Not in mine (2nd edition), but it's in his other book- How to Modify Your Mini. :wink:

I have that book, but do you really want to shave it off.

There are three types of flywheels, and the best one to use is the big solid one piece one. You would think that lightening a flywheel has a benefit, but youll find that the heavier flywheel actually works better.

Get it balanced at an engineers and bobs your auntie your ready to go.

Better as in allows your tractor to plough your field more smoothly?

A lightened flywheel makes a big difference to the rate of acceleration.
It really is "cheap horsepower" and should be one of the first items on the list of anyone looking for increased performance from an engine, particularly an A-Series.

I reckon the real problam is that it's stuck to a crankshaft and has a busted thread, I reckon i know someone who might be able to fix it :wink:

if your racing the thing then yeh fair enough, if its a daily driver then easier gear changes and smoother deceleration. Guess you got to work out the trade off.

My friend lightened my flywheel as per vizard years and years ago, I think it worked out to be 1.3kg lighter than standard. I drive it every day and don't' have a problem with it - I want to go lighter for khanas

I did this excersise a while back

At the time I remember calculating the apparent difference in performance is like having or not having a passenger in the car.

.. but the rationale is. Lighten the reciprocating masses and the engine 'sees' a lighter car and can accellerate harder.

Just buy Aaron and Doogie some Krispy Creme's - It'll work out cheaper.

completly the tool manufacturers fault for cheeping out and not using high tensile bolts :shock: :shock: :shock:
