So it has been a while since I have posted but I have been busy putting new mods on the truck):h and driving as much as possible to test them each before I added another. Over the last 2 months I lifted my truck(2 inches), installed firestone overload airbags, new HO injectors, new glow plugs, ATT turbo, and last but not least Devils Own WMI. Well I just recently got done with them all and all I can say is this is not even the same truck I started with!!!!!(this is a good thing:D) I figured I would post this all together and break down each item as I added it. I have some pics also that I will try to get loaded up tomorrow. The first to go on was the lift which I did to get a little more clearance for the 33's that I am running. I researched a lot of options and with only needing about 2 inches of lift I cranked up the torsion bars and added rear lift blocks. The ride is a little stiffer but not that bad and now the 33's clear very nicely; they only used to rub on sharp turns. Also the lift gave the truck a more aggressive stance. Adding the bloack and cranking the torsion bars only took about 2 hours total to do and was about 75 dollars to do:thumbsup:. After I did the lift I added the firestone air bags. The reason I did this I because when I pull my car hauler with the Jeep on it or the big sled trailer the back end sags a couple of inches with the trailers attached to it. The bags were fairly easy to install(use a cobalt drill bit for the frame) and the kit was complete with everything you would need. I also installed a gauge and compressor so that I could fill and deflate the bags to the pressure I need from the cab. Now with the truck hooked to either trailer it sits nice and level, and you can adjust the air pressure as you drive depending on how heavy the load is, how rough the road is, and how smooth you want it to ride.
 
The next thing I installed was new glow plugs and HO injectors. I have known since I bought the truck that it needed injectors I have just been putting it off, till now. The install was not as hard as I thought it was going to be, but don't get me wrong it was by no means a piece of cake:eek: I did the drivers side first and did one injector and glow plug at a time. The injectors were OEM and with 187,000 miles on the truck they were way past due of being replaced. The glow plugs that were in the truck had been installed in the last couple years I am guessing and were the 60G's and seemed to be in good shape but I decided to replace them anyways while I was there. The drivers side was done in less than and hour and then I moved on to the passenger side:nonod:. I was going to do this side without removing the turbo but after fighting it for a while I decided to remove the turbo anyways. It only took about twenty minutes to remove the turbo, I was lucky and none of the bolts were seized up. After removing the turbo it was much easier to do the middle two injectors and glow plugs, but the last injector, which is almost against the harness running along the firewall, was a nightmare:mad2:. It took me as long to do that injector as it did to do all of the other ones:rolleyes5:. Anyway total I was about four hours into doing the swap, not a pro by any means!! LOL I reinstalled the turbo full knowing that in a couple of weeks I would have my ATT but I wanted to be able to see the difference the injectors made and then see what just the turbo did. The first thing I noticed with the new injectors is the truck starts much, much easier and it idles a lot smoother. Some of the other things I noticed is when I stomped on it it blew some black smoke and held you back in the seat a little bit, so it defiantly felt like it had some more power; but also remember my old injectors had 187,000 miles on them:rolleyes5:. The other thing I noticed is that at night when I am sitting at the gas station the haze that used to come out of the exhaust that you could see in the lights was gone. I never really noticed a fuel mileage increase, but it was probably because I was in the pedal more enjoying the new found power; but on a good note I did not see a decrease in mileage either:D. All I can say is it was money very well spent, I wish I would have done it when I first got the truck.
 
Next I installed the ATT!! First I have to say Dennis is a stand up guy with a great product, any questions I had he was right there to answer them, even when it was late when I was installing the turbo.:yawn:. The turbo set up was really nice and it came with everything short of some hose clamps, simple enough!! I pulled the old turbo off, getting good at that now:D, and installed the new turbo which thanks to Dennis went real smooth due to the fab work and detailed instructions. The reason I went with the ATT turbo in the first place is my truck did not seem to have the power it needed when I was towing up big hills. Previous to the ATT I had done almost all of the upgrades short of injectors and figuring out something different with the intake, but the truck just didn't have the power it needed to pull the hills, the engine would stay cool but the EGT's would shoot up to 1200 degrees in no time so I would have to back out of the throttle some and there for lose speed up the hill to the tune of 40mph:( So after getting the new turbo on the next morning I took the truck for a spin to "season" the turbo. My first impressions were(I will expand on each): louder exhaust, engine used less boost, little bit slower spool, quieter turbo whine. First the louder exhaust, the truck doesn't seem way louder it just has a different tone to it, which is nice, a good rumble. Second as I drove through town the turbo hardly made the boost gauge even move and I was driving in the same areas of town where I would normally take off and use 3-4 pounds of boost, this I immediately thought was a very good thing. Third the slower spool, the turbo seemed to lag just a bit off the line but I have got to say now after six weeks of having the turbo on the lag is all but gone, hardly even noticeable now. The last thing I noticed on my initial drive was the turbo was quieter, which I was also excited about cause I get tired of hearing the old turbo whistle on the long pulls up hills when it is working hard, sometimes it was loud enough that I had to turn the music up a bit to tone it out a little:eek:.
 
Sorry this is getting lengthy. After a day or two of regular driving I wanted to go out and see what the turbo could do, so I hooked the truck to my car hauler and loaded my Jeep on board. The total combined weight is probably somewhere in the 7500 range. I pulled out on the highway to head to a hill I was familiar with towing on so that I could get a good comparison of what the turbo was doing for me, as soon as I got on the highway I put my foot into it so I could see what this turbo was all about. With my old turbo I would get on it and the boost would jump up and the truck would progressively gain speed as I went, not fast but fairly steady but it would hit 1200 degrees real quick and I would have to back out of it a little.(this was just on level highway but loaded) So I stepped on it with the ATT on board and we started rolling and the gauge was showing an increase of boost....3.....4.....5..... well when I got to 8 the truck started pulling real hard, real hard, I was shocked:yikes: I could not believe it we were gaining speed quite rapidly. I watched the EGT's closely and they were climbing also and I figured pretty soon I would have to back out, but to my surprise again when I got to about twelve pounds of boost on the gauge the EGT's leveled off and stopped climbing!!!!!:D:D:D:D If this was all the turbo did I would be happier than a pig in:shiiiiiite: but it has done so much more for the truck. When I got to the hill I was able to maintain 60 miles an hour(48 without ATT) and the EGT's were around 1050(1200 without ATT) and I had quite a bit of pedal left to go. I was so impressed I could not believe it the truck was a whole new beast!! I have been driving it now for over six weeks and it is hands down one of, if not the best thing I have ever done on this truck. If anyone wants anymore info or details I would be happy to help out. I just recently got done with an 800 mile trip pulling a car hauler loaded with a 72 chevy, and could not be happier with the ATT, it does everything promised and more. Props to Dennis for such a great product and for all the time he spent making sure it worked right.
 
Great write up. I'm sure you had fun doing all the mods and now your ecstatic driving w/ them installed.

Thanks for the write up. The A-Team Turbo was designed to be an easy install. I hated complicated modifications as a mechanic and especially hated BS mods that didn't have what was needed.

I do as an owner, love my truck with an A-Team Turbo. I have been happy with it and would never go back to having a GM- turbo. The project as you know was a collaborated effort by more people than just me. Hank1948 did the original machine work and Turbine Doc has been the Ginny Pig on a lot (most) of the testing. I know turbine Doc has more miles on his turbo than I do. I have 13,000 miles on mine and I know he has much more than that.

A lot of testing went in before we even tried to sell a Turbo. The DTR family is first and foremost for ATT. We want the purchaser to be happy and satisfied with their purchase. Customer service in my book is getting what you paid for at a reasonable price and having a no BS true to life expectation of what you can expect from our product. ALSO you should be able to SPEAK with someone in person not leave a message and wait for a call. If your calling me, you want to speak to someone now; not in a few hours or days. I hope to keep it that way):h.
 
Thanks for the write up, I remember all your inquiries to increase power before. Im waiting to see and hear about the WMI and what difference it made.

Im hoping to get an ATT soon. I was waiting for that to take the intake off and work on the WMI too, but I could see if WMI gets me IATs under 200*F with the GM4 at 100MPH :)
 
Okay so for the last part of this....WMI!! So I bought my kit a couple months ago and the plan was to install in and hopefully keep my EGT's down while towing. I bought the Devils Own EGT kit which you can set the temp the spray starts at and it progressively increases to a full spray at the high temp which you set also. After I got the kit sometime in January I made the decision to wait to install it and get new injectors and also in the mean time I decided that I NEEDED and ATT!:D So I installed everything else first then the WMI. Needless to say the truck was running great with the ATT and the new injectors but now I had more power that I was hoping to use climbing hills while towing and keep the EGT's down; the EGT's were much better with the ATT but I wanted to be able to push the pedal harder(more power) and keep the EGT's lower even still. The install on the WMI was fairly easy including the controller. I installed one single 10gph nozzle, it has been recommended to me to use a 1gph nozzle in front of the turbo but I have yet to play with that at this point. On to the good stuff... after everything was installed I loaded the car hauler again and I headed to my familiar hill. The WMI can be mixed up to 50/50 but I wanted it to cool more than i needed power so I mixed at 20/80. I took the truck up the hill with a starting speed of about 60mph and the ATT took me all the way to the top without losing speed, I only downshifted to 3rd, and the EGT's were around 1150. SO at this point that is WAY better than the truck could of ever done before, but I had about 1/3 of my pedal left and I wanted to use the power but I knew I would quickly build heat. I went back down the hill and I set my WMI to kick on at 680 degrees and full spray at 1100. So back up the hill I went but this time because of a slow truck my starting speed was only 50mph but I hit the start mark for the EGT temp pretty quick and the WMI kicked in, immediately the EGT's slowed there climb...SO I gave it more pedal!!:D The EGT's started increasing but so did my speed rather rapidly(considering the weight I was pulling up a hill). The hotter the EGTs got the more the WMI sprayed. When the truck hit 1100 degrees the WMI was spraying at full and the EGT's actually started to decline....and the truck was pulling like a locamotive!!!:eek::eek: By the top of the hill the WMI was still spraying full, I had the pedal most of the way to the floor, I was going 76 miles and hour, and the EGT's were at a nice 1120 Degrees...absolutely incredible.
 
Sorry my posts are so long but I want to get you guys all the info. Now that I have played with my WMI more I have changed a couple things and there are a few more things I am going to try. First I am wicked happy with the WMI and consider it and the ATT the two best things I have done to the truck. One of the things I changed is I put a switch of the WMI so I can turn it on and off when I want, other wise it comes on at what ever temps you have it set to. I really like the 20% mix it is a good blend of power and cooling, and despite what some people say you can feel it "seat of the pants" even with a 20% mix. Also another thing that has been kind of fun about the WMI is I have been using it as a passing gear so to speak. When I need to pass someone I kick the switch on and I have the temp set low so that it starts spraying right when I kick it on and the truck pulls strongly ahead without having to kick down a gear on the tranny. So a couple of the things I am going to try is a bigger nozzle like a 14gph instead of the 10, cause the engine doesn't bog at all so I want to see if I can get better results or if that is to much. I also am going to try a 1gph nozzle in front of the turbo and see what kind of results I get and I will for sure keep you all posted. Now for the pics.....
 
Sounds like you have a winning combination there, congratulations. I may have to look into WMI.

To answer the above question, half of the trip(400 miles) was with just the car hauler on(2400lbs) and the last half was made loaded with a truck(between 7-8000lbs). I have two tanks and never had to refill, sweet, and when I got back the truck to 58 gallons to get the diesel back to the top. I wish I would of checked mileage empty and loaded, but I figured for doing the speed limit(75) the whole trip just under 14 miles to the gallon was great, it would of probably been better if I drove slower; then again what fun is that:D

Not sure why someone would recommend water before the turbo, that is usually taboo.

Also the higher percentages of methanol can cause predetonation issues with the IDI, so youre better off keeping it at 20%. So if people making recommendations are direct injected power people, take a lot of it with a grain of salt.

10GPH is already big for our low power engines. What is the pressure of the pump with the kit? Having the progressive controller is nice, thats a great way to run that.

Glad it works really well, going to set a trend....
 
Well after a month or so of running it and getting a real good feel for it, I will try the bigger nozzle, I have a buddy with the same truck but stock turbo running the 14gph with no issues. As far as the mix goes I definitely have not experienced any pre-detonation. I think 20% is a real good ratio for my set up, good power, and really cools the EGT's. As far as the nozzle pre turbo I have been a little leary of trying that especially with my new turbo:nono: I have still been researching it trying to get all the info I can and so far it looks like the most common use for the pre turbo nozzle is that is helps you build boost quicker, which for my application, I don't really need. So unless I find out that it will help with efficiency or cooling I am going to stick with the after turbo nozzle.
 
ANy notice in increase in mpg's with the att??? I am VERY interested and am thinking about getting one
