GarageLine Prototype Pulley Review
 

So I got chosen to test and give a review on the new GarageLine prototype pulley kit. The kit consists of a crank and alternator pulley, stock size, just light weight and made out of 6061 aluminum. They are anodized black for corrosion protection. I am not sure on how much they weigh exactly, I will let Jermaine from GarageLine chime in and give full details on the product, price, etc. The crank pulley does seem pretty light though! I will be installing these tomorrow and will give driving impressions as soon as I get the car back. I am familiar with light weight pulleys and I'm expecting nice solid gains from these, along with the car being able to rev up quicker. My car is a 6MT also. Here are some teaser pictures from when I first got them. I will continue my review tomorrow on how well the car drives.

The pulleys were packaged very nicely. The black anodizing looks great, and the pulleys had no damages, scratches, marks, anything.

If the crank pulley is stock size, what is the need for an alternator pulley?

I believe that the alternator pulley is also light weight. It's not going to shave a lot of weight because its so small, but anything helps

Sweet Keep me posted.

Hey, I PM'd you a while back... What happened?

I replied back???

The pulleys will be finished up tomorrow! Unfortunately my stock crank bolt will not come off without removing the radiator and fan assembly. Stupid bolts :mad:
We are working on pulling that stuff off so that I can get the car back around noon tomorrow. I really wanted the car back today to test my new found power :stirthepot: but it looks like tomorrow will be the day. Stay tuned!

Ok, that sucks.

Highly suggest you do some research on the crank pulley before installing...

No reply ;-(

I'll resend the message! Thanks again guys!

Are these strong enough to work with superchargers? Had to remove my NST's and I loved them.

It's not worth the risk, or the gains. THAT's why they have you take it off

It is underdriven and underdrives the SC. Adding a supercharger helps absorb resonant frequencies. I'm just wondering if it was designed strong enough to support the additional torque from the SC's. Watching a couple sub par pulleys fail (spokes failed), I would def side with the conservative route. This is def a hot topic with divided sides.

I personally wouldn't install a different pulley on a SC car. A lighter crank pulley when you have an additional item 1 or 2 being driven by the crank pulley doesn't really make sense. If underdriven it will make supercharger spin slower making less power and if same as stock diameter you probably won't notice it at all.

Exactly what I was saying. The risk isn't worth the gain.
And while lets say T-6061 aluminum ("aircraft grade aluminum" usually used in these sort of parts) is strong, it ain't that strong. Machined aluminum won't be half as strong as if it was forged.

I was specifically looking for a stock size crank pulley. I know why the stock crank pulley was put back on, I sent it to them. With 6061-T6 having an MPA of 300+ and cast iron at 400, I understand a quality lightweight pulley will not be as strong as a factory cast iron piece. I've done more research than most, believe me. I was inquiring about the pulley design, I'm aware of all the opinions about this mod, with and without superchargers.

So the pulleys were finished up today! I didn't get to take any pictures because I was in class while everything was taken apart. I wanted to install these by myself so that I could see first hand how well they fit, but I just didn't have a breaker bar big enough to tackle this job. My mechanic did a great job. These installed with no trouble at all. I got to drive the car home, and ill do a little more driving in about an hour. My first impressions were that the car does rev up a bit quicker than normal. I put the car in neutral and did a couple light throttle touches to about 4-5k and you can definately tell pulleys were installed. I also did some WOT pulls and I'm very impressed at how well the car revs up even though these are only light weight, stock size pulleys, compared to under driven pulleys. I have had experience with under drive pulleys on my last Z and if I didn't know better, I would think that a set of under driven pulleys were installed. It's that great! I'm thoroughly impressed with this pulley set. There is zero vibrations, noises, anything. They bolted right on as my mechanic said with no troubles at all. I know the stock crank pulley is quite heavy, and I didn't have a scale to measure the GarageLine crank pulley, so maybe GarageLine can come back in and give full specs about their pulley, including price, weight, availability etc. like I said I will be doing some more driving to "break these in" and see if any problems occur, which I doubt they will. I will update this thread periodically to let everyone know how they are doing. Bump for a quality part!!! Thank you GarageLine for adding to the aftermarket support for these cars!!!

;-( don't get butthurt at me! It hurts my ears!!! Lol

haha, I'm not butt hurt, just a bit of debate and showing my understanding :tiphat:

Awesome Review Nitrous, those were my exact thoughts on my own, CG's! Now go out and :driving:

Update! Still no problems! They still feel great and have no noises or any signs of problems! I also love that the pulleys are black. If someone were to pop your hood, they couldn't even tell you had a set installed. They look just like stock :)

Awesome thanks for helping out and reviewing our product.

No thank you Jermaine for letting me test your pulley kit! Oh btw these DID NOT have to be grinded down like some of the NST pulley kits. They just slipped right on. Another pro vs other kits.
When are these going to be produced Jermaine? How much are they going to be also?

I wonder if there is any initial tq lost due to having a lighter pulley wheel. While lightweight does allow for better performance, having a heavier pully allows for more tq.

I understand what your saying. Like you said, it allows for better performance. Off the line, it accelerates quicker because of the loss of weight off the crank. That would negate in any "feel" of lose of torque right there in my opinion. Same thing goes for a light weight flywheel too. But everyone benefits from shaving weight and seeing a positive increase in revs, mpg increase, and drive ability

heavier flywheels and pulleys only maintain momentum off throttle, it also makes clutch engagement smoother. If weight of rotational objects somehow improved torque, everyone would be rolling on cast iron wheels.

thanks for the correction, my boss and I were discussing this and I decided to post this on his behalf without considering the full picture. Much obliged.

NP, cheers

Yeah thanks fire hawk :)

Hi Guys,

I am in Orlando after a tuning weekend, so sorry for the late response. We should have these in 20 days or so. Just need to fit them into the production schedule.

Jermaine

Checking in... Everything still good?

Yes sir! Everything is perfect to say the least. Car pulls great and has no squeaks, weird noises, etc. Any update on the release of your kit? Prices?

We should have these 1st week of Jan. I'm thinking a introductory price of $150 for the pair.

I'm down.

Wow that's a hell of a lot cheaper than other pulley kits. Sweet deal! Even though this is the last thing people look for in a pulley, one of my absolute favorite things about this pulley kit is that they are anodized black. I LOVE the stock look. It's so stealthy. Those small little things really count in my book. Great pulley kit!!

I like the $. I think this is reasonable for pulleys. Looking foward to them. :tup:

Yeah it is. Considering other pulley kits are about $100 more.

Did you mean January or June? I'd be down for a set asap.

I think it might be January. I'm sure they have to make all the sets before they even think about posting them up. Plus they have to run their business and make all their other parts.

Jermaine, would it be $150 plus shipping? I'm just asking because I'm sure others are curious as to what the said and done price would be.

Auto correct from the phone is not my friend.

So we should have these in First week of June or next week.

Maybe I will do a pre-order with free shipping Starting today until next Wednesday.
