Torker manifold with a carb or TBI and RPM range?
Hello,
On a normally aspirated SBC350 does the RPM range of the Edelbrock Torker intake 2500-6500 still apply with a 4 barrel throttle body fuel injection system. The EFI system is MAF setup with injectors above the throttle plates. With the EFI setup I don't need a large "signal" to get Air/fuel flowing from a carb, so would the EFI setup lower the minimum torque RPM. Sorry to be so general but if all other factors such as cam, heads, exhaust being equal... would there be a difference between a 4 barrel carb and a throttle body on this type of manifold? Cheers, Zeder

You might have a bit more lower rpm response due to a more accurate way of measureing incoming air. But depending on CFM's of flow on the throttlebody vs. the carb, your intake velocity should be relatively the same. And as you are not changing runner sizes or dimensions, your power range will be pretty much the same. I dont know what the difference is in dimensions of the TBI vs. the carb. You might gain or lose a little volume depending on the height, but again, this isn't going to affect your overall powerband drastically.

Hi Ed,
Check out this picture! It is rated for 750CFM and has 4, 52 lb injectors. Looks pretty cool eh? Zeder

Here is one of the plenum cover.

Stupid question but where do the injector plug in (electrically)?

rick458,
In this picture (1) the injectors are all turned about 45 deg, the plugs are all behind each of the fuel supply hoses. Z

What are you using for a control unit and where can I get some specs on the TBI unit?
Thanks

you should be able to "MAP" it to compensate for any weaker signal by boosting or cutting the fuel pulse at any given rpm, and the Torker (misnamed by Edelbrock- as it is a mini tunnel ram by looks and rpm range) should give you a good healthy high rpm performance

It isn't missnamed. The torker is a single plane intake that has more bottom end than the normal single plane intakes. They are rated 2,500 to 6,500. Other single plane intakes can be rated to start working at 4,500+.
By no means are they like a tunnel ram. The torker has a small plenum and small runners to give it more bottom end torque.
