Stock Piston Acceptance
 

For having a new piston accepted by NHRA,do you send it to the same PO Box with ATTN: Stock/Super Stock Commitee? It`s been a while. lane

The piston manufacturer must submit samples to NHRA for approval, and NHRA may require an unmodified OEM piston as a control sample, if they do not already have one.

I've been through the piston approval process, NHRA put us, JE and me, through the wringer, for 6-9 months.

mind sharing the story?
might be handy to know what to do and what NOT to...

Re: Stock Piston Acceptance
 

Everytime I`ve done it,I bought a piston and sent it to NHRA. Would normally hear back from them in a week,and receive the piston back I sent them in about two.

That was my experience.I sent an off the shelf Badger along with a stock piston to Jim Skelly.The approval came back showing minor differences but not enough to disqualify
the use of the Badger.I would guess the process is much longer if the piston co. has to custom make a piston.

I`ll just send it to the PO Box,and hope from there.

Took a little while,but got a call today from the Tech Dept.,was asked about the combo(my mistake for neglecting some info,like I said,it`s been a while),and a return call about a half hour later. Piston was accepted.
