482hp 6.7 Cummins Turbo Diesel Dyno

This is my buddies 6.7 Cummins Diesel. We had a small dyno day at SkyTower in Stanford, Kentucky yesterday, and his 6.7 cummins was the highest hp truck there. All the mods are listed, except he tried out an MP-8 on 1 or 2 of the runs. Horsepower stayed almost identical, but the torque jumped up with that added in. This truck still has the stock turbo. All the EGR and stock exhaust system is also gone.

has this truck had any head gasket issues yet with the MP-8?

@QuicktimeGT Yes, he had some head gasket problems with it. Not sure if he had the MP8 on the truck then or not though. I dont think he had the MP8 on it when he blew the stock gasket.

Ahhh Didnt notice the injectors. lol. When my 6.7 gets out of the shop today I am puttin my intake TBE and XRT on. Ill prob be settin pretty nice there. Gonna do the deletes too but ill just unplug for now. Ill clean the map sensor too maybe the intake horn once I start pulling stuff off to do the deletes. That truck sounds great though.

Yeah, they run good. Unfortunately the head gaskets dont seem to put up with too much abuse and it doesent seem like there is a clear cut fix for that yet. This truck sounds a lot better with the 64mm charger on it now. haha

Smarty rollin coal. Hmmm, Thats dif. These things are normally pretty clean vs the h&s. Maybe he needs an intake to get more air in. That might help a little. But you said he has a bigger turbo so I am sure its not getting starved anymore.

[CumminsDriver635]

It was really clean until he put the injectors in it, and then it would smoke like it does here. With the new turbo it clears up to just a haze once its spooled though.

@shotgoos How is your tranny doing? Just wondering because I have the 6 speed auto too and im just curious of how far i can push it without blowing the tranny
