So what happens later on down the road with all these performance upgrades? I want to try and keep my truck as long as I can and get as much life out of the engine as I can. I understand the whole pay to play thing. I would hate to mess up an already great packaged truck in hopes of more power. I would love to run twins but I don't sled pull, drag, or tow. I can't seem to get rid of my tiny HY with out someone tellin me I will have EGT problems. From what people have told me the only answer are twins. Is it possible to upgrade with out having to get twins to keep EGTs in check? So how do you guys do it? Can you guys set me straight? Whatever you guys think let me know

 

You definately don't need twins to keep egt's in check.......there are only a small percentage of guys here that actually run twins.......don't get me wrong, I would love to have a set of twins.....but there are MANY guys here making 400-500 RWHP with a good single......past 500 HP, you may want twins for the extra drivability......past 500 HP and the single is getting big. Yeah, your tiny HY will hold you back quickly, but there are many options out there for an upgraded single......Around here the B1 series of turbos are very popular and have proven to be a stout upgrade from the HX40. Check out High Tech Turbo these guys know there stuff and have helped many guys here get setup with some awesome single turbo CTD's!

 

I see no longevity issues up to say 450-500 HP....as long as you don't floor it everywhere. Our Cummins are so detuned by Dodge that the engine can handle some upgrades easily.

I have a B-1, and love it. But the Mfg is less than forthcoming with support or operational info. I believe HTT is now building a turbo as strong and as good as the B-1, with excellent customer support & service. That's where I would go if starting over again. Read their web site and, after deciding as best you can, where you think you want to end up (hp-wise) call Paul.

EGT's, with a single only become a problem at WOT...and than only over 400 HP, or if towing heavy. Not hard to live with...if you drive sensibly. At gross wt. I can turn my box down a little and drive anywhere in the country with no EGT concerns.

On your truck...a set of Mach 4's and a MAD ECM will get you 400 HP and never see 1200*...at sea level!

Your altitude may make it a little harder to handle temps but it's doable. How high up are you?

Well Denver, CO is a mile high above sea level. So I'm up there. I guess I could say I'm looking for around 400hp with a good single. Not sure what turbo would give me that. I have looked at the PDR HX-40, but have read about the weak shaft. So bomber wise what would be good? I can handle some lag, but not tons with a big turbo. And what would be good with my Comp? I will be sure to give the HTT guys ring. Thanks fellas

 

If your sure 400 hp will do it for you.. a piers Hybrid 35/40 would work. If it were me I'd get an HTB2 with a 12 cm housing. Good spool up and some extra air for hugher altitude. Think it would require a new HX-40 downpipe.

Listen to Rowland (rjohnson), he's a few steps ahead of me so I can follow his lead, learn from his attempts. I'm sure he's watching someone ahead of him, too!
If you have the option, get a wastegated exhaust housing, at 400hp you shouldn't need to go to external. Personally I like the Comp box (or any fuel box with in-cab on/off switch) because you can add or subtract 100hp at your whim.
Rowland, have you been at any elevation since the WG and injectors? Be interesting to see what the boost, EGT and smoke does up in thinner air...

 

Thanks for this great advice guys.

 

I'm in Denver too... a set of Mach4s and a B1-2... you'll like it You're tranny might not but you will lol.

 

I wanted the same from my truck...More power w/o sacrificing the reliability..165,000 miles and still going, no problems to speak of..I'm just under 500 HP, with the PDR 35 hybrid, which is very close to the dodgezilla turbo..I'm very happy with the result, tried several turbo/injector combos before settling on what I now run.

I wanted 0-60 fast...Not towing power, or pulling power. I wanted a truck that would accelerate quickly...Like you find on fwy onramps..I got just what I wanted..My 0-60 times are just a tick under 5 sec..Pretty impressive for a 7800 lb truck. No EGT problems, or other gremlins to speak of..It took alot of experimentation to get to this point..

Look at what the other guys are running... Learn from those of us who've been there, done that..You can pretty much pick from your choice of components to get the HP you want..If you want quick like mine, go with a moderate injector & smaller turbo..Want big? Go big..Injectors & turbo..A B-1 & a set of mach 3 or 4 edm's would make you smile too..And any of the boxes are good..Most here run a TST or Edge...both good..Just decide how much you want to spend, and choose accordingly...

 

Well anywhere from 400-500 hp with out EGT problems would be great. Plus the use of my Comp. And I have been reading the sigs when I notice guys runnin 1 big turbo. Just tryin to find the ideal turbo injector set up.

 

Well, the 1st thing you should do is get a trans... The stocker will not like any more power..You live in Colorado, take a look at ATS.. Its been a great trans so far, not so much as a slip out of it..But a DTT is really good too..Both about the same money..

Remember, the bigger the turbo, the longer you'll wait for it to spool.. But the more air it will flow once the revs catch up to it.. If you want spooling like your 9, then look at smaller turbos..like my 35 hybrid.. It spools every bit as fast as my 9 did, with enough air to cool what I'm running..Consider a "mad ecm" too..That will really wake up a sluggish truck.

 

I'm looking at DTT, I was talking to a BarryG here on DTR. And he recommended a shop that does DTT in Greeley, Performance Diesel Transmission. So I'm thinking I'm going that route. And I wouldn't mind some lag in a bigger turbo, just not tons. And what is an MAD ECM?

 

Its a reprogrammed ecm..Their are several vendors selling them here..Basically what it does is take the available fuel, and lets it hit at once..There is no gradual rate of fueling like the stock ecm..It makes for a very hard hitting acceleration right from the start. Its like a tst or edge box, without piercing the fuel wire..But when used in conjunction with a fuel box, it makes some serious power by eliminating that gradual fueling lag time..Its quite an improvment..Several people here are running them, me included..Ask Bob Wagner about them, he can explain it better than I can..

 

I'll check it out
