I used a small digital display from Maplin that allows up to four remote temp sensors to be connected (it also doubles as a clock!). I've put one temp probe right at the front of the chassis, shielded as much as possible from the cooling effect of high speed, and one in the airbox via a grommet in an unused hole in the backplate. The display unit is rigged with a small switch so I can switch the display between the two sensors and see the relative readings for external and inlet temperature. Cost of the whole set up - an amazing £16 plus battery, cable ties and a piece of ali to mount the display (p 645 of last years Maplin Catalogue part nos FE33L and 2x FE34M). I can send photos etc if you let me have an e-mail address.
