GQ UNDERBONNET HEAT

Post by Red Rover »

The TB42 now has extractors & FARK it gets hot. HOT DAMN HOT. I reckon a bonnet vent, but i havn't found any good ones. I thought about a gu scoop but unless i face it towards the windscreen i don't think it would work. any thoughts

Thanks in advance

raise rear bonnet mounts a bit??

Ive seen a few fourbys go around with that with the rear end of the bonnet being raised a bit to allow airflow to escape??

The raised rear bonnet is a little dodgy for my liking. In a front impact instead of the bonnet folding its more likely to shoot back into the windscreen.

A GU bonnet scoop mounted backwards work well and is an easy fit. I know of a couple who have alse fitted fans to pump out air.

Also at higher speeds the back of the bonnet/base of the windscreen becomes a high pressure area and will actually push the air in rather than let it out.

Leave it all alone. The standard exh also gets just as hot. Headers cool quicker.

THe extractors were making the battery so hot it wasn't funny. Last night we oxyed three bolts to the extractors, two on top & one vertically on the side and mounted the original heat sheild. Has reduced the heat from the battery area heaps, but I will still mount the scoop to allow the hot air to escape. Obiviously it is off road crawling around it was at its worst. We came up with the fan idea last night as well, going to look into it - thanks. Good idea about wrapping the hoses up- i'll try that. I reckon it all comes down to the heat shield as the staring point.

Thankz guys

what about the coatings you can get done on extractors/exhaust, i have seen a car after running the 1/4 and the rocker covers were too hot to touch but the coated extractors wern't.
