The 'Pomeroy trophy' Seicento 899cc

20 to 40 mph... roll on test

5 repeats for each
Standard... With brand new paper filter
Then the airbox lid opened and just moved a little to allow a little flow

0.5 second improvement for the free flow

Crude admittedly but interesting ...

Cold air set up it is then... Who's got a cheap one to sell me?
