power vs. stock drivetrain

[Redmega06]

I was wondering other than engine and transmission how much power will things like the stock driveshaft, rearend, frontend and transfer case handle

 

[Slow Six]

I would say it depends a lot on the right foot.

 

[Redmega06]

I understand about the right foot thing as I have a heavy one. I was wondering about the experience of those with the big upgrades like twin everything and big sticks. As that is what I am hoping to get for mine soon and I would like to head off somethings first and hate buying things twice

Most everythign I have read says the torque converter is the weakest like and starts to die around 700 lbs torque. On your stock truck that is what, a 50 lb increase or so? With your mods you could toast it easy I bet.

 

[BHolm]

There are plenty of guys here with 800-1000 lb/ft of torque. I haven't read any blown up drivetrain stories yet Lots of guys doing boosted 4wd dragstrip runs too, the trucks hold up well.



That said, it doesn't have "something" to do with your right foot, it has "everything" to do with it. I bet I could easily snap u-joints, twist driveshafts or tear up diffs on a stock truck. It isn't the power, it is how you use it. If you have a lot of power and a heavy right foot, you will probably break something eventually. Even minor mods put you beyond manufacturers ratings for the parts in question, so to put a number on safe power figures is impossible. If you wanna play... . expect to pay.

I would post this in the competition forum. I'm sure the pullers/drag racers have broken what will break.

You need to read some of Bobcat698's threads. lol Sled pulling issues. :-laf I think he's broke about everything once.

 

[SRadke]

Auto trannies and stock clutches are the weak points. Add a good dual disk to a manual drivetrain and it'll take anyhting you hit it with smoothly. It's the jolts that break parts.

I must say I am a little suprised. I figured that I would get a lot of messages about the driveshaft or transfer case. But I guess that if you don't hear about problems then there might not be any

 

[SRadke]

I'm not saying it isn't possible to do damage to transfer cases or rear ends but it isn't something the average guy does. Everyone I know who's taken out a transfer case or rear end is running near or above 600 hp.

There is a lot more carnage than what gets fessed up to here :-laf:-laf

I have a feeling that this is true. I am not for sure the power that I will end up with the things I plan on adding but I know that power and friends tend to make for expensive nights

 

[Bob4x4]

:-laf we have some interesting discussions around the campfire,trucks and fun don't come cheap

It's not the hp either, it is the torque Trucks over 600 hp are also well over 1000lb/ft of torque. That is just plain stupid power and could easily be used to break just about anything.

 

[betterthanstock]

With an auto transmission, it's almost impossible to break something else in the drivetrain first. (Unless you have a bad, rusty u-joint. )

It's the guys that drop clutches at 3000 rpm in 4wd, wheel hop, etc, that breaks axles and transfer cases. Also, pulling something in reverse will break your axle a lot sooner.

 

[KyleKlein]

I fried a torque converter in my last pickup with just intake, 120 hp chip, and exhaust, well rode it hard and put it up wet anyways so i went with the ATS converter which was night and day difference. Have you guys heard of any problems with running high speeds in 4 wheel drive? When Im at the track i feel like i loose power kicking out of 4x4 so i just leave it in and gettin up to arround 95mph right now.

 

[TCluff]

The 02' (automatic) with just an EZ, intake and exhaust has snapped three front u-joints! Each time taking the pinion yoke out with it! Also busted two CV joints on the transfer case side!



The 03' (standard) with twins, sticks, boxes, modded pump, etc... can snap axles just of an idle! Not droppin the clutch at 3 grand but tryin to climb over a car (gently ) snapped both front axles! No u-joint issues though! The AAM u-joints and yokes seem to be stronger than the dana's!



Both trucks are turnin 37's! How big of tires are you plannin on running?

 

[Redmega06]

I just have 285 18's for now probably not going much bigger as I am probably not going to lift it. Maybe a Kore for the ride. I am inpressed though finally some honesty. what car?

 

[TCluff]

It was just an old abandoned car out in the middle of now where! The 03' climbed up the trunk and onto the roof while the 02' climbed up the hood and onto the roof... Then the 02' towed the 03' home on a trailer... again!
