R50/53 Aftermarket intercooler?

The stock intercooler can do just fine for most "normal" applications. You could probably do just as well with a stock intercooler and meth injection in term of temperature versus a GP intercooler on its own. Heat is the enemy and you want efficiency over size.
I have the GP on mine, but it's pricey as hell now. You can do a bunch of things to add power for $2k.

There's no need to upgrade your I/C with the M45 S/C's boost levels, unless you're thinking of tracking the car.
The real benefits of a better performing I/C are less heat soak and quicker recovery. These two qualities are what will help keep intake temps in check. Which is what makes it a better track modification.
The only way to positively effect intake temps with a physically larger I/C, would be to use something so much larger that it would have to be front mounted, and then you loose boost by having to compensate for the extra volume of air created by the I/C and piping, since the M45 S/C will only create a finite amount of boost. Unlike a turbo system that can compensate for the extra volume of needed air with wastegate or turbo size adjustments.

I've used both the stock and GPIC, and only saw a 5-10° drop in temps under WOT, W/M is actually far better than that.

Well I bought a expensive Airtek 60 mm no where near the price of a GP and haven’t really noticed anything. However it does seem I lost a pound of boost so I’m thinking of switching it back. My mods are 16% sc pulley, 2% ATI crank pulley, 380 cc injectors, Miltek header and full exhaust and a CAI.

what’s the difference between the JCW and regular intercooler? I know the JP is the best but not willing to spend $1900 for a few more hp.

Something to think about.
MOST aftermarket coolers do NOT flow air as smoothly as the OEM design. Despite any temperature differences, look for a cooler that has "flow directors" at the entrance to each tube.
Otherwise, move on to the next candidate.
At least that what I'd do, and have done. So far, the original intercooler is still in its proper location.

GP & JCW intercoolers are NOT the same. . .
The standard R53 intercooler is the same part number as the JCW (non-GP) intercooler. The diverter/covers for these two are functionally the same, just different color.
A decade ago several folks on NAM instrumented these two intercoolers as well as aftermarket units, and the numbers said that the MINI OEM intercoolers recovered much more quickly than the typically heavier aftermarket units. So for track use they are superior to anything other than FMIC. (Results might be different on dragstrip or dyno with the much shorter duration of full-power "pull", and less heat-soak.)
Relatively stock looking engine bay, with GP intercooler & JCW intake.
(There is a GP intercooler currently for sale (not mine), and if you scroll down the listing to post #19, you can see a picture that shows how Behr basically spliced two more rows onto the stock intercooler to create the GP unit, here's a link:

GRS makes a great one as we carry it, the GP version used to be the go to until MINI raised the price sky high.

How much boost are you running? I’m running 16 psi and that’s with a 16% sc pulley and a ATI 2% crank pulley.
