Do Lightweight Pulleys FREE Power? With Poll

LW pulleys & FW do not add power, but acceleration with them is faster, which is often subjectively associated with having more power. That's about it, don't get why there is any need to do any poll on what share of drivers believes what. It won't change much how many will or won't decide if it's worthy purchase/upgrade.

I don't recall ever seeing any other type of post from them.

Based on physics I'd say they don't increase HP, but might improve net or effective power, if that's the right term). By reducing moving mass in the drive train the engine can respond quicker to throttle input. In the end I believe the net result is same HP at same RPM on a dyno, but possibly a steeper curve on the graph reaching the same peak.

Just read the article. Under drive implies larger diameter pulleys, not necessarily lighter weight ones. As in putting less power to the water pump, alternator, etc in order to have more available to the flywheel. Possibly risky to the performance of the under driven components.

Sorry for adding click bait if this is an advertising ploy.

They reduce "parasitic loss."

The link in the original post includes a good amount of technical info, along with real world dyno testing information, and feedback from real world users. Anyone interested in reading real world info is welcomed to click the link and read, then search the blog for dyno testing with Subarus, Nissans, Toyotas, etc. etc.

Trolling and forum bashing is unnecessary and unproductive.

Thanks all.

Ok, so for our platform, I see a peak increase of less than 5 HP and less than 3 torques. And for a cost between 128 and 486 bucks, which is 168 and 640 canadian.

That's a hard price to swallow for such a small gain, especially when a 50 dollar air filter will give you that gain. Plus, there's no mention of how many dyno runs were made. Did the cars without the pulleys ever put up higher numbers than the cars that do have them? I feel like with such a small gain, there's some fudge factor here.

Not to mention the whole debate of whether or not LWP are possibly damaging to engines. Not trying to light that fire here, but simply because there's no clear cut answer, that's enough to keep me away from them.

Clickbait title. Zero actual content in the post, just a link.

Is this an actual contribution to the forum and/or a discussion?

I'll start a discussion.

What are the merits of the NST Pulley vs something like the Fluidampr?

Merits? Hmm. - Extra bling, ligher weight.
Drawbacks - loss of dampening, which may affect bearings life if used together with lightened flywheel, from what i've heard on this topic, where people advised use LW CP - OR - LW FW, not both.

DAT THROTTLE RESPONSE DOE! !! GAINZ!!!

[empower-auto]

They look good but don't do anything worth mentioning performance wise.

Get a light flywheel.

[why?]

If you think one isn't worth much then the other isn't either.

As someone who has had a 3 piece NST pulley kit, a lightweight flywheel and super light weight wheels on my Yaris for over 5 years, the change is dramatic in how fast the car revs, and because I am a gas mileage freak I get better gas mileage as well.

Now could a boxer be different? Of course, but if the stock engine can take all sorts of forced induction, then a pulley kit is not a big deal. I will say the NST pulleys are much more expensive than what is stock, and that is the main reason they would never do something like that oem.

Shouldn't posts like this be in the commercial classifieds as its obviously a big fat add from our blonde haired friend at NST.
