For those of you that have these, what does it do to the power(ex. radio and such)? And since I have an auto do I have to get part number 49-541800, or can I get part number 49-541801(www.thunderracing.com)? Thanks

 

WEllon my 3.4L it woudl dip the ampmeter down to the read at every stoplight but I ws having some charging issues at the time. Either way with jsut the crank one I have a little differnce.

 

I have the crank and alternator pulleys, and I've noticed that, with headlights, radio, and air conditioning on, at a stoplight, it will read as low as 10.5 amps. That's still plenty to power the car.

When the car is moving, it's a non-issue. It's constantly charging.

I've had no problems with them. Just make sure to get a properly sized belt after you get them, or else you will experience belt squeal when you turn on your A/C.
