Typical stage II head flow #'s
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

Re: Typical stage II head flow #'s 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.

The exhuast is flowed without a pipe.Intake port volume is 209cc's.

Re: Typical stage II head flow #'s 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?
Re: Typical stage II head flow #'s 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.

Re: Typical stage II head flow #'s 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" />
