more torque

[Brianedwardss]

Welcome back. Again I know what 3.31 and a C6 is like to tow with. Our final drive ratio is still much larger than Gary's (Icanfixall) or even stock overdrive trucks. (3.31 with the C6 'slip' in third gear is exactly the same final ratio as a 3.55 truck with e40d locked in 3rd, or a clutch.) The difference is first gear for us is a bit tall for getting off the line quickly (and cool temps).

Hopefully the group can fill in the blanks. Assuming you'd like quite a bit more power, isn't the C6 gonna be the limiter in the equation? I ask because when it comes time for a hill, my NA IDI that has a ZF5 looses much less speed than my 88 C6. The ZF5 truck just seems to harness all the engine power, while the C6 seems to slip a bit more, loose speed. The C6 is a great tranny, but I've never felt like they were really meant to handle more than maybe a mildly turbo'd IDI.

How about a 'Typ4' factory Turbo, Typ4 injectors, an IP from Mel, and head studs. Without a clutch or a locking converter, I think that's the limit (not a bad limit, still would be night/day from N/A). I'd like some opinions from the group on this theory.

I got these here cams,

 

[typ4]

you can build a c6 to handle LOTS of torque.

Nothing off the shelf or modifications will give you that torque reading. Sorry to say that too. These bottom ends can handle anything you can offer them but we in this idi world are limited in what can be done with these engines... Read what I have done to my engine. I still don't know what the torque and hp is but I wiil someday. I would not feel right posting that I feel like I have 300 hp at the rear wheels either. The fact is I have never posted any thought about this till now. I have seen other rigs making 202 hp with very little done to the engine other than a turbo. We do have some very nice hp numbers done a few years ago that were posted here. I do know my rig can easily run 85 mph in double overdrive with 3.55 gears and not strain at all. I have a gear vendors and with that my final drive is 1.96... Here is a dash picture showing these figures....

Gary that picture is sweet. I would love to have mine setup like that. I hate these 4.10s but at least I do have OD. I know on the interstate I could be running much more efficiently though.

500# at the flywheel is more than enough, and over drive, my Duramax is factory rated at 520, open exhaust is all I've done to it, it doesn't really having a problem towing the first 10 tons although it started to struggle a little the day I hooked it up to a 26,000# trailer by accident.

500 is very attainable with a turbo and fresh IP/injectors.

wow thanks guys, i didnt think 700 was that hard to get . i think the other brands 5.9 inline 6 can get 700 with just a few screws turned, hehe. anyways i guess im gonna just live with what i have again. thanks, mike

Get some gears and a OD trans or Gear Vendors.

Good idea

Riotwarrior we need more pics of the avatar ASAP!!!

If I had more of my wife that I could post as my avatar, I would just the ones I have...well ya not going to happen sorry

Mudduck... Thats not an oil pressure gauge... Thats an idiot lite with a pointer.... Heres an oil pressure gauge.... when it works....

Gary, nice lil gauge panel you got there.

5.9 cummins will not get 700 ft lbs with just a few turns of the wrench and last very long. do you realize how much torque 700 is? not trying to be rude but I just hate that every cummins owner thinks they are layin down numbers like that.

 

[Brianedwardss]

^ So true

 

[dyoung14]

Gary i want a gauge panel like that! make me one

 

[mudduck]

those are some nice gauges , ill stick with my dummy sticks though , they haven't lied to me yet.

They'd rather be ****** than strokin so they get to that real quick...their wives aren't so happy.

My old 6.9 NA is ~350# with a banks stinger kit, it'll do anything I ask of it, just might be a little late for dinner. The 460 was a touch over 400#, I had to be careful I didn't merge on the freeway over the posted speed limit when going up hill with a head wind and an 8,000# load, the piece of chebby factory rated at 520#, oh gawd, really? Do I need this? Why are they making 700+ on the 2011 trucks? Really? Do you need to tow both sides of your double wide at once or something?
