If Harrop can make the product 'flexible' I'd more inclined to buy it.
Until now the focus has been getting the SC calibration to market. I've seen and heard the system to quieten down the whine and it's extremely effective but has not been as much of a priority as the calibration. Like everything there will be extensive testing of this adaptation before release to market.

The stock air box which is used is very open and reflects the noise from the Supercharger straight back through the air filter and out the lower duct which is why the whine is so pronounced under load.

I don't get the complaining about the whine...I loved the sound of Mustang Cobras with the Eatons and that whine, and now the S65 with the Harrops...sounds like a win for me.

It's good to have a choice though
