My p ports open at 78º BTDC and close at 75º ABDC. This drawing shows how much later the ports open in comparison with the Leman P Port and how they close at nearly the same time. According to calculations made by Rolf Peiffer who helped me a lot, my little port has sufficient capacity up to 8000 rpm. After that you would want to go bigger. The exhaust port was left stock with the splitters in. . Jerry 
 
Thanks for the info, and pic Jerry.  Do you have an estimate of how much HP you expect to make at 7500 rpm?  And can you get that thing running in the next month, so it will be easier for me to decide what to do :-)
 
Cheers,
Rusty
