Quick questions bout LTW flywheel..thanks!
1) can a ltw flywheel introduce premature clutch-wear? or am I offbase.
2) does it affect how you engage/disengage the clutch? like speed etc.
Sorry if Im a bit ambiguous.
2. Not if done correctly.... by that I mean that stock clutch take-up position can be retained as long as the throwout bearing dimensions are correct for the new flywheel. With regard to vehicle speed, an excessively light flywheel could induce stalling if you didn't slip the clutch to higher RPM. Excessively light for an M52TU or M54 is probably just below 10lbs. By staying above that weight, the only changes in RPM characteristics relative to performance and driveability will be desireable, not annoying :D
1) slippng the clutch at a higher RPM
- Im a bit confused lightening the flywheel increases rotational speed correct?
- I imagine that dramatically reducing the weight of the flywheel would make you go through RPMs quick, correct?
- Does lightening the flywheel reduce drivetrain loss in say dynoing or normal driving.
- errr does this translate to a more torquey feel?
---sorry if I sound fuct up, I am.
To my knowledge, a lightened flywheel would not affect the rotational speed, just how fast it gets there. Pretty much what is does is make it rev up faster because there is less weight for it to move. It's like how long it would take you to get a bike rolling (by pushing) versus a car in neutral. You can't push the bike any faster than the car but you'll get it to the top speed a lot faster. Okay, this may sound like totally giberish, I was just in the comp lab for the past 12 hours for a project.
reduces rotational mass... which
translates in less energy stored in the flywheel. when you accelerate the mass, you need to perform work, which is basically the energy required to bring the flywheel to a certain rotational speed. this energy is a waste, because it can't be used in any way... it gives it a high rotational momentum, which is basically, why the engine seems so lazy.
Another diasadvantage is that the energy you stored in the flywheel, let's say you're engaging the clutch ... and hm... for some unknown reason you didn't rev match... that energy will transform into ... either heat or a jolt forward... depending how smooth the clutch engagement is... the first is bad. uh... so is the second one.
so get rid of the heavy flywheel.
