I have read a lot of the other threads on intercoolers and about the Frontera ones that seen to be around at the mo, i can't seem to find a definate capacity figure so i went outside and did a few of my own.
I filled 4 different intercoolers with water to check the capacity ( i hope that's how you do it ) and got the following results...
Standard C20 LET held 1.1 litre
2WD Sierra Cosworth held 2.2 litre
Frontera 2.8 TD held 2.5 litre
Sierra RS500 held 6 litre
I have seen quotes of 6 or 7 litres for a frontera and the Wallace 8litre one looks puny next to a RS500 one, whats going on? Or have i just done my sums wrong
