発進加速性能が特段に向上したのを体感できる。プーリー交換は殆んど自分でやりましたが、二度とやりたくない、笑

Small performance gain, gained a few horsepower, allows the engine to rev slightly quicker. 10/10 would recommend.

五年前に初代BMW MINIクーパーSを中古購入して最初にコレを交換。ダンパーがないからエンジンの負担が大きいとかかかれたりもしますが、全く問題なし。中古購入後すぐだったため+2%ぶんの効果を体感していませんが、エンジン影響は感じません。なお、ベルトは純正より少し長めの方が使いやすいですね。バンドーの6PK1400とか、リーズナブルでおすすめ。

fit perfectly, had to install thread lock on the bolt to keep it from backing out. after 3k miles the crank bolt back out, almost lost the pulley.

After research, I decided to replace my harmonic balancer with this 2% larger lighter weight Alta pulley. It bumps my supercharger pulley from a 15% reduction to the equivalent of 17% reduction pulley, and lightens the spin weight on the crankshaft. Some experts say that it could shorten the life of the engine and the components ran by the serpentine belt. Contradictory to that, I have seen comments where R53s have had this pulley installed for over 200k thousand miles with no problems. So, far I have noticed a significant bump in boost down in lower RPMs. I haven't noticed a substantial loss or gain in fuel mileage. But, I don't treat my Mini like a track car. I get on it sometimes, but rarely run it past 5700 RPMs. Buy some cooler spark plugs, and do your research. I'll update if negative outcome. So far so good!

今まで純正で2回も破損していたので、出力向上と破損の心配が減りました。

1週間ほどで他のところが故障して乗り換えになりました。悪くはないですが2%分の価値は感じる期間はありませんでした
