Plenum vs. Throttle bodies
Discussion
I'm planning on converting my Pinto powered Tiger to fuel injection this winter and am trying to decide between the two options. I'll be using Megasquirt to control the injectors.
Which setup is best for drivability? I use the car mainly on the road with the odd trackday here and there. Also, some fuel economy will be welcomed at the twin 45 Webers I'm currently using aren't exactly fuel efficient :D
If I go plenum, I will have to either make a custom one up or modify a Sierra one, as space is tight under the bonnet.
Bike throttle bodies have the problem of mating them to the engine either via a DCOE manifold or the Sierra injection one (advantage there is I can use the existing injector locations).
Any thoughts folks? :)

At the moment I'm running twin Weber 45s, which I guess are very similar to throttle bodies. I've not noticed any lack of torque I must say. In fact the rolling road result shows I have more torque than bhp, although I have since changed the camshaft.
The only reason I'm considering a plenum is because I'm thinking of fitting a supercharger. I believe this can't be done with throttle bodies as the throttle butterfly should be before the supercharger, not after it?
