HE431V vs any other turbo

[deerslayer1979]

I need my truck to tow better and next on the list is a turbo and exhaust. Truck is a 92 W350, NV4500, 4.10's. Pump has been tweeked a bit, turned the fuel pin, lowered the star wheel, adjusted the smoke screw, and swapped on a 16cm housing. Runs 30-32psi boost, and will hit 1300 pretty quickly with a load on. I would like to get into the 300hp range someday so big enough is a concern, but so is money. I have been looking at a couple of OEM turbos, just not sure which one I want to go with. Let me know what you think the pros/cons are of each and any other ones you may be thinking.
HX35/HX40 hybrid
HE351CW
HX40
HE431V (non VGT)
Cat C7 250HP turbo
I plan on 4" exhaust at the same time so thats not really gonna be a concern.
Thanks,

For only 300ish HP i would go with the 351 or the HX40. Either one would be much easier install the the 431 and could easily sustain 300 HP.

Why no VGT? Gives boost over a broader RPM range without over spooling the turbine.

I don't want to deal with the controls of the VGT. My truck isn't a toy at this point and functionality trumps anything else.

Controls are easy on those, lotsa guys have figured it out. Just run the vanes off the drive pressure.

Pete- please elaborate on the VGT controls, or tell me where to look to do my own research. The HE351s have gotten pricey, but I can probably get some 351VGTs or a 431VGT pretty easily. Lots of tractor and truck junk yards just south of here.

First off HOW do you want to control it? Fleece is suppose to be coming out with an electronic controller, was to be relesed in March and still isnt out to my knowledge. Mechanical control is EASY, I have a wastegate actuator that will push the exhaust open when it builds boost. I am using boost pressure to open it, some are using drive pressure. The exhaust brake I do not have done yet, it will be a linear actuatorwith a switch on the brake and a switch that I can operate with out the brakes, those will be after a master power switch so I do not have to use the brake at all if I chose not to.
My 351ve has been on about 2 weeks now and I am really happy with it, it took about 6 hours total to get the brackets and actuator built and dialed in. Its not perfect yet but close, havent towed yet but will be going camping this weekend, hauling a 24' trailer with quads and a camper so truck and all should be about 20,000lbs.

I can send you some web pages I have on how to manually control it, there are MANY out there. IMHO it is a VERY worthwhile upgrade while they are still fairly cheap to get.

And dont call me Pete >;)

[PToombs]

Now I'm insulted! Calling you Pete would be a complement IMO!

Dan, I'm going to see one on Sunday, my buddy converted his FRT (funny round truck) to one. He said there are lots of vids on you tube and Comp D of them.

I'm interested as well. Since you can snag the HE351VE's for cheap I would go that route. Please post the links up and get back to me about how it tows. BTW how much do you have invested in your setup, figuring the turbo cost $125 shipped?
Thanks,

Here are a few links, there are more links in the threads to other builds. I am NOT a good example of how much money I have into this turbo, M&H made me a great deal for letting them use my truck to mock the turbo and adapter up, the turbo itself was given to me by a buddy who works at a dealership and the wastegate actuator and 4" mandrel bends and turbo exhaust clamps etc I had "in stock" at home. If I were to hazard a guess Id say a guy would be into it under $750 installed if he did his own plumbing and hung the turbo, built the brackets etc.

I will keep you posted on the towing but after filling up again today and seeing my 20+ mpg back and not being able to get my EGT's over about 1175* Im sure it will be great.

I'd like to find one for $125 shipped. Most of what I've seen has been $250 and it's going up as guys realize how good they are.

Yep, and it would only cost me $65 to ship it to my door! I sold my other truck tonight , so I have about $600 to get a turbo and exhaust onto my truck. I am now on the hunt for a cheap turbo.

He has shipping quoted at $26.82 so thats all you should have to pay to ship it. Like I said its a very worthwhile upgrade IMHO, cheap and while I havent had it to the dyno yet I know it makes more power, lower EGT's seems almost to good to be true!!

[deerslayer1979]

When I looked it had a "calculate" link in the shipping area of the page. Told me it was $65 to ship it? Maybe I looked at it wrong, but I didn't see the $26.00 quote for shipping. I will be calling the local dealers tomorrow to see if they have any they just took off. May even try some of the big truck shops to see what they have. The cheaper the better at this point, I would really like some new sticks if at all possible.
