Just a quick update. MFI to EFI bungs are in and will be using the carbs will just be throttle bodies and port injection.
Have at those questions  |

Vacuum fittings selected. I will have to drill and tap each manifold to get a good signal for the MAP sensor

QUOTE(mb911 @ Jan 13 2023, 04:14 PM)  Vacuum fittings selected. I will have to drill and tap each manifold to get a good signal for the MAP sensor Here is what I did for vacuum fittings on the mag throttle bodies. The little brass tube at an angle on the far left throat next to the idle air bypass screw is the single stock vac port. I machined the middle and right throats for insertion of brass tubes and then used JB Weld to form a boss to seal them that mimics the stock boss. I’ll run the six vac lines to an accumulator to smooth the vac signal. I hope to run a TPS driven alpha N and MAP signal to the Motec. Hoping to get throttle response as good or better than MFI.  You can see the injector ports on this engine I am using for mock up have been sealed with JB Weld or similar by the PO. I think the ports on my actual engine are sealed with the screw in plugs you mentioned. |
