What is best crank pulley?
 

I hear a lot about the Perrin and its seems very reasonably priced. Others are appearing on the market and it is confusing as to which is best. I guess my question is which is the lightest and most importantly which is best construction? Can those with experience with various pulleys on THEIR car please chime in. Thanks.

They are all the same basically, just pick someone who makes the color you want. I like these personally http://www.ft86club.com/forums/showthread.php?p=1144930.

I would steer clear of the kartboy because of the increased noise they cause.

Best of luck finding people who have had more than one aftermarket pulley on their car.

Answer: Choose the lightest weight and stick with it like glue and make your choice and dont look back

Also let me ask this for any of you with a pulley installed: which ones produce a whining noise?

I love my Perrin. Looks great, no whine, easy install, and lightweight. Couldn't ask for more, just more Perrin pulleys for the other parts!

I'm very pleased with my Raceseng pulley.

I also left a short review on their product page.

This is the best advice! Here's the pulley weight post.

My Perrin pulley has been on my car for about 10-11 months with no problem. I love it.

I cannot tell because I installed my Raceseng pulleys after the ForcedFab stiffy mount which produces a very whiney supercharge-like sound. I think its normal for it to do that as long as you had it installed/torqued correctly.

Apologies for going a little off topic here, but can anyone tell me if their stock crank pulley had a small amount of oil on it when they first took it out?

Love my Perrin pulley, quality part, no issues quicker revs.

The stock one.

Had Perrin, changed to raceseng! the best decision ever!

Seriously? Were you paid to say that?

Not at all buddy! I have their full Revo S2 kit in my car and it makes a huge difference. it goes up to 4000rpm's very quick. needless to say however, that I have 2.75 over pipe and front pipe so they make a difference too.

But no, i have not been paid to do that. I did my research on line on all light weight pulleys and they had one if not the lightest on the market. I give credit where is due.
Nothing wrong with Perrin, but raceseng looks and feels better.

is like you're asking me if i get paid by ferrari to say they make great cars. ;)

So in your case going from a 1.2 lb Perrin pulley to a .8 lb Raceseng pulley was a better decision than going from the 4.9lb stock pulley to the 1.2 lb Perrin pulley? Sorry but that simply does not compute to me although I sense your enthusiasm for the Raceseng pulleys.

No, my question was nothing like that! It was more like asking why you said that going from the 458 to the 458 Challenge was a better decision than going from a Nissan Versa to the 458. :)

so you're saying everybody that changes one product to another and is happy with it, they must be paid by the second producer?

LOL!

You took that verbatim? LOL!!! No, I didn't think I'd actually have to explain this but that was sarcasm.

I didn't mean to upset you but the way you said that the very marginal improvement from a Perrin pulley to a Raceseng pulley was "the best decision ever" was humorous to me. I don't know you, that may well have been your best decision. If so, I am indeed sorry in more ways than one... :)

Nothing at all wrong with Perrins pulley, I had it and decided just to keep everything same and went with Racesengs full kit. Neither pulley made any noise at all, and both show same or similar benifits overall so choosing either is all good. If you want full kit with all pullies not everyone at this time makes that so decide based on if you care to mix match, what you like for looks and what your budget overall is. Only one I have heard that makes noticeable noise was Kartboys one and thats not to say it's a bad pulley just that it makes a noticeable noise that some folks don't care for is all.

As far as comments on oil on bolt etc.. Mine did NOT have oil on it "factory one" and no I did not use oil in installing either the Perrin one or Raceseng one either. The MAIN thing to pay attention to is to keep the O-Ring on front in its channel while installing new one and that you do not force the keyway out of position in any way. To just install the crank pulley itself is a 5 minute job and ensure to torque proper value as well of course.

The Perrin pulley is heavy as shit.

Haha, no worries mate, i didnt want to sound too abrupt and sorry for that. Yeah, a bit of an exageration but you know what i mean. it was a good improvement over the perrin. I am not saying Perrin was bad, but maybe considering I have purchased the whole set, my opinion might've been biased. So all good,...now let's have a beer.

We made the PERRIN pulley a safe weight knowing that customers will eventually upgrade to a lightweight flywheel. Having been around for a long time with Subarus, we know that lightweight flywheels and light weight flywheels can cause misfire codes.

We of course could have made our pulley lighter, but we just wanted to be sure it'll be safe so customer's don't have problems in the future. We have made a prototype crank pulley that is a little lighter than the production model, we will do some testing on it, and may even change the pulley in the future.

When it comes down to it, being 1.2 lbs from 5 lbs is still going to be huge, and going .4 lbs lighter isn't really going to make much of noticeable difference when our pulley is already 3.7 lbs lighter than the factory part!

I'll drink to that! Sorry for being a pedantic **** about your exaggeration. It happens sometimes when I drink. :happy0180:

More on topic, I'm too cheap to buy a full pulley set since the greatest benefit by far is gained by replacing the crank pulley. I wanted the 1.0 lb Kartboy pulley but not being sure if the whine would bother me I opted for a red Perrin instead. However I will quickly concede that there are lighter and potentially "better" options like Raceseng.

Given some time has passed, just wondering if there have been more experiences or views between Perrin vs. Raceseng vs. Toda pulley kits. I can get the Raceseng and Toda ones for around the same price, but Perrin still much cheaper. Thanks.

Correct me if I'm wrong, but this mod is more for racing and not for daily driving while trying to also stay under warranty, correct?

Trying to stay under warranty.. not so much. Replacing the harmonic dampener with a solid aluminum pulley will most definitely not make dealerships happy.

Can a technically savvy person explain why having light pulleys and flywheel is bad for the engine? What, does it slow down too fast?

I'm not sure I would want this mod for any use case unless the balance has been changed elsewhere to account for it. Generally speaking, messing with intentionally placed mass on parts that rotate in the thousands of rpm's is a bad idea.

You cant lump the flywheel and crank pulley in the same boat. The crank pulley is used (aside from feeding the other pulleys like the alternator and AC compressor) to balance out the engine vibrations. So there is weight, distributed in such a way that the engine will vibrate less, or at least in a more stable way. Making it lighter lets the engine rev faster, but not by a whole lot, and usually has more negatives than it has positives (when you consider the main positive is "it looks pretty cuz its colored" thing.

Lighter flywheel do nothing in regards to vibration, all the flywheel does is smooth out the engine output by storing energy. The engine doesnt produce a stable constant output, its rather in pulses, each explosion in a cylinder is a pulse of energythat goes down your drivetrain. A lighter flywheel will let your engine rev faster as well, but this time with a much more dramatic inpact than the pulley. While you may save 1 or 2 lbs on the crank pulley, you can save over 10lbs on the flywheel. I have a ACT flywheel which is around 11lbs lighter than stock (I think), and the engine does rev up and down much faster than before. It doesnt make the car any quicker, it makes hill starts a bit harder, but it also makes rev-matching a lot easier, which is what I wanted out of it (as well as a few lbs of the car's curb weight). There isnt any real danger that I know of to get a lightweight flywheel for this car (cannot confirm or deny the same for the crank pulley).

This mod is purely for creating endless posts on forums. Do the search.

Best crank pulley is a fluidampr, which is heavier than stock.

My god, thank you.

I was reading page one of this thread and ready to headbutt my monitor.

Fluidampr 100%

Fluid Dampr... done.

Had Perrin, then raceseng..then Fluidampr! So far so good!

Same. Had the Perrin for 500 miles then went Fluidampr. Way better.

I would put back those OEM pulleys if not the Fluidampr

How about 10% underdrive ATI one?

I hear underdrive damages the alternator. Could just be a rumor though.

In what way?

Engine felt smoother. Shifting was different/easier. Oddly enough the car felt more responsive high in the power band.
