The 185mm will provide you the most boost at every engine RPM level (the 181mm won't be very far behind) for $850 OTD.

A stacked system using 178mm pulley and Code 3 Pulley with a belt wrap kit will set you back $970 + $649 = $1,619 - - plus what ever the belt wrap kit will cost you. Not to mention the headaches of trying to make it all work.

One way to look at it. - once you bolt on a larger crank pulley (any one of them) you will spin the accessories faster - but not overdrive them until you reach:

Stock @ 6000 RPM
178mm @ 5,160 RPM
181mm @ 4,980 RPM
185mm @ 4,860 RPM

With the AC off - the extra parisitic drag is almost non existant - plus flowing your coolant a bit faster could be a good thing.

Just something to consider...performance gains VS risk.....price VS performance....there has to be some trade off....has to be....
