1991 Acura NSX: Sounds Great, Too Bad it's Fake

December 01, 2011

So there I was, accelerating with some verve down a freeway onramp; enjoying the snarl of the NSX's engine just over my shoulder. And then there was that wonderful whoosh of a turbo. Wait, what?

The NSX doesn't have a turbo. Man, that intake whine is really loud. Wait, no, that's not it either. The sound isn't localized to the rear, it's emanating from all over. My shoulders dropped once I had a good idea of what that high-pitched note was. I turned off the stereo (yes, playing Phil Collins) and the sound ceased.

As the resident old guy, I ran into this problem in the past. It's electrical interference. Most times purchasing better spark plug wires would cure it. Knowing that the NSX probably doesn't have cheap spark plug wires, I think the culprit might be cheap speaker wires -- perhaps from the bargain-quality stereo "upgrades" that a previous owner made. Magrath also notes that some Hondas would run power wires in the same channels as speaker wires.

It doesn't bother me, though. It sounds great. But knowing it's fake is disappointing. If it were mine, I probably wouldn't bother fixing it. The best soundtrack is still coming from the engine bay.
