'03 Z71 Tahoe - ByeBye 11mpg.. Hello 4BTA Cummins
#121
Havnt had time to get the others done yet... but here is a short video showing how boost comes on.
Still needs more fuel... lol
Here are some better shots of the atmosphere turbo...
Might tinker with it more today.. have a new governor spring to install and some tuning on the pump to do... not sure if I'll mess with it or not today.
Anyways..

Sorry guys... spaced it a bit..
HX30W / HX35 Compounds - 4bt Cummins Tahoe - Light Take Off - YouTube
HX30W / HX35 Compounds - 4bt Cummins Tahoe - Short Drive - YouTube
HX30W / HX35 Compounds - From a stop - 4bt Tahoe - YouTube
Still have a lot of tuning to do and I found an exhaust leak I need to fix between the hx30 vband and intermediate pipe that goes to the hx35.
I did install a new gov. spring which now keeps it from defueling before shifts.. need to bump WOT shift points up a few hundred rpms to take full advantage of it though.
More to come over the long weekend

Thanks man.
Did some tuning today on the pump... 40psi feels great! Gonna need head studs before pushing it further... if I even do. It currently pulls great.. sits you back in the seat pretty good and will push this near 7k# suv to over 80 pretty quickly for what it is.
So far... I'm very happy with the outcome.
