So I thought I might start a topic on OGUN the clevo. Probably a little out of order but here he is being born. Hope you enjoy.  
 
 

Made room around the guide area as usual but nothing else really. Beyond popular belief theres no need to do anything special on any exhuast really. Needs to be a epically big cfm flowing head before you worry about big numbers on a exhuast.

The flow bench just tests at a constant pressure. 28" is the industry standard. It can't  account for boost as it relies on suction to get the cfm reading. 
Porting for boost will always draw different opinions, as with most aspects of engine building.  It is generally accepted that if you can make the port flow more, then it will make boost quicker and therefor make more power at the same boost pressure of an unported engine. 
Ive spoken with Ray Hall at length about boost and porting for boost and he simply said - do what you are doing for aspo.  Ray has been playing with boost for a damn long time. If your interested hit up his face book page and look at the Audi he is building g himself now. He is a champion bloke. Doesn't suffer fools.  

Nah thankyou. Entertaining as always. In reality the flow figures mean squat as you'll be blowing an atmosphere or better in there anyway.  Can't wait to see the track numbers. Should be good. Hope you have the cage designed. 

Nice. We will fill in the blanks ourselves. 

So are you going to post figures of this one? 

So 240-250 peak flow?  All sounds good and the boost will make those low lift gains come on really strong. Good stuff.
