1500hp 6.7 Cummins tare down, IT'S HURT

[@Fullerperformance01]

Looks like mine. I have D&J wrist pins now. 1450hp on cast pistons 🤘

Car guys must hate it when a big old Dodge truck eats every car at the track🤠

[@CUTTERUPROB]

Ya they hurt feels lol

[@elroyelblander6277]

👍👍 can't spend enough when a person wants to play I guess...idk anything about that 🤣👍👍👊

Ya know Rob, I don't like the way the top of the rods are "slash" cut. Haven't seen this on gas engines. And besides, with that weight and size of that wrist pin, a little extra weight on the rod small end is not a big deal. Looking at that bushing says there is too much concentrated loading

[@CUTTERUPROB]

All the Cummins rods are this way

[@bcbloc02]

If only Cummins used Deere sized wrist pins then they would be good till block splitting power levels no problem.

D&J Precision Machine Tool steel wrist pin, Is there any Canadian dealers. Dirty Diesel Custom showing them for $697.50 CAD. Not sure they stock them.

[@CUTTERUPROB]

I am a dealer for them. Just when we built the engine there was no stock

[@DFB-1990]

So that was orings and a mls head gasket? How much hp is a mls gasket and 625's good for before you should oring or fire ring the head? Thanks!

[@CUTTERUPROB]

Yep. I have seen them do 800hp easy on a 6.7. But I like to put a oring even on stock ones

[@frankalbergo8120]

Excellent, thanks. Have you ever run Black diesel at the track and what was the difference between straight diesel and the black?

[@ivonivan1169]

Its basically race fuel

[@ivonivan1169]

More btus per volume unit

[@TallGarage]

Good question
