1997 Mazda MX-5 Miata: Screeeal
December 28, 2012
Cold engine, a bit of throttle and a whole lot of belt noise. Project Miata has been relatively trouble-free given its age, hard use and modifications but it (literally) sounds like it's time to check the accessory drive belt tension.
The Kraftwerks supercharger kit uses a Gates belt. It's racy blue and has a heavy dose of Kevlar in its construction. I know these fancy belts make more noise than standard off-the-rack belts, but what I heard that day was clearly a full-on belt squeal a la 1982 Oldsmobile Cutlass Supreme. So, no, there's no "ah, those blue Gates belts all do that" this time around.
