I have seen some large vents that cover the whole scoop area, anyone got any examples of these or know where to get them?

 

Arnt they for the boys running fmic's? I don't think you can use them for tmic

 

On a TMIC a vent is a big no-no.
I have a Aeroworx CF reverse scoop for sale (bonnet it was on had the clearcoat turn yellow, and was of bad fitment, so I trashed it, but removed the vent.
As a stock scoop works on the Aeroworx bonnet, the vent should fit a stock GC8 bonnet (but I would not do it without a FMIC)

 

No worries, will stick with the scoop
