Deciding on Compounds
 
Hey fellas. Well I'm making the plunge when I get back from Afghanistan to bolt on compounds. The only thing I am planning to do at the time I do the compounds is head studs. Not looking at doing injectors or a cp3 upgrade quite yet. The kit that I'm looking at right now is the Diesel Power Source D-Tech 62 over an S475. Is anyone running this kit, if so what information can you share. Still working on a semi limited budget, so that will play a factor. Mainly looking for a good all around rig, but right now at 3/4 WOT im pegging out my 1600 pyro gauge and i need to get my EGTS in check. I still have some time here in Afghanistan just doing some research and seeing what the best suited is going to be. Thanks in advance for any advice. :c:

I just installed that kit on my truck last saturday. Just workin all of the bugs out of it now. It does as they say and I have yet to see the EGT's get over 1100. Good kit for the money. Plan on a full day for install. Mine didn't fit for sh!t.

just beware of the d tech turbo its a china turbo, not saying its junk just becareful, II and wicked diesel, and many others have good kits out there remember you get what you pay for

I agree. you have to know about what your gonna spend $$ for. But on the otherhand I've heard good reviews on these kits and its doin everything that I'm askin it to do so far. OP, If you don't already it would be a good idea to invest in headstuds at least. This kit is gated at 55, and mine gets there. :c:

IrishMan85 08-01-2011 07:17 AM

hey thanks for the advice so far fellas. Redsled what do you know about the D-Tech turbos that I should be aware of? KXTRAP Yes I am deffinetly planning on putting head studs when I do the install. Do you know have any complaints about the setup, or would have liked to have gone with a different kit (within your budget of course). Right now the DPS kit is the most complete kit that I have found for the money.

I would only do that kit if you plan on doing at least bigger nozzles in the near future. I have this kit on my 01, makes 60 psi with my fueling but still hits 1450 degrees. Really not too too bad, but something to think about. It seems like the commonrails are running better on the dps compounds than the 2nd gens. Starting to see a trend. As far as the d techs go, if you're not planning on extreme competition they seem to be holding up for everyone. There's a few guys on here that have some high miles on the d techs without problems, but I hear from some of the competition guys that they burn up easy once you really get them pushing some boost. That setup might be a little laggy without at least a bigger set of nozzles. Good luck bud

Mine seems to be ok with my 90's. But I also put the stg III CP3 on the day before the turbos. The bracket that hooks the 475 to that back 2 top manifold bolts didn't fit for crap on mine. I ended up cutting the bracket in half, mocking everything up, tacking the bracket, and then finish welding it. Maybe others had better luck but mine was about 1/2" too far front and out of range in the slotted holes.

IrishMan85 08-01-2011 03:41 PM

kingbrad well I dont really plan on sled pulling drag racing or really beating on the truck too bad so sounds like the d tech will hold up for my build. Thanks for the heads up though if I ever do venture down that road
KXTRAP43 I am planning on putting on 110hp sticks and an upgraded cp3 but I wouldnt so call it happening in the near future. I can deal with the truck being a little laggy but do you think that it will too laggy? Also that sounds like a PITA with the upper manifold. Was it a difficult part to manfacture or just a PITA Thanks for all the help so far fellas.

07redsled 08-01-2011 08:11 PM

as far as the d techs go its all in the fact that they are china turbos with not as good parts and labor, turbos need to be good or they will cost a engine which anit cheap believe me ive been there

It shouldn't be unbearably laggy. Im on my phone so I can't see your signature to see if your truck is auto or manual. But if it's a manual, the lag won't bother you too much just for the fact that you can give it some throttle before you start moving. The autos like mine just take a sec to light the turbos, you might get a little smoky while underspooled but you'll be fine until you get your fueling. I like to see that you're adding air first rather than fuel. That's a rarity, go you!

IrishMan85 08-02-2011 04:48 AM

kingbrad yes truck is an automatic with a Suncoast triple disk TC with a 1400 RPM stall. and it already smokes like a locomotive when i take off from a stop so like you said i should be alright with spool up. and yeah my egts are threw the roof right now so i kinda had to start pushin more air and what better way than with compounds!

K80 08-02-2011 06:18 AM

Well your automatic may be different but mine is more responsive now. And it was kinda a PITA for the bracket deal. Also if your planning on running drive pressure, take that into effect when assembling these things. I'm in that boat as an afterthought now :argh:. Both of the bottom plugs in the manifold are more or less hidden by the 475 and I really don't feel like disassembling it or drilling a manifold that already has 3 ports!!

Yeah when I did my compounds I flipped my manifold that was egt tapped on the top side. Didn't want to drill another hole so my egt probe is on the underside of the manifold. I couldn't get to it if I wanted to!

I hear ya. There is no way in hell anything is going in the 1/16 NPT hole. I can see the 1/8" NPT one but it is about 3/8" away from the 475 housing and just in front of it. I was debating making my own adapter but IDK yet.

Sounds like Swiss cheese lol

K80 08-02-2011 02:28 PM

Pretty close to it. Lol

IrishMan85 08-02-2011 08:15 PM

KXTRAP now when you say running drive pressure exactly what are you reffering too. Cause I have a boost gauge and im getting my boost reading from a tap in my intake manifold. Also the pyrometer is their a place to install thats easily accessible or is it more like a renco oven where you set it and forget it cause you'll never see it again. Also I have a bladerunner afe manifold could I use this manifold or be better off to use to one supplied with the kit

K80 08-03-2011 06:58 AM

Drive pressure is what is driving the turbo(s). It's measured in psi at the exhaust manifold. The ideal drive pressure to boost ratio is 1:1. I was told when running compounds that having a DP gauge is a good idea. Your talin a bladerunner exhaust manifold right? (just to make sure, they have the same name for their intake) It doesn't matter. DPS seems to be more on the economy side. Your AFE probably will work just flip it.

Yeah it's basically running a boost gauge off of your exhaust manifold. It should read very close to your boost pressure. There are theories that when drive pressure is higher than the boost, that blown head gaskets result. If you do a drive pressure gauge make sure you use a few feet of metal line coiled up before the nylon line, just so the nylon line doesn't melt from the exhaust and manifold heat. You can buy drive pressure gauge kits that come with everything you need

Autometer sells a copper coil kit for this. I got mine from Aligator, i believe it was something like $16 or something like that.

IrishMan85 08-04-2011 12:14 AM

wow thanks for all the great information fellas. now does anyone have any contact info for the folks at DPS as in who would be the right person to talk to about if my AFE exhaust manifold will work with the twins setup or not and also about pricing. I say pricing... won't be buyin nothin if Uncle Sam takes half my paycheck away, and how you gonna take a mans paycheck thats deployed, isn't bein away from family and gettin shot at payment enough? Thanks again for all the info fellas sure has been helpful!!:c:

Send an email to "sales@dieselpowersource.com" with your questions. Theyre usually very good about getting back to you quickly.

Diesel Power Source

I called them with a question about the 475 using one of the numbers on their home page. The guy I talked to was very helpfull and actually spoke understandable english!

BoldCummins 08-05-2011 04:03 PM

I too have called diesel power source a few times and found them to be very helpful and straight forward. I love my diesel power source compounds, they have kept my temps down and spool really well. My brother-in-law went with a different company and is not seeing such good results (which I tend to think is funny). I had the same feelings as you are having before I took the plunge and finally got twins. But now I am very glad I did it. I am on the verge of buying a new truck within the next few months and I plan on going with the Diesel Power Source twins again. Good Luck.
