Heads up racing, killing time

May try some heads up and index racing out in FL. May run 5.00 and 6.00 index, just need to figure out how to kill 8 to 9 tenths between rounds.

For 6.0 shift the 1-2 0.32 after TB release and then pull 6-10* timing for 6.5 seconds.

I assume (from previous post) you have MSD 7330 (newer 7al3).

If you have a delay box with multiple timers you could set this up on a toggle switch to go from one to the other, or if it has two mode settings it could possibly be used this way.

Yea I have the new 7AL 3. I shift with the box on RPM. Pulling that timing wont cause any issues with motor?

If using a crank trigger and having the distributor phased correctly removing 10* won’t damage your engine. If using the trigger from a locked distributor, removing 10* should not cause any problems.

You need to have a delay box with multiple timers to do the shift and timing retard to see what effect it has on your ET. What delay box model do you have ??

Personally I don’t think you can reduce the ET by .9 in the 1/8 mile but it hurts nothing and is easy to try.

True dat. But it makes the lowly throttle stop racer feel all warm and fuzzy. Images of Glidden dance in their heads!

The index racing is a blast. I run regular bracket racing and then also run the SHRA NE2 class which is a 5.00 Index with .400 ,370?) Pro tree. Completely different challenge to make run the number at different tracks, weather and altitudes. We have raced at Density Altitude of under 500 feet of air to over 7550 feet of air and we are not allowed delay boxes or throttle stops. Lots of fun and very challenging.

I was assuming no TS allowed.

There is another way to do this that I’ve used when running a 10.20 class with no TS allowed. My method was not well received and eventually they instituted a rule that band it. But I liked it and it worked well.
