High Speed Retard Question

[D. Hake 4459]

Thanks guys, that's the kind of info I need. I'm just trying to get educated on this subject as much as I can. I have heard of a few class racers that use a high speed retard and their combination picks up. I would like to hear from some of them to hear they do it. Thanks again

Now if you wanted "low gear" application instead of "high gear" application , then you might here responses with better results.

Is there something to be had in lower gears by retarding or advancing? I shift at 6500 and cross the stripe at 7000. I run 43 degrees timing and I think it may be detonating a little at high rpm.

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.

My next door neighbor is a high speed retard.
