We know who you are.
Yep! Someone who has actually flow tested, velocity probed, ported, dynod, or seen ET at track. Not someone who has offered an opinion based solely on what he is blinded by.
Kinda self serving statement when you don't have the test facts posted !
What do you need? Let's start here. Pro-Filer was designed by Darin Morgan. Heard of him? Here is a refresher course.. http://www.darinmorgan.com/dmch.html
Now you want facts? Here are two of the latest. How about Bill Simpkens who picked up an honest .25 from his reworked AFR 210's.. Right here: http://www.1320techtalk.com/viewtopi...&highlight=afr
or Kornfed who runs 11.03 with a '79 Malibu he DROVE to the track and then hit with a small shot and ran 10.08. You can find that here: http://www.1320techtalk.com/viewtopic.php?t=1520
.. Now flow data. You need it for a particular head? Velocity profile perhaps? Just ask me.
However, what does your car run?
And if yours are first with RHS seconds then I do question the facts.
When others are way ahead of RHS
Mine? Pro-Filer are as cast. You obviously know NOTHING about a port design if you don't like the RHS! It can make 600+ on an honest dyno with little work. OR 800hp fully ported! Like here: http://www.1320techtalk.com/viewtopic.php?t=1456
Let's keep comparing something I've ported vs a AFR because in the real World they are far from as-cast!
Flow numbers and true HP & torque numbers are 2 very differant things.
Hey we finally agree! And flow is OVERRATED!! Again, what does your car run and at what weight?
And lastly, JUST LIKE YOU, I offered my OPINION! What gives you the right to question my motives? What gives you the right to question Pro-Filer when you have never even seen them? I've never got on this site and said buy my heads! If I have, please show me. AFR is a good head, sure, STREET HEAD! However, there are many more players out there. Take your blinders off. BUY WHAT YOU WANT! It's your money..
