What do you guys think is a better flywheel for a na? Jun or ClutchMaster? I also heard that the CM flywheel is too light and loses torque, true?

 

Please do a search on this as you are going to miss all the good info on this subject.

If you have a USDM Starter I would not recommend the JUN Wheen because the USDM and JDM Starters are Slightly different and there has been problems in the past with USDM Engine users and JUN FW.
What are you using the car for? Is it a daily driver? Do you frequent Heavy traffic? these are all question you need to ask yourself.
I currently run a Spoon 4.1kg FW which is about 9 pounds. I love it but it is a little tough when driving through Traffic. I personally wouldn't go lighter than 9 but that is up to your preference in driving. Do a search and you will get some good INFO
FYI you don't loose or gain Torque or HP. Light FW is for the purpose of faster Acceleration. The Lighter you go the Faster you can accelerate, but it comes at a cost to driveability There was a poll on this a few months ago and seemed that most people prefered around 12-8 pounds or something like that.

 

Well it is going to be a daily drivin and semi racing. Also the jun is 10 pounds and the CM is 8. I was using the CM fw for a while and it reved out very fast, thats why I was saying if I was losing torque. People at performance shops like Rage and One said that and also alot of other people.

You loose Inertial Mass, so it spins up faster but does not carry as much momentum between shifts. Its great for rev-matching and driving in autoX/roadcourse conditions. For drag you'd probably want something more in the 12lb department.

You will not loose hp/tq to this upgrade, just the feel of it.

 

The lighter the better. I went with the 6.7lb comptech one, and wish it was lighter.

 

i could be wrong but you do loose HP with a heavier FW. you don't loose any at the crank, obviously, but you will at the wheel.

not always the case.

the flywheel with the lowest rotational moment of inertia (that will stay in one piece) is what I would desire.

 

i just put on an ACT flywheel and clutch, it feels like stock.

what he said

 

if it turns up faster.. it will also drop faster too. (than stock)

 

"The lighter the better. I went with the 6.7lb comptech one, and wish it was lighter."

Yup, Have no regrets- go for it.

OH BOY here we go again

Lighter is NOT ALWAYS BETTER. There are pros and Cons to using them both.

Imagine a FW as part of a Simplified GEAR BOX. Same Concept. Lighter FW is ONLY Benificial to you During ACCELERATION.
A car in 1st gear will Accelerate Faster than a Car in 5th gear SAME Concept.
It is a personal preference if a person wants to have a lighter FW, but One person says it great and NO regrets but another person says They didn't like the change in drivability.

I read a Post on this several months ago. They had a Poll and Most people preferd medium weight FW 9 pounds or more. I am running a Spoon FW currently and it is probably the Nicest for Street and Circuit out of all the FW I have tried. On the Circuit I change (sometimes) to a 7 pound FW But I would NEVER drive it on the Street. Especially in Traffic.

 

Get your stock wheel worked for a few bucks... 5kg is a good weight for performance and drivability..... Anyway, it doesn`t effect the acceleration very much (less than most people expect)..
I`m running my 5kg wheel for a year now and the best I can take from that mod is that revmatching became a lot quicker. And that`s the most important thing. Who cares for a few 0,0xx seconds quicker acceleration...ITR is a track car and if a light flywheel helps you to brake later because your revmatching is quicker, then it makes sense.... But don`t think "the lighter the better".

... Drivability is the most important thing.. it all has to fit to the work your feet do when you`re driving.

 

Just as 1 person would "never drive" a very light flywheel on the street, another person wouldn't even go back to a heavier flywheel on the street. On the street, it is very much a personal preference.

This is not true at all. A lighter flywheel makes rev matching faster and less likely to upset the balance of the car during a downshift. Both of these benefits are noticeable and valuable on the track.

Before you get up on your high horse, you're saying that a 50 lb flywheel yields the same effect as a 10 lb flywheel?

excuse me, tell me, what is wrong with a light flywheel in traffic?

if you want luxury, if you want comfort, go get a BMW and call it a day.

i would sure like some proof of this. evweryone talks abut differneces in the starter. well i have a JDM starter that came with my JDM motor and my **** still grinds with my JDM toda flywheel that came with the motor..

Maybe your JDM motor just sucks John. Just kidding. Here are some pics taken by HT member "cheezthis" showing the damage to the teeth of his Jun flyweel when used in combination with the USDM starter.


From what I have heard, the way to remedy this problems is to either notch the flywheel teeth or get a JDM starter.

Back on topic though...I had the Comptech 8.75lb flywheel and loved it. It was daily driven without any complaints from me. The revs drop a bit faster but lets you shift faster more smoothly-so that's a plus in my book. Improved throttle response and ease of rev mathching make a lightened flywheel an awsome upgrade...loss in HP or touque-blah whatever. Anyways, next on my list is the lighter 6lb flywheel because the stock ITR flywheel fee;s too heavy for me!
