He said they were custom chargers.. Now you may could do a custom 3794 or 4094 or something for the high pressure but not sure if you could with the stocker.
NO... The kit is built on a T4 foot for the high pressure turbo. We aren't going to engineer a kit to be nice and compact, then muddy the water with a dumb VNT, VVT, VGT... VGT Tech is for emissions, not HP.
This is the middle ground, proof a theory prototype. We will do a smaller towing oriented kit, and a larger max effort kit. Just going to take some time. With a set of properly sized fixed geometry turbos, you'll forget all about a Variable setup.
Don't fixate on the heat either, the stinking truck rips! Its no different than a single S366/73 in initial response, just with a lot more pull in the middle and upper RPM's.
