What is the best compression ratio to run with nitrous?
A. Nitrous can be run successfully with almost any compression, however we have found that 14-1 is the highest ratio that has a reasonable “Window of Safety”. Ratios as high as 17-1 can be used, but only by elite tuners with years of experience. Using alcohol as an enrichment fuel will allow you to run higher compression ratios without fear of detonation.
