I am currently using MrJosh43's lightweight crank pulley. I don't know if he is still selling them. They were $95 for the pulley. Look up "MrJosh43" and send him an email if you're interested. So far, this is the cheapest lightweight crank pulley out there. There is also the Perrin crank pulley that goes for $130 I think. They're both stock size.

Also www.imprezars.com has a set of N1/Scoobysport Crank/alt/PS lightweight pulleys for $250 for the set.

ditto on the Mrjosh pulley. I have it. If you want one that has something written on it, go ahead and spend 40-50 more dollars.. but if you just want a well built pulley that is just as functional as the rest of em.. get the one from Mrjosh.

i was thinking about getting a nonunderdrive pulley that was just lightweight. however i want to also get a flywheel. i know you the consensus is to not run both so which one would you guys/gals choose? how about the people who run both, how is it holding up?

But they are hella expensive.

N1 makes a 3 pully set that is completely stock size, just lightened.

I have MrJosh's pulley. He gave great customer service and his pulley definitely freed up the advertised 4-8 HP. I definitely recommend it to whoever is interested in a non-underdrive lightened crankshaft pulley.

Here's his website: http://tpi.mrjosh43.com/contact.html

The complete pulley set will free you, at most, an extra 1-2 lbs. The crank pulley is teh one that will give you teh most weight loss (from 5lb. to 1lb.). If you just have to get teh complete set, get teh N1 that Larry Ganz is selling. I have heard very good reviews on that set.

From recent posts, a lightened flywheel is better than a set of lightened pullies. For one, it takes off a lot more rotational weight; and second, you'll have teh benefit of teh vibration dampener if using your stock crank pulley. The flywheel comes from teh factory w/o a dampener, so just having that lightened won't harm a thing. Then again, it will cost you a bit to have it installed by a technician.


ps- why are all my 't h e's changed to teh's?

Lol, I just noticed that, too.

What's this about a Vibration Damper? How would I know if my block was "vibrating"? (no, I'm not speaking in metaphors)

Nah...you need to learn about engine harmonics (and no I dont mean teh exhaust note).

As thecrank spins, it creates a vibration. Our cars are pretty much naturally balanced due to the engine design, but for like a V8, teh vibrations can get very bad. They put a giant rubber dampener (which acts as a gyroscope) on teh crank to slow the vibrations and prevent teh crank form moving around (what tiny tiny bit it can) and destroying the bearings. A lightweight pulley removes that dampening and thus allows teh crank to move that tiny bit...and over time will wear some stuff out a little quicker.

But again, our cars engine design is naturally balanced (or teh vibrations are tiny in comparison to a big V8), so teh need for teh dampener is not really tehir. I dont think iv heard of teh crank bearings or seals being destroyed because of a Lightweight crank. I in fact have one and have no problems (had them on for about 10-12k miles).

edit: I think nick is playing a joke on us Cuz I cant seem to spell T H E either!!!

Dont get underdriven. Search around but someone did a test with the pulleys REMOVED!!! This should have been greater gains that that of just underdriven. The gain was so small they couldnt tell if it was sampling error or not (read 1-2hp).

On the other hand a lighened crank pulley has been proven to allow the engine to spin up faster. Reliability is still a question but most have decided its worth the risk.

I've had my unorthodox underdrive pulley on for about 2 years and 30,000 miles.

It is more of a difference.....especially in the quickness in how the engine revs.

If I had to do it again.....I'd probably just get a lightweight one though.

In my excitement I typed that wrong. I meant to say with the belts removed, not pulleys removed

The MR Josh pulley is a hard deal to pass, around 100 shipped is very good for the gain.

Also you can try the Perrin Crank Pulley. I've had mine with more then 2k miles and no problems so far.

What dampener??? There is none on the stock crank pulley...

ive had an unorthodox underdrive pulley on my car for over 40k miles and I have had NO problems thus far. *knock on wood* .

Yes there is a damper built into the stock pulley.

If you look very closely on the stock pulley you will see that the pulley is infact a two-piece setup, with a rubber piece sandwiched between the two. This combination/setup acts/is the harmonic damper.

WEll, when my motor falls apart, Ill let you know...dont count on it though .


The boxer motor is so balanced that a friend of mine that autoxs was going on 3 our of his 4 cyl, because of a bad plug. He noticed that the car was slower than normal, but he couldnt tell that it wasnt firing b/c it felt SOO smooth.

Think what you want... bmws have harmonic dameners and so do v8s and v6s...along with most ofther types of motors.

Honestly, have you ever heard of an underdrive pulley destroying a subaru motor???
