have any of you guys and girls ever fitted an underdrive pulley kit and then wished you hadnt ??......i am thinking about it but am worried if i will loose out any drivability by doing this ..any advice kindly taken

Many have lightened underdrive crank pulleys or full kits fitted. Supposed to give around 10bhp increase and quicker revving. Its not a massive change though. It wont affect driveablity in anyway, although you may notice more/harsher engine noise with the lighter pulleys.

 

Be sure to buy a properly balanced Pulley set, rather than the unknown ebay variety. Smithy sells the SGP set. http://www.smithys-place.co.uk/300zx_sgp_racing_underdrive_pulley.htm

 

A more effective alternative IMO is a lightened flywheel.
