you're getting too complicated for him.

you are starting with the exact same torque, with an OEM flywheel, a lightweight, or a ****ing paper plate. the engine output is the same.
It isn't the engine that's outputting toque, it is the flywheel outputting toque to the drive train. The drive train doesn't connect to the engine directly. So torque or the flywheel is the only real torque that affect the wheels.

yes, exactly. the OEM flywheel has a greater unsprung weight, meaning the engine has to work harder to spin it. and thus... theres your fuel consumption concerns.

Question for you:
Are boobs and hands polarly charged, thus causing the inevitable joining of the two? If so are some breasts simply charged backwards?

On a scale from 0 to 24...wait, 3 to 24, where 6 is the lowest and 12 is the highest, how freaking high re you right now?

She's got you high, and you don't even know yet.

question, goingnuts.. have you EVER actually seen the back of an engine, the flywheel, the clutch, pressureplate, or transmission?

84k miles disk and plate

Replaced/DIY my clutch disk and pressure plate at 84k. Lots of life left in the clutch disk. Bearing was OK. Pressure plate SAC mechanisim froze/failed leading to slipping and nasty clutch judder. Pressure plate warped - see gap beneath machinist rule in attached photo. Same gap 360 degrees. DIY replaced/rebuilt everything.

My Ride: not an E46
previous owner lived in NYC and changed clutch at 50,000 miles
traded the car in to dealership, and i bought it at 98,000 miles
I'm super good to my clutch but it seems its beginning to wear a bit. Its really soft. No slippage though

Once the inertia is over came, the torque can be maintained with lower force compared to a lighter flywheel. On highway driving, you can supply a large amount of fuel at the beginning to over come inertial. Then you can keep that ticking over at relatively smaller amount of fuel compared to a lower torque flywheel. So the choice is what is better: a large one off hit of fuel or constant increased fuel use once the car is cruising ? For non-racing cars, the former is better. You must bear in mind a lighter flywheel will need to spin higher to attain the same pull as a heavy one, and that is where the fuel will be going.

i like how you skipped my post schooling you in the art of flywheels.

carry on making an ass of yourself. dont admit you were wrong.

he must have me on ignore list

Clearly I have and you haven't. Otherwise you would know the wheel get its torque from the flywheel and not the engine.

oh, OP...

on lifting the transmission..
be wary of the dial pin on the starter, its a *****.
i have to bow to Chuck Waits because he literally got under my car, put the transmission on his chest and inhaled to lift it.
him and 4ngie's husband Matt spent a night working on my car, and i cant thnak them enough

oh yea, but your posts are so useful


try reading it again, slower this time. maybe you'll understand how the mass of the flywheel affects acceleration.

youre right. i don't know what im talking about. ignore the fact that i have replaced the clutch on my toyota, nissan, and aided in the work on my bmw.
i have never seen an engine in my life. nor have i rebuilt my vanos unit, replaced my diff. im just a drooling idiot.

this just keeps getting better and better. this guy has to be a troll. can we just get him banned? the overall accuracy of information provided on this site would increase dramatically.

where can i buy these torque producing flywheels in london? is that some sort of special part you Europeans get? if so, i want one. then maybe i can have over 9000 horsepower.

Hey, you guys hijacked my post!! (But this is getting interesting...)

From what I'm reading, it seems like both sides of the argument are essentially correct, in different ways. It seems you're both describing different sides of the same coin, and different truths in different conditions, but are not combining them to form the greater picture. Not to take sides, but a lot of what GoingNuts is saying seems correct to me, particularly his last statement about energy input during initial acceleration vs consistent cruising. Let me think about this and get back to you.

People can do all this stuff without knowing why or how it works. That's obviously what is happening.
