Just installed a ACT street disc with a exedy 8.8lb lighten flywheel. I just broke in the clutch and flywheel but the car feels slower than before. It seems to lag when I full throttle it. I had my mechanic put it in last week. Any suggestion?

 

um a light flywheel is going to actually make ur car quicker because its going to rev alot faster. if it seems to "lag" maybe u dint the lightweight flywheel? because if u get a heavy flywheel its going to take longer to rev because it has more inertia but it's also going to create more torque

 

maybe you messed up a sensor or somethin cuz me and my friend put a 7.5lbs. flywheel and stage one clutch in his 97 gsr, and i feels alot better than the stock one. it revs alot quicker and feels alot more responsive above 2 grand

 

I'm not sure what it is. I broke in the clutch and flywheel at 300 miles. I know, people say it's got to be 500 miles. But when I look it up in the ACT forums, it says only 200-300 miles for break in.

 

is it really true that on the ACT 4 and 6 puck disc clutches that the break in procedure is 6 hard launches?

but it is also going to have more trouble gaining momentum for going up hills and such... you will feel a difference in power, as in loss going up hills and downshifting wont slow you down as much as with a stock flywheel....

No break in for a clutch is launching it 6 times.

 

maybe you're just not used to launching with the lighter flywheel, yet. it took me a while to get used to it.

also, to my knowledge, pucked clutches don't require any break in.

 

any suggestions to the lag on my flywheel?

It depends upon the friction material being used, but as a general statement, almost all pucked clutches are using friction materials that don't require any real break in.

Improper installation maybe. The mechanic did install a fresh pilot bearing and throwout bearing right?

-Kendall, who's been happily running stupid lightweight flywheels for quite some time

a flywheel doe not create more torque. the eninge crated the torque. putting a lighter flywheel in is akin to putting very lightweight tires and rims on the car. less rotational mass keeping you from getting the engine up to speed. i did not know that they made 8.8lb flywheels for the integra. wow. i am a big package diesel guy. we put in 400-600lb flywheels all of the time.

He's the best mechanic where I live that knows about Hondas and Acuras. I didn't ask him, but I'll do so on monday. The RPM drops alot faster now that I have the lighten flywheel. I know that the RPM is suppose to rev up faster and drop faster.

 

just asking because i remember hwen my cousin got his act 4 puck in his gsr it only had 21 miles on it and we were leaving my house and we were doing about 30 and this prelude came up behind us and it opend up into a two lane and we slowed down to 10mph and my cousin launched on it hard as **** and we waxed that proludes *** baad. just wondering because i thought it wuz very odd that he would ahve done that to a brand new clutch

 

that's weird. it should rev a lot faster.. and you should notice it. How does it feel above 3k?

 

maybe you didn't break in the clutch properly...not saying that you didn't but it's just a suggestion. maybe you didn't and now it's slipping or something.

not beating the **** out of it yet and waiting for the clutch pedal feel to either soften up if hard or harden up if soft. this is just how i do it.

Thats right. The people that started that myth are the same that said more backpressure more torque.

Might wanna try resetting the ecu if you haven't already. Just pull the fuse for a few minutes, or the neg terminal on the battery, start it up and let it idle for about 5 minutes a/c and accessories off, not touching the throttle, then shut her down. Then start it up and drive like normal.

When I got my car it had a modded intake and exhaust and was never reset. The idle moved around, and was never steady. After a reset, and it learned itself it's been fine ever since. It's been like 3 years now. After every mod I reset so it can relearn.

It's just inertia. The engine's rotating assembly essentially weighs less, meaning you just can't dump the clutch as fast as before, but aside from that it's just a matter if getting used to it. It's not necessarily trouble.

The less weight is easier for the friction of the engine to influence, so downshifting will slow you faster, but it's not really noticable. I'm a chronic downshifter.

Also a chronic speeder but thats for a different thread....

If you put X friction to an 18lb. spinning wheel, and a 12.5lb. wheel, or 8.5, going the same speed, the lighter wheel will stop faster.

 

butt dyno doesn't say anything...

and i guess in this case the dyno wont either

that onyl applies if your actually trying to downshift and not gas it...which prolly be apply more to engine breaking ...

The rpm jumps faster when you drive it normal. But when you gun the car, it lags. The clutch grabs good, it's not slipping or anything like that

 

maybe u just got a peice of **** flywheel????????

 

Check to see if you're clutch cable if so equiped is tight enough and has enough play to properly engage the clutch. And if it is hydrolic, maybe adjust you pedal or whatever you can to adjust the line (not familiar with hydro trannies).

 

maybe your mechanic didn't install the lightened flywheel.
