For those of you that have measured the boost drop across the intercooler, what kind of numbers are getting and what kind of intercooler setup do you have (horizontal/vertical flow)?

He ask if it was measured not logged. Logging does require measurement, but measurement doesn't require logging.

Curz, you've actually measured it? You've got an RSI setup so a horizontal flow intercooler correct?

technically, you would need to log it to observe the measurement because the data will fluctuate depending on boost level points observed. at 1 psi, probably no loss.at 20 psi, maybe 2-3 psi loss. you need a log of all the measurements so you could provide an accurate answer. so...back to my statement, no one logs that shit. the manufacturer of the intercooler would be able to give you a measurement at a specific boost pressure, but because that data changes at each boost point, you would have to measure it for yourself on your own setup. generally speaking, air to air ICs lose 1-3 psi at 15 lbs of boost. air to water ICs less than 1 psi at 15 lb of boost. mine is at zero since i use meth injection only! I am currently designing an air to water setup for mine

and i am pretty sure RSI has two different air to air ICs...one was designed for lower than 1000hp, the other was for above 1000hp. Will was going to provide me with the efficiency info but never got back to me on it. I was most concerned with the temp differentials pre and post intercooler at different boost pressures.
