I know alot of you prefer the lower pulley, but I like the idea of being able to change back to the stock ratio in just a few seconds.
With just 1300 miles on her so far, she is now breaking the rear tires loose in 2nd! If I nail it at a stop now, it just goes up in smoke, but from a roll it pulls really freakin' hard! Im pleased with it so far. Think Ill get the lower pulley eventually, but this one has got me grinnin' for now!
How do the rest of ya like your upper's? Any problems? How does it compare to the lower pulley power wise?
For those interested, got my pulley from Mark @ LightningForce.
Super nice guy to deal with and went out of his way to help me!!
You can reach him at his email: UNI4MONEY@aol.com. Im not associated with him in any way, just appreciate his customer service and attention to detail.

 

Go and get the lower pulley now. It is freakn awesome! I can spin the tires from a 10 mph roll on dry asphalt.
OOPs, I forgot to answer your other questions. I felt a bigger difference from the lower pulley than the upper. I haven't had any problems and have had the upper pulley for about 4K miles, lower about 2K.

 

If you don't have a chip, get that first.
