Al,
How is your set up different than the one Ed A. had that didn't work too well? It was also
one throttle split into two runners.

I use a 3-barrel TWM TB on my 20B with 44mm barrels. One barrel (which divides into the 2 runners) for each rotor. It seem to work quite well. As Ed mentioned, and supported by Paul Yaw¢s work, high velocity in the barrel is a good thing. Maybe you could cut the thing in half and use 2 barrels? I use the injector port in the TB for MSD (Rochester) injectors, and use
the stock primary in the housings.

I have a chance to purchase a TWM throttle body(see attch pic) at a very low price. I have a couple questions for the group.
The inlets are 42mm (appx 1.65 in.). Is this too big to the point that they would be incompatible with the injectors? I plan on using 1-1/8 and1-1/4 in runners.
Also, the bosses are sized for Bosch, Rochestor, or Lucas injectors. Does this necessarily eliminate my using the stock Renesis injectors?
This setup also would allow the use of a lightweight airbox thus simplifying the intake system from a manufacturing standpoint.
