MSD 7751 - Legal?
 

This is a hand held two-step controller. I went to NHRA accepted and it's not shown as accepted or prohibited. I have a call placed with NHRA. Anybody know one way or the other?

Re: MSD 7751 - Legal?
 

If it is not on the list as "accepted" NHRA does not allow it to be used.....Until you hear from them I would contact MSD because they are the ones who have to submit the item for approval and you could find out if that has been done or not......

General Regulation 8:2

Those are the same dumb a**'s that asked me "what do you want me to do?" last week when I called to tell them my brand new MSD Grid was defective.
I did call MSD today about this item. Their response? Call your tech department.

Peter, what do you think their reasoning is for that? Wouldn't want you to be able to make a last minute change in or after the water box if you see the starting line is bald.
I can't really see a reason for that one.

Ed, the rule has been out for a long time and being able to change the launch RPM would be great.

Ed, this quote goes back to my 2000 rule book and probably further.

I still can't figure out realistically why seat belts in like brand new out of the box condition are only allowed a two year lifespan.

Ours is apparently, not to wonder why, just to do or dq.

Here's your answer....

See page 302/320 in the downloaded version of the 2013 rulebook.
It's in section 20, page 34 (General Regulations under Ignition).

"The use of any programmable multi-point rev limiter and/or a rateof-
acceleration rpm limiter, either by themselves (e.g., MSD 7561)
or integrated into the ignition system (e.g., MSD 7531), are
prohibited in NHRA competition."

These are the only two I see prohibited from msd.
7751 is not mentioned in the 2013 rulebook.

Spoke to Bruce Bachelder today and 7751 is legal. Pat Cvengros returned my call shortly after and confirmed also. I asked Pat why the RPM controller could not be within reach of the driver? I cited Ed Wright's example that you see everybody is spinning their tires due to a change in track conditions, so what's wrong with making an adjustment to help the situation? He didn't have the answer and said he would have to research the rationale. I said I've seen plenty of S/SS cars with a rotary adjustment dial within the drivers reach. I said "I'm sure that in the grand scheme of things this is a low priority issue" Sounded like he agreed but I'll order my 7751 tonight and make sure it's away from my stubby arms anyways.
