Temp before IC: ~286ºF
Temp after IC: ~130ºF (usually got 125 to 130 peaks on this run at 15.6 psi boost)
Pressure in plenum: ~15.6 psi (1.1 kg/cm2 on GReddy gauge)
Pressure after turbo: ~17 psi (assumes a 1.4 psi loss in IC system)
IC efficiency: ~75%
Overall pressure ratio: ~ 2.3
Overall density ratio: ~2.2
I really need to do more tests at different ambient tests, at different boost levels, and to place a temp probe from my DMM in the engine bay to monitor air temp near the air filter to get more meaningful results.

Any ballpark figures on the efficiency (or inefficiency) of the stock intercoolers?
