I know this doesn't directly address the OPs question, but I find the car much more pleasant to drive with just the honest engine and exhaust noise. It might lower OP's anxiety level at his cruising speeds if the extra - and silly - sucking sound wasn't being piped in.

I have personally flown with one in an RAF2000 gyrocopter and a Zenith 601HD fixed wing. I would not hesitate to do it again.
At the revs you are talking the engine is not even at a good fast walk never mind running hard, compared to these uses of them. |
Wow!

oops, I meant 87 miles then, 140 km/h is the max speed limit.
