After noticing the engine temp rising when sat in traffic i've decided to look at venting the bonnet,i've trawled through all the old links and have 2 questions.Why doesn't anyone vent the side panels[i've seen the pics of side panels opened out 50 mm but can't do that] & why doesn't anyone vent the back of the bonnet top near the bulkhead ,not so good when sat in traffic but surely would help airflow when mobile.
Cheers Keith.

Hellfire have vent to the rear of the bonnet, the vented sides allow for a greater degree of cooling on the move as the air flows around the engine and hot air exits at the rear

I have some adjustable stops on the scuttle and can lift the rear of the bonnet 15mm , makes a big difference and can't be seen unless you look for it.

my bonnet vents



same on the other side

personally i would go for vents in the side rather than lifting the bonnet

if you lift the back of the bonnet and a hose splits, you get a face full of hot water.....

i stuck mine in the side too but my reason was when it rains it limits the amount of water entering the engine bay.
