sirbOOm Posted February 10, 2011 Share Posted February 10, 2011 New to the car tuning world. I can tune a Harley, but that's a bit easier. I am seeking a way to get just a tad bit more "oomph" to from the engine pre-2600 RPM (when the, basically, 170 hp 4 cyl. is powering the car). I do not want to make a ton of noise out the back sporting chrome 3" exhaust tips, nor hear the air intake gurgle and 'pssss' every time I hit the gas or shift. Love the Subaru sound (outside of the car), but I have yet to be in a intake/exhaust-modded boxer that doesn't drone like my neighbor's wife . I've come across the Silent-Power exhaust line, listened to it and liked it on YouTube, but it's too expensive... and chrome. (I wish they'd make black mufflers like they do for my bike... that'd be sweet. I don't need chrome pipes under my car... just unnecessary to me... others differ, it's cool.) Anyway... Question is, can I install a Cobb/Perrin/Works crank pulley without tuning the engine or will I need to go in and have the computer fudged with? I'd like to avoid that as (1) it's too expensive for the COBB unit and pro-tune and (2) most certainly voids my ext. warranty which has been good to me so far and I'd like to keep it that way. The crank pulley I can remove (and install the old one) if I ever need to go to the shop for something serious (i.e., when/if my throw out bearing dies). Thanks for the help!

05AWDGT Posted February 10, 2011 Share Posted February 10, 2011 The pulley doesn't change air flow or fueling. It lightens the rotational mass, allowing quicker revs. So no, it doesn't need a tune. Pulley was the 1st thing I did, didn't tune for it either. I think the improvement is more noticed on the 5 speed manuals too. Link to comment Share on other sites More sharing options...

sirbOOm Posted February 10, 2011 Author Share Posted February 10, 2011 Thanks! I was hoping so. I understand it free's up the revs a bit, and that's I think what I'm looking for. For $135 bucks (or a great deal if COBB, Perrin, or Worx wants to give me one), I think it's a good modification. I just wish they didn't come in funny colors.

wpmarky Posted February 10, 2011 Share Posted February 10, 2011 group-s pulleys are black Link to comment Share on other sites More sharing options...
joeblow Posted February 10, 2011 Share Posted February 10, 2011 The perrin one is black too. Cobb is the only one with colors-anodized blue or gold. It's cool; I'm with the band Link to comment Share on other sites More sharing options...
BAC5.2 Posted February 11, 2011 Share Posted February 11, 2011 Eventually, when ever I can trick myself into justifying it, I'll get the Kartboy one.

wizkerbizket Posted February 11, 2011 Share Posted February 11, 2011 Does any body make a red one? BAC5.2- why would you need to "trick" yourself into justifying the kartboy? Its cheaper than the others isnt it? Link to comment Share on other sites More sharing options...
BAC5.2 Posted February 11, 2011 Share Posted February 11, 2011 Because it's a totally unnecessary mod.

ClimberDHexMods Posted February 11, 2011 Share Posted February 11, 2011 It's minimal bang for your buck. As for your aftermarket muffler hunt, you can take any metal tips and sand/prime/paint them black [CENTER][B][I] Front Limited Slip Racing Differentials for the 5EAT now available for $1895 shipped, please inquire for details!

Mark34 Posted February 14, 2011 Share Posted February 14, 2011 I'd stay away from Worx Tuning, if they're even still around. They seemed to make some nice products, my friend has their springs and pulley on his STi, but when you pay and they don't send you anything and then they disappear, it's not that good.
