C-16 fuel in a stocker

hotrods1795 · 06-10-2021, 07:38 PM

Do I have to change the timing, is there any advantage in et.

Any information if appreciated.

Our Demons figure @ 11.8 to 1 and run the best on C11 even
with timing on the edge of Detonation last couple hundred feet.

What combo are you racing and how much compression?

63 Dodge Polara - Max Wedge 13.5-1

Do I need to re-jet carbs or anything with timing?

I am not a fuel chemist, but to my knowledge octane reduces detonation in higher compression engines due to slower burn time, in a stocker with lower compression C16 it would only slow it down,as it burns slower, I agree with GTX John on C11.

It works good in supercharged engines

I would check if c11 has enough octane for 13.5 to 1 compression before using it.

I use C-12 13.8 to 1. Big Block Chevrolet.
