HE341, 4in exhaust, Custom intake horn

[soggy]

Well my brothers and i have been doing a little work on the old beater. The first thing we did was make a new intake horn. Please excuse the horrible fabricating and welding, as its our first attempt at fabricating anything. We had a welder, cutting torch, cutoff saw, and a few grinders to work with. I didnt take too many pictures of the building process but I'll include what i have.

Here's the finished product, except for paint.

The next thing we did was mount an HE341 off of an 03 cummins, had reclock both the compressor and exhaust housings, plus drill out two studs on the turbo flange, it wasn't much of an upgrade, wouldn't recommend on and intercooled model unless you can get it really cheap, or free as I did. it would probably do pretty good on a non-intercooled since they have a smaller turbo.

Then we fabbed up a 4in downpipe, exhaust and flange using pieces from my brothers stock 6.7 exhaust, some 5in pipe i had, and a 6in tip, because of the tight fit by the transfer case and the limited pipe we had, I ended up running it out just behind the cab. I don't think it looks too bad, but it is temporary. when i get the money im planning on getting a real 4in downpipe and stacks.

The gains i saw from all this were as follows: Egts dropped from 1600+ to 1400 and take longer to get there, boost went from 20 lbs to 30lbs, much faster spoolup( might have something to with going from the 21cm housing to a 9cm) a mean turbo whistle, a much deeper manlier sounding exhaust note, and slipping torque convertor

Now i'm wondering about possibly having some intake horns built ( by a fabrication shop not by me) and want to gauge the interest, haven't got any prices yet but should have them within a week or so. I'll get a cad drawing with dimensions on here by Tuesday at the latest. I'm planning on replacing the whole intake plate on the next version, so it would be a bolt on piece. The dimensions on the intake itself would be 10 in on bottom, 6.5 in tall, 2in wide, 3.5 in on top, and either a 2.5 or 3in pipe coming in. It would use all the space in between the injector lines. Feel free to leave any comments.

Looks great!

I really like the intake.

Don't you have one of those turbos that you should be working on?

Fnschlaud4620 or me?

Hey soggy how is the EGTs towing cause really looking to go with a early07 turbo but was curious bout that because of the small 9cm2 housing.

[soggy]

I haven't towed with this setup, but my egts with the pump maxed and AFC lever missing can get to 1400, however this turbo is smaller than the one you're looking at. with your setup now you would have no problems with the 07 turbo, not so sure about the 400 horse you're looking for tho. It would make a good top turbo in a set of twins, which is probably the best route to go with a 400 HP tow rig. So I'd say go for it

Ok thanks just keep me updated on how it holds up, also you mentioned that you had to pull out 2 studs why exactly did you have to do that? Also how did the compessor outlet fit to the intercooler pipe?

[soggy]

well on our manifold there are 4 studs and the turbo came with 2 studs in it already, we made the turbo to intercooler work but it's not the best way, the best way would be to put a couple 45's on it, which i plan to do once i get a he351, let me know when you put yours on, i want to know how much better than mine it is.

[rattlebox93]

SOGGY are you running stock sticks? i was planning on putting a 351 on mine but decided aginst it because of the small housing. but it seems like it works for you but i wouldent think you could run much of a set of sticks with it and keep things cool or can you? any info would be greatly appreciated....also what did you do with the wastegate? did you block it off or what? thanks...dj

[soggy]

yep still running the stock intercooled, i'm not sure if it would work with bigger injectors or not, we tack welded the opening on the compressor side and wired the exhaust side shut, i'm still looking for a 351 to try it out. Anyone got one they want to get rid of for cheap?

[cedardiesel]

Oh ok got ya I thought you were talking about drilling out the exhaust manifold. By any chance could you show a better picture of the compresor outlet and intercooler pipe. Thank You

Hey Soggy found a 06 turbo for you on DTR here is the link

[soggy]

Here ya go cedar, Yeah thats a nice turbo but i cant pay that much right now. Had to loosen up all the clamps and pull them out slightly. It's handled 30lbs fine so far.

Oh ok I see what you mean about needing a 45 degree elbow. but yea I'm in the same boat with you about not being able to afford it otherwise it would be on its way to my front door but figured I would mention it.
