The Pro cooler is no good for anything more than 18psi on a standard T3 never mind a GT30!

My friend had an RS1600i with a 1640cc CVH using a T34 and a Pro cooler. the cooler was on it's knees after about 15psi (70 degrees C every time it came on boost). Swapped it for a GRS and the temps never got above 28 degrees C.
