Super Gas
The .4 reaction times you were seeing are common because super gas is run on a .400 pro tree. If you are not .400 something on the tree, you are going home. .3-- something is a red light. You will want to do some serious homework before jumping in to super class racing. Very competitive,and very sophisticated for some. Can be done with older equipment, but takes a lot of work and some one who can "drive the big end". Stil boils down to who has best package. I certainly would like to try it some time. Let us know how you do. Good luck.
