RE: [T3] A bit more...balance.


Ahhhrg!...I forgot to add that, thanks!  Yeah, that's why the intakes are
tuned like an exhaust header, so the shock wave will help feed the other
cylinder.  Thanks for making that more obvious, I knew I was missing
something :)

I should also point out that tuning an exhaust header and an intake
generally help the engine produce improved power at a certain rpm.  So there
is, again, compromise, when tuning the system (making a computerized
variable system is beyond the scope of our list).  Making such computations
requires simple algebra or Jim Adney with his slide ruler next to you ;)
