Paul,

Could you help me to rationalize for a moment?  If I want about 240 HP, I see four alternatives.  First, fast and quick is the Renesis but with new engine costs.  Second is the turbo which allows
you to normalize and keep HP up to 10,000 ft.  Third is to go with a 20B and it's extra weight cost.  Fourth is the P Port which allows use of a more  plentiful supply of used engines and associated
cost savings.  Is the conversion to P Port the type of thing the average builder can do himself or do you need to go to the local speed shop for machining?  Sorry if I'm not up to speed on this
subject, I'm just trying to catch up.  Is it a case of drilling out the round protrusion between the side ports and then filling in the side ports with epoxy or does the proposed manifold flange
kind of do that for you by blocking off the holes?  Doesn't direct entry wear away the apex seals?

Also back to the new 3D sketches, is that a newer style muffler or just a 3D rendition of your 1998 Tuned Tangential Muffler?  I can see that the ShertzBeam mounts the front of the engine but I
don't see a rear mount.

The local speed shop probably cannot handle it. We are trying to set up a distributor
that can order ten  P-port housings at a time so we can do them on an NC mill.
Any machine shop can do it and I can provide a step by step procedure.
Just takes more time. Once a machine shop does one or two they should be able
to do them in a half hour or less manually.

The new muffler is the same except Jerry Hey came up with the idea of putting
a cooling tube down the center. We at first tried an extractor type but the
gases came out the wrong end at idle.
