Re: @nd LET 185mm pulley exploded in traffic at 25MPH
Yes all pulley parts WERE aluminum and overall lighter than the stock steel pulley. I have no idea of the failure cause, there was no issues until I heard this noise while putting along in a line of traffic. I did not even go to auto-crossing this year so no high rpm operation for over 12 months.
I WENT WITH the 65mm pulley after consulting Rob at NEEDSWINGS, and he said that the 65mm pulley had better reliability than the 62mm pulley. It was on the strength of his advise that I decided not to go with the more aggressive pulley. I dont want to limit my driving range away from my house for fear that Ill need to tow it home, reliability is very high on my list of needs.
If you look back over my designs of the: oil separator, pulley saver, the super cooler, the dual cai and crossover manifold products in concert with Rob, concept, more power with no added stress. (Lower temp and pressure on the supercharger for instance).
Yes you should be aware of the car and monitor little issues and noises to be aware of its overall condition.
Enjoy, Woody
