Dual fuel pumps and twin turbo on a Duramax properly built and tuned will easily push 900hp on fuel only, just like any of the big three's current diesel engines will...stock engine internals might limit that figure to 600hp. 600hp for that setup is definitely a conservative number.

 

he is also using the stock turbo too, it does limit the full potential of the second turbo that is put on there too, and its probably a stock bottom end like k50 said

im sure that mid 600hp also has very low egts: one being that it more than enough air to support that power, and two the dual fuelers help it maintain its rail pressure to a very high level helping to keep the egts down too.

 

The link didn't work for me.

 

The truck was tuned with a mild tune. The dual cp3's are only really for looks he is in the process of a new build should be capable of well over 750+.

 

id like to see that

 

We will have pictures once the truck goes under the knife.
