6.0l performace

[olliepop2500]

i was wandering what else i can do to my 2000 6.0l 2500 to get alittle more power. i have full exhaust and cai. i know a programmer will help but i was looking more. Im not a machanic in anyway but my dad is but i was looking to see what you guys got that i can do to mine. i was think cam maybe a turbo or supercharger but i dont know what ones are better then others. Just trying to het info on the subject.

thanks oliver

Forget the programmer, go with a custom tune. A nice cam, higher stall, lower gears, longtube headers(you say full exhaust but know what your running).

Bingo.

Tune, cam, converter, gears, headers out to DI/SO exhaust of your choice. If you want a bit more a P&P of your heads and TB would eke out a few more HP. Aside from that, the next mods are heads and pistons, and beyond that, forced induction like a SC or turbo.

[olliepop2500]

i dont have header but i got true duals flowmaster 44s. i know a custom tune is what i need but i got to find somewhere to get it after i do somemore upgrades. Do u know where to get cams and a higher stall. i was think on a trick purformance turbo kit for it after the cam and what not.

[custm2500]

A tune alone will make it like a whole new truck. Then if you add a stall you will be content for a good wile. A tune and convert should take atleast a full seccond off your 1/4 time and most of those gains will be felt stop light to stop light.

After you get those done then decide if you want more. You can have the two done for $1000 if you install the converter and I highly doubt you will feel the need for any more atleast not right away. Plus they will both lend them self very well if you decide to install a cam, or forced induction set up!

[olliepop2500]

so u guys say tune and stall first. i never took my truck down the 1/4 but i can tell its sluggish when i put bigger rims and tires on so i want to get alittle more.

Dual Blowmasters is NOT the same as a proper LT and SI/DO setup. In fact, the "true duals" (God, that phrase makes me want to puke/murder) are probably hurting your torque curve, it's too much flow for the 6.0L. There's a reason it comes factory with DI/SO.

Cams, stalls, etc. can usually be ordered directly from the manufacturer, however there's a ton of sponsors at PerformanceTrucks.net that carry both, as well as big-box vendors like Summit.

Re-gear to make up for the larger wheels and tires.

[olliepop2500]

i dont think its to much flow i have a 2 1/4 in exhaust after the mufflers. i think its 3 into the mufflers whatever it is from the factory. i already have 4.10 gears

[DarkCharisma]

It's too much flow.

Go deeper on the gears if it's still a piggy. The 4L80e has a tall first gear that doesn't lend itself to quick starts.

Yes, you will be amazed at the change. The drivability the comes from a tune alone is massive. The performance gains are solid from the tune, and a converter is a constantly proven upgrade.

[olliepop2500]

what stall coverter would be good?

[mainechev]

i already have 4.10 gears
What size tires are you running? If you have 35's or larger, 4.10s aren't low enough IMO

[olliepop2500]

they are only 305 but i can tell the differents from when i put the stock wheels and tires back on in the winter its got alot more go

[MrMobley]

305/?/? What's the full size..?

[olliepop2500]

305 65 r17 micky thompson atz factory is 245 75 r16

[MrMobley]

So you're just hair under 33" tires so 4.10's should be plenty low enough.

[DarkCharisma]

Not on 35's with a 80e, they aren't. I had 4.10's on my 2500HD with the 6.0L and it was a dog. He needs 4.88's.

[mainechev]

:iamwithst

[olliepop2500]

if i got 4.88s then it would probably suck driving on the highway then right?

[MrMobley]

I'm forgetting he's in a 3/4 ton. Wouldn't a 4.56 be fine for his 33's in the same truck as yours on 35s?

[DarkCharisma]

Depends on what you consider "fine..." My truck did okay with 4.10's and 37's for a while, and the 35's were a bit better, but realistically I'd rather turn an extra 200RPM in OD when I'm on the freeway than deal with having to balls before 40MPH.

[olliepop2500]

so your saying i should just get gears for get the other stuff? im deffinetly getting a tune

[DarkCharisma]

Tune and gears would be a very, very nice and very noticeable change.

[kemble]

Im not exactly sure of your goals? That would make advice easier to give.

[olliepop2500]

im trying to get more power its sluggish. i would like it to be quicker im just trying to get the basics done first. in the end i would like to turbo or supercharge it but what to get some info on what to start on the get more power.

Start with the aforementioned two. (Tune and gears) Then move to a cam and stall. Should that not be enough, you can look at forced induction as a serious option, but be prepared to spend a minimum of $3000 to have it all done.

[kemble]

Well you need to have a plan. Buying speed parts 2 or 3 times because of improper planning is no fun and a waste of pocketbook filler.

i found this turbo kit and i dont want to put a turbo on my truck without doing alittle upgrading before it.
yea im trying to make a game plan for it

[kemble]

I don't understand, if that's your plan what else are you after? I personally if going FI on your truck would Install a shift kit, good converter, big cooler, upgraded fuel pump, bigger injectors, then simply get a good custom tune. Then enjoy.

[olliepop2500]

ok i want to end with the FI but i was trying to find a place to start. im not going to beable to buy it all at once so i need a place to start.

[MrMobley]

So start with gears and a tune, and then start picking up everything you need after that and install what you can as you can.

[olliepop2500]

that was my plan i just wanted to know where the best place to start at

[MrMobley]

As far as things after tuning and gears...?

[olliepop2500]

whats a good cam and coverter?

[kemble]

I wouldn't put deep gears in it if going turbo in the future.

[nick613]

I'd wait til you do all your performance upgrades before the re-gear. 4.10s should be fine, 4.56 might be a bit better but if you are going to do cam, heads, stall, shift kit, FI and a tune it'll be a totally different animal

[DarkCharisma]

I wouldn't put deep gears in it if going turbo in the future.

Even the diesel folk re-gear, and it's a ton more power than his 6.0L will ever see.

Chad that's an apples and new York strip steak comparison. His gas engine will need some load to put the turbo to use.

[custm2500]

You people and gears kill me. He is less then 2"s over stock height tires. You can gear all you want but it isn't going to make that big differance. Just to let you know I dropped about 2"s of tire going from street tires to my drag slicks and guess what. I didn't drop anything noticable in my 60, 330 or 1/8th! It was effectively going from my 3.73s to almost 4.11s.

You can get gears but don't expect anything compared to the gains from a tune, or converter.

[DarkCharisma]

Chad that's an apples and new York strip steak comparison. His gas engine will need some load to put the turbo to use.

If he's still running something close to a 34"~ all-terrain, I'd venture there'd be a good bit of load to begin with. This whole discussion *might* even be moot anyway. Let's be honest--how many people say they're going to turbo, and never go for it? At lest this way the guy would enjoy the hell out of his truck for not a lot of $$$.

[kemble]

Less than $400 and he could have a 100 hp of nitrous. Docile truck , until more power needed.

[olliepop2500]

im deffently not putting nitros on it. so can anyone tell me a good coverter and cam to go with

[custm2500]

Converter you will want to stay 2600-3000. Yank, PI, circle D are good.

A cam you will want a smaller cam. Something with 220/220 duration at .050 lift. If you want your best information on a cam check out performancetrucks.net. There is much more peformance geared information over there.

[olliepop2500]

ok thanks im goin to start ordering a converter and prabably a shift kit why im at it. then im goin to get more info on the cam and order one of them
