Does anyone know the weight difference between stock and SR Motorsports pullies?

 

I wouldn't "upgrade" those pulleys.

Sure you'll gain some horsepower because you won't be losing so much in the drivetrain, but underdriving will have some bad effects if you plan on having a sound system.

Not to mention most pulleys have harmonic balancers on them from the factory, and I'm aware that the Unorthodox Pulleys don't have those. I've seen them rip apart other cars before.

 

Dude You do not know what the hell you are talking about ! I have a Memphis Audio and Audiobahn system which sounds fine. You guys are confused,when I had my Prelude and aftermarket pullies, there was a definite drain on the electrical system to where the lights would dim when at idle and the A/C would noticeablly slow down. Not so with the SR pullies. There is virtually no noticeable loss during idle and have shown to increase at least 8 WHP.
There is also no harmonic balancing issue with these pullies. There seems to be more commentary from people who never make the commitment to add the products they bash !
Sorry for the rant, but if you have something to say, be knowledgeable.

 

The rotary engine isn't balanced/dampened via the front crank pulley. I have had no issues with my SR set, except a slightly higher rpm before the voltage regulator kicks in and a bit of change with the A/C. There is one thing to consider; those who are concerned with matters like comfort and quietness perhaps should leave their RX8's in stock form as it is a quite capable car from the factory.
