What I get from article
If intake or under hood intake air temperature is 75 º F at atmospheric pressure (14.7psi @ sea level) the turbo outlet temperature will be 285 º F at 20-psi boost. And the IC should drop that to about125f-100f @the valves
90f or higher IAT = loss of power @1%per10°f and fuel efficiency eg:
A 250-HP engine will develop only 240-HP if the air temperature is 130F (54C)
using the same quantity of fuel. Less work more fuel
Cummins retained the 160hp rating on pre91.5 with larger injectors 4x.012" water to air cooler. Vs 91.5-93 got 6x.009" and the air to air intercooler smaller injectors less boost with the same 160hp is a good factory example what happens when you go cold air
1st gen pre 91.5 has the water jacket intercooler that works with newer 12valve and maby 24valve heads. Blockheater is able to heat intake air@ plug in with coolent.
