sashadg1 Posted January 27, 2007 Share Posted January 27, 2007 i couldnt help ya there, im not exactly a fan of underdriven pulleys, not to safe for charging your car, i dont wanna get stuck with a dead/weak battery Do you think UR would make a part that would not give you adequate charging for our cars. They would not be in business putting crap out there like that. The regulator brings the voltage down below 14.5 or so to keep the battery charged even with all accessories on. UR underdrive showed very little to no drop in voltage at all. This means unless you’re running a 500wt stereo system or something you will never know the difference. Just about 3 to 4 HP loss is all you will feel by running a OEM lighten pulley. These are like I said very slight underdrive, just enough to gain around 4 HP while keeping the voltage unchanged. That's a wise tale about not getting enough voltage, at least with this company. I have run Unorthodox UD pulleys for 2 years on another car and never had any issue. Oh one other down side it will take about an extra 45 seconds to feel the full effects of the AC. I also had to buy all new belts, $25.00 or so, no bigge though, almost time to replace anyhow. I will try to do a picture by picture install if I remember. Thanks Scott Link to comment Share on other sites More sharing options...
Guest subiecity Posted January 27, 2007 Share Posted January 27, 2007 oh i kno but in my subie i have alottaa shit running off my accesories , i do have a system with 2 jl 10, amp, and besides running my foglights and demon eyes for me its definitely a risk that i dont want to take, but on my 89 3 series i have underdriven pulleys just cuz i have no ac, no sterio , or backseat for that matter,,,,its strictly my track car Link to comment Share on other sites More sharing options...
reflexion Posted July 7, 2007 Share Posted July 7, 2007 so i had a few questions about the install process.. i saw the video and i have a 5EAT, when the guy puts it in 5th gear well.. thats kind of a problem having an auto i can't quite do that, what do i do instead? and when you're putting the bolt back on the crank pulley how do you know exactly how much lbs -ft or watever you're crankin on? it looks like the guys doing it by hand and just guesstimating.

Mr. Ed Posted July 28, 2007 Share Posted July 28, 2007 ok, to awnser the cobb question about torque.....it comes with no instructions we installed it based off of the write up on page one..... as for the belts...I installed my cobb pulley at 34k miles, we reused the belts. now at 36k miles there is a screeching under heavy acceleration. we are checking the belts today, and possible replacing them. our theory is that it is either the belts or the turbo. it is very consistent at wot in 2nd getting on the freeway etc. so we don't think it is the turbo.

iroczu Posted July 29, 2007 Share Posted July 29, 2007 ok i have the perrin lightened, and being an automatic it took so long since i forgot about taking out the plug on top of the tranny and putting a screw driver or w/e works into the fly wheel so then you can loosen the crank pulley and re-tighten... but as for performance i also have axle back and cai, and i noticed a little better throttle response and afer 4k rpm a little better pick-up. i'm a 03 legacy n/a, with 130,000Km now on it.. but with all this stuff i've put it on about 10,000ish km's Link to comment Share on other sites More sharing options...

qikslvr Posted July 30, 2007 Share Posted July 30, 2007 I installed the Perrin last week and it does make a difference. I can now take off from a dead stop without giving it any gas and just easing the clutch out. It also feels much smoother going from gear to gear. There's no longer a slight hesitation when shifting.

Brad023 Posted November 15, 2007 Share Posted November 15, 2007 i just got the perrin pulley and need an opion on the best way to remove it from an auto any pics of the plug to see the flywheel would help. Link to comment Share on other sites More sharing options...
oliiman Posted November 18, 2007 Share Posted November 18, 2007 hey i have a question! is there anyway for an automatic to tighten the pulley without going into the plug on top of the tranny?? it'd really help:) Link to comment Share on other sites More sharing options...
smack Posted January 5, 2008 Share Posted January 5, 2008 i have the same question as olliiman, how can i install the pulley with a 4eat, i bought it thinking this would be a very simple mod and its been buggin the hell out of me that i cant do it Link to comment Share on other sites More sharing options...
oliiman Posted January 12, 2008 Share Posted January 12, 2008 yea no one ever answered my question soo i jus deccided that the next day when i took my car in for an inspection to ask to have that bolt tightened to the set amount im not sure if whatever mechanic you go to will do it for free but its worth a shot hope i helped out Link to comment Share on other sites More sharing options...
BigT Posted January 14, 2008 Share Posted January 14, 2008 I have a custom tune for stage II. If I put this on will it mess with my tune? Link to comment Share on other sites More sharing options...
smack Posted January 17, 2008 Share Posted January 17, 2008 it really does make a difference on an 2.5i auto, once i hit the pedal the car seems to fly through rpms. and using a screw driver in the access hole(thanks whitetiger) is definately easier than anything else.

qikslvr Posted January 17, 2008 Share Posted January 17, 2008 I have a custom tune for stage II. If I put this on will it mess with my tune? Nope. I will be fine. This part won't mess with any of the programming in your tune. Let's kick this pig! Link to comment Share on other sites More sharing options...
smack Posted February 28, 2008 Share Posted February 28, 2008 i feel like the car isnt accelerating as quick as it was. could this be because the pulley bolt is not torqued to the right ft lbs. should i try loosen it or tighten it. thanks.

nerv_01 Posted March 13, 2008 Share Posted March 13, 2008 Curious about this, there are no degree measurements on the Perrin pulley, has this caused any problems for anyone? I'm looking to install mine shortly, please forgive my noobness if this is an obvious question. Thanks! Link to comment Share on other sites More sharing options...
nerv_01 Posted March 14, 2008 Share Posted March 14, 2008 Nvm, I think i got this sorted out! Edit: FYI for those who are curious, I was thinking along the lines of using a distributor when our motors are obviously electronically controlled.

I'm looking to install mine shortly, please forgive my noobness if this is an obvious question. Thanks! Yeah that's a bad move on Perrin for not doing that. When its time to do timing belt, will need to put the stock back on. Link to comment Share on other sites More sharing options...
