I have no idea how much power it will gain. More important than a few hp is the increased engine response IMHO

I know that everyone on the forums loves pulleys and such but i had a concern. Won't lightening the pulley totally throw off the balance of the car as nissan had engineered it. If you think about it, their could be a much higher negative effect than positive. This is just an idea and i have been waiting for someone to bring it up cause it does stike me as important. What do you guys think?

Basically someone with extreme knowledge about our car(Sam @ GTM) heavily addvised me against purchasing a pulley. He told me that he has had people askign for them and even though he has them on the shlef he always talks them out of buying it and losing a sale because of the negative effects it has. If someone would chime in and clarify it would be greatly appreciated.

I know of 2 reasons, 1, they'll void your warranty.
2. On some pullies there is a built in harmonic balancer. This is a well balanced mass with some insulation, that keeps the crankshaft stable from harmful vibration by absorbing it. If you're removing this type of crank pulley, you're going to see a shorter engine life. The vibrations damage the crankshaft and eventually your crankshaft will get cracked. These vibrations put a great deal of stress on your bottom end.
