Slight change to the look...

Small point,
the lifting of the bonnet is due to the air flowing over the top surface quicker than it flows underneath,this causes the air pressure to be lower ontop than under which lifts it at speed.This is a fundamental of aerodynamics.
Looks nice Iain.

One of the causes Carl...

Only thing that\'s changed since 170mph+ runs at bruntingthorp is the amount of airflow into the engine bay.  Given that the bonnet was rock steady before I\'d put money on it not being the aero over the bonnet causing lift

On the plus side though the increased airflow means great cooling - rad, I/C and the intake that\'s not getting lots of cold air!  Hopefully the extra vents will allow a little more air out throught he bonnet.

If not I\'ll have to pop over to you to see what else might help.
