GFB 3-Piece lightweight aluminum pulley kit

[Touge Factory]

As most of people have said, these won't show any type of dyno number gains.
Definitely notice the response gains up top though.

NA motors always provided challenges to extract more power without going too crazy with your budget. I'm pretty sure that anyone that tracks the car could definitely benefit from gained 300-500 RPM quicker revs between shifts.
For the price of an intake on the FR-S, I'd say hands down this is a better mod in my book.

no where in there are "pulleys". yes, they are lightweight, but those few lbs will not make a difference. would i run them? yea sure, the more lightweight parts the better. it has caused the knock sensor to freak out on certain year wrx/sti's, that's a turbo charged motor though. i don't forsee these doing any damage to our motors. lightweight pulleys have been out since the year 2000. in those 13 years, nothing has ever happened to any car running them.

Not to sound condescending, but imagine the crankshaft is a straight line. Now, on one end of the line is the flywheel/trans, ect. well, there is whole other end of that line for mass (which still has to be moved by the same crank) that can be lightened. As for how well they work? I surely have no clue but am willing to try. The moral of this story is "to each their own" and no one is too cool for school.

Anything that drops rotational weight is beneficial for quicker revs and acceleration the more weight you drop... and less driveline weight the engine needs to directly move/spin. You wont notice from a shift "feel" perspective like a MT though since that is all "automated" on the AT cars.

THANK YOU!
