Can a forged crank be too light for a supercharged application??

I was sent the incorrect crank by callies and i wanted to upgrade to a lighter version than the magnum which is 48# to the 36# version...

Now i heard of someone braking the 36# crank into a few peices... should i stay with the racemaster crank which is heavier and probably beefier than the lighter one?

This is for around 700 and maybe in the future 800rwhp car (if it ever gets there).

 

Theres' no way I'd use a 36 pound crank in a FI motor I'd stay with the heavier crank for FI, especially in a supercharged application.
