Glad to hear it! I understand why you wanted a new turbo but what made you pick the GDS ball-buster?
Availabilty, price, and a ton of research.

Well, it may not be for everyone. If all I did was drive this truck as my daily commuter in traffic, maybe I'd feel a bit differently. If my max speed was 55 MPH, I'd really be disappointed!! However, I have open interstate to drive on every day with no traffic and lots of "leg room".

I'm not doing an article. If you scroll up a few posts, you'll see where Kris (strokin' it) has linked to a much better writeup than I could have done. Start to finish, about 1 hour 15 minutes. It helps that I have done quite a few turbo 'remove and replace' or 'remove and reinstall with tight exhaust housing bolts' on these powerstrokes.

That would be the ticket there....but at what cost? I kind of enjoyed paying less than $1400 for the turbo, the outlet, and the shipping......
I forgot to mention the mileage difference. Keep in mind that I HAVE NOT yet done an actual longhand mileage calculation, but the lie-o-meter gives me another 1-2 MPG more than before the changeover.....likely due to the lower MAP readings (3-4 PSI vs. 5-7 PSI continuous).
Thanks, It is sounding more and more like this might be for me too. I pull 15k - 20k two or three times aweek. Not always on interstate but very much city mileage. Here in SW Missouri we have lots of hills and curves so I'm always have to pull hard up grades and currently my egt's get a to close for comfort. That is why I'm thinking of upgrading the turbo. I have already done the guages, chip, tymar intake, 4in exhuast, 19.5 load range G tires (my truck is a swa) trans lock (on old trans that puked on tuesday) and an exhuast brake, new BTS being installed as I write. So, I'm thinking a turbo upgrade is the next needed mod.

What is your rear axle ratio? That will make the biggest difference.
If you tow a lot of weight short distances then you will be happiest with a very low geared axle. It will remove all the effort required to get the trailer going.
Not that the turbo wouldn't help, but if you have the 3.73 axle then it's not the best bang for the buck, IMO.
Cleatus, to put it simply, boost is a measurement of restriction. You are now flowing more CFM of air, however at a lower pressure. Which is always easier on everything. I can max out at 30-31psi however on my 80hp program, and a shift flare to 32psi. My 120 and 140 programs make no more than 27-28psi of boost, i loose snuff on the top end with those from oil pressure problems.
Yeah Kris, I understand boost being the measurement of restriction. That's why I'm happy with the way the truck runs even though I'm only capable of 25 PSI. However, it doesn't make sense to me why I still POUR out the black smoke even at 3000+ RPM. The gauge needle instantly hits 25 PSI and stops dead in its' tracks...from 2300 RPM all the way to redline in EVERY program from 60 HP on up to 120.
[QUOTEMaybe I'm a little disappointed in my lack of peak boost. I've said it before, but there's absolutely more power there than with the stocker....just not as much boost. More air in and out I suppose. I guess it's better to run a max of 25 PSI and make more power than running 30+ constantly. Sure wish I knew what was going on there, though.
[/QUOTE]
its not really a restriction if talking on the intake side. you are still moving the same volume of air at 25 PSI as your other turbo did. The size of the intake Chamber didn't change. However when you put the 1.0 housing on. . . it made it more efficient by lowering backpressure. So you are actually cramming a little bit less air in there then before. . . but you feel more power because less of that air is being used to drive the turbo. There is less restriction on the exhaust side. that might be why you still have a little smoke when all turboed up. Although I would think the smoke would clear up pretty nice. How much smoke are we talking about?

Tim, if I took a video of how much black smoke still comes out of this thing, you'd cry. I'm smoking as much at 3000 RPM in 80 and 120 as 60 does from a standing start. I mean, I LOVE this turbo and how the truck now THROWS you into the seatback vs. giving you a pretty good shove like before. Not only that, but towing (which is the main reason for purchase) is like nothing before...I wouldn't trade this thing for the world when it comes to towing 15K+.
cleatus- i have a ball buster also, i know what u mean about about the only geting 25 psi of boost, on matter what you do it just says right there. i changed out the stock boots, i cant remember the brand that i bought, but the new boots gave me about 3 more psi.. might be worth a try, i want to install a 6.0 I/C to help get the EGTs down..
if you really want more boost try a little shot of propane, i run about a 25hp shot and if im not careful 35psi is very easy to get to... even with propane and 60tow i have yet to get over 1150* but i have yet to tow in weather over 90* ,this summer will be a good test.
Kiwk,
I have the 3.73 gears so are you saying I should change to 4.10s? Since my truck is a 4x4 the gear change would be about the same as a turbo I would think. However, I did upgrade my stock tires and rims to the commercial 19.5 tire size so this has change my gear ratio some what but I didn't notice much (if any difference) when they where first installed.
I think it will depend a lot on the type of driving you do. I have 3.73's in my truck and feel that it's about perfect on the highway, even while towing. It's a little laggy around town with my van turbo, but out on the highway it's about perfect, and most of my truck's driving is done on the highway. For me, 4.10's would be too tall I think.
Most of my driving is pulling 20k+, 50+miles each way 2 to 3 times a week. The roads are mostly 2 lane hilling and curvy (ozark mountians). The loads I'm carrying are my heavy equipment so one day I might take out my trailer and loader then that evening and the next day I might just dead head back and forth to the job. When done with that job I hook up my trailer and loader again and go to the next job. My average speed with the trailer and equipment is 50-60 mph, without the load 65-70.
I would venture to say that the 4.10 gear change would be good for you then, especially while towing that heavy of a load at lower speeds. Most of the time I'm on open interstates where I can cruise at 70-75.
I agree with JT. If I were to tow at speeds of 55-60 all the time, my 3.73 ratio would suck....especially with a bigger turbo. The tranny would be happier in third gear all the time though.....
I would venture to say that a smaller exhaust housing (the .84 A/R) would be a LOT better if you were always towing at less than 70 MPH. I would consider a regear to AT LEAST 4.10s if towing that slow with a 1.0 A/R or larger housing.

Not with PMRs I won't run propane. It's not really that big of an issue for me to ONLY make 25 PSI of boost, it's actually probably better for the engine anyways.....it just boggles my mind why there's actually still fuel left to burn and it's not being utilized. I think that Hiflyer746 is about on the right track....just something I have to live with. It is kind of fun burning up a hill or passing someone and pouring the coals....and still keeping the EGTs at a safe level. Couldn't do that before. 1200 degrees in just a few seconds is NO FUN!!!
