Hi guys,

Found this nifty little exhaust pipe desing tool online. Plug in a few varables and it spits out the design.

http://www.mh-aerotools.de/airfoils/javapipe_main_en.htm

So lets pool our knowlege and make a pipe.

What we need to know:
RPM, Exhaust Port angle, Transfer Port Angle, Exhaust Port Area, Exhaust Gas Temp.

If you know any of these variables, post it here. Once I get all the info, Ill weld up a pipe and test it.

RPM would be 5500
Fuel type is gasoline.
Exhaust Port is 35mm (diameter) so I'm guessing the exhaust port area is 964 (not sure on this)
