i a friend has a a civic hatch with a B7 and wants to get a underdrive pulley for a/c and alternator. hes running alike a amp with a 30Amp fuse, single sub, etc. will it affect much or mess up the alternator?

 

oh yea his crank pulley is rusted like ****, so a stock pulley costs him like 30 bucks, a aftermarket one is 40.. so 10 bucks for a tad bit of performance..

just any response will be good, and response from people who have underdrive pulleys will be even better! thanks a bunch

 

All those pullys really do is look nice, not a lot else. Just my opinion tho,

sorry to bring this back from the dead. But ive seen a stock B16 gain 1.8whp from a N1 Crank pulley alone.

Added that just incase some1 is searchin like I am. Gives them something to look at

 

if you wanna do it right balance the cranck with the light pulley.... i'v heard some ugly stories...

you'll get more gains from just cutting your electronics. about every 50amps you save will equal one horse sparred. 62 amps @12 volts is equal to one horse power, so 50amps cause alternators are not 100% efficient.

with the N1? O i know, I was stating it has made a 1.8whp gain on a stock B16.

Ive personaly shatterd 2 oil pumps on my old setup usin the N1 w/ boost.

Boosted honda's w/ any aftermarket crank pulley will end in bad results if you dont have the harmonic balancer. I have a factory crank pulley on my motor.
