Reply to "351c EFI intake manifold"

Nice kitty Mr.Pence.

One last point of signifigance here is that with a EFI FI system, a very radical camshaft with a lot of overlap can be run on the street.
That would not be so with the EFI and a common plenum.

Plenum reverb in theory no longer exists with IR EFI.
Since no cylinder is 100% efficient, there has got to be some unburned mixture or oil contamanent blown back into the intake system.
Maybe that's even a plus. Maybe it will lubricate the valve stems?
The question that was possed in another discussion is how signifigant is it?
It certainly won't have the reverse venturi flow problem that the IDA's do.

Probably the answer is that it will need to be determined by experimentation but I wouldn't be too surprized to find NASCAR or Prostock type camed engines idleing like a pusseycat with a IR EFI. It is certainly now in the relhm of possibilaties and evn very highly likey.

IR EFI opens up an entirely new era to radical street machines.
