What would be the best stack for a 6.7 and what would i need to do to get 600+ hp manual transmission

 

It most likely won't happen with a stock charger on #2 only. But the Hot Edge and MP8 would be a good stack right now with a DPF delete and EGR delete.

 

well my roomate has plenty of money to blow and he wants to know what all he can do to achieve it

 

The had one in Diesel Power that made 600 hp. I believe it had FASS, injectors, EGR and DPF delete, SPS62 and EDGE Juice.

 

Do the 6.7s need different turbos then the CR 5.9s? Im thinking about getting one but want to run the twins that Im building on it

 

It is challanging to get to 600hp on #2 only. There have been a few, but it is not as easy as a 5.9. The tranny upgrades are partially here, but there are only torque converters, no valve bodies yet or billet shafts. I here Sun Coast is almost ready to offer a complete 68RE.

Tuning with a PMT, Edge, an MP8, EGR delete and DPF delete is good to 450hp at this stage of the game while keeping EGT's in check. Torque at 450hp would be 1000 ft lbs or more.

I think Industrial injection can do some stuff with the VGT turbo, but that is a weak link. You can also do injectors, but you will have EGT problems easily and I do not know of any CP3 mods yet.

It is too early, but the 6.7 should make good HP with very high torque numbers.

 

You need to try to talk to Raw Diesel. I talked to them at a truck pull about a 6.7 and they have one set up almost like a 5.9. I almost went to watch it pull, but the pull got rained out in Stanford.

 

I keep waiting for the 6.7's to all start get "figured out" and start making big power. It will be interesting I bet.
