Blow a headgasket or shorten the rods?

The famous stack, Juice Att, Quad 215, Nitrous, 100% methanol. Look in the drag racing and truck pulling forum.

Found it... Seems like the rods seem to be the weekest point when the Duramax is pushed to the extreme... The bottom end seems to have proved itself plenty strong and I don't believe the connecting rods are going to limit power either like they did on some Powerstrokes. Time to throw in some stoughter rods and see what breaks next... maybe also some custom valvesprings so that the RPM limiter can be raised higher

I would be very surprised to find that the rods were not shortened from a hydraulic effect. I’ve seen more than my share of broken engines. Sounds like the cylinders had more liquid than the quench area would hold. I’ve seen a few Carrillo (some of the strongest in the racing industry) rods bent in Sprint cars from the same thing.

How did you get all the aftermarkets off without the dealer knowing and or finding out, especially all the codes? Just curious for future reference incase I have any trouble.


Thanks

Codes can be erased with the Quad Stealth, Predator, and Power Pup. Everything can always be taken off and put back to stock, except probably his transmission.

If you blew yours up only making 575hp, how come heartburn canada can make 675hp without blowin his up? Something smells fishy...

Nobody's calling anybody a liar. 20 people witnessed GotJuiced put down 550hp. With a couple of modules and a stock tranny. Never did back it up. But to this day, I still DO believe that the dyno said 550hp, and 20 people witnessed it. Never doubted that, but I'm sure the dyno was in error that day.


Fill in some details. What did heartbeat stack, what kinda dyno, did he back it up on a different dyno on a different day? Can you explain to me how one engine can blow with 575hp and another one makes 100hp more with no damage?
