Engine/Transmission (1998.5 - 2002) Yet another 'what turbo' thread

[Froadin]

Ok, researching a turbo upgrade.

I have the HRVP44, and it runs good, and smooth (very little lope at idle, but nothing while actually running).

EDM 1. 5 sticks, and a Comp, but I didn't tap the wire again after getting the new pump.



Ok, two things, I tow, and I tow in the hills a lot. And I want to keep my exhaust brake.



I want a usuable setup, power for playing is fun, but the real reason of the truck is for towing, so it has to be USABLE power.



Obviously I would love a twin turbo setup, but I don't have the coin for that anytime soon. Although I would like to keep that option open.



I like the idea of a 35/40 hybrid setup that I keep my exhaust brake, minimal changes, and it should still be pretty close to the rpm range I have now, just more boost. I just worry about it not being enough air to keep my setup cool while towing.



Ok, the B1 can have a 35 exhaust housing, but this turbo seems almost like old school. Plus the cost is a big jump up. Just seems like a bigger turbo being choked off on the exhaust side.



What other choices do I really have?



Besides swapping to an inline exhaust brake (read, more $$$).



Or, get something with a HX40 exhaust flange style band clamp and run the newer Jacobs exhaust brake. More money because I buy a turbo and half of the exhaust brake (the brake itself will work with my current wiring/hoses).

One day i would like to build a set of twins with an exhaust brake in them.

Whaddaya mean by coin?



How much are you gonna spend on a hybrid? I'm sure for that cost you can utilize your stock turbo and an inexpensive HT3B for your twin set up. The HT3B is $500. 00 brand new.

 

[bmoeller]

I would check out www.htturbo.com or www.industrialinjesction.com They both have some options for you.



If the HTT turbo that is coming do the trick for me, I'll be doing twins. And I'll put my HX-35 on top, with either a S400 or HTB3 on the bottom.

LOL



Man you can't believe how much I have thought about this. My Banks brake elbow is pretty close to resembling a twin set-up hard pipe. I have often thought about trying to modify mine. I was at one time thinking the hard pipe would likely need an external waste gate controlled in concert with brake operations and boost pressure requirements. But that just seems to get way to complicated.



In the end fear of the unknown, downtime, complication and the cost has always stopped me from starting this project. I had hoped someday that some one with more resources and know how would attempt it. A market is already present, but sales would only emerge if it was more or less affordable.



For the future I was thinking that at some time some one would mod a VGT with a exhaust brake feature ( like the 07 Holset) that could be bolted up to a 2nd Gen. Probably would required turning the exhaust manifold over to droop down like in the 3rd Gen's.



My apologies for the hyjack, good luck in your turbo search. I have been looking around for one for my truck for some time. The best option I can come up with is a 34/40 hybrid or possible the ATS2000 or a B1 that has a HX35 flange.

Olee, NoSeeUm,



Check out TDR member robertyokes 500 horse B1, B2 twinset with the pacbrake in between. Nice.

ThrottleJockey, Yeah, I am not beyond doing all the work for making twins. I figure a set of studs, and 45 to 50 psi should make for a very nice towing setup. Of course I am not sure I have enough fuel with my 1. 5 injectors. I would think the cost would be about right, but wonder what the parts list would be like.

I haven't really looked, is there any GOOD list of parts needed for twins?



For everyone else, I am not sure the 35/40 hybrid would be enough air for me. If it would be, I would definitely just go that way and be DONE with it. But I have a nagging feeling that it will not be enough air to keep it cool while towing under full power.



Opoole, why haven't you made a twins w/ brake yet?

I had always considered it, and figured I would get an inline 5" brake, and put maybe on the downpipe itself. But having one turbo mounted would make that part simple, and keep the brake away from the elements, etc.



That link for the brake w/ twins is for a 3rd gen, not sure what I would need for a 2nd gen.

 

[ThrottleJockey]

Those 1. 5 sticks will turn a set of twins WHILE TOWING in the hills with the help of the Comp fueling box.



Anything running at 1200 plus degrees will turn a mild set of towing twins. Remember how a fueling box works. A lot of guys put in a set of injectors that are too big to tow with, then they blame the turbo. Towing will make a set of injectors seem bigger than they are with the issue of the retarded timing and the extended fuel pulse from a fueling box.



A fire truck is nice but a garden hose will fill a swimming pool. Eventually.

I may be the only one to recommend a hybrid, but I have nothing but good things to say about the Dodgezilla 35/40 and Jacobs Brake I have been running in my DD/Towing set up. In my truck with DD Supermentals and and Marco's ecm programming, I've seen nothing more than around 1200 or so towing (around 11,500#). The turbo responds well and seems to spool instantly, at least under load.



Now, add the drag comp to that combo, and it hits 1500+ instantly. But, with the 1. 5's and a comp on EZ mode, you should be fine.

 

[Froadin]

jgillot, don't forget to add in my HRVP44, which is like having the comp set on 2 or 3. I will ALWAYS have more fueling then just my 1. 5's.

Heck, I would LOVE to just put in a hybrid and be done with it. Cheaper and simpler. I just doubt it's ability to keep it cool.



ThrottleJockey, my setup now, with the comp on 1x1 and the wire untapped, while towing only 8k, I can get to 1300 FAST if I put my foot in it. Not sure how much past that it will go, I usually keep it below 1200 for any extended period of time.



I was looking at Rip's twin turbo kit. That looks like it keeps it EASY! I just don't know what it would take to keep the exhaust brake with that setup. The exhaust elbow that goes from the secondary to the primary looks pretty close to the e-brake in size and shape.

Anyone run Rip's kit? Looks like it really takes the trail and error out of it, while keeping it relatively simple. And I like simple for the pure reliability factor.



Side note, I wonder how well my setup would spool the twins running empty? Should do ok I would think.

Just curious about which size exhaust housing do you have? 14cm? Thanks.

I've been running one of II's HR VP's since they first came out. You're welcome to check my profile for the full rundown on that particular combo.

14cm wastegated housing.

 

[Froadin]

jgillot, ah, I didn't look past your sig line.

But I do want to run more power towing tough.

Question, the 450 hp you have, is that the comp on 5x5?

What temps do you see with the comp on 1x1 towing heavy in the hills?

Yes, that dyno # was on 5x5.



I really can't comment specifically on towing with the Comp. All of the towing I've done has been with just the injector/CaTcher combo. But with that considered, I have a hard time pushing it above 1200-1250 under load unless I do something really dumb. Now remember, we are only at a few thousand ft. elevation here. I'm not sure how that set up would work when you get up into much higher elevations.

 

[Froadin]

Yeah, elevation plays a part. I live at 3k, the first 'hill' is 7% and 4k+. Not too bad, but it goes up some where I go into OR sometimes. I also go into the sierra nevadas, and there are some good hieghts there.

Nothing like CO though. I figure if I could get someone from Colorado with a setup similiar to mine, and see what they did to solve it, I would have my bases covered.



It's hard to compare when you have the catcher program on your truck.

I wouldn't plan on towing with it on 5x5. Before the HRVP I like to use it with 2x2 or 3x3 for decent power. But could easily turn it down if I needed to with a touch of a button.

I would rather have it be able to tow AT power for almost anything up to 3x3 (or more if possible) on the comp.

The dodgezilla with the larger exhaust side would seem to be pretty close, but I hate the idea of wasting time/money.

Yes I have, at one time I was thinking of building a set of Rip's twins and ordering an extra hot pipe to mod the exhaust brake into. Then swap out the hot pipes when I got that part done.



That area under the hood gets so busy just with the twins. I think you might need to remove or relocate the right battery and change the twins piping configuration.



Jim

 

[Froadin]

I could live without the battery being there.

And it looks VERY cramped there. But that elbow sure looks close to the brake for size, etc.

Another point, I wonder if any single brake style would work better with the twins? Be it performance, or just the size/shape of it so it will actually FIT!
