have any of you used steeda's under drive pulley system? what pulleys does it inclue? more importantly, does it affect cooling and city driving(battery charge.....dim lights,etc.) who would recommend this for a daily city driver?

thanks for the help

 

what about different belt size?

 

I installed them a month ago. Its the crank pulley and the water pump pulley and uses the factory belt. No accessories are affected so far, it runs like normal including all electrical accessories. Seems like the engine spins up a lot quicker, and I gained about 2mpg.

 

It comes with the main crank pulley and a new, smaller, water pump pulley. Also, a smaller alternator bolt.

Same belt size is used, reuse your old one.

It slows down the system, and some say you might get less A/C when sitting idle, and you might get less cooling when idling, and anyone with a big stereo system or some sort of big electrical drain will want to not sit with the car on but the engine not started.

All in all... You won't notice anything bad unless in an extreme situation... But, you may not notice performance increases either. That also depends on who you talk to.

I personally would never do pulleys because the the big crank pulley is designed to specifically dampen a certain harmonic frequency so the crank doesn't shatter.

Anyways, cool.

 

I have them, and when I first got them I thought I noticed the power steering to be a tad bit heavier. Other than that, I haven't noticed any negative affects. The engine revs quicker and my fuel economy went up a little.

But, as said above, if you have a big stereo system or are stuck in traffic idling alot you may have charging problems.

 

Just had them installed (along with other mods) and I am very happy with them.

 

Put mine on two weeks ago and no ill effects. Engine revs up more freely. IMO, a good mod.

 

I considered them for a while, but it gets really hot here in NC, and I can't spare any AC power. Also, I live close to everything, so my daily driving might not be enough to keep a good charge on the battery with the pulleys. (I've had the car 11 months, and I only have 7,300 miles on it.)

 

Installed them last summer, no ill effects. +1 on the MPGs and engine reving a little faster.

 

When I was doing research before I got mine, I read comments from many people that lived in souther states that reported no problems with the AC after installing them.
