Jut wanted your guys/gals opinions. Thanks!!

 

my argument: Why would you send to balance the pistons, rods, crank, damper, clutch and FLYWHEEL? why don't you send the tranny as well?

it affects the way the engine reacts, thus it affects the tranny....
just my way of see it.

 

a flywheel has a direct correlation as to how the engine reacts to throttle angle and fuel input..........it lets the engine spin up faster but with a lighter flywheel you loose torque

 

hehe, a lighter flywheel is taking mass out of the rotating assembly, thus making it more efficient and lighter/easier to spin.
you do not loose torque with a light flywheel...you loose momentum

 

Due to the fact that the flywheel has no actual effect on the actual operation of the engine (other than load), I have to consider it a drivetrain mod. You have to consider the fact that the only way any part of the drivetrain affects the operation of the engine is by putting a load on it. The only thing that's different about the flywheel is that it's bolted directly to the crankshaft, however that doesn't change the fact that it only affects load, thus making it a drivetrain mod.

 

If you think the flywheel is part of the drive train I guessing you think the starter is too?

 

Engine is inclusive of the drivetrain, so it's both. But what difference does it make?

No... drivetrain implies it is used in the locomotion of the vehicle.
Unless the starter is used to move the car, the starter is NOT part of the drivetrain, It's not part of the engine either
So I don't know where it goes

 

interesting, this debate is almost philosophical, is the flywheel a drivetrain or powertrain component? I like most of you am leaning toward the drivetrain side, but at the same time i'm not certain. it's not as simlpe as somthing like an axle, which is exterrnal and quite obviously part of the drivetrain, or a piston which is internal and obviously powertrain, the flywheel is right on the border, linking the two. if pressed for an answer i'd go with drivetrain, since, though it is needed to make the engin/transmission assembly functional, the engine it's self can opperate without it's pressance.

What I was thinking too. Makes the most sense.

If you guys are considering the flywheel a motor mod, then would'nt that also mean a clutch is a motor mod too???? Now that does not make any sense

 

actually the engine cannot operate without the flywheel.

You need to have one to start the engine.

I consider it a motor mod since putting a lighter one on will produce an actual gain in power. The flywheel does not actually improve the performance of the tranny, but rather engine output and throttle response.

Engine Mod.

Now thats getting a little picky. But once the motor is started, it is not needed to keep the motor running. So how could it be a necessary part of the motor for proper operation.

SO you mean to tell me that when they put a motor on a chassie dyno, they put a flywheel on there too. Weird, all the chassie dyno's I have been to didnt have to. Granted yes, something did bolt to the crank, but it sure wasnt a flywheel.

And how many chassis dynos have you been to exactly ?

I made my point in the REAL WORLD, where engines have flywheels attached to the crank... damn man... no wonder HT has such a rep for being populated with ignoramuses.

 

Not all cars need a flywheel to start them


not all cars need a starter to start the engine..

Flywheel = Part of Drivetrain


now what about alternators..
most cars have an alternator driven off the engine..
so it would be part of the engine..

but what about those (race cars) which have the alternator driven off the driveshaft. is the alternator then part of the drivetrain?

 

*The alternator is part of the charging/electrical system

ah ha... but the drivetrain can be disengaged from the engine.... of which the flywheel is not connected, so it's constantly part of the engine. But I still say... adding an aftermarket flywheel creates horsepower and does nothing measurable for the drivetrain... so if I would choose one... I say engine.

I vote for this one. Can't argue with the video game manufacturer

No, you are incorrect. If you could rig up a system to put the starter on the crank pulley, then it would start just as well. And the flywheel will not increase the power of the engine, only the response due to the fact that it only affects the load on the engine.

 

does it really matters?
