Here's the Deal:

I love my truck and all of the performance upgrades that have been added. There is no doubt whatsoever that the truck's power is light years beyond what is was in stock form. However, I am having some issues that I wanted to get your advice on to see what, if anything, can be done about them.

(1) What exactly should I have the tech(s) look at as far as the rattling at idle with and without the clutch being pushed in. The Fluidampr has done absolutely nothing and I do not know if it is just not affective or if it needs to be adjusted or something else.

(2) All of a sudden, my truck is starting to idle very rough and cause a lot of shudder and vibration upon start up and white smoke is pouring out of the exhaust. This goes away after warmup (the white smoke), but the shudder does not always.

(3) The FASS pump is louder than hell and I wanted to know if the GDP 392 would be an upgrade or downgrade. Also, it fluctuates in sound (louder then softer, louder then softer) when it idles. Is this normal? Lastly, is it possible to mount the FASS system so that it takes fuel all the way from the bottom of the tank like the OEM one does or do I need the Transfer Flow tank replace,ent in order to mount the FASS to it? I only ask because now I am running out of fuel between 40-50 Miles on the "DIstance to Empty" readout.

(4) The SBC 3850 clutch CANNOT be started smoothly if you are not in "L". Is there anything that can be done? If I engage in 2nd, whether I use high RPMs or low, or just ease out the clutch, it starts smoothly but then gets VERY jerky just before full engagement. I am confused as to why this is the case. I wouldn't mind starting out in "L" all the time, except for the fact that you only get to about 5 before you have to shift!!!!!!

(5) The drone and "deep rattle" that occurs when you have 4th or 5th in low RPM situations is insane! I do not know if it is the exhaust vibrating or what but it sets of speed sensors and the parkbrake sensor every time. Anything that can be done about this?

(6) Basically what I am trying to accomplish with my setup is maximizing the CR engine to get every ounce of RELIABLE power I can, but, at the same time, I want to give it as much a STOCK feel and DRIVABILITY as is possible.

(7) Are there any upgrades that I should or need to add or change given my setup?

(8) Lastly, what do I need to have checked now that I have 800 miles on the truck with the upgrades before I go about "turning the wick up" on everything ? How do I turn up the boost on my twins all the way?

I LOVE my setup, but there are just some things that I am trying to fix because I use this truck all of the time and on longer drives, or even driving around town it can be annoying. I wnat the truck to sound like a deep rumbling monster, not some rattling loud junker, you know what I mean???


I appreciate any and all help on this matter!

Oh wiggs you kill me man that rattle is prob your DD clutch rattilin together and they don't shift smooth I wonder if you got the dump truck clutch? Fass pumps are loud that is why mine is mounted way in the back. When your driving try to avoid 1800 rpm range this is when it drowns the most try havin stacks! either keep it in a lower gear and keep the rpm's up or drop in a really high gear when cruising at lets say 35 mph. You will no longer feel stock buddy you built the beast and now you have to listen to the bark. Also you need to let that thing warm up in the morning and also plug it in this will probably solve the white smoke and rough idle hopefully.

Most of these questions I can't answer, but one thing that popped in my mind is you're supplying all this fuel to your rig via the larger injectors while driving the truck very conservatively. Could it be that your injectors are starting to carbon up, causing the rougher than normal idle and such? If you go out and flog it for a spell does it clear up at all? If you haven't got her good and hot in a while (keep your minds out of the gutter ) maybe its time to do so.

1. Its called a dual disk clutch. They rattle and make noise like they are crushing corn.

3. I would call Richard at GDP and have him hook you up with whatever you need to convert over to his system.

8. I would retorque the studs if you havent already and start turning it up a little.

If you want a nice DEEP sound go with 6 inch stacks. I have a really deep tone. With a nice muffler I think it would be the ultimate sound.

COUNTRYBOY

Glacier Diesel is the way to go, but make sure you get the performance set up... Like Luken said, 6 inch stacks are the way to go....

For me, the drone occurs at the 1500RPM range and is almost gone by 1800. I always let it warm up. I can't wait till the pin and ECU grounding or whatever the hell it is is done so that my high-idle will work becaus eI hate having to use my foot!!

I definitely do not drive the truck conservatively, I just have the settings on conservatively. I have floored and run it through the gears several times, especially getting on and off the Parkway in Pittsburgh where they still have STOP signs at all of the on ramps!!!! I have also made two 3 hours trip back and forth to Columbus so the engine has gotten some good use lately.

According to the TST, I have hit 1380 on the EGTs as my high with the setting on 4/4. Once the RPMs pass 2000, that started coming down. My Pyro (pre-turbo) has never even shown 1000. What do you think those EGTs would be with 6" stacks WITH a muffler ?

The white smoke is gone once the engine is heated up.

Lastly, is there a reason why when I turn the MP-8 **** all the way to the left (0 %), the truck stalls out and sounds awful?

if its getting cold up there, plug it in and you could possibly consider changing to a lighter weight oil if it's going to stay very cold (i've never done this but have heard it works in cold climates). maybe look into lucas oil stabilizer on your next oil change... it's worth a try, i've had decent luck with it in my powerjoke, and so has a friend of mine with an 02 24V. for what it's worth.

D.Wiggs

I am definitely up for anything.

Some idle speed rattle is normal with Flux 2's in the 04.5-06 and up engine, but I am talking about mild, not anything that will make the engine shake or certainly nothing you can feel. Just a mild rattle at idle. Not cruising speeds.

Flux 3's will stop the rattle altogether and this may be something you want to do in the future. The good news is....it is not like buying a full set of injectors over again. They are upgradeable.

The rattle you are describing sounds to me like a double disk clutch. The vibration could be a pressure plate that is not perfectly centered on the flywheel. I almost think you might get away with a single disk FE clutch and still hold while having no rattle and much improved drivability.

Yes, the FASS is loud. Normal, although some dont like it. The Walbro makes much less noise.

Drone: I hate drone. I have it but it is much improved with the addition of the "water heater" It is a 51" long 5" in and out muffler. A resonator is the next step, but I honestly dont have much to complain about now. The water heater came from Rip Rook at Source Auto. Place all mufflers as close as possible to the rear of the truck. Having the shortest tail pipe section you can get away with will help much with drone.

Start up smoke in cooler and cold climates is normal with the 04.5 and up engines. Plug the truck in at night. It helps the rattle and shake until the engine warms up.

It is hard to refine a truck and honestly most of the performance market has thrown that part out the window is hopes of finding max performance.

Last night, around 2:00a.m. a drunk guy slams his Acura MDX into a parked BMW that was behind the Dodge and sent it flying into my Class 6 Hitch!

The BMW's front end was totally destroyed and hissing and leaking something fierce. From what I can tell so far, the only thing that happened to the truck was the ball mount was bent; but it doesn't seem to have done ANY damage else at all!

JD Dearden

Wiggs your truck is fine just turn up the radio.

D.Wiggs

Thanks Don, and the I love the Flux 2's. Is there any disadvantage to getting the Flux 3's. I thought they were not the best for towing and "bullet-proof" applications. Do you really think that a single could hold all this power. Once I have the SMarty on, and probably some water/meth or NOS, I would have to think I would be closing in on 1000HP at the wheels. How would EGTs be with that exhaust?

D.Wiggs

I don't have the sound system I want yet. I can't crank it though when the wifey and Dane are sleeping on long trips. I just want it to sound like a SEMI (even if it rattles at idle), not like the "shake you apart machine"!! LOL

Luken

LOL don't tell me you dont have a surround sound with 4 dvd screens in that thing yet

Luken

sound like a semi = you NEED stacks!
