Reply to "351c EFI intake manifold"

Doug,

the marque with the prancing donkey and the marque that's full of bull don't install IR FI on their street cars, they install one throttle body per bank of cylinders, 2 in total, not 8 or 12. A runner for each cylinder connects to a plenum serving one bank of cylinders, and there is one throttle body feeding that plenum.

I'm a big proponent for fuel injection conversion, but not of the IR type. I can't argue IR doesn't look good, it does, but it is unneccessarily complicated and expensive, definitely not for everyone. I have my personal doubts that it makes any additional horsepower for a motor with a redline of 6500 rpm.

Here in the Pantera hobby there is a mystique about FI installations that they are only for the knowledgable insiders. But over in the Mustang hobby, or among the various GM groups like the Camaro guys, retro-fitting FI is no big deal, its done everyday, even folks with limited technical ability install them. The folks outside of the Pantera hobby have 4 advantages, there is plenty of information available to assist them, they are retro-fitting injection onto motors that have been fitted with FI by the manufacturer, there is nobody telling them it is too complicated, and they are not installing independent runner systems. One throttle body is enough, keep it simple.

I agree that it would be nice to have a FI manifold available so that an owner doesn't have to roll his own, Trick Flow actually announced the development of one two years ago (for 2V heads) but that project is on the back burner at the company right now.

At this point in time, a Pantera owner wanting to convert to single throttle body FI, but not wanting to modify a 351W intake, is left with installing one of the throttle body injection systems, or the systems employing a modified single plane intake.
