Vents – adding performance with Bonnet vents.
Performance gains are possible with the addition of bonnet vents.
Warm air really does kill performance. This is due to the air intake temperatures being hot and air at high temperatures carries less oxygen.
When driving an engine hard the under bonnet temperatures quickly build up and the engine has no choice but to suck this air in reducing your power.
Principles of porting an engine and big valve conversions
The inlet and outlet ports on the engine block are usually larger than those of the manifolds that connect to them.
This allows for scope in the manufacturing process to allow for mismatched alignment.
Generally the engine ports are larger in the upstream flow direction avoiding turbulance but power gains can be made by matching these up.
