I have two possible flywheel options to sort out and thought that the list might help in that regard, especially those who are (have) running lighter components. Have a lightened steel post 60k flywheel at 16# and will be using a lightened ring gear at 2#, Luk diaphragm pressure plate 10#, McLeoud clutch disk at 3#, and flywheel/PP attaching hardware at just under 1# for a total weight behind the crank of 32# with this combination. The other option is a Fidanze AL flywheel at 11#, and standard ring gear at 3# with same ARP attaching hardware, PP and clutch disk for a total weight with this arrangement of 28#. There isn't much weight difference (though if I used the lightened ring gear on the AL wheel it would make the total 27#) between the two combinations, but I am told that reduction in rotating mass behind the flywheel can make a disportinant difference in take off.................obviously both conbinations are at least 15 to 20# lighter than the original TR2-3B setup. Thoughts, recomendations, comments, etc
Thanks,
Dan
