After hearing some suggestions from Andrew, I experimented a little with the idea behind 'cowl induction'. I didn't do this for the purposes of air induction though, I did it to attempt to lower my supercharger temperature. The one thing that the TRD suffers from is heat soak on the S/C. I was wondering if there was a way I could get some airflow over the S/C body to help cool it down a little as I have found that there is a little more power to be had when this is kept cool. So taking the idea of cowl induction where the high pressure air at the base of the windscreen can then be forced downwards through an inlet underneath/on the bonnet, I drilled a few well positioned holes in the plastic cowl underneath the rear of the bonnet. After some hard driving, I had noticed that this appears to be helping a little in cooling down the S/C. I don't own any thermometers for this purpose, but the fact that I could actually sit my hand on the S/C after some driving around where I previously couldn't definitely shows me that there is a difference. I plan to get a thermometer wired up later so I can see what difference it makes etc. Only thing I've noticed is that even though the total surface area of plastic removed equals about 15-20cm2 or so, the amount of extra noise that can be heard inside the cabin with the windows up is quite significant. The plastic cowl sits about 5cm away from the S/C and with only that small amount of plastic removed, you can now hear the rattling sound of the S/C when the engine is revving. It's funny how such a thin piece of plastic can actually block quite a bit of sound.
