High Speed Ignition Retard

[ronnieroadster]

 With winter setting in its time for my mind to start working again. So Im wondering what would be the advantage of a high speed igntion retard. Presently I use Pertronix components on my engine I was unable to get any guidance from their Tech guy. Would anyone have any ideas?

The spark advance curve is often retarded at high rpm 'cause the cylinder cannot fully fill with mixture.

   What type of distributor setup are you using the Pertronix in?

Will it help your engine?

I converted an Accel 37000 series distributor to fit my engine.

Just have her get you a gift card at Nathan's place.

Tell her to think of it as a spa day for your engine . . .

It is a good idea to select a fuel supplier that has a racing program with helpful and intelligent tech support.  They can help you to select a good base fuel for your program.  Then, stay with that fuel during your development and racing.  Experience has shown me that the types of refinement you are doing are somewhat dependent on the characteristics of the fuel.  Switching fuels during the development process can invalidate a lot of the results and especially the spark advance curve.

As an example, my preference is gasolines that burn quickly and this allows me to use less spark advance.  The timing settings are a bit retarded for heavier fuels and I cannot get the high end power they provide.  I do not have enough spark advance when I use my curves developed for lighter fuels.

Thanks to all for your input.  My roadster powered by a little gas burning flathead Ford V-8 is oh so close to hitting 180 MPH in the standing mile. To get to the next level that 180 pass  Dyno testing including the coffee and beer might just make it happen. With winter setting in the time has come. Thanks again.

Sum, Here are some pics of Ron's car from the September ECTA meet:







REALLY good running blown flathead.....Impressive indeed!

Always loved the simple looks of the flathead -- Oh, well.

It's 20 mph over the El Mirage (gas) record.

There's nothing simple about a flathead anymore 
But I have been SLOWLY getting her up to speed so far its been five happy years of ups and downs and sometimes a few crop circles.

Maybe ceramics and other coatings if you have not done that already.  That looks like a nice setup.
