BrownBoy Posted December 8, 2004 Share Posted December 8, 2004 Is a lightened crank pulley worth the money in terms of any performance gains? I see that Perrin has one, and it would fit the 2.5i; from the bit of reading I've done, and experience I've had w/ friend's Hondas, they are somewhat worth it. I would like to get everyone's comments, feedback, experiences, etc. Thanks in advance... Link to comment Share on other sites More sharing options...
champagne 2.5i Posted December 8, 2004 Share Posted December 8, 2004 I think it would be worth it. It is very good place to take rotational mass off the engine. Considering the boxer engine is balanced on it's own and doesn't need a harmonic balancer, it's lighter than most engines it's size. But, going even lighter can't be bad. The great thing about the pulley from Perrin is that it isn't underdriven, so drivability should remain the same, with a little less drag for the engine as a whole. I'm probably going to do it as soon as I see what else is out there after the holiday season. Link to comment Share on other sites More sharing options...
JGR Posted December 8, 2004 Share Posted December 8, 2004 I'd like to hear more about the pulley's from others that have had them installed for a while. 1. Does it noticeably improve the throttle response? 2. Does it make it less "driveable" on take off because the clutch releaseis more sensitive? Theoretically the lighter pulley/less rotating mass is similar to a lightened flywheel. Of course we're not removing as much weight but I'm curious if it requires clutch control when coming from a stop. Link to comment Share on other sites More sharing options...
powbmps Posted December 8, 2004 Share Posted December 8, 2004 I'm curious as well. For the price, it seems like a worthwhile mod. Chris S. Link to comment Share on other sites More sharing options...
LandShark Posted December 8, 2004 Share Posted December 8, 2004 Take it from an LGT 5MT driver with a ltwt crank pulley installed.....it's definately worth it! Seems to free up the revving a lot. Won't solve the "slow roll hesitation" problem except for the fact that it's harder to do. Meaning the engine more easily revs past the bog zone. As far as vibration, noise, etc.....nothing negative to report. From what I understand, you don't want to buy an "underdriven" pulley. I don't think the Perrin one is. Mine was installed by my local Subie dealer believe it or not. I don't recall the brand but it weighed 1.2 lbs. A simple, inexpensive way to get a quick thrill. Maybe no more "real" horsepower but it does seem to send a bit more through the drivetrain. Enjoy! Link to comment Share on other sites More sharing options...
Xenonk Posted December 9, 2004 Share Posted December 9, 2004 It's not an underdriven pulley from Perrin, so it should be fine, they managed to save weight in the process (that's the benefit factor). I do know that M3s with lighten pulley are definitely worth the mod.. so if you want it, go for it, no harm (other than your wallet).

red beast Posted December 9, 2004 Share Posted December 9, 2004 wonder if it would fit on my h6? Link to comment Share on other sites More sharing options...
Xenonk Posted December 9, 2004 Share Posted December 9, 2004 that is a good question, but I am sure it will work since you are still idling the same rpms as a 2.5 engine correct? Keefe Keefe Link to comment Share on other sites More sharing options...
BrownBoy Posted December 9, 2004 Author Share Posted December 9, 2004 I think ima go ahead and get this after Christmas....I want to see if there are any new ones coming out for the new year...def. dont want an underdriven one, so i dont think ill have TOO many options..we'll see tho...i've decided that im gonna go ahead and get one in a month or so...of course, after i've driven around for a while, i'll let you know how it affects my performance...thnks for the feedback guys...

champagne 2.5i Posted December 9, 2004 Share Posted December 9, 2004 More stuff should be coming out in 2005, so no need to rush on the first part you see. Perrin does make great stuff though. Link to comment Share on other sites More sharing options...

Flanders Posted December 9, 2004 Share Posted December 9, 2004 Don't plan on finding one any lighter than the Perrin. I don't think anything will change, just spend your time looking for the lowest price. Link to comment Share on other sites More sharing options...

SUBE555 Posted December 10, 2004 Share Posted December 10, 2004 Seems like mfgs are heading back away from underdrive pulleys. It was stock size, then underdrive, now back to stock lightened units. Cobb is supposed to have a new unit out sometime in the next few months too. Never know, I might do one too and I always said I wouldn't upgrade the pulley. :p Link to comment Share on other sites More sharing options...
RobY Posted December 10, 2004 Share Posted December 10, 2004 I also bought an AP crank pulley... I hate waiting for eons for the engine to rev match my downshifts. Ill install it when it isnt so cold out. If anybody is looking for somthing thats not quite as light, cheaper, or if you feel that the revs fall too fast, try picking up a stock WRX pulley which is a few pounds lighter I think about 5 pounds compared to 9.

powbmps Posted December 10, 2004 Share Posted December 10, 2004 That's an interesting idea. I'd imagine you could find one cheap and it probably looks stock as well. Chris S. Link to comment Share on other sites More sharing options...
