My weight reduction

THe first flywheel they sent me had the bolt holes machined improperly. I'm sure this is a rare slip up as fidanza is a very reputable company from my experience. They overnighted me a 2nd flywheel and it lined up perfectly. No complaints at all. The engine runs through revs real quick. The only thing i'll say is that i can hear the clutch basket chatter a lot more now, though it might also be because i have stiffer motor mounts now.

According to Kozmic, he doesn't recommend lightweight flywheels with big cam/big injector setups due to extreme difficulty in a proper idle. But i don't care :)
Stupid Question, how did you know the bolt holes were drilled wrong did it just not fit or it didnt look like the OEM one? (Sorry kinda new with the drivetrain stuff). Thats cool they sent you another one that fast tho!
They do seem to have a good rep. Thanks for the info I may look into them some more.
 
well 6 out of the 7 bolts went in and the 7th was offset by like .08 inches. It became frustratingly obvious when that last bolt couldn't line up to thread into the block. I debated milling out the bolt hole on the flywheel but decided against it as the flywheel was already balanced and i had no way to balance it after machining. So i took pics of the misaligned bolt holes with calipers, sent it to fidanza, and i had a new flywheel the next day.
Ok gottcha.thanks !
