Mm, temperatures will increase but the engines run cool under normal conditions anyway. The best underbonnet insulation I've seen is the stuff they sell for landrovers.. some kind of sandwich of fibreglass and lead, I think. Very heavy, but works wonders... Other than that, I'd just recommend carpet on areas like under the bonnet, it does a fairly good job.
