im thinking of putying 2 little holes in the front of my bonnet to one side at the front. like some of the rally replicas have. is this just a matter of cutting 2 holes then fitting some mesh behind????

You will have to make sure you miss the strengthening struts that go diagonally across the back of the bonnet.

Do remember that you will need to find a Burberry hoody to wear and a lot of items of bling once you have completed this tasteful modification.

;D

lmao :withstupid:

On a serious note though, if you want a bonnet vent, get one near the carb, cold air = more power :) it gets pretty hot down there, I remember reading somewhere that on the bike engined minis, a roof scoop forcing cold air down to the carb or throttle bodies was giving an extra 5bhp or something similar. Not sure if you would see that big a gain on a normal 998 but it must make a difference ? Anyone got dyno tests of something similar ?

Almost making enough extra power to negate the extra drag of the roof scoop there then!

Won't do anything for a mini, once moving above 20mph the carb gets air that is the same temperature as the ambient air temperature outside the car.

I second that lol!


I read on another forum somewhere that some geezer went out for a spin in his mini. He had a temperature sensor mounted at the front grill and one mounted right at the carb to see how big the temperature difference was. He recorded pretty much what Jammy said, when you are moving the air flow around the engine makes the temperature at the carb pretty much the same as ambient at anything over crawling pace. Cold air feeds, bonnet vents all bling, not really necessary unless you've got some hefty mods!

Yes, as long as you can find a hole cutter big enough to fit in a normal drill
Then spot-weld some mesh behind

sorry if it came accross that I was mocking you, that wasn't intended. If you want to do it then go for it. It's your car and if you want to personalise it then do it! :withstupid:
