I think this would work excellent with the Ranger 2 barrel manifold.

Interested in Fuel Injection for my 2.8. Appears the throttle body flows over 500 CFM could be too much air flow for out small V6? We also use much more lift and duration in the camshaft. Could that be a problem for the built in MAP sensor? It does look to be an interesting option, curious how this works out and what information is out there. I did watch the Holley video and online information. Applications for V8's, some 6 cylinders, nothing listed for a small V6 or even a four cylinder.

Steve, CFM in EFI is regulated so it is different than with carb. The Buick 300 Stroker V8 I helped with has a 1000cfm throttle body. The new 2 barrel is meant for 4, 6 and small V8 motors. The HP rating and CFM are really max numbers. In Port fuel injection the cam should have a 112-115 lobe center for a good idle. Most performance cams are around 110. That said, the popular E cam in Ford small blocks has 110 and idles fine. I don't think TBI is as sensitive as Port fuel injection.

Nick, I know of a Nissan V6 and a Ford 200 straight six. What cam do you have? The Jose grind will be too hot for the EFI. Have you done Mike's mod? https://photos.google.com/share/AF1...?key=ZFJIMWdqUDY4RnR0OXpiNXNCbzRoeGNuYVRRV3d3
Here is the thread on the Nissan V6:

Say what?
Just like a carburetor, airflow (CFM) with the Sniper EFI system is "regulated" by the throttle body which is controlled by a mechanical linkage to the driver's right foot; all the Sniper EFI system does is provide the correct amount of fuel for the airflow.
Just my opinion, YMMV.

Jim, the carb mount sure looks very very tall ! How does the hood close without a scoop?

Barry, Regulated is not the right word. Fuel injection is better at maintaining A/F ratio by regulating the air flow. The ratings are max airflow ratings. This article explains it better than I can:

Jim,
Granted that EFI does a better job of maintaining A/F ratio, but it does NOT do so by "regulating the air flow." It does so by controlling the amount of fuel that is supplied.
Again, airflow (CFM) with the Sniper EFI system is "regulated" by the throttle body which is controlled by a mechanical linkage to the driver's right foot.
