You could experiment. Since you run at 43deg. Make a run at that timing. Then make a big change, 38 deg as a example. Then make a run. Look at your split times for both runs and see if it makes a difference. If you have a better back half at 38 but it runs the front half at 43deg best, then you are onto something. You can try this before investing in something. Just a thought.

Great idea, never thought about doing that.

What I was talking about is reducing timing on the start to kill power & help with traction. Some of the more powerful cars are cutting back timing at shift points. You would need a data logger to evaluate.

I've seen improvements in heavy low compression cars, where you need a lot of timing in 1st and 2nd then pull it back in high. But that was years ago when the rules weren't as liberal.
