Greetings,
OK, I have my dunce cap on,
since I ignored the previous intake lectures.
Say you have TB that
has two butterflies, and each butterfly feeds one rotor (primary and
secondary). There is no connection between the
two rotors. Is the length of the intake runner important for
full throttle operations?
I assume it is, and recall
that racing manifolds can have a short, almost non-existent runner. I
believe Ed used one of these originally, and got less than exceptional
performance. If I recall correctly, it was decided that it would have been
fine at racing RPM, but not 5500 or so, where he wanted to run.
Assuming it's important, is
there a rule of thumb for the length of the runner for a particular rpm
range? I'm wondering if I can keep my TB in the (turbo free) left cheek,
and get enough runner length to optimize operation at about 7500
rpm. Probably a silly idea, but my only other option is still trying to
sneak it under the cowl to the right cheek.
Thanks,
Rusty (I can already hear
Ed screaming <g>)
