Guys

I friend of mine asked me to post some questions.

does a 6 1/4 dumper is too small for a lightened 250 crank (12lbs lighter) ? if so does a 8" TCI dumper is big enough?

What is the best dumper avaliable? TCI, Fluidumpr etc?

he will be using super rods and JE pistons, because of that is it adviced to lighten the crank?, or for a hi reving turbo application (1200HP) the best is not lighten it?

as the rotating parts are lighter, how can he calculate how much lighter the dumper can be?

My friend thx a lot!!
