Well, I decided my next upgrade will be an Unorthodox underdrive pulley and aluminum flywheel. Hopefully I'll get some decent hp gains. Once I do this I will dyno it and post the actual gains. Anyone know a reputable shop in WA state I could get the install done at?

 

Might i ask why an under drive pulley? Do you plan on or have a system installed or like your AC cold? Why not just get a lightened pulley. Just wondering, I wanted a under drive pulley at first till i heard the cons on it, and decided on getting the lighter pulley instaed...

 

I don't know of any good dynos in Washington, my budy and I when we can go down too horsepower freaks in portland. www.horsepowerfreaks.com has directions and contact info. It's a bit of a drive but we make it from Spokane and we think it is well worth it.

 

well, i thought this was a lightened pulley. i am not familiar with the difference between a pulley and underdrive pulley. anyways, hereis theitem, pls let me know ifthis is the wrong one.thx.

I beleive an under drive pulley is lightened and smaller, which makes it spin faster than just a lightened pulley, which is a couple lbs. lighter but still the stock size. The under drive pulley will not alow you to charge your electrical system as good, you wont have real cold AC, and your power steering is diminished because of this. If your going to rip the interior out , have no real electronics, and use it mostly for racing, not daily driving then go for the under drive. If you want a system and cold Ac and no effects on the power steering, then go with just the lightened pulley. Hope this makes sense im no expert just read a lot of the forums on here for info.

 

Horsepower freaks is next door to Torque freaks they have the dyno, they are having a dyno event on the 25 of March I believe.

Yep Exactly right. Stay away from underdrive pulley for street duty.

Also, while having the lightweight flywheel installed, also upgrade to a stronger sprung pressure plate. Your clutch disk will thank you and it will make the clutch disk last longer too.

 

I agree put a stronger clutch in while your putting the flywheel on, you might as well since you'll already have the drivetrain apart
