I've changed my plans for a V8 conversion and decided to stay with a hopped up 2.0 instead. I'm considering a lightened flywheel since my impression of these engines is that they're somewhat doggy off idle. The drawback, of course is that standing starts become more of a challenge due to the lack of "flywheel effect".
In a competition environment this isn't much of an issue because hopefully you only have to do it once, but in a driver, especially in city traffic this could be an issue if you have to rev the engine and slip the clutch every time you want to get under way. Anyone got any experience with lightened flywheels in a 2.0 and want to shine some light on the issue? Tom |

Flywheel lightening is not a black art...its actually pretty straight forward.
Our flywheels are unique in one aspect. The measurement and relationship between the flange that the pressure plate bolts to and the flywheel friction surface needs to remain within specs... I have seen many super light flywheels with a majority of the material between the pressure plate mounting bolts removed. You get to light and you need to feather the gas pedal at idle just to keep in running. 11 Lbs is probably the limit of how low I would suggest on a street/autox car. 8-9lbs is on a race car with a race clutch. I believe the stock flywheel is around 16lbs. Rich |
