it should still give you an idea of what there is

Dropoff - I had put the turbo kit idea on the back burner because it looked like everyone was gonna wait until Speedtweaks had their kit out before buying anything. I'll see what I can come up with.

BD R/T - It's got some work done to the heads, headers, ignition, slicks, 1" lowering blocks in the rear and it's a RC. It's gone as fast as 12.20s in cool weather.

i know there's me and there was another dude at one time that "seemed" like he was ready to buy. the price of everything with the intercooler is the determining factor. i just may look around cali for shops and ask you for alot of help in building my own if noone else wants to haul @$$.

what all do you have done to your engine? ie, head work? HO cams? i know u have the F&B 72mm.. what exhaust setup you running?

what have you broken? at what psi? doing what?

Duner,

I've got a ton more questions for you in addition to Sgt G's ...

where you located?
how much boost are you running?
how do you avoid running lean? are the factory injectors enough?
have you dyno'd it?
any other mods other than those listed one your website (i.e. cams, heads, etc.)?
did you reprogram your PCM (if so, who did it)?
how do you handle fuel delivery?
ever thought about intercooling?
best ET?

Sorry if you've answered some of these questions a million other times but I hadn't really payed attention to your truck (though I'd heard about it) until I noticed your timeslips :)
that, and my buddy turned me onto turbos with his WRX (I was a S/C guy before, and still may be)

I'd be very interested in a turbo kit, but not until at least next year. Still getting on my feet here after finishing school.

thx!

As far as the engine... the only engine mod for the 12.76 run was a ported 68mm TB and narrowing the gap on the spark plugs to .035" instead of .040". Since then I've ported the heads added the 72mm TB, larger injectors and the Intercooler system. I plan on adding the HO cams before the Truckin' Nationals in October.

As far as exhaust... I built a new exhaust manifold for the passenger side to incorporate exhaust flow from both sides and also mount the turbo and wastegate. From the turbo it goes to a 3" downpipe, thru a 3" MorFlow catalytic convertor and out thru a full 3" Mopar cat-back system with a 70 series flowmaster. With the turbo it's virtually silent.

I was originally running the stock 19# Siemens injectors but they failed repetedly under the increased (insane) fuel pressures needed to keep up with the boost. These failures were painful but just part of a normal R&D effort. I knew there would be "issues" when I started the process, so it was just part of my "learning curve". The addition of larger Bosch injectors allowed me to run less fuel pressure and there have been no further problems with injectors.

I'm located in the Phoenix, AZ area.

I use a Vortech FMU to handle the fuel control when in boost. With the addition of a high pressure/volume fuel pump inline - it raises fuel pressure to compensate for increased fuel needs as boost rises. I was originally able to make the stock injectors keep up.... but it destroyed them. (And of course they managed to break at the most inopportune time)hehehe The new Bosch injectors are much better.

I am still negotiating with potential suppliers... but the initial startup costs are very prohibitive. I'll definately let everyone know if and when I iron anything out.

I'm running the new "oval" style 24# Cobra injectors. The PCM manages to trim the fuel just fine when in closed loop and they are just what the doctor ordered when in open loop.

IF I am the quickest(for right now).... it will be VERY short lived. I haven't done anything different than has been done thousands of times before.... I just did it to the 4.7.

I've heard reports of a NA 4.7 in Michigan that's running mid 13's already. There's probably 10 guys getting their 4.7s going right now that will probably blow the doors off mine! That's the nature of hot-rodding and racing in general. Somebody else is ALWAYS faster.

As far as the quickest thing goes.... I'm just a shadetree mechanic that decided to tinker with it a little. Just wait until some high-tech race outfit does something with this engine! Then you'll see some horsepower!

The rpm the turbo builds full boost at - is all dependent on how much load the engine is under and throttle position. It will make a full 12psi of boost as low as 2000 rpms, but that's mainly because the cfm requirement of the engine is lower at low rpms. As the engine rpms increase, the turbo rpms increase, the engine will use more airflow and the turbo will always stay ahead of the engine's appetite.

As far as immediate response - anything after 2600-2800 is neck snapping zero response time boost!

Say, did you know that Speedtweaks is talking about making a turbo kit for the 4.7L now? I know they just finished the twins on the R/T, but I asked Tom yesterday and he said they were planning on doing one up for the 4.7L.

Yeah, we found that out back in March when Speedtweaks announced that they would be building a turbo kit for all the Dodge truck motors. I'm not sure I can hold my breath for another 4 months, but we'll see how I do. Somehow, I bet the V-6 kit gets done first since Bernd's personal truck is a V-6.

SpeedTweaks has had plans for their 4.7 turbo kit "in the works" for quite some time. That is one of the biggest reasons why I didn't put a kit on the market. Very few people were willing to put any money down on a kit until they could compare the two kits and prices together. Since that could take some time..... I just put the idea aside and went onto other things.

well I guess I'm 'fortunate' enough to be poor right now and couldn't afford the kit either way, so I'm better off waiting to see what next year brings anyways.

Have you ever considered just selling the system that's on your truck Duner, and making another one? I guess that system probably cost you more that $4000 to complete though in the end.

and alex, I agree with you that the V6 will get done first, but I bet it will use 99% the same components as the 4.7L will. (I personally think the V6 is a waste of time to sink that much money into ... but thats just me, and I bet there's a lot of 5.9ers that would say the same thing about the 4.7L)

Actually I bet you'll see a lot of the 5.9 kit appear on the V-6 since they are they same base motor (the V-6 is missing 2 cylinders, but other than that, it's the same block).

And the reason you waste time on turbo'ing the V-6 is that it will allow the brave V-6 owner to run 13's and even 12's in the 1/4 mile in a truck that's nearly silent and weighs a lot less than the V-8's. As in: not just kick ass drag racing/sleeper potential, but it could be made to handle really well, too.
