One port at a time. I only posted the average for simplicity. They offer the scatter numbers on their site.
Rusty, They flow better on hughes bench, they performed better in the Mopar Muscle test. Use whatever you want. I'll take floww numbers that jive with someone elses dyno numbers all day.
I myself have seen the perf RPm and the Victor beat the SP indy dual plane intake on a dyno. This jives with the issues hughes found.
Anyone selling parts or services has money to be made. However, if the money you make comes from max performance, you aren't going to lie about which intake is better.
Even further on this note, I've talked to 4 different head porters thus far in my journey towards getting my heads and intake ported. Evey one of them recomended either keeping my Perf RPm or swapping it out for a Victor. Are ALL OF THESE GUYS STUPID OR GETTING GREASED?
