Dose anyone know if the twin pass GRS intercooler will flow 350bhp?

Theoretically (and according to 10 minutes on Google) yes. Probably

There are cars running that and more. Gary at APT will know the answer as he has a very good working relationship with PACE products, who also make some very fine intercoolers.

Well it's either the GRS twin pass or the pace front mount for the escort rs turbo. Will have to do some ringing around I think.
