Hey, at work and just wondered if anyone had the depth specs for the 2.0 flywheel? What's the stock weight too? My last flywheel had been lightened, but I didn't weigh it before selling that car. I LOVED how much faster the shifts were and I didn't mind having to bump the idle a bit. Making a little short-stroke beast, and I'd like to lighten it up a bit. Recommendations (I'll spank you if you say, "keep it stock")?

Roadglue was asking for the 2L spec above. I haven't been able to find the depth spec. easily, - it is not mentioned in Porsche's little spec. book. RIMCO quotes .853"/.857" which equates 21.66mm/21.77mm. Measuring the 4 core flywheels in my shop, I get right around .889" = 22.83mm. - or a bit less. factoring in wear, I tend to agree with the 22mm. I'll cut it to that then. I would have expected 22.5mm though. I have never known a VW or Porsche flywheel step to be some oddball dim, - always in whole or half mm. - A lot of machine-shops will cut the step on the low side, giving the cover an extra little pressure, anticipating wear, and still be good. I suspect that is why these off dims are listed in the AERA book. The Porsche 228 flywheel is solid steel, the 228 VW is soft cast iron w./ steel ring-gear. - I'm sure you know. With respect to the lightening procedure, weight obviously should be removed from the perimeter, never from the back of the friction surface. I would NEVER run a 10lbs flywheel in an opposed 4. - in a 6, yes, but not the 4. The stock weight is right around 18 lbs on my handy dandy 'not legal for trade' scale, I'd go with 14lbs, retain a little flywheel effect, and still have an engine with improved throttle response. What do the 'Gurus' sell re-man. lightened, balanced flywheels for? |
