▀▄ eas | Macht Schnell - e9x M3 S65 Performance Underdrive Pulleys

Pulleys in stock!! Call today to get yours today!!

These seem like a great gain for the price. My question is whether they will have any effect on the operating temperature of the accessories that they underdrive? I am concerned that the power steering pump already gets hot at the tack and I don't want to make that worse.

HUGE thanks to the guys at EAS today. I LOVE my pulley! You guys should post up my EPIC HP gain from the pulley!


As a mini review, I IMMEDIATLY felt a difference on the way home today.

1.) acceloration is MUCH faster. My car screams! I can honestly feel it. I love it!!!
2.) DCT downshifts dont jerk me forward as much as they did before. It seems smoother to get the RPMs up without my engine braking me forward right after I downshift.
3.) Maybe its me, but I swear what little highway drone I had prior to this mod is MUCH less than what it was before.

Im very pleased with this purchase! Best bang for the buck mod ever! Thank you to all the guys at EAS. You are all great!

You guys should post up my world record HP gain dyno print out! Unless Im reading it wrong, I saw a 16.99HP INCREASE!

So tempting.....

DO IT. First two runs were megan exhaust and drop in filter. The last two were after the MS pulley was added. Im not BS... I honestly FELT a HUGE difference.

Haha definitely a world record. Congrats! Need a lesson on where the hp comes from on the pulley, other than lower rotational mass?

I think it "parasitic drag" that it minimizes.

Hm ok, have to look into it more. Or maybe I'll just stop by EAS and pick Tom's brain.

Cars and Coffee tomorrow in Irvine. Go go go!

Correct. Pulleys "free up" power instead of making power.
