Reply to "aluminum heads"

An aluminum head is the sign of an intellegent person.
The CHI dual plane intake looks really interseting for a Pantera. It would be interesting to see if it makes power like the Funnel Web.
I think these may be Australian horse power quotes, like the Dollar.
They don't mention at what pressures the flow numbers are obtained.
The Motorsport numbers were at 25in-mg. Everyone else seems to use 28in-mg.
With enough pressure any head will flow. If one can extrapalate the A3 to 28 then they outflow them out of the box. Who said the A3's were being run out of the box, stock? The C3's certainly aren't.
Also there aren't too many street engines (I didn't say any) that will use a .700 lift cam.
The important numbers are more likely the .500 to .600 lift numbers.
The term "support" needs to be defined and the 4v heads "supported" something like 680hp.
The highport "advantage" is line of sight. Exactly what that is worth on a street engine is contraversial at best.
The Webers don't know the difference.
I know that there are many choices now, but I suppose that my original point got lost somewhere, the point was HP/$.
