[s-cars] Lower Turbo Hose

[Steve Powers]

probably no. you're increasing pressure and temperature. whether one
offsets the other in your application is a thermodynamics calculation
involving the gas tables.

I aced thermo in college, but as an electrical engineer nee marketing
puke, I haven't used it since...
