Peter & Allison Cotes' rally elan has Louvres inserted - note this isn't a +2 but if you do decide to go this route, then they may have some ideas as to the best way to do it.

What about one or two NACA ducts a la Mk14 Elite?
There must be some glass fibre or plastic bits already out there on the market, cut & patch, so to say.

Look at the size of the air intake. This gives an idea as to size of air exhaust needed.
The usual ways of venting the engine compartment (letting the bonnet raise proud, air exhausts in the fender well, bonnet louvres) are only a partial solution to exhausting the air input with minimal losses. The fact that these measures alleviate most symptoms of over heating indicate the seriousness of the problem - no air flow through the engine compartment.
I thought that a NACA duct was designed to input air with minimal losses, not to exhaust large volumes.
