Haha im the first. I will post pics of the ginormous truck i have been working on. We are also doing a project for a guy this month that wants to build a 900hp Powerstroke Ford. :worshippy

Damn, 900hp? Definitely post some pics and info about that one.

that just doesnt seem like a whole lot for a diesel...
Should have a tq of nearly double that!

My 15 second 7k lb. truck only made 420 hp. It also made 795 torque. So when this truck is done it should have in the hood of 1500 torque.

That's a hell of a lot of HP for a diesel. They make FAR more torque than hp.

Youre right... I just always thought the bigger newer diesels made like 5 6 hundred hp with minimal mods.. but that was tq.

Nah, it was fine. I had a kit in it.
Here is a pretty cool dodge here in Arvada.

Can someone explain to me why truck engines peak in power so early?

You mean to tell me a Cummins diesel 6 cyl is a big fuckin motor? ;ScratchHe

diesels naturally are made of iron not aluminum like honda blocks... And have high ass stock compression compared to cars...

cummins 6.6lt is a v8 I believe!

My brother had one, it was a 6 cyl.

well even the IL6 older diesels had like a crazy compression of like 17.5:1
My question is, how are they so high compression, yet they handle sooooo much boost?

still 2 cylinders have more displacement then an entire honda engine!

hello iron block > aluminum block!
Same reason crazy people with dart blocks can run 30 + psi all day long.

Its the nature of the diesel. Diesel doesn't have a spark plug and is a self igniting fuel. It needs the high compression to heat the air charge to a temperature that will ignite diesel fuel on contact. When the piston is on the compression stroke there is no fuel in the cylinder, only air. At the point where a gas engine would light a spark plug, a diesel engine begins spraying fuel directly into the cylinder causing the heated air charge to self ignite. This is whey they sound like a preigniting engine all the time. Because they are.
All cummins diesel power plants are L6 designs BTW. Only International (powerstroke) and Isuzu (duramax) engines are V designs.

I thought Darts were aluminum too?

I agree with everything other then your last comment about L6... the new 2500 sierras are v8 cummins diesels 6.6lt

You sure about that? Sierra = GMC, Cummins = Dodge

not sure... but they are completely closed
I assume cylinder reinforcement helps alot!

I stand corrected and look down in shame... i meant duramax

Dart blocks are still aluminum blocks with steel liners and closed decks. Not steel.
And yes you should be ashamed. Cummins= Dodge Duramax (isuzu)= Chevy GMC International harvester (Powerstroke)= Ford

It's a diesel engine they don't have enough time to burn the fuel at high rpms, hence they peak early. Also, in the case of trucks their rotating assemblies are way too beefy to rev. Finally, these trucks are designed to tow, not race. So everything is built for low end power. You can get a diesel to make power at the rpms gas engines turn, you just have to run insane fuel pressures to get the droplets small enough so the burn is fast enough to have the engine make power up there.
Dart's are aluminum solid decked blocks, Conrad. And Duramax is still GM (Chevy).

Not only that but try to spin a rotating mass weighing over 250lbs. The rod stroke ratio of a diesel is pretty ludacris.

It's GM, but its built by Isuzu.

Dodge 2500+ diesel is manufactured by Cummins
Chevy/GMC Duramax diesel is manufactured by Isuzu
Ford Powerstroke diesel is manufactured by International Harvester
None of the big 3 manufacture thier own diesels, which is probably a good thing!
I'd rather be Cummin for a minute then Strokin all day.
HAHAH I'm awesome.

The main reason a diesel doesn't self destruct under boost is that in a gas engine, detonation is your ultimate enemy with boost/n2o/etc etc. The diesel runs purely off of detonation, so the parts must be able to handle the abuse constantly, so a bit of boost on top of detonation leads to extra detonation, which the diesel likes. Plus, most diesels redline under 4K, so they have to make tons of power lower. Spinning mass also helps with keeping power in the lower RPM band. These things have incredible inertia when they get spinning.
I'm going to put TDI Jetta pistons in my next car.
