How much compression increase when spraying methanol? - 11/07/21 05:34 PM
I'm building a fresh 493" EFI'd pump gas RB motor that had 10.2 to one compression. I had been running the mechanical DC carbs, but am switching to a Holley HP unit with coil-on-plug and a Wilson ported Victor single plane with their throttle body.
Does anyone know how much I can bump up the compression using pump gas while injecting straight methanol controlled by the Holley computer? I've heard I can run at least 11 to 1, but have never used methanol injection before.
