[QUOTE="singlespeed, post: 24632, member: 264"] Appologies for the number dyslexia yesterday, I had quickly measures a 2mm difference with a steel rule and then confused myself with the dimensions. With a dry morning, I have found my verniers and pulled the TB off to measure acurately. The diameter of the plennum inlet is 63.76mm ( measured horizontaly due to access limitations). As Fredi said, the exit side of the TB is 62.0mm, which gives a step up of this ammount>> [img]https://i182.photobucket.com/albums/x124/singlespeed2007/_DSC9188.jpg[/img] So in theory, the incoming air shouldn't see a step when exiting the TB into the plenum chamber, except when the mounting holes are not drilled correctly... Hence why I used the free play on the bolts and lifted my TB. It isn't going to make much difference, however, every little bit will help [img]https://i182.photobucket.com/albums/x124/singlespeed2007/_DSC9191.jpg[/img] Still some work required, probably gluing the inlet pipe into the bottom of the airbox and smooth it out properly, with a rounded lip. Samco hoses ordered with the resonator delete hose for the bottom end of the airbox ;) 4 weeks to wait for them :cry: [/QUOTE]
