    In a blown alky engine, any idea what kind of cfm is produced coming out the blow by tubes?

    A Moroso promod vac pump is capable of 100 cfm, and it can't keep up. I too would be curious if anyone has ever measured the blowby under power......

    I agree, a vacuum pump will never get you down into a negative number but will make it less positive.
