Ok so when Im driving and my car bogs down at a certain speed (45 MPH). No matter what gear im in either 3rd or 4th gear. it feels like its sputtering. Can flywheel hotspot cause this?

Doubtful. The big concern about hot spots is smooth engagement from a standing start. Question, if you accelerate hard does your RPM increase w/o a corresponding increase in MPH? If yes, = slipping = not good. W/O M/M/Y/Eng hard to know what you have, might want to call our Tech Support 800-258-8312 press 4, 8-5 EST Might also be an engine performance problem, that is out of our area of expertise. Gary

what causes the Hot Spot and how can i avoid it.

@muddack burning the clutch. ie. driving around with your foot resting on the clutch pedal, doing a burnout but really just burning up the clutch, reving the crap out of the engine and then slowly letting the clutch pedal out will also do it.
your basically super heating and 'hardening' blotches on the flywheel..

@muddack This was edited from a training video we did. F/W is Dodge Cummins. The hot spot is from extreme heating clutch slipping or being allowed to slip by driver. Martensite is created at about 1500 deg F and then quenched by the surrounding "cold" F/W mass. Results in hard brittle surface that also takes up more volume than base material. How to avoid - minimize the slip time that the clutch is exposed to. If clutch slip is detected, reduce load on clutch and repair. Gary

why don't they heat treat these before hand

@rcflyerman Because then the clutches would slip from new. Hot spots cause slip because they are "hard" and "slick", the rest of the flywheel is "soft" and "grippy" in comparison.

Wow I never realized that the metal actually undergoes a transformation. Figured it was just discolored and built up a tad bit.

What about a ceramic-metallic clutch?
Would it ever need to be replaced?
