Soup up trick.
 

1/2 cup nitro in the pan is worth about .04or 03. One cup blows the rods out the side. You know when you passed the line is when you can reach in at the end of the track and pull out a piston. Just a thought before Indy.

.03 to .04 pick up is only if you use the cheep stuff nitro, it has yellow die in it. The clear nitro (faster) is the way to go, its Indy, spend the extra $$$$. It's a bracket racer dream: " Go fast or go home".

Re: Soup up trick.
 

I'm sure . I was trying to help Jeff to keep the rods inside the motor.
Of course you'd have to look long and hard for the ports on those "factory" combos.

James is right. I was told several years ago, at Indy, that Buster shut off two SS/AA hemi cars on the starting line for a nitro smell in the early 1980's.
