a twin or triple plate clutch like that would probebly be the death of the gearbox from the shock torque loading that much clamp can put through,

can you get a clutch disc setup with a sprung center? maby just go for a single plate with a heavy clamp pressure plate, and sprung center disc and make the flywheel out of mild steel, also with the m104 if you make the flywheel too light you will get engine resonance/vibration through the car,

Huh? Vibration throughout The rev range? I-6's don't have that problem if they're balanced. They will get between one and 3 critical points where at a specific RPM they will "sing". But if you know them accelerating though the powerband and passing them as quickly as possible makes them less of an issue. I don't see how having a flywheel too light would exaggerate the issue. Having a heavier flywheel will resist vibration but also exaggerate the issue should the flywheel also reach a harmonic point. Lighter flywheels will not 'absorb' vibration, but they will also not place as much stress on the drive train and crank should they begin to vibrate.

i am using a very simerlar set up with a lightend 103 flywheel and the same clutch to the twin plate you have in the top picture on my twin turbo 103 12v 3.2 motor (104 crank). no singing, no vibration, just power

"some mods improve your car and make it into something it never was, other mods, however, although essentially the same, are not, and make that car a ricer"

if your car isnt shiny, you dont know what you are talking about, remember; paint shine = knowledge. In order to be taken seriously, you should spend all your money on paint, (and get a dyno reading).
Dont forget to polish it often

sup,Hows resonance in yours these days with that super light FW?

On the topic of lighter FW's,I dont race cars nor build them professionally but modification to my M111 with a lighter FW definitely exaggerates vibration under load and at the critical harmonic point(~2500 in my case),yes the I6 has much much better balance due cancellation of the rod/piston speeds but like any piston engine it will still produce vibration/torsion under heavy load,so a lighter FW will exaggerate this.
