After a long weekend of installing a modified CP3, fuel rail pressure relief valve and head studs, our 6.7L is ready to hold some serious power…
Now not only is the tranny no longer a weak link, but neither are the factory head bolts. Our plan is to install a set of twin turbos next. With an AirDog fuel system feeding a modified CP3 from Industrial Injection and 80 hp injector nozzles, the truck is plenty smoky utilizing the stock VNT turbo, so we know we’ve got plenty of fuel to make use of. In fact, with this kind of fuel on tap, we think a rather large set of twins will be in store for a future article. Stay tuned…
