I have a modded 500hp plus sapphire and now have a 2wd standard bonnet as opposed to the 4wd vented bonnet I was running previously.
Do I really need bonnet vents to release the extra heat from a big turbo?
Or will the non vented bonnet be fine?
I will heatshield the underside of the bonnet and was even contemplating jacking up and spacing the rear of the bonnet on the hinges (I quite like that look tbh)

Cheers Paul
