Holset HX-35W installation

[Daan]

Oh JOY! Finished installing The Holset with intercooler on my '85 6.2.

I had a cracked head, so the truck had a vacation anyways. Good time to do some upgrading.
The Turbo I used was a rebuild HX-35W wich came off a Dodge 5.9 Cummins.

see some pictures here (http://www.imagestation.com/album/?id=4054320093)

First results (measured on intake man):
Normal driving, 50mph, flat road 5-6 psi EGT 350
Stepping on it, 2800 RPM 12 psi EGT 600/700 then the wategate opens. IC pressure loss 1.5psi

More details comming up!

Way to go :D
Too bad you can't show us next week in Luxembourg :(

Sounds great. What fuel rate are you running? How much black smoke is there on acceleration?

In previous discussions on this board, an HX35W was mentioned as not putting out any air until one spun the snot out of it. I'm very interested in hearing you results.

Nice fabbing, and I dig the intercooler.

David, I heard the same thing which is why I went with the MHI. Nice to get some feedback from an actual user instead of just theory based on turbo size.

That is very similar to my setup. I run a WH1C with a 14cm wastegated housing. I also have a customized intercooler in front of the grill. Your installation looks very professional. Let us know what the future brings...

Thanks guys, great to hear you like it.
Peter, it sure is a shame I can't make it next week! Was really looking forward talking to some people who can appreciate our big, not so fast diesels ;)

Dieselboy, I can't really say what fuel rate I'm running now.. I'm only driving for a week or three now, and I really REALLY like my new sound and driving 'style' if you know what I mean. It wouldn't be a fare comparison with before. And the black smoke..well the only exhaust I have so far is the downpipe so I can't really see if it needs some more or less diesel. I'm waiting on some 4" piping so I can build an exhaust.

I also heard some things about this turbo like lots of backpressure, higher EGT's and not moving any air. Being quite stuborn I went along with it anyways. Just couldn't imagine this turbo not functioning on a 6.2. Sure, it's no perfect match but it works out great.
I did keep crossover piping relativly small, to keep gas velocity high by the way.

Next Sunday I'm leaving for a trip to California :D , So I won't be able to update those interested for the next two weeks. But when I'm back I can finally finish the job properly and give you some more details.
Thanks again

Very nice job! That turbo is capable of putting out over 35psi and when balanced and lightened it will provide 40psi, before backpressure becomes a limiting factor on a Cummins 6BT 5.9L.
