Cams choice, Low CR vs VE%
Just curious, how did you specifically implement this process in your car?
You start at the carb. That’s where you get the process going.
The next big thing is the tune. Most guys run way too much fuel through the engine. More fuel equals less vaporization.
Booster gain is a big deal.
Then if you think you have fuel issues you have to deal with the intake manifold, reducing corners, getting the correct taper for the runner (if you can...you do what you can) eliminating section changes (most of these are reasons NOT to use any dual plane intake manifold) and maybe even surface finish on the runners.
As shrinker so aptly pointed out...pump gas is near impossible to get complete vaporization. It is what it is. That’s why when reading a plug you need to know what the fuel is and how to read it.
I’m not a fan of buying race fuel on sale and changing brands. You can have 5 different brands of race fuel, all the same octane and they all may read differently.
In fact, what shrinker wrote on plug reading should be a sticky in the race forum.
Yeah Shrinker passed too soon. When I first got into carbs and tuning I asked him about improving the Holley design and what to do and his response was "Why? By the time you fix the Holley you'll have a Carter". I didn't understand what he was talking about at the time but after a lot of questions and reading i caught onto what he was on about.
Have you ever looked into his Laminar Flow Design carb?
I have not. Do you have a link? I know when the other forum went down it was a big loss.
