Default "help" McCulloch Mac 2181 (PRO MAC) "28cc"

Hey there all,

I’m going to have a go at building a tuned pipe for my Pro Mac 28CC using the following internet site as guidance:

[link=http://www.mh-aerotools.de/airfoils/javapipe_en.htm]DIY TUNE PIPE[/link]
(Need JAVA if you want look at it)

Well I know the CC’s (28) of my PRO MAC but yeah that’s it, according to the program I need:

1. Velocity of Rotation (RPM)
2. Exhaust Port Angle (o)
3. Transfer Port Angle (o)
4. Exhaust Port Area (mm2)
5. Exhaust Gas Temperature (oC)

If anyone knows the data already or can help me find it by explaining or maybe even finding an internet site that would be so awesome !!! The hardest part is the exhaust head attachment as on this particular model they are just clamped on using some dodgy spring system that takes your eyes out when trying to take it off and replacing.

THANKS ALLOT,
milne
