Lightweight pulleys: reliability & smoothness - Toyota Yaris Forums

mitch9521 · 03-14-2023, 08:26 AM

I have the NST crank pulley on my 2014 and it makes the engine more responsive yes, but you lose rotating inertia which can make it annoying to drive in traffic if you have a manual.

Especially so with the annoyingly touchy but somehow not touchy E-throttle mapping the Yaris has. I'm actually considering going back to the stock pulley to regain some of that inertia back and make it easier to be smooth when taking off but I threw out my stock pulley like an idiot so now I have to go pillage one from the junkyard

Maybe go with something that's not super light, something that just bring it half the weight maybe?
