I've not had the car on the rollers for a before and after to establish what the power gain is for the cone, but it did make a big difference! With the standard air-box when you changed gear at say just under 6K RPM, from 2nd into 3rd gear, you'd have a slight delay before the engine hit it's sweet power spot again. With the cone, the sweet spot is much lower down the rev range so when you change out of 2nd and into 3rd you slip straight back into the power band.
I'd guess the increase in torque and BHP is fairly small, maybe 10-15 BHP? But it's much more drivable and you can get through the gears a lot quicker!
The induction noise is good. On tick over when the automatic choke is on you get 60 seconds of high idle and it sounds like it's going to take off. It's also given the engine a bit of an over-run so it pops and burbles through the mid-sport exhaust when you engine brake!
