Super GT Ltd is a company in Hong Kong.

I have not seen any threads so i assume no one has ran one. Anyone feeling adventurous? The pulley costs $136 USD + shpping. I have emailed the company to check stock and shipping costs.

From what I have found the OEM pulley weighs 4lbs. The Super GT pulley weighs approx. 1.7lbs.

Edit:

I finally received my Super GT light weight pulley for my 2013 GE8.

The web site claimed weight is 1.763 lbs
The actual weight is 1.525 lbs
The OEM pulley is 4.018 lbs

The hardest part was the install, the Honda crank pulleys are on tight. I have the crank tool so I was able to muscle it off. Carol at Super GT was great. Emails, pay pal issues (on my end, not SGT) and shipping from Hong Kong; took about two and a half weeks to get. But well worth it. The engine is more responsive, and over all feels good with my other mods. Great quality and machining.

 

I have a set of light weight pulleys... but I have not run them yet. There are a couple threads on here if you dig deep. They only article done forever ago I believe by Honda Tuning showed like, a 1whp increase

 

I went there to buy my JDM door sills. Legit place. No haggling though.

 

Keep in mind with lightweight pulleys, it is important they are balanced and not causing a resonance or a deep vibration above say 2500 rpm

If the vibration from the pulley is bad at or above this midrange rpm, it can <potentially> cause bearing damage.

EDIT I simply through 2500 rpm out there. I think its a fair rpm at which the motor should be very smooth as combustion events are happening fast enough to smooth engine operation


So please listen to your motor after you install! If its gravy. enjoy the extra response and slight mpg gain. Might be able to find a few more miles per tank, but it does add up after a while!

 

100% agreed, this is also one of the reasons I have yet to install mine...

It was discussed that these aftermarket pulleys may not be fully dampened which could cause internal engine damage...

But, since I need every possible rules allotted advantage in my SCCA Solo class I will get around to these eventually. If the L blows, then It's either built motor or K time

 

Honda did not use dampened pulleys until the early 90s.


Could find a friend with a wood lathe, and have him toss it on and see if his lathe vibrates when spinning it.

Most brand name pulleys are balanced within a few grams of perfection.

Also, the higher the rpm the pulley is balanced at, the more accurate it is.


When I had previous engine parts balanced, I requested they be balanced to 12,000 rpm, even though the higehst Ive ever spun my previous D series motors was 9200 rpm

 

Actually, I have a full sized metal working lathe and can't believe I didn't think of this first!

Thanks for the idea! New project for my Sat tech day

 

Guys the pulley on any stock Fit is NOT damped at all from the factory. The Fit is internally balanced and the pulley is not part of the balance package.

It is JUST a pulley not a harmonic balancer like other cars.

Before installation balance a clear glass of water 1/2 full on the engine cover and note the ripples in the water at idle.

Install the new pulley and note the ripples if they are the same amplitude you are in balance.

 

I'm sure the topic that pulleys and flywheels "free up" hp has been beaten to death on this forum. The biggest gain isn't hp, it's faster engine acceleration, to get to the hp faster. Again a topic beaten to death on every forum.

Do you know the link? I would be interested in any good reads. I'd be willing to buy you UD set if you are looking to dump it. Which pulleys did you go with?

 

Thanks for the advice!

 

Reasons for engine failure is do to pulleys and fly wheels being unbalanced or improperly installed, aka "it wobbles". Avoid cheap UD pulleys and flys.

As for the vibration, that interests me. There shouldn't be any difference. But short stroke engines are always buzzy you can't get away from it. So I could see it maybe more predominant.


EDIT 7/22/13:

I admit when I am Wrong. And I am wrong... I removed the OEM pulley from my 2013 Fit GE8 and it IS a harmonic balancer!!! The rubber dampener is there. As for the GDs, that is still up in the air. The part number I was previously looking at was incorrect... Sorry for the bad info.

 

The truth. ^^^^^^^

 

Carol Lam from Super Gt Ltd responded to my email. The pulley shipped from Hong Kong to the USA is $163-176 USD. Depending if it is shipped freight or airmail. 3-8 days freight, 10-14 days airmail.

And they are in stock.

I will post a review when I install it.

 

These types of lightweight crank pulley work fine. There were a bunch installed on GDs when they first came out with no problems. The is a huge thread on them in here somewhere.

 

Thanks. I'll dig deeper.

 

I received the pulley and I updated my original post.

 

What made you think it is a harmonic damper?

Just look at your new pulley in the photo it is a solid pulley not a damper so why would the new one be non-damping and the stock one damping.

It you are thinking the rubber insert is the reason think again it doesn't go through the pulley and the pulley is ONE piece not two as it would be if it was a harmonic balancer.

 

The part number that I came up with before was a solid pulley. I must have looked it up wrong. But the pulley I removed is a two piece with a rubber dampener. Here is a picture; I was able to stick my pick in the rubber dampener.



As for engine damage; I have heard of a couple cases where bearing failure has happened and the pulley was suspect. But the engines were fully built, it's hard to pin it on the light weight pulley when the car is running 13:1 compression, E85, and the rev limiter was raised 1500+ rpms higher.

As a mechanical engineer; Yes, harmonics can cause premature wear. But at 150k-200k miles the car will probably end up being trading in before it's an issue. If it ever is an issue.

 

How about a photo of both sides to show that rubber insert goes all the way through?
