Dtire = 23.9722
Rtire = 11.9861
Rfly = 5.57
M1 = 7 * (1+ 0.5*(5.57/11.9861*3.133*1.16*4.1)^2 = 174.8136 lb = 79.29kg
M2 = 7 * (1+ 0.5*(5.57/11.9861*2.045*1.16*4.1)^2 = 78.4978 lb = 35.6kg
So that equals to about 80kg weight saving or 17bhp increase in first gear and about 35kg weight saving or 8bhp increase in second gear.
Sounds very nice!!!

Nice find! Using the theory in the related article, i have calculated the effect of using the 8lb fidanza flywheel on AP1:
Dtire = 23.9722
Rtire = 11.9861
Rfly = 5.57
M1 = 7 * (1+ 0.5*(5.57/11.9861*3.133*1.16*4.1)^2 = 174.8136 lb = 79.29kg
M2 = 7 * (1+ 0.5*(5.57/11.9861*2.045*1.16*4.1)^2 = 78.4978 lb = 35.6kg
So that equals to about 80kg weight saving or 17bhp increase in first gear and about 35kg weight saving or 8bhp increase in second gear.

for s/c applications the lighter flywheel will improve the heavy flywheel feel the s/c gives and for turbo apps you will spool quicker
I was wondering when the "torque loss" debate was going to come up. Im so glad that website was posted, i actually looked for it when this thread first came up just so this argument wouldnt start. Ah well.
I had a fidanza flywheel and clutchmasters clutch in my h22 accord. That setup kicked ass. I'm swapping my ap1 for a fidanza at the same time when my clutch goes bad. I've got a fidanza and exedy combo in my 240sx as well
