duramax vs 8.1L Big block
 

A guy i work with has a 02 2500hd extended cab 4wd w/ 3.73 rear ALL STOCK and swears he can leave me towing or racing. My truck is a 03 4wd reg cab w/3.73 rear 4" exhaust K&N intake and a Hypertech 90hp programmer! He keeps wanting to race for pink slips what do you think?

well I wouldn't do it cause I don't know, I can't afford too lose my truck, if you had EFI Live or just a PPE i'd try it, but for pinks, hell no, just wager like $100 or something that way it sucks for one of ya but you're not out of a truck:c:

yeah I cant afford to loose my truck ether. I have tried like hell to try to race him for fun, or money. but he wont. it slmost made me think he had NOS or something. but i poped his hood, and looked under the truck and it is all stock, he is just real proud of his gasser

tell him that the only reason he wants to race for titles is cuz no one actually does that he is scared

sounds like he's a few marbles short of a full jar, I sure wouldn't do it, i honestly think if you can hook up you'd smoke him, especially with a little boosted launch, but lets say something breaks or whatever, then you're out a truck and yours is more valuable in my opinion than hsi anyway just because of the diesel:U:

Just tell him if he really wants to race put up 100.00 or shut up. To many things could happen that might change the out come, plus I really wouldn't want to take a truck from some one who can't afford it.

i think on top end he would get me bc my truck cutts off at 98ish

so does his if it's completely stock and if he said it goes faster than 98ish he's full of it cause that's stock governor on chevy's

Those 8.1's can move. Esspecially if he has a good programmer on it. GM pulls ALOT of power out of the tune from the factory. I would be careful!

lookin under the hood wount show nothin if there is a programmer on that gasser but it is your truck so its your call id run him for braggen rights and money or a nice dinner for the family winners choice.

damn if you were close if slip in a little tune on that truck :D

x2 on tell him to put up some cash or shut the hell up.

:booo::booo::booo: not worth it even if you could beat him he must watch the show pinks and has an ego the size of texas.

Don't do it, check out the june issue of diesel world. The 8.1 is a monster. def get efi live or ppe before you mess with that sh t biscuit.

just an update. I did not get to race him bc he traded it in on a nissan altima! LMAO

Well thats funny!! I had a 8.1 for about a month after my powerstroke was stolen and it hauled ass. It would burn the tires at a light and it was stock. I raced my buddies 6.0 with a edge in it and i beat him with my stock 8.1.....

no replacement for displacement:tu:

holy shi--.....They're honestly that fast? They're at 340hp 450ft-lbs of torque IIRC...I thought the duramax or a powerstroke would be able to trump that. Similar horsepower but way more torque.

I think it is the fact that they dont have to wory about turbo-lag. I cant wait to get my PPE! Hypertech=sucks

The 8100 (thats 496ci!) gasser can be absolutely brutal with some tweaking. Keep in mind the marine versions of it are rated as high as 500hp! That's in a factory engine with a warranty! The power is there. It's all in the ECM tuning. Buddy had one in a 2500HD with the 5-spd manual trans and 4.10 gearing. Everything stock except a straight-piped exhaust and he could get rubber through 4th gear.

LOL....wow! I wish I could see that.

Funny now it's got me thinking of how cheap those 8100's are going for...$9000-$11,000 with low miles just because no one wants a 7-9mpg gas sucking beast. :humm: Would be a fun truck for sure.

His was a 2001 Reg cab 4x4 with 79,000 miles on it. Said it got 8mpg loaded or not. Sold 'er for $9500.00 and bought a 04 PSD that coughed-up it's HPOP the 2nd day he owned it.

Figure all the 8.1L is, is a stroker 454 big-block. Drag racers have spent a lot of money for a lot of years to get that kind of displacement from their BBC's.:tu:

Man, my friend had one of those 8.1s. His was prob a 2002? He installed exhaust, CAI and a Hypertech. It was a reg cab 4x4 with an auto. Even after all that work it was a major pig. Id have to see another one that ran good to change my opinion. I bet the D-Max would whoop it pretty bad.

wish I had a answer....It was the race that never happend LOL.

I dont know.... it would be close... Mine was a 02 ext cab long bed with an automatic (Which happens to be the allison) I got it at a chevy dealership that was selling there repos they got back. Only paid 5,900 for it.... should have kept it

maybe he's just flabergasting... since the "pink slip" isnt actually pink, so ok and get a pink slip of paper. wire doen ":edit: you" on it, and win.. see what happens... either way, he didnt specify

The 8.1 is a design of its own, It was used as marine engines before making its way to teh trucks.

Yeah the 502 was a crate motor, I thought that's what the 8.1L Vortec used as a block.

we got a bunch of them 8.1 at work and they haul man, i wouldn't toy with one of them. they pull awsome too. we have them in 2500,3500 singles and two 4500 box vans, and they ride like a dream. and also i got a new chevy gasser 6.0 and don't seem to have a problem gettin over 98 with it.:w2: only done it a couple of times gets kinda scary with the utility box i got on it.

I drove a 8.1L with the Alison auto 1 time. It was a crew cab 2500 and I believe it was a 2002 model. I don't really know much about them but I was disapointed with it. I honestly thought it was a dog.
I have a hard time believing a stock duramax couldn't take it.

Forced induction...

a big inch rat motor with tons of nitrous will beat your forced induction engine any dayof the week. but what can i say both my vehicles that i own are forced induction

ive seen a EFI live tuned 8.1 run a 13.3 in colorado. FYI
