Engine bay temperatures

I know cool air for induction and intercooling comes from the front of the car. What affect does 'heat soak' have on the supercharger when the car is moving?
A few have cut vents in their bonnet but is there any science behind this? I guess in turbo applications it's more to stop things catching fire?

Wornus - when your running the heat soak is not to much of an issue. Its when you stop the engine that the problems start as the SC is at the highest point and as such gets red hot very quickly then takes an age to cool down.
With cold air being drawn through it you keep it cold when cruising.
As for the vents - I have found they let out an enormous amount of heat and whilst it wont stop the problem of heat soak it does help alot, mine hardly ever get the fan cutting in in the summer TBH and the oil pressure stays nice and high when blasting it and that alone made it worth it for me as I did suffer the oil getting hot on track.

How much do your people charge for putting the louvres in Roger?With cold air being drawn through it you keep it cold when cruising.

^Golly, I take it that's an aluminium plenum as opposes to the stock item?
Louvres will help but to really shift air you could fit 2 fans. They will extract a huge amount of air. They can be linked to a rpm or temp switch. Did it on a TT car with a shoehorned engine so can't see why it wouldn't work on a monaro. The fans are quite light and 8" diameter iirc but size would depend on the monaro bonnet. In fact the fans are probably cheaper then louvres.

Stamping was only about £7/9 per cut I think from memory, I had different size cuts so it varied. Its the paintwork after that hits the pocket!PS - it was the same place that built the silly V6 Pug which was on Top Gear a few years ago when they raced it in a hill climb against a load of old fogeys in an old brit sports car.
It is stock plastic. The Fluke camera worked with its own special s/w which allows you to pick points on the image. The pictures can be exported as jpegs etc.
The inlet which appears orange is approx 45 - 48 deg C.
The feed pipe to the throttle body is approx 30 deg C.
Body behind the engine is 20 and the ambient was about 10. Pictures taken on my drive around 6 pm on 6th Nov last year.
Accuracy is supposed to depend on the emissivity of the surface and ideally should be matt black as the inlet is. The project it was hired for was electronic circuit boards. I sprayed one matt black which actually made little difference, suggesting the readings are accurate and the camera is not fussy on surfaces as long as they are not shiny reflective.
