Yeah unfortunately a manifold will have to wait, a spec r cooler was always the long term plan - but the AirTec one came up for £100 2nd hand un-used and is a nice upgrade from the 50mm pace one that I had before
honestly 470bhp will be plenty if that’s what it makes anyway, it had a t3 running about 12psi previously lol
