Front mount on ST205 difference? Options

[jbod]

I am shortly about to do a front mount intercooler on my st205.

What I want to know is, has anyone dont this first hand, on a standard 205, and gained a noticeable difference?
Most people that i know that have done this have gone forged and a big ol turbo at the same time making their input in valuable

Please, dont tell me about my friends done it and he says its great or whatever. I want to truly gauge did it make a difference

My issue with the water to air is on the track the water to air gets hot (intake temp in high 50s) and you feel a loss in power.

If theres no real gain felt I will bore my ct20 out to take a 52mm compressor and give it some chilli sauce - and in the process have to retune the ecu. making the front mount worth while

One of my friends has done that has the exchanger from a porsche. Is huge adds another 4l.. However it has the same issue of heat soak, it just lasts longer before the power drops off
