vishnu pulley kit
I was thinking about installing the vishnu pulley kit. I was wondering if anyone has done this to their wrx. I have heard of some negative things along with posative things. Anyone with any knowledge on this subject? The kit replaces the underdrive & the crank pulley. Will this have any negative effect. Upgrades to the car now are utec, helix uppipe txs catless turboback.

also heard that it will affect you're ac when slamming down the gas and having the ac at a high level.
just what i heard though, by a few people.
that wouldn't really upset me much. if thats the only problem.

I have heard of people having problems with the crank position sensor after installing this, or any pulley system on a WRX. This is the reason a lot of well known tuner places do not have a UD pulley kit, such as Cobb. Apparently it does not affect everyone who installs the UD pulleys, but on some it can cause the vehicle not to start I believe. I will try to find the thread I read about it and link it here.

I've had the Vishnu pulley and belt installed since Dec-2002. Compared with stock pulley - no CEL, no noticeable difference with accessories (lights, A/C) at idle, not much if any increase in vibration since it is not a harmonic damper, just a lump of weight like a small flywheel at the crank snout.
For those concerned about increased NVH from the Vishnu pulley, it's nothing compared with going to STi engine and tranny mounts!
As far as seat of the pants power increase from a pulley change alone, I couldn't tell the difference. I think it helps but only incrementally.

Thanks for the info. I really don't car about the a/c to much, I'm just looking for a few more mods at a resonable price. The pulleys and innercooler hoses are most likely the next mods. You got to love the i-club; everyone is allways ready to help!

the Vishnu pulley isn't an underdrive to my knowledge, so you won't have to worry about the accessories. the only thing you'll have to worry about is the lack of a harmonic dampener...which will cause more vibration in the crank..but don't get me wrong..you're not gonna break anything.

The Vishnu pulley is underdriven, just maybe not as much as some of the other pulleys, thereby avoiding such niceties like dimming lights more than normal at idle.

I have heard . . . why do people write this if they don't know? It is just B.S., stick to what you know! Instead of taking up bandwith needlessly, provide this guy good fact based information. Go back and count how many people responded with n00b worthless hear say answers, come on you guys make the list worth while.

I know I have had the Vishnu "underdrive" pulley for 20k miles and everthing is fine. There is no rough idle, my a/c is cold, my engine hasn't blown up, my lights work fine and my 250 watt amp powers my stereo and aliens aren't coming out my exhuast pipe. I can feel the revs climb a little faster. Your experience may vary.
Enjoy!

i have a 1.8l engine in my L coupe and i have the vishnu pulley. and i guess aftermarket ones vibrate more which can damage the seal behind it and can leak oil. i have developed an oil leak RIGHT behind that pulley and im pretty sure thats what it is. ....could be from the pulley or maybe not. who knows.
