That's a seems like a little bit more of a R&D program than I want to
take on right now, George (and I'm fully aware that the difficulty may
be more perception than reality). I'm confident that I can handle a
porting job, as I've had to do a lot of metal 'sculpturing' to fit all
these tubes together. Now, it's just a question of what to cut away for
me.
I believe the same thing is said about a PP that is said about what I
think I'd like to do...rough idle and no low-end power. Am I correct
that the solution is short runners with a closely fitted throttle?
Ernest,
I still think that Jerry's approach is the correct one for us, or me anyway.
1.5" ID approx tuned ( approx 18" to 22") runner.
PL is getting very good results with the 2" OD -PP ( 27" runner carby
set-up).
The slide throttle is not sufficiently sealed ( yet) - which it must be!!
The 2" OD is realising some high HP numbers and if you need that HP you use
that sized PP.
No answer yet on idle, except that Richard Sohn is running quite nicely at
low RPM ( yes it's PP).
Lyn Hanover is confident on the performance of the PP.
The bottom line is don't discount it, it's a simple operation and I'm sure
Jerry will do it for you if you feel not confident in doing it yourself.
We will get some feed-back soon enough from PL and Jerry. Your HP numbers
WILL be up there and as for the idle and low end, it won't be any worse!
