Has anyone picked up the Stillen underdrive pulley's and installed them? Any noticeable gains in power or MPG?

ive got em, hard to tell how much i noticed because i got them installed same time as the intake, seems to feel a little quicker though

 

Been contemplating this mod myself. Not sure if it's worth the hassle.

gqblair- does the motor seem to spool up any faster? Would think that shaving some weight off the crank pulley would have a little effect

Then again, I know a little about a lot...

 

did they remove any parts from the car like the harmonic dampers?

also were they a pain to install? if you paid someone how much was the install?

 

definitely spools up faster, they didnt remove the harmonic dampers, and idk ifits a pain i paid my boy to do it who has a shop so it cost me next to nothing but it was so long ago i dont even remember what i paid sorry guys

 

sorry one last question - you noticed any negative issues resulting from having them on? seems like most reviews of lightweight pulleys in general show positive results

 

knock wood no problems to speak of, had them on for over a year now

 

That's good to know, I've read some negatives about underdrive pulleys and electronics issues such as HVAC not working as hard, alternator not charging up as well, or aftermarket subs not having the power they need. I want to try these just not at the expense of electronics

 

Many 6th Gen owners have these pulleys, no one is suffering form negative side effects, the negative effects usually happen to owners of cars with smaller engines do a search on it

 

Ah, good to know. I've looked up a bunch on it and what I read sounded like the underdrive pulleys were risky to electronics but the lightweight pulleys were not. Or more specifically combining a high power audio system with an underdrive pulley wouldn't be the best idea. I'm gonna dig around the 6th gen forums and read about them, thanks man!

 

I'm guessing that pulleys will most likely void warranty depending on how cool I am with my local dealership?
