Steve,
Mark Kidd sees the same HP improvement I have seen in High compression engines. That could be due to VP reformulating the C-12 a couple of years ago. It seems to work better in higher compression engines now. I would assume there is little difference in low compression engines. Lower compression engines might even do better with the lower octane fuel.
In testing I have expereienced a 26 Hp difference in VP C-14 & Sunoco Maximal in the Splayed Valve V-6 I run. This V-6 engine is a very high RPM & high compression engine. It just likes the VP C-14, but makes even more power on VP C-25. Just try the fuel & see if it works for your combination. Each engine & engien combination could be different. I guess that is why VP lists over 50 different fuel mixtures.
