Another flywheel question
He doesn't need all that rotational inertia.
Way back in the day, guys were running 60 pound flywheels. If you like to google search, look up video of old Modified Eliminator stuff (when the NHRA killed Modified they started their death spiral) and watch them do a burn out and dry hop. Listen to how long it takes them to wind up. And to slow down.
Swinging all that mass around with the strokes that guys are using today just beats the hell out of everything. I used the lightest FW I could find. And I don't run near a 4 inch stroke.
I suppose if you would find a 20 pound steel wheel that would be ok. I run an 11 pound wheel. I'd hate to have to tune the car with a 20 pound wheel.
