Two wheel drive Duramax outpulls me

[Todd T]

our club met this past weekend for a test and tune day at a local sled pulling club's track. some of us were feeling our oats and tried our luck in front of the sled.



just for measure i wanted to pull my truck in the high side of the transfer case so i can see what my mods get me when i'm done. it should pull the sled silly in high once i get done. for now i have a stock transmission and just a few things done in the pump. pretty well stock. well... . i made it about 60 feet in first high with the automatic transmission begging for mercy the whole way coulda used some more fuel but those (370's) were on the front seat.



another member Mark Guebert, has a 01? Duramax LB 2WD. he hooked to the sled and pulled it about 75feet before giving up. he had it in 2nd and the transmission kept shifting back and forth 1-2-1 and he lost his ground speed. 75 feet for a stock 2WD truck is pretty good in my book. considering my mostly stock 97 4wd only did 60 feet.



good job Mark see you Saturday and we'll see that track again later, on my terms next time.

I'm pretty sure I would've kep'd that little tid-bit of information to myself. Don't need any far-out rumors gettin' started. Those Dura-heap guys'll start gettin' big heads.



Later, Rob

Just wondering? What stoped you? Did the engine die, lost traction, or stock converter let it slip?

 

[Mark_Kendrick]

OH NO!!!!!!!!!

Mackin's gettin the big head :-laf:-laf

what stopped me?? a 1997 stock automatic transmission with 232,000 miles on it.



lets see the Duramax do that!!



I dont care that i lost, i think it was funny. like i said before, i was just laying down the yardstick to measure my modifications by. these guys know me, they know i cant leave anything alone BTW have you seen my sig?



they were telling me i had a unfair advantage because i had my two year old in the cab with me



i just parked the truck and told them "mark your calendars boys, same time next year, all you will see is dirt flying and my tail lights. i have just begun"



actually we were just impressed with the way the rearend worked on the D max. they have some kind of electronic locker thingy, and its works

 

[MABurns]

I don't think there is anything electrical about the Eaton (G80) locking rearends in the GMs.

Pretty good explanation on how it works.

it is very unwise to pull a sled in 4hi and in 1st with the auto you will break an output shaft--been there and done it twice--so if you do it again in 4 hi be prepared---you're better served in 4lo and the transmission in Drive---just a heads up---chris

 

[Todd T]

thanks Chris, I knew that. good disclaimer for those that didn't though



the only reason i did it, was this transmission's days are numbered. in about a month it goes Bye Bye.
