It does significantly help, as the cooler air is less prone to pre-detonation...but I also agree that intercoolers are not bandaids

Put some sort of EM or a knock reader on your car. I bet when you throw on a TMIC on the knock goes up. I am not certain on why this happens, but it does when you go to say a TMIC to a FMIC. A larger, more efficient intercooler will bring your air closer to ambient in the charge pipes.

might be more dense air causing a leaner condition? I don't know. either way, I will put the I/C on and add some boost. :-D Live life on the edge. YYYYAAAAARRRRRGGGHHHH!!!!!!!!!! :twisted:

indeed. FCD is all you need.
have spencer tell you about the ej22t that Rallyteck..? i think just blew up.
no intercooler and 40psi of boost and the engine finally blew.

personally,im not worried about 14psi :roll:

I know it's details...but I like the details.

It's pre-ignition OR detonation. Pre-ignition is more common to occur after sustained amounts/periods of detonation.
