Just wondering if anybody works for honda. I would like to know if it would be possible to get a bigger pulley for the power steering pump.. Maybe from an accord or prelude/integra ps pump. This would be going on a 93 civic si.

Why do you wanna change the pulley?

A bigger pulley would result in more parisitic losses. If you want better steering try flushing out your PS fluid.

A bigger pulley means less turns. Meaning less work for the engine to turn meaning more power. Also Ive heard with a bigger pulley you steeering becomes stiffer.

if your going to get stiffer steering why not just take the power steering out all together?? then you will for sure gain a tiny bit of power

yeah take it out, and experience what i feel when i drive my civic :P
no power steering!!!

i seen people who's car dont have it.... they seem to require so much effort to turn the wheel.... expesially when parking.... but on the track it would pay off.... big time if you actually have a decent motor

A bigger pulley has more rotational mass which will require more energy to get it spinning and keep it spinning at a constant speed... this energy is being sucked from the motor and creates greater parisitic loss. Same principle is used in race wheels. You ever see 12-second drag cars running 17" wheels? No. Why not? because 13" wheels have much less rotational mass while still being able to support the weight of the car.

regardless, it's your money. But just think, if bigger pulleys result in more power, why don't any aftermarket companies offer them?

Yeah, but once the car is up to speed, you'll get better gas milage. The bigger wheel will cover a greater distance at the same speed.....therefore more Km's per tank. Shitty exceleration though. (but a higher top speed.....it will just take you longer to get to that top speed). LOL

Hmmmmm 20" Dub's.....full tank of gas.......1000+Km's if you do the speed limit.:working:

And potholed rims sooner than you can say "BLING BLING"

I never understood the huge rim thing...

For shows is OK but daily driving , just stupid...

All i know is that the aftermarket pulleys by aem or obx are larger in diameter and lighter. So if you put a larger pulley say from a prelude you should gain something. Even though it wouldn't be lighter. Your pump would spin less making less work or strain on the engine.
