How much INSTANT HP is a Front Mount Intercooler worth?
 

Keeping everything the same and not turning up the BOOST even more, how much HP can I expect from slapping on a decent size FRONT MOUNT intercooler?

depends on which FMIC etc etc.

just guessing i would say between 35-45hp, but not sure

haha, not that much. your lag will increase a little bit too.

density change = (orignal absolute temperature/final absolute temperature) -1

intercooler drag
power loss = 1 - (14.7 - psi before intercooler / 14.7 - psi after intercooler)

Ta = temp of ambient air going into turbo
Tco = temp of air coming out of compressor
Tio = temp of air coming out of intercooler
Intercooler Efficiency = Ei
Temprise = Tco - Ta
Temp removed = Tco - Tio
Ei = (Tco - Tio) / (Tco - Ta)
YAY!@!@$

that's an impossible question to answer, there's too many variables. you could even lose power (not likely, but it's possible)

at a guess, i'd say you'd get a more accurate answer asking how long a piece of string is.........

twice the distance from the center to either end of course!

In Particular i would like to know what type of gains are normaly achieved with a front mount I/C from a starion or similar set up. I can't imaigne it being worse than the stock set up. The only thing left stock on my car is the motor, I/C and Turbo.
