Hey guys, this is my first post! ive been reading the forums all night, Great stuff!!! here it goes -

Going to buy a 04' superduty in about 2 weeks. All records show no turbos replaced or injectors and it has 159,000 miles on it. so i assume this isnt one of those troubled 6.0L. I have all ready planned to get a VOLANT air intake, Air Aid throttlebody spacer, and AFE 4" turbo back SS exhaust.

I like the volant, i put it on my buddys GMC and it was a awesome for a gasoline. Am i gonna get the same resaults for the diesel? i want to get a tuner but dont have enough $$$!

Is the throttle body spacer a total waste of money? (85$)

And is it easy to install the AFE exhaust system? Shouldi have a professional installl?

Thanks guys and if you have any low cost parts or mods to suggest for adding torque and HP let me know!

 

Okay, first off you are purchasing a diesel Not a gasoline engine. They operate differently. There is no place to install a "Throttle body spacer" on a diesel engine as there is no throttle body and air is not regulated on a diesel motor.

The OEM factory Donaldson Air intake is the best thing going in terms of filtration and performance until you reach 500+RWHP and that takes more mods than just a tuner and exhaust (ie injectors etc). So stick with the factory Donaldson Air intake.

As far as exhaust goes MBRP & Silverline are the two most popular with the 6.0 crowd. An exhaust will reduce your EGT but you will see no Hp or performance gains. A Turbo back 4-inch exhaust with 3.5-inch down pipe will lower the EGT the most. A Cat back 4-inch exhaust will lower the EGT as well just not as low as a turbo back system.

Anything bigger than a 3.5-inch Down pipe and 4-inch exhaust is a total waste of time until you reach extreme Hp & Torque numbers. In fact a larger down pipe and exhaust will hurt performance on a stock or lightly modded 6.0 as it raises the power curve.

A inexpensive way to achieve lower EGT temps is to straight pipe the factory system with or without the CAT left in place. Basically cut the muffler off and run a piece of 3.5-inch pipe out the back.

The cheapest way to increas Hp and Torque on a 6.0 is with a tuner & custom tunes.

The SCT xcalII/III with Custom Tunes from Matt at Spartan Diesel or Eric at Innovative is the way to go ($450).

Along with a tuner you will want to install A/M gauges as well, EGT, Trans Temp, Water Temp and Fuel Pressure at the minimum, Boost is nice to have but not mandatory.

 

ok that sounds great, guess those guys from super trucks dont really know what their talking about :-/ Ill be giving matt a call soon, he seems to be quite popular on these forums and probably for a reason! thanks

 

Well if they were telling you to install a Throttle Body spacer then run fast and far away from them.

Also when you get a chance read the 6.0 tech folder there is a lot of good info in there on basic maintenance etc and the 6.0.

ps- great advice blackhat620

 

Blackhat620 got it, stay with the oem intake most threads will say they are good for up to 500 hp, and of course cant use a throttle spacer, so that frees up roughly $400, so get a tuner from spartan and exhaust, some gauges and your set.

 

Only thing I would add is get the gauges and exhaust upgrades first. Only then would I get the tuner.

 

K&N claims somethin like 15 hp for there cold air intake, so are we sayin very little improvement on performance, or just not enough to make it worth the price?

 

Key word here is "Claims" made by the manufacture selling their product. You will see No performance gains by installing an A/M air intake on a 6.0 producing less than 500+ RWHP. You will see increased wear on the turbo however buy installing an A/M air intake like the K&N that filters less than the Donaldson Powercore. Of all the A/M air intakes K&N has the worst reputation.

The OEM Donaldson Powercore provides more air than the 6.0 can use until you modify the engine to make more than 500RWHP. Bottom line an A/M air intake on a stock or lightly modded 6.0 is a waste of time and money as no power gains will be seen. This has been thoroughly tested by the guys that heavily mod and race the 6.0.

 

Ya i was planning to put the AFE exhaust on first. i got SS turbo back for $389! the MBRP is a little outta my price range for the same system. I figured it would lower EGT and help keep everything running a tad cooler with the tuner. Is it worth the extra $ for the livewire? or just stay with the XCALII?

 

XCalIII and real gauges is a better investment. That seems to be the consensus as the livewire has been known to have problems, although they may have them worked out. Give Matt a call as he'll have the latest word on the Livewire's.

 

I also have an AFE exhaust and I like it, it's held up well. Pretty much everything else has been said, just wanted to let you know someone else had an AFE exhaust and liked it thus far(turbo back, don't have the cat but I do still have the muffler, although it is a high flow one and it makes the sound I like so I'll keep it there).

 

actually blackie, our 04's DO have a throttle body, and they DO make throttle body spacers for the 6.0, actually all of the 6.0's have a throttle body, but i believe only some 03 and 04's actually had the throttle valve in them.

adding a larger downpipe is indeed a waste of time and money on a lightly modified truck, but it will not hurt performance.

as far as a tuner, yes listen to blackie and go with the SCT. gauges for an 04 you will want at minimum : boost, pryo. if you tow then consider a tranny temp gauge. the 05 up came with a factory boost gauge

 

actually you guys with the newer trucks have different parts than us. Yes the 04 does indeed have a throttle body. i know it sounds weird. all of the duramaxes have throttle valves also. it is a smog thing has to do with the egr mostly.

they do sell throttle body spacers for these motors. but most people just buy an aftermarket "power elbow" and order the 05-07 one as it is longer and eliminates the throttlebody on our motors.

 

Thought i was going crazy reading about buying throttle body spacers for 04' 6.0's . Thanks for all the help guys, you sure saved me alot of money and helped gain me some HP and Torque! soo i guess in conclusion, you guys r the best mod! haha
