well matt aparently you didn't read the thread title i didn't really care if anybody liked the way i and hundreds of others do it someone wanted to know the correct way and here it is your way might slip by in tech in but if you bet someone at a real race and they put up the money you won't be the winner anymore because the rule says battery disconnect and if that 2 gauge wire is hard wired to the battery it isn't disconnected i do not and will not care any excuse you give its still hooked up period point the end
Well I guess I'm NOT
wrong after all. I've become sick of this hear say BS and the I'm right your wrong with out anything to back it up crap. I sent an email to Bob Blackwell , the NHRA general rules commitee CHAIRMAN
, with a copy of the master cutoff diagram in question. He sent a prompt reply shown below.

nzane1980, if you want to further argue the legality of the the diagram you were bashing, contact Mr. Blackwell (his email is listed above).
I did not say that any other methods listed in this post are incorrect, only that there is more than one
