If I understand this correctly, there would only be a concern at idle speed because anything above idle, the increase in RPM would easily offset the slower rotation brought about by the change in pulley sizes. Is that right?
0 Problems with mine. Had them installed, about a month later Im stuck in bumper to bumper traffic at the beach on a 85+ degree day for over an hour. Guages never changed anymore than they did stock. I noticed a slight increase of sotp feel above 4000rpms after the install as well. My gears negate most feeling below 3000rpms .
i just put some steeda pulleys on today and drove for about 30 miles. my idle got smoother with them, and when accerlerating and/or reving it feels much, much smoother. no charging issues or lights dimming with ac and headlights on.
i am sure the idle got better, because i used to be able to watch my antenna shake. it hasnt shook all day and the car has never felt better. Also, ive thought pulleys to be a crappy mod, which is why i took so long to do them, so i wasnt expecting any SOTP difference, but damn it feels like it gained some nice tq down low and a couple hp up top. good mod(esp. for what i paid =D)
