Default Typical stage II head flow #'s

Just want to compare flow numbers with other stage II flow numbers. I have MTI stage II's and this is what mine look like. Is this good or bad?
Int CFM Exh CFM
.500-265 .500-190
.550-280 .550-200
.600-290 .600-215

You only list the 5-6 hundred lifts?The 300-450 lift numbers are important so dont just look at the peak lifts.Here are some of the stage 2 Absolute Speed flow numbers.

Try a search, there was a thread full of flow numbers a few weeks ago.

If these are accurate flow and port volumes than we have a flow bench champion! These are the best numbers i have seen overall on this board or on my own bench. How about some track times or Dyno info?

LOL! Im sure Jay will be pleased with his newly appointed title(sound of applause in the backround).Can only give you my track times and dyno #'s.Best to date is an 11.04@121.4 with a 1.51 60'(a full second faster than your ride).Dynoed 405hp with an unlocked A4 Yank 4400 with all the usual bolt ons.Car will go a bit better in the great DA's you and I get in the northeast.This best was run at a -700 DA and there is better DA's here(-1500).A redyno is planned with the converter locked up for more accurate numbers.

Not the best quality pics sorry.These are stage 2 intake ports with the newly appointed "championship" design including the elusive 209cc port volume.

Thanks for the pics, i see how the volume is kept low in port. As for performance your car runs very well, as for mine dont you worry i am sorting out all of my short comings. This will be a very interesting race year! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
