The main thing that put me off is the 2 pipes on the left hand side reducing into one, surely that cant flow smoothly through

Dont have any experience in that so i may be completely wrong.
If i had the money i would get my mate graham who owns grs mototrsport, to knock me up a custom intercooler. He is the master of intercoolers lol, he is very big on the ford rs scene ie cosworth and the new mini cooper s, the one for the mini performed much better than the forge one in back to back tests. It is also ranked as the best top mount available for the cooper s.
He can do custom ones and has recently done a custom intercooler for a porsche turbo which is a very nice bit of kit.
If there were loads of us wanting one, i would use mine as the test car and he would get us a few made.
Hes also good friends with ray west (west tuning) very experienced tuner. Ray rates grahams intercoolers very highly

Heres a few of his intercoolers on different cars

. I can ask him if he would do it but would need a few to be interested.
