Does anyone stroke diesels like gassers?

the biggest reason to not want to want to spend the big bucks for stoker kits is because for any added hp or torque that would cost you thousands you can gain by adding a bit more fuel and or air in one way or another for a lot less $$$$

who in the hell pays 10k for a stroker crank or 7k last time ichecked with a local shop the total price was just under 4k billet crank

People that are pushing the envelope, living on the bleeding edge, and want every advantage they can get.
 
The people running stroker cranks, etc. aren't telling you they're doing this.
 
Ok thats what I figured. Stingy bastards lol

One thing I never understood, if their competition already knows they are stroked, and all the other little secrets, why hide it?
 
My guess to why they just don't come out and say exactly what they have done even tho people know what they are doing is probably just because they want to leave some speculation. It's just that little competetive edge that they think they have if they stay real quiet about what they do exactly.

If you use a 6.7l crank, why cant you just build a spacer for the head to clear the pistons? When I put a 6 mil stroker in my quad, I just spaced the cylinder up. I figured you could do the same thing with the cummins.
 
You probably could, but you'd need a lot of skill or a machine shop to build it for you lol

This isn't CF. Most everyone on CompD has the capability to make one or two phone calls and have a deckplate cut.
 
Wether people are spilling the beans or not about it, it does not seem to be a big advantage or power gainer on the duramax.

Oh snap!

This is assuming you know everyone that has done it.

More displacement isn't just for power. It also helps spool big turbos. There is no replacement for displacement.

No i dont know everyone that has done it, but i do attend plenty of sled pulls, and i do know people that DO run them that i have ran against. Maybe without and inducer limit you would see more of an advantage. You can spool plenty big turbos with a stock cubed dmax when everything is right.

If there was no replacement for displacement the 7.3 powerstroke would be king of the hill.
 
I see the benefits more for a drag truck... Especially because of the open turbos. Yall can spool some big uns for sure.

The 7.3 isn't king of the hill?LOL

Why have a deckplate cut, when you can just mill the piston down? Assuming your piston has the material above the top ring groove to do that...
 
Wouldn't a deck pate allow more displacement considering you can only cut a piston so much?? I personly would love to have a stroked motor but right now it's not in the cards.

Yeah, I definitely don't have the tools to do make one. I don't know anyone personally that has them either. I can have a shop in town do it sure, but thats what I was talking about when I said have someone else do it.
 
um i think ben miller proved thier was no replacement for displacement when his truck came out and was putting it on kent, terry, chris, and curt/van. when running equal fueling systems and unlimited charger the 7.3 was on top for a while. Travis

You really don't need to cut a piston very much to get a healthy jump in cubes if shes being stroked.
 
I believe there is a happy medium of displacement and turbo size. With many hours of research and testing, im sure someone with proper funding could come up with a physics/calculus graphical analysis with displacement/ turbo size/ horsepower/ torque relationships for various engines ie. I-6 and v8's are different animals.

Here is what I am getting to... a 2.0L diesel engine with a 2.6 charger will make less power than a 5.9L with a 2.6 charger, so more displacement = more power, right? how about that same 2.6 charger on a 16L diesel? The 16L diesel will be damn near naturally aspirated with such a relatively tiny charger. So at what point does the replacement for displacement become air compression? If I knew the answer to that, I wouldn't be digging holes for a living. haha! I would be interested in any input or additional comments on this train of thought. If I am blowing smoke feel free to call me out, I'm just thinking on a keyboard.

This is only really to be considered by pullers trying to get as much power as possible with a limited turbo size because if turbo size is not a restriction, bigger is better for displacement and turbos!

So do you think the rest of them went up in displacement since that doesnt seem to be happening anymore? If not, then he didnt prove anything about displacement.
