I am going to put the intercoolers in my car through an Independent test in a special wind tunnel which is also used to test heat exchangers for F1 teams, motorsport teams, the military and so on.

I would love to know what you guys think and if you feel if there should be any changes to the data I have been advised of?

I will also test against the GT2 RS coolers as a point of reference unless you think there is any better.

The points of data below is what I have been advised to go for by the company.

CAC Test Matrix
Charge Air Flows: 0.1, 0.2, 0.3 kg/sec
Charge Air Inlet Pressure: 1.5 bar (g)
Charge Air Trmperature: 150°C
Coolant Air Flow: 3, 6, 10 m/sec (High & lowest flow to be confirmed on day of test)
Air Temperature: 30°C
Points in Matrix: 9


I will also receive a heat rejection chart/graph.

 

The Report is a few pages long with lots of different graphs and data etc but here is an example of the data sheet!
