Lightweight crank pulley

[al_v]

Were can I get a lightweight crank pulley for my RB25DET ?????I did a search in google and nico forums , but nothing....

ive never understood the purpose of a lightweight crank pulley. once you total in your entire rotating assembly (pistons, rods, crank, flywheel, clutch, transmission, driveshaft, rear end, axles, wheels, tires) you realize you are only shaving a fraction of a precent off. sure it may free rev faster but no actual horsepower benefit.

a underdrive pulley or damper does have a purpose, but not a "light weight" one.

just my opinion.

It's been discussed here on NICO RB forum, search for "ATI Damper"... Here's some more info in a discussion over on HybridZ.org:http://forums.hybridz.org/showthread.php?t=99884

Check under Dyno's upper right hand corner (i believe)300zx

The Rb pulley's are similar in weight to the VGThe RB20 pulley is i think 8-9 lbs
