Just read on another site that Comptech is releasing a chromoly flywheel any day now
for the TSX for those interested. No details yet. Source: Nate from Comptech.

 

Oh!!! Now this will get interesting...

 

hmmm i wonder how much will it weight and i also wonder how much will it cost hehehe

I'm offended they would post on honda-tech, their TSX forum is probably the most dead one on the entire site.

 

so what. He's a member there so he posted. You would rather he not post it any where? He probably won't sign up to this site(IF he even knows about it) just to post that as spam.
It'd be better for him to stick to one site that caters to ALL the cars they make parts for.

 

wht does a flywheel do?

 

your kidding right?

 

The flywheel helps the engine's crank shaft maintain momentum and aids in idling. A heavier flywheel will aid in torque (pulling power and acceleration), while a lighter flywheel will aid in top speed but may cause trouble with engine idling.


also might want to check this link out. great website for how things work, helps me out.

hahaha....no im not. im a total noob to all this car mod stuff.

 

umm .. never knew heavier flywheel will aid the torque, from what i know from centrifugal force is that if a heavier flywheel will take longer to spin up to the same speed as a ligher flywheel and vice versa. heavier fly wheel is more towards gas efficiency i blieve b.c it taks longer for the motor to decelerate, hence your car travels a bit further then a lighter flywheel.

i could be wrong.

pretty much ligher flywheel lets your needle gets to red line faster than a heavier flywheel. and since it's an acura/honda motor .. we alllll love that!

 

 

So what would be some CONS of getting a new, lighter flywheel?

 

Assuming it's designed correctly and weighs enough there shouldn't be any. If it's too light or poorly engineered you can sometimes get gear rattles or rough idling. Lighter flywheels can also make it easier to stall your car.

 

I Don't think we'll be running into those problems with Comptech.

 

yup! comptech products == no worries

 

im hoping for about 8-10 lbs for the new flywheel i wouldnt want to go much lighter than that when im going under boost.

 

I weighs 10.5 lbs. and retails at $349 USD. They are in stock right now. That is probably a good weight (I don't know what the stock weight is) as a friend of mine has a CRX with a 7 lb. flywheel and has rough idling.

 

350 USD for a flywheel... whoa
not used to that, anyone think it would be worth the dollar?

 

anybody know the weight of the stock flywheel?

 

Just in case you guys are intersted:

T = I x A where T= Torque & I = moment of inertia and A = angular acceleration. In order to increase A, you either increase torque or decrease I. In this case, a lighter flywheel = lower I value therefore it will help you achieve faster flywheel spool up and hence faster acceleration off the line. I don't think it helps with top end speed though...

 

I guess you do learn something new everyday. Thanks a lot!

 

$350 isnt bad for a flywheel considering its the first on the market.

It won't increase top speed. Only change the gearing will do that.
I think this thread tried to get a little too complicated. A lighter flywheel has the same effect lighter wheels do. The lighter, the more acceleration. The effect is more dramatic @ the flywheel than the wheels b\c the fly is connected right to the crank.

 

Also the engine is way more responsive when you've got the clutch in and trying to match revs.

 

im gonna get one but im gonna wait for some clutches to come out first might as well replace both while i have the tranny out =)

 

would the flywheel only apply to manual transmissions or could it also be used on auto transmissions?

 

I'm also looking out for a clutch. Anyone here drove an STi? I loved how the clutch grabbed on that car. No slippage at all and very short pedal travel to the floor.

 

Only on manual trannies. On an auto trans, it's just pretty much a flimsy disc weighing barely 1lb.

 

cool. my friend has a fidenza flywheel on his integra type r, the needle shoots with a minor blip in the gas, but yea, you have to give it more gas or will stall out.

makes the car a lil harder to drive in the city, but not much

 

anyone think the flywheel might not play nicely with the DBW? Since the DBW gives some slight throttle when you let off the accelerator, would the revs shoot way up w/ a lightened flywheel?

 

probably not that bad. maybe a couple hundred rpm, but i wouldn't be worried about it.

 

I'm also gonna wait for a more compatible clutch to become available since the flywheel will probably rip the stock clutch apart. I got all giddy when I heard the news but have to remember I'm driving this thing everywhere, everyday.

I am, however, doing a few mods in the coming weeks - Injen CAI, Hondata Gasket, Comptech Short shifter, and Comptech rear sway bar (Sorry I'm gittin all giddy agin!)
