And while I want to see my product successful it needs to as evenly matched as possible to the more established combinations. Since there is no way to know the absolute performance potential of any factory produced engine prior to someone spending the time and money to build it and put it through its paces. So the options are to either change the name of the current category to Nostalgia Super Stock and do not allow any new combinations or try to constructively support NHRA in keeping the playing field as level as possible.

now that the cat is out of the bag, what is the HP potential or airflow potential of that blower? answer the question honestly, or any further input to this thread will be meritless. I know what other blowers of similar displacement are capable of, even on the 4.6 4v motors. NHRA has admitted that they have no specifications on this blower (rotor specs, case clearances, pulley sizes, boost@the rated 425 hp, max boost and or airflow of the unit, etc). All of this info will determine the potential of that combo.

I once spoke with a very well regarded engine builder who specialized in turbo motors. I asked him what the ideal comb was for xx turbo. His repsonse was that it doesn't really matter, the turbo makes the power. I think that holds alot of merit with supercharged motors as well ( i understand that the positive diplacement blowers are somewhat more affected by upstream restrictions.
