I'm thinking about doing a Lighten Flywheel for my car, but I wanted to know if it would be worth it. I did a 61mm TB last week and I noticed nothing. I would do the flywheel mod if someone could compare to another mod. Is it as noticable as and intake, or pulley? If its anything like the pulley then I will get it this month.
Thank you

Mario,
Where did you get your throttle body?

 

a lightened flywheel is definitely something that you will notice. The engine will respond much more quickly to a throttle input. Revs will climb faster, it will feel like your car is a bit lighter, particularly in the lower gears.

 

it is similar to a lightened crank pully.
the lightened crank pulley takes some weight off of the crank.
the lwfw does the same thing it just removes more weight.
the mini revs a lot more free and acceleration improves.
by the way, its more noticable than the throttle body.

 

I'd seriously consider an aftermarket clutch/pressure plate combo with this.
More mass lost.
Yes you will notice a difference. If you went to lighter wheels/tires the effect will be much the same under straight line acceleration.

 

How much does the stock MCS flywheel weight? But yea, flywheels usually make a huge difference.. Car will accelerate faster, revs will climb up and down quicker, which means they'll drop lower inb/w shifts... but quick shifts solves that problem..

 

I think the stock MCS flywheel is around 26 or 28 lbs.

 

this is correct... with the preassure plate and clutch disc it's almost 40... which is crazy... especially when you consider the total wieght of some of the setups for reduction are like half that...

 

so what do you think...is it worth doing? if so which set up do you like for a street car that gets driven aggresssively, autox some and a few track days

 

I have always said this is worth doing... especially over a crank pulley... as I belive in having a damper... I have already seen rods come through blocks from no damper... but I would recommend the 06 crank pulley as it's some 2.X lbs lighter than the 02-mid 05 cars... yet still has the damper...

I like the exedy... it's not cheap though.... but I also belive you get what you pay for... oh oh and it's pretty!

they also make a OEM replacement... but this pic is of the
Exedy Hyper Single Clutch Kit

 

How harsh is the engagement from the Exedy? They are flywheel / clutch combos, correct? I am aiming for a setup similar to Bobs over the winter (m62 and such). What would be a good choice for me but not be overly harsh in engagement.

funny you mention it....I am looking for an 06 crank pulley if someone has one......with all the light weight pullies someone should have one

 

I find its much like stock... obviously different.... but not anoyying or harsh

 

That's good to hear.
Do you have a weight for the full combo?
Are there clutch options for this? Full race is a bit tough on the street so something a little milder on the friction front would be nice

 

the wieght is 25 I think for the whole thing....

they make a OEM replacemetn.... I have not tried that.... but the one above is kinda all around...

 

Any downside to this? with the exception of $$ of course?

Any problem with distortion or worping?

Do you recommend a "lightened" flywheel being machined from the stock flywheel or going to an aluminum flywheel with steel surface inserts?

 

Accually that's why I went with the Exedy.... cuase it's a chromoly flywheel.... so no ring gear to come flying off... and super strong... but still light...

 

Very nice...thanks

I could only find this one though;

The issues I've always heard about are rattling at idle, and street drivability is affected.

 

Hi Guys

Months ago I had been looking all over the web for a Flywheel/Pressure plate kit and came across all the usual suspects of Fidanza, RPS and UUC. None had or could promote a proper matched kit tried and tested, with the exception of RPS perhaps. Finally I came across the then newly released Exedy Hyper Single, which I have had on my car for about 4 months now. My experience with Exedy clutch products are single and twin plate kit for skyline, evo and rex but since Exedy do not make a twin plate kit for the Mini it is not relevant for further discussion here. In a nutshell the feel of the Hyper Single is exactly the same as in its application for the cars mentioned so if you have any friends with like cars and kit just ask them how it feels.

Here I'd like to share my experience and feel using it in my MCS:

Pedal pressure: Stiffer than stock by upto 70%. Doesn't feel like it now but it did then when first installed! I guess over time I got used to it so it feels normal.

Clutch Take up and Driveability: You can slip this clutch but it does not like it, its ceramic petals has an almost on/off effect, bite point is similiar to stock but more immediate. Not suitable in slow stop and go traffic. In effect this is what is meant by it affecting the driveability of the car.

Throttle response: For me - perfect. The stock set up made the engine feel lethargic and "fat". With this kit the engine is more than noticeably preppy like a Jack Russell if you will, like its constantly saying "Can we go now? Can we go now? Can we go now? Can we..." if you know what i mean..

Clutch Noise: It rattles but not by much more than the previous stock kit on my car. It certainly rattles much less than the UUC flywheel and if you dont mind a slight rattle you wouldn't hear it. If you listen for it, its there. The music drowns it out for me.

Downside to me: In a tropical climate like where I'm from Air Conditioning is a must and is usually on all the time but with this flywheel the revs comes down so fast the engine usually stalls when releasing the clutch during a slow gear change e.q. in traffic. I have had to replace 1 A/C compressor because of this - the bearings jammed due to the many rolling bump starts I had to do. Switching the A/C off solves this problem, so in traffic the A/C is either off or I double declutch.[SIZE=2]

In Summary: I can easily live with the downside as the car is mainly for weekend fun use and it is a load of fun! This conversion is well worth my money and has really heightened my enjoyment of the car exponentially. I would rate it as good as changing the pulley as the engine response has much improved. I wouldn't know if it would be worth your money but I highly recommend this mod. for the fast road driver/ track/ autocrosser.

Im not very good at this so if anyone has any questions I can help with please feel free to ask.

Mixed Nuts

 

Wow... this is definately not for me then, considering traffic jams are common in my tropical (always hot) country! I can't imagine being caught in a traffic jam, with my aircon OFF! Heads will roll....

 

who has the best price on this FW/clutch combo?

 

I've been watching to see if they come down... so far the best price I've found online was e-bay $1,152 ("Megatuning Motorsports" (?)). I was planning to do this at the same time as my LSD project. Maybe we can get 2 for $952ea .

 

That sure is a lot. You can get a UUC Flywheel from PRO-MINI for $420 and a Spec Clutch for $319. -- Johan

 

another problem with lightweight flywheels is the loss of torque. With less spinning mass your car revs quicker but looses the momentum created by that said lost weight.

For people with moded cars you will most likey love the results.
