Not subscribing or unsubscribing to conspiracy theories....however, I would like some opinions on this.

WIth a grid, you can set a safety RPM limit to come on at a pre-determined time after a trigger point. For instance in my super class cars, I have this set at 12 seconds after the trigger point (transbrake released). It is set at 12 seconds, as this is SC and SG cars therefore it will be in shutdown. This is in case there is an issue in the shutdown area, the ignition box will only allow the engine to go to 3000 rpm in my cars case.

If you were to set this at 9 seconds (on an 11 second car), would this be considered a downtrack rev limiter or is this a safety switch?

That's an illegal downtrack rev limiter, IMO.

Downtrack rev limiter would be my guess.

The last race I was with Mike Jeffrey at Tri-State he had not changed rear gears from Denver. He didn't think it would leg through, but 1st qualifier he went .99X under. He decided to run to the 1000 foot mark and let off. He made it 4 rounds that way and avoided a hit. It wasn't scrubbing a whole lot of ET off either.

1000' lift and coast doesn't kill near as much as some would think. It all depends on momentum and whatnot but I've found in some of my bracket cars it can be as little as .15 or as much as .30 depending on speed and weight and conditions.

Not hard to do legally...bitd 80's IHRA super stock, we had to dial either index or record and in bad air i just flat could not run the record. SOooo i would pick 1 telephone pole to run to and go to neutral and back into the index. Worked sometimes lol !

Can't speak for other combos but letting off the throttle and not hitting the brakes doesn't really kill a lot of MPH in my car.
