DakGuy, your setup sounds identical to mine. I haven't ever taken my truck to the track. Did you do any mods before attaining that 14.9 second 1/4 mile? Was it on stock sized tires? Just curious... no one ever tests the setup I want them to in magazines.

Conekiller I have made one mod to the truck and that is the homemade intake. However I haven't made a pass with it on yet. That time was with everything completely STOCK. I didn't even lower the air pressure in the rear tires. I probably could have done better but the truck was a week old and that was only the 3rd run.

Well Duner my old car could handle out 17lbs of boost on reg 93 pump gas and never had any knock and was mostly all stock and to top it off it was only a 6.

I was wondering about the exhaust manifolds.
Are they one-offs? I have been considering buying a new 4.7 or r/t (my 4.7 was totalled). are u running single or twin turbo? I can get all the neccesary turbo parts except for the manifolds and would like to build a turbo 4.7. I am jst curious about your setup.

Wiley - The set-up is almost a clone of a Buick Grand National. It's a single turbo which is mounted on the passenger side. I use the stock exhaust manifold from the driver's side and route the crossover pipe to the other manifold. I have fabricated a manifold for the passenger side. This manifold brings exhaust in from the driver's side and mixes it with the exhaust from the passenger side (similar to how the Buick does it). The turbo and adjustable wastegate both mount to this manifold. I'm using a Garrett T4 turbo. The turbo outlet goes right in front of the AC lines on the compressor. I fabricated a spacer for the oil fill stand pipe, which will act as an oil return from the turbo also. The spacer allows the intake pipe to pass behind the oil fill tube. The fabrication of the exhaust system was fairly difficult. It's pretty tough to snake a full 3" tube out of the turbo, under the AC dryer and then down to meet the rest of the exhaust system. I am running a fuel pump for a super-60, 2.2L turbo car. It makes 120 psi. I'm running a Vortech fmu , which will allow more fuel pressure as boost pressure rises. Right now there isn't any boost timing retard system available, so I'm going to limit it to 7 lbs of boost for now. The new ignition will be available at the end of the year I'm told by MSD. I have a spearco water injection unit coming (it should be here tomorrow). Depending upon how well the initial 7 lbs works, I can always turn it up the boost. I also have an intercooler in mind - but that will require more fabrication...and time.
Toast - I love those GNs! A buddy of mine took his out to the track last friday night. He felt roudy so he turned up the boost a little bit - 22 lbs and it went 12.36! hahaha
Since most of the fabrication of these parts has been cnc'd, I might consider putting out some of the parts in a kit form if there is much interest....

Thank You!!! Your setup description is very informative. Sounds like it should work pretty good. I am Greatly interested in the possible kit. I don't remember off hand the price for a water injection kit, but for the same cash (+ a little more) couldn't you go with DFI to get the boost timing retard? I know the W.I.K's help with the possible detonation, but DFI seems like a simpler answer. just a lot of test and tune but in the long run, better.

Unfortunately, there is no ignition system currently available for an 8-channel digital coil on plug system. Everything is either for older stuff like the 5.9s with their distributor type ignition or for the GM & Fords which are 4 channel digital. In order to make those work you have to buy about $1600.00 worth of stuff! But if I wait until the first of the year, I can have a stand alone MSD system for about $400.00. I think it's worth less boost for a couple of months. The Spearco water injection kit probably isn't the best on the market, but for $200.00 it should get me by.
I'll keep everybody posted about how well the system works. If it does, I will probably produce some kits or at least the parts that make it work.

I just finished my turbo install. Well sort of. I finished about 3 hours ago and have been driving it and dialing it in since then. I am completely satisfied with the outcum. This thing has perfect drivability and hauls major butt! It still need some fine tuning, but for the most part it's finished. It's been raining outside so I didn't have a chance to Gtech it yet. I can tell you this...... If you lean into the throttle and you are doing less than 75-80, you better be ready to get out of the throttle. In the rain the wheelspin is pretty uncontrollable when the boost hits.
Another issue with the truck now is noise.... or the total lack of it. There is no turbo whine. There is barely any audible exhaust sound! This thing is way quieter than it was bone stock. Wow - talk about a sleeper!

Well Congrats Dunner! It sounds like all that hard work paid off! Would it be safe to say your the first to Turbo charge a 4.7? How about some picks of the setup :) And some 1/4 numbers when you get the chance.

Oh you can count on me taking some pics. I will also get some dyno numbers on it too. As far as 1/4 numbers.... next weekend is the Truckin' Nationals. I'll have 2 days to get some good timeslips done.
As far as I know.... I'm the first to turbocharge a 4.7. I had to make everything pretty much from scratch - but it was very much well worth it!

Isn't the 4.7 built by Mercedes anyway? I don't consider it a true "Mopar" engine.
As far as Mopar V8's go, I have dis assembled 318's that had over 200k miles on them and could STILL see the "cross hatch" distinctively in the cylinder walls!
Myself and my family have had 318's, 360's, 400's, and even a 413I (in a motorhome) and you have to drive them close to 300k miles to get them to smoke. And then, none of them I can remember EVER got a rod knock or lost any noticable oil pressure.
Some FORD's may come close to that (351W / 302W), but FORGET it with the Chevy 350 or especially the doggy Chevy 454 (noisy P.O.S.)!!!
I hope they keep the 5.9 available in the Dakota for a long time to come or it will be a sad mistake! If they discontinued the 5.9, I'd by a USED truck with a 5.9 before buying a new 4.7!
