Regular Cab 8.1

BigJayDogg3 · September 22, 2007

O.K. I was talking with some friends of mine, and the topic of making a big power truck. I was thinking along along the lines of getting a regular cab regular bed to save on weight, and getting a 2500 with the 8.1, getting a free flowing exhaust and then, yep you guessed it, supercharging it, then getting a dyno tune. What I want to know is: what else could I do to get more power? Is this a good idea? All comments and suggestions are welcome.

I like this one. Carry on with the convo.

A reg cab short box 8.1, that would be awsome.

I like this one.

These new emoticons rule. Also would injectors be something needed with the larger amount of air going into the engine?

Yes you would need larger injectors with forced induction. I'd run a small shot of nitrous to go along with the blower/turbo. I didn't know regular cab short bed 2500's existed.

Edit: If your wanting to go F.I. your going to want to tear the motor apart and get forged internals IE. Crank, Rods, Pistons ect. Unless the 8.1 can handle forced air well, or your not running a lot of it. I'd save up 10 grand before starting this project.

8.1L are notorious at my depot for breaking crankshafts. We have 60 of these trucks with propane converted big block top kicks and once every other week we've had one go down with a busted crank lately. The mechanic was saying he doesn't know what's going with these things but the 7.4L never had these problems and they never drank oil like the 8.1L does.

If your going forced induction on a motor like this I would tear it down and beef it up if you put the larger injectors in there. Just my .02 cents.

Makes sense. I'm not actually going to do it, I was just shooting the breeze with friends, and though this would be a good idea for a "go fast" project.

As for the 2500 RC/RB setup, I think(about 80% sure)that I have seen a couple. But I am willing and able to admit I am incorrect about that one.

Also I know the 8.1 would prob. be better on the higher end of things, but what do you think would run better the 8.1 or the Dmax?

I've also seen water/methanol kits for diesels, what is that about? Why go through all kinds of trouble to keep water out, only to purposly introduce it?

EDIT: I just checked Chevrolet's site, and for the 2007 classic there is no RC/RB. I would have sworn that I have seen a few of them though. Oh well.

You could get a duramax to run alot harder for way cheaper than an 8.1, mainly because a $300 programer can get you over an extra 120 hp.

if you don't look at the $$, the DMax has been built by several people to the 1000+hp/tq marks. I think Gale Banks is getting ready to start selling 875hp crates. Along with send and return 875HP rebuilds. I haven't been able to see of the shows, on Extreme 4X4 they had a Urban Suburban project and stuffed a 800+ Banks DMax in it.

Yeah that thing is sweet, and it really pukes out the black smoke.

In the newest diesel power magazine some guy built a duramax that makes over 1000 hp at the rear wheels and he says he can get 1200 when he gets the turbos dialed in.

Since you just want to talk about sick diesels, the numbers weren't as high, but on Pimp My Ride, they dropped a D-Max into a Impala. While the color scheme isn't what I would have chosen, that car was stupid fast.

Sorry i got a little of track but I did see that car in a magazine... just think about following that car, and then to see it blow a bunch of black smoke. I'd be thinkin WTF, and pretty soon I'd think WOW, that thing is awsome.

Don't worry about getting off track. I threadnap all the time. I can't exactly get mad when someone does in now can I?

Bobslob · September 25, 2007

I guess this is the off-topic part... maybe that means you can just say really random things in a thread. somthing like, June 16th was 100 days ago.

BigJayDogg3 · September 25, 2007

O.K. I want to change this topic. What is your dream vehicle. I'll go first. Currently it is an 01-02 Silverado RC/RB stepside with the 5.3 and 3.73s. Preferably in the Blue Indigo (or whatever it was called then). And as long as I'm dreaming, I also want an International CXT.

Bobslob · September 25, 2007

My dream vehicle would be an 02' reg. cab long box 2500 HD with 6 in stacks and a Duramax built to a mild 800 hp, with a 6 speed manual. It would have a 6 in lift and some 37 in mud terrians.

Or a copy of copperhead, an awsome 67? C10 Stacey built on trucks a few years ago.
