I'm leaving it.
at high speed the cooling airflow through the bay is fine.
the purpose of raising the bonnet was to allow the built up hot air to escape up when stationary, which it does.
even after removing the rubber strip, the bonnet still has this thick stiffening beam all across it that restricts the opening. plus I got a massive thick induction pipe going up over & down into the TB which further restricts air going over the engine.
