Your Right Sorry I should've been a little more clear. operating on
about 3hrs of sleep a night right now bare with me.
First the engine is street ported, and I took the rotary valve out
last night. I had left it in the first time I put the motor together
and I did the build up inside of it with the epoxy putty well when
I took the motor apart to have it powder coated it baked the epoxy
in the valve and shrank a bit (the epoxy that is) so as I was cleany
up the build up to put new epoxy in the valve, I watched Bruce's
video again and when he did his build up in the video it makes no
mention of leaving that valve in. Bruce just does the epoxy build
up inside the port, so I took it out all together. But what I'm
trying to figure out is why did I leave it in, in the first place?
was there something going around that said to leave it in the port?

Not that I know of. This is probably a good thing to
do to a six port for aircraft use.

What is your definition of "probably"? And can you clarify what "this" is, ?
I'm not sure what I'm looking at, but whatever it is, I don't think
I have seen it before.
Tony
It is a six port that has been ported out to a four port.
Probably has to do with the intake manifold you make.
If the pipes are not the right length and diameter
than you will probably not get the HP you expect :)
I can't say what the right length and diameter is for 6500
RPM 2.17:1 psru or 7500 RPM for a 2.85:1 psru.
It needs to be developed on a dyno. Sorry.
Refresh me on your engine. What year is it? What do you intend
to use for an intake manifold? What psru ratio are you using?
