Re: ’48 GMC Build – Cummins 4BT, 47RH, IFS, 4-Link, Air
hey man
grate work and fabrication on this truck
one question two turbos ok quite normal on modern diesel engines.
I know a big and a smal one to have boost over the hole rpm range.
So you use either the mal one or the big one
But in your configuration they are one after the other, why? And how do they work? Just doubel the boost?
so long
