I have a 50mm Pace Intercooler (500 style). Anyone have experience of what these would be effective upto power wise?

At donington national day on track, found the ACTs rising towards 50 degrees
I'm going to fabricate some deflection shields to ensure air at the bottom of the cooler goes through it rather than round the side and the bottom, which should help.

Car also started to overheat, not sure if this is a result of the high ACTs impacting on engine heat generation, or not great air flow through the cooler/radiator.

I'm running t34 with 2 bar boost, I did notice that on 1.7 bar boost ACTs were about 5degrees lower but still very high.

Anyone else used this cooler ?
Cheers
