Re: Super Class rule clarification
I have witnessed this one time and the driver was given the suggestion of changing the rear gears and not having the issue by NHRA tech.
The driver was warned as the limiter was a rpm limiting device before the finish line and was considered to be illegal used in that way. Limiter devices are considered safety devices by NHRA tech I would guess. I was just parked nearby when the tech personnel visited the racer. Just What I Witnessed |

Re: Super Class rule clarification
No Freddie....you can't hit the chip on the high end....intentionally.....(it does work though)....but you would be turned in in Div 3...and I bet my Div 2 buddies wouldn't be happy either....
on the Fi question.....cutting the fuel is fine as long as you close the throttle some amount....with a linkage stop or something similar....just cutting the fuel would be suspect and sooner or later someone wouldn't like it....I'm not making the rules...only giving you my opinion....nothing else...

I dont know how much of a issue it will be because I have never run it with a stop on it, and the car will definaly need to be slowed down.... I have been 9.2's so far, and thats with hitting the chip.

Re: Super Class rule clarification
When I set the car up it was set up in NMRA H/S trim with a 363 small block that will easily take 8500+. car has a 4.30 gear in it now, and a little smaller 363, I could not justify spending the $$$ to try NMRA anymore as they have gotten WAY out of hand.
New motor I would like to keep around 7500 so it will last longer. Car is still running the 28x10.5's and sitting at 2650 race wieght. I changed converters this year also, I can go red on a .370 tree with no issues, car has been 9.teens, and usually runs through the traps at 8800. For local bracket racing I put a 7000 chip in it since almost everything brackets now is on the 1/8 it didnt matter... I was thinking about putting the 3.73's back in it, and just let it kill off the first 100' or so... then see how much more I need to slow it down to run S/G..

Re: Super Class rule clarification
Chris: I realize there is no "SET" RPM limit on any motor, however when using FORD's you really dont want to push them much over 7500 for long unless you have a killer bottom end.... Unlike the Chevy, they just cant take the RRR's...
Like I also posted I dont know even if this will be an issue as I have not run the car on the stop yet, and will need to in order to run either S/G or S/ST..
