Delay Box Tach Wire Now Accepted
 

I was looking at the new NHRA rules revisions for 2014 and it looks like we can now use the tach that is built into some delay boxes as long as we are using an approved box.

Did anyone else notice this?

They also seemed to have gotten rid of the single wire from the trans brake switch to the solenoid rule too.

Interesting..Just read that, they crossed out that entire section under the 2014 ammendments. I will ask in Phoenix for sure.
