Has anyone experimented with this?
The theory goes:
A long, narrow inlet tact will create more torque at low RPMs but at high RPMs will restrict flow, impeding power.
A short, fat inlet tract with a large throttle body will increase top end power but low down torque will suffer.
So surely, if you stuck a dual length inlet tract onto a large throttle body, with some kind of internal flap directing the flow between the two, based on load/rpm, you'd be onto a winner?
I don't know how viable it is but if you took a vacuum feed off the inlet manifold and hooked it up to one of those cold start flaps*, it should work, right?
*had one on a 106 once, on cold start the flap would open up to a pipe over the exhaust manifold, blocking off the cold intake.
