I know from looking at it it would be pretty close, the filter may do it in but as the owner of a car coming to the end of mods before itb's or sc I always wonder when something like this comes up for sale.

I've had a search but can't find any reference to anyone trying it with or without success.
P.s. I know I'm wasting power running aircon, but the car is a daily in Australia so it's nessecary.
Cheers
Bill
