David,
That is still impressive.
Don't get me wrong, I still like the Brodix Heads. It just irks me that we have to send out brand new heads to pay more money to have work done to get them to flow what Brodix claims. Love their castings though.
The only way to compare anyones out of the box heads is to compare them out of the box, not after a local head porter has steppped all over them. Or after anyone has. Out of the box they way you get them is what I am talking about with the RFD CNC Heads. The other valid comparison is price for what you get. Out of the box with same price as AFR 357 or either BMF 385 or 405. Can't compare with worked heads from any mfg. Not apples to apples.
I have had examples of Brodix CNC done for Brodix according to the wishes of BRodix with BRodix Programs with both WeldTech doing the work and with Keith Craft doing the work and am disappointed in what either shows on the bench.
I have a large network of engine building friends and know a few different well recognised cylinder head porters and some of them are in tight with Brodix, and no one I have spoken with has come close to what Brodix claims the PB 1200 CNC will do. That is supposed to be the biggest, baddest head they have. It is not cheap. BRodix claims 571 cfm Intake. No one I have talked with has ever seen it test to above 530 cfm if that much. Just had a go around with a set of the -12 Brodix WeldTech CNC's. They were down appx 20-24 cfm on Intake and the exhaust was laughingly ridiculas it was so bad. The exhaust just quit gaining at .600 lift. . I sent them to Curtis and he woke them up and now they are making power. That is two very recent examples of Brodix Over pumped Flow numbers.
