Two/three step wiring/functions(stick cars)IHRA!

terry1 · 12-11-2007, 07:19 PM

It would appear that, if you have a lineloc wired to your shifter,you will have to have a switch wired in/on your clutch pedal to activate your launch rev-limiter(if you use one,and I do).
Do "they"not realize that if this is the case,every time you depress the clutch your rev-limit will be activated?
You could wire a self/locking relay to the launch rev-limit,but this would require another on/off switch to go with the other one's most people have.
I don't think that the" powers that be" would like a bunch of relays that they would have to check for possible illegal connections to delay functions,or other "things".
Anyone else out there disgusted by this new irritation,especially after spending countless hours to wire your three step set-up just right?

Have you contacted IHRA with your concerns? And I do agree with you. Also, if you go this route, I believe you may have to re-adust your micro switch every time you re-adjust your air-gap because it would take more or less travel of the clutch pedal to release the clutch. Agree?

Your right Jeff.This would be just another,not necessary,pain in the ***,adjustment required on a very regular basis.Just like the muffler thing a few years ago,do "they"not realize the the waist of time it will take to redo,in my case,and I think I'm not alone,a excellent job done to my (wiring) in my car to get things just right with no intermittents.I suppose that a record function of a play/back tach,that has to be armed,also can not be a function of my/anyones stick switch.If "they" think we are such sneaky/cheating/.underhanded/(fill in any other adjectives) racers,lets go the IROC route,build us cars and away we go ,all on a even keel.

most class racers are shifting clutchless. i use clutch on every gear change and ive got a clutch lever mounted switch and ive never had a problem with rev liniter coming on during shifts. i just tap the pedal anyhow. on gear changes...i guess it depends on your driving style...try it first

Ok Castle so at the end of your run you just back off the throttle and pull off the track? I push the clutch in oops just went from 8000 rpm to 6500 (if I had a swich on the clutch) and coast off the track. Several stick racers talked to Bruce at the Vegas national race. We thought he understood the problem or lack of one as pertains to the line lock two step issue for stick cars obviously it didn't make it to the rules makers. We need racers involved in the rules process and not just the sludge-o-matic racers.

Is it possible that if us stick guys(and gals) got together and individually sent our concerns to IHRA(don't get me started with nhra) they may actually listen?
