Did some rough calculations and our engines consume air, allowing for volumetric efficiency, at around 380 cubic feet/minute at full chat. That would empty an average double garage of air in less than six minutes!

Blimey ! No wonder mine felt strangled on the original setup, It also runs cooler now

No but I easily beat the guy on the counter terminal trying to find a part number by using one of their snazzy tablets on public side. A real step forward from the books, pens and pads of the past.

Completed airbox mods.

[Linked Image]

Existing 100mm hole fitted with 45° duct fitting and slant cut short section of pipe. Extra outward facing 75mm hole fitted with severely chopped down 90° fitting, both to interface with side louvres to pull in cold air. Total inlet area 123cm3 and greater than OE. In retrospect I could probably have managed with just 100mm hole.

Will be testing tomorrow all being well. Induction noise much reduced is the only observation so far as nothing being pulled from above transmission.

Impressive Richard I look forward to seeing the car tomorrow. Leaving the lower inlet open and adding this air scoop gives a similar open area but of course with the down side of warmer air entry from below. The test drive is tomorrow and I have smoothed of the holes in the box since the photos.
