There is something to be said about the psychological aspect of the placebo effect though so if people think it makes the car better then the car is indeed better to them.

I'd have to recheck to make 100 sure (so many things everywhere on that car lol) but I believe all 3. I mean they shave a bit of weight that's all one could objectively say lol (can't speak to the revving as im sc'd)

If you want to drop money on it, then go for it. But it'll be 100% placebo. And, if something does happen to your engine and you're under warranty, good luck getting covered if you have a LWCP

Since Tcoat would be disappointed if I didn't check in,
Some simple facts: 1 - The stock crank pulley IS a torsional damper. It is a textbook example of one and testing by a member on this forum shows that it absorbs engine harmonics better than a billet crank pulley. Whether or not the engineers put it on the engine because the engine NEEDS it or not is up for debate. 2 - The stock pulley cost more to install as OEM than a Billet Al. pulley. 3 - Shedding weight from anywhere else on the car will give the same advantage as shedding the weight from the pulley (as far as a human can FEEL). Removing the weight from the spare tire or taking 1/2 gallon of gas out of the tank will make just as much of a difference. (can you FEEL the difference between 12 and 12-1/2 gallons of gas? No, then you wont feel the difference of your LWCP except in elevated engine NVH) 4 - If you feel the need to shed rotational inertia from the rotating assembly (for whatever reason you feel is beneficial) the pulley makes the LEAST difference of any component. Shedding GRAMS from the drive belt would make as much of a difference. Changing the pressure plate bolts from steel to titanium would make a BIGGER difference) Finally my favorite: 5 - Shedding rotational mass from the rotating assembly will NOT give the engine more horsepower. It is simple physics. 6 - a lightened rotating assembly WILL be noticeable in rev rates when the engine is out of gear. There now - Flame ON! Disclaimer - I AM an engineer, so lets just get that out of the way so that everyone can tell me that I don't know what the fuck I am talking about. Engineers seem to get told that more than anyone else on these forums. If a fireman tells you how to put-out a fire they get thanks. If a member of the armed forces talks about anything, they get a "thank you for your service". If an engineer states that they are an engineer they immediately get shit on even if they are regurgitating facts. |
