Why would a diesel truck need it? They may have a fuckton of turbo lag but for their purposes it's not necessary once the turbo has got them going they rarely need to accelerate too much.

Why do you think ball bearing turbochargers came about, ball bearing is useless in drag racing. The ball bearing turbochargers lose less rpm between long/slow shifts as well as boost response (needed in auto-x or road racing) and it does take a second for a big truck to shift. It would also make it easier for hill climbing, you ever seen an 18wheeler go over a mountain, it takes forever and is very dangerous. You shift a gear on an incline like that IF you could even get it out of gear, you are dead unless you bail. Think of the amount of weight they carry, the brakes sure as hell arent going to stop that thing. And if you managed to get it out of gear you sure as hell wont be accelerating back up from a dead stop. It might also be able to assist in down hill descent.
You can learn a lot about 18wheelers from rednecks that go to your local community technical college.
hydrochargers have been looked into as well and its just not practical. It would basically be a supercharger, but with added unneeded parts and fluids. I know some wrecker trucks are twincharged ( blower and turbocharger)
