Stillen Crankshaft Pulley

I recently had this installed when my car was in for warranty work and they had the drive belt off anyway. So I cannot comment on the exact install, but I would imagine it is fairly straight forward as I have installed pulleys on other cars before.

As I expected, there is not a huge gain in performance. However, there is a nice improvement in throttle response. It revs much quicker now. I always thought this engine was very slow to respond to throttle inputs. That is now much improved.

I would not make this your first mod. But it is a good improvement considering the relatively low cost. Definitely worth doing if you are already replacing the drive belt.

I have the same one. Install wasn't too difficult. I reused the stock oil seal and the original bolt. All worked perfect. Has about 3-4k miles on it so far.

Interesting. I'm wanting to do it just concerned if it will harm reliability or not.

I have had the part installed for over 1 1/2 years and no issues. It is not a part that makes a huge difference though.

Sweet. Just ordered off eBay $115 shipped.

Just looking to drop some rotational mass. Already lost 16lbs on each corner with rpf1 and pilot sport 3+. I noticed a good difference when changed tires, hoping this will aide and help rev faster.

Nice find. It will be a slight difference compared to your wheels and tires. You lost 16lbs. on each corner?!? Did you have solid steel 26" chrome rims with runflats or something?

Yeah that's crazy haha, lightweight forged wheels can be under 20; the stocks depending on what year/size are around 25. Michelin PSS can save a few pounds too. He must have went all out to save 16lbs on each corner, damn

Sorry for delay, just saw your post.

So oem 17 inch rims are 27ish lbs
all seasons I was running 27lbs
= 55 lbs with lug nuts

17 inch Rpf1 are 15ish lbs (12 ish lbs lighter)
Pilot sport 3+ tires 23lbs (4lbs lighter)
Lugs (.5lb lighter each corner)
= 39 ish lbs with lug nuts

Nice work. I lost weight on my wheels/tires as well, but not nearly as much since I went a lot wider on 19" wheels. I wonder how much weight if any I lost on lug nuts. Hmmm... never even thought about that.

How are you liking the Stillen pulley? There are a couple companies that offer different pulley sets like NST but I feel like Stillen might be the better option
