12 second duramax turbo diesel

I’m at the street drags and I watching some of the competition in the pits. I see a red Chevy that says dura max pull up to the line. Holly crap was that thing fast. I also thought his launch was comparable to the syclone. I overheard talking in the pits about how that Chevy dura max ran 12's. It must have been one of his buddies.
I later walked back to my truck and who do you think was blocking me in? The red dura max turbo diesel. I asked him to move but he said he only would if I raced him. I said "sure." I was a little intimidated by his truck because I have never had mine to the track to even know what it runs. I think I gave him some cold feet as well. He wanted to know my mods. Of course I told him "Im stock." And of course he told me he only runs 13s. You know how that game goes.
I get up to the line and he starts pluming clouds of black smoke out if this exhaust and I can’t even hear myself think because his turbo was so loud. All I could think about was launching hard and watching for that green light. I pulled a quarter car on him off the line and then ended up pulling a full car on him as I crossed the finish line.
I could not believe it. I won by almost two car lengths. I really surprised myself. Little did I know that I was about to surprise myself even more that night.

I beat:
Pontiac with a 455
AWD eclipse with a front mount
Mustangs
multiple v8 trucks
and even a guy running the same exact drivetrain as a syclone (AWD, with 700R4) bolted on to at 327 small block in a 91 S10.

Re: 12 second duramax turbo desiel

there are plenty of them runnning 10's now. so be careful what the owner tells you, they can be made to be really fast even on stock turbo.

Those type of trucks are my all time favorite to smoke, they get a bully-dog programmer and think the trucks C6 Corvette fast, lol.

A friend of mine has his DuraMax running 6.0's in the 1/8th, which is about the mid 9's in the 1/4 and he drives it on the street all the time. I am not sure if he runs straight pump diesel or has propane injection. Either way, that's flying!!!!

Very, very nice! You really cleaned house, didn't ya!? :D

If I would have known it would be such a gas I might have made the trip. Then again I spent the weekend working on pulling my head so I was kind of tied up. Are you thinking of racing again?

Im not a fan of the big trucks. I know there are some out there that are fast but for hte most part, around here anyway, they talk a lot more shit than they can back up. Only time I ever raced one at the track was when I was leaving it in 05 and saw a Duramax launching in the dirt. It was a pretty smooth dirt road. I figured what the hell and I challenged him to a race. We raced right there in the dirt. He launched in 4WD but I still got a car or two on him out of the hole. He never even came close to recovering. We raced about an 1/8th in the dirt and by the time we both let off I had 3 cars on him. This was when I had my stock turbo too.

I want to head down there again. Its a lot of fun. Its only $10 to race. The only thing is I have to take off work to race on a Friday. I work second shift.
Tooky your truck would be the fastest thing down there by far. Trust me there are some fast cars but nothing I could see would be able to take your Sy in the 1/8 th mile. unless you wanted to race in the pro stock class. Some of those guys had wheely bars.
LOL if you were to come down I think I would end up racing you. And every time people seen a black syclone show up they would probalby just go home :rotf:

You can't extrapolate 1/8mi times for a diesel truck like you can a car. They seriously lack top end. Even so a 9sec street driven duramax would be pretty damned famous and I have yet to hear of one that isn't a full blown race truck.

Re: 12 second duramax turbo desiel

Yeah, the guy said his 4th gear really sucks in his truck. I belive it because I started to pull on him towards the end. Either way he had to be making more than 400 hp to get that big truck to move as fast as it did. I give him props.

Re: 12 second duramax turbo desiel

my daily driver is an 07 crew cab 4wd Duramax, and it ran 12.70's first trip to the track. That's with my tuning and a different exhaust, no motor or turbo mods. For a 7000 pound truck they can be impressive for sure.

I still wouldn't be out racing Sy/Ty's though, pretty easy to get your stuff quicker than that. But for what it is, and 21-22 mpg on the freeway I'm happy with it.

So do you just buy a chip and you instantly get into the 12's or what? I have heard of propane injection is that what your tuning?

If he's tuning it himself its EFI Live. And I doubt that hunk of shit allison behind that Duramax is holding up to 12's without work. I'm losing respect for GMs HD trucks. First IFS, now no manual tranny option. Those duramaxes are damn fast tho. Nice kill.

Re: 12 second duramax turbo desiel

That is why I said "ABOUT" when I "extrapolated" the ET. I know that trucks are not aerodynamic high speed drivers. However, here is a link to the track where you can get the straight scoop. I guess you might want to keep you ear closer to the ground, so you can hear more. Any chance your name is Dennis?

No, using EFI Live to tune, no propane. It's not instant, at least in my case. Took a lot of tuning and datalogging, finding small increases until they all added up to where I am.

I wouldn't call the trans bad because it won't handle 50-70% more power and 75% more torque than it was designed for without needing some better parts. That's a lot to ask for out of any trans. They just don't engineer that much extra capacity into them, no need.

Mine is fully built for the power level. There have been guys into the 12's on the stock trans, but would imagine they're on borrowed time.

The kills section lately sure has been blaaaa. Start getting your trucks out of the garage guys.
