Mark I've long wanted to do the airbox thing but not having any idea what its sposed to look like sort of put me off. Fabricating in alum sheet and epoxy is how I would go and should be easy enough ... if i had some sort of plan. After my exp with the heat shield i am now more interested in what happens in the airflow.. How much space do u have between the bellmouths and the strut tower? I'm hoping the list will provide the finer details..... I'm still digesting Errols setup but i'm not necessarily just looking for more power but i'd like to quieten the cabin noise to an 'unpainful' sort of level too esp at the lower ranges. U got any O2 sensors or anything on urs? PS someone asked me to take a pic of my heat shield but after putting it on and taking it off 435 times whilst fabricating, for some reason I don't really want to take it off again straight away hehe
