Aftermarket pulleys saves gas?

[Spongebob]

Does aftermarket pulleys really save gas or is it false?

[Nismo_Freak]

They can by design.

You might be talking about a .5 - 1 mpg difference.

That's good since i live in cali. Would help with the drive around town.

Yes on pulleys! One of the main reasons I got them. Add a flywheel and you'll be receive noticeable gains. I was getting 25-26cty and 31-32hwy in my NA days.

They're in my top 3 list of mods:1. Turbo Setup2. Flywheel3. Pullies

maxtype240 ur car looks pretty hot. like the rims and body but i think u need a new spoiler and the skirts sanded because it sticks out a little

[Juujai]

your rims look flush as !@#$ though

i thought i read somewhere that having lightweigth pullies and a lightweight flywheel can mess up your crank? like it can shake weird or something. is this true?

something to do w/ nissan engine harmonics being messed up by aftermarket crank pulley

[Spongebob]

So getting it is not good? Pulleys are not good for the engine harmonics?

[navysnail]

technically yes, thats right, although i have yet to hear of someone's engine breaking because of an aftermarket pulley.

It ain't easy pimping pearl white... I'm looking for a Nismo spoiler to replace the OEM.

Anyways, it is true that the harmonic balancing is eliminated w/ a pulley set, but since they are balanced and I only road race/auto-x a handful of times a year, I don't worry about it. There are no horror stories regarding stresses/cracks/dismantling of engines due to pullies....
