My Whipple is also fairly quiet, but one thing that did help was removing the rubber seal across the top of the Rotofab box. I can hear a little more Whine since doing that. I basically removed the seal because it was causing my hood to not sit flush. So in the process I noticed I can hear a little more whine in the car. I also Haven't noticed any adverse effects in my data logs from not using the seal.
