same pressure ratio. This is assuming that you get the 25% increase in efficientcy the manufacturer is touting. Normalizing this, it means your boost pressure will drop 2 - 4 psi for the same engine RPM. In theory anyways and the whole concept is probably a good argument for diminishing returns.



Depending where I end up, I might have to cash up for a DZ or go with a modified hybid compressor mounted to my existing turbine. Maybe I might just be happy with where it is at.



Thanks for the interest.

the dodgezilla i had from city diesel had 6 blades and i was told it had a 62mm wheel. i was told it is the same wheel they use in their stage 3 hx35 upgrade. when i was looking into them city diesel said you could have the wheel in either a 6 or 7 blade wheel. i liked the dodgezilla when i had one. richard

 

[WShupe]

I have dealt with one HX35/40 from HTT, it had a 60mm 7 blade compressor wheel which is the same as their Stage 3 Upgrade. They also have a Stage 4 that has a 60mm 6 blade compressor wheel. The 7 blade 58mm and 60mm compressor wheels are Holset, the 6 blade 60mm compressor wheels are Schwitzer.

The compressor wheel on my DZ is 62 mm & you can count the number of blades yourself.

The HX35/12 is a great towing turbo. Mod the wastegate to get all six to dump and call it a day. That should be good for about 350hp as long as you keep boost below 35psi.



I'm a fan of being able to leave the truck in 6th with the cruise on and not have to worry about watching the pyro. With the 35/12, I can do that (with really steep/long hills - like the ones in Colorado - being exceptions). The DZ/14 needed about 2k rpm to stay cool (over 70mph) and the HTB2/12 needs about 1800-1900 rpm (65-70mph). Anything less than that and the pyro twists up faster than the boost when the grade increases.

My DZ from the side.

 

[RonA]

Your first picture was the turbine side, not the compressor side.

I see you are correct. Forgive my error. This one seems to have eight full size blades & eight short blades between them.

Yeah... . I am going to try it out. You are talking about the exhaust manifold to turbo plate, like the one Rip sells?



You done any work porting the 12w?



Edit: Nice picture Darkhorse.
