underdrive pulley

which underdrive pulley is the best? i was looking on ebay and there is a civic type r pully for $65 and its only 1.8 lbs.

not worth it

none of them are worth it

underdrive pulleys suck ass

they dont give shit for power gains

they harm the accesories that you underdrive (alternator etc)

they do not have harmonic dampeners in them so they put added vibrational stress on the engine causing it to basicly shake itself to death

more power can be gained for free by simply removing the power steering and AC

 

[erebunicrx]

even a factory civic type r one?

doesnt have a harmonic dampener

will result in higher vibration in the engine

and its not a stock part

its the part they use for N1 racing

those engines only have to last as long as the race is

so for them HP is more important than lifespan
