Bolt-On Fuel Injection With Cutting-Edge Airflow Technology


FT. LAUDERDALE, FL – Adding a finely tuned high-power electronic fuel injection system to your muscle car, racecar, or G-machine has never been easier. The airflow experts at Wilson Manifolds are proud to announce their latest innovation, the V-FORCE EFI throttle body. Unlike most fuel injection conversions, which require dozens of parts including a new intake manifold, the V-Force system is an all-inclusive fuel injection solution that integrates cutting edge Wilson airflow technology and turnkey EFI reliability in one slick-looking package.

Wilson Manifolds' engineers developed the V-Force high-flow throttle body using the latest computer modeling software to produce a design that yields maximum flow per square inch of cross-sectional area. Eight fuel injector bosses (injectors ranging from 30-lb/hr to 160-lb/hr available separately) are designed to introduce fuel into the air stream for maximum atomization, and custom Wilson billet fuel rails and stanchions make installation a snap. The V-Force EFI features a standard 4150-style flange, so it will work on all popular 4-barrel intake manifolds. Best of all, thanks to the unique eight-injector design, the V-Force throttle body is compatible with most of the popular aftermarket ECUs. Simply bolt the V-Force body on a standard four-barrel intake, add a coolant temperature sensor, throttle position sensor and O2 sensor (all available from Wilson), and hook up an ECU, and you're ready to make horsepower. The V-Force system is designed to work on small block and big block V8s, as well as import and European applications.



The V-Force billet 6061-T6 aluminum body flows 1130cfm and incorporates four tapered and radiused throttle bores and a precisely machined progressive linkage for smooth throttle operation. Inward opening throttle blades eliminate part throttle directional influence by the blades that can cause poor air distribution. Throttle shafts are machined to Combining the V-Force EFI with a Wilson Manifolds tapered spacer can add up to 110 CFM.

price to be $698 without injectors

For those that want to leave the dark ages, but still can't face getting rid of the carb itself.

No for those who need more airflow than a stock EFI throttle body can flow

Not impressed (aside from the funky looks).

Fuel injection offers several advantages over basic computer control, manifold dersign being one of them.  The manifold is only required to flow air, not an air and fuel mix so the design dosn't need to deal with issues such as pooling etc.  Basically you get a much more efficient manifold as all you have to deal with is air flow.  As an aside you then fire the injector at the back face of the valve, if you get the distance just right, lovely atomisation.

The problem is the intake manifold really.
You read all about carb and manifold combos that can flow 750cfm, which sound way better than the cfm that a typical fuel injection combo flows, but the fi one is moving just air, the numbers are not comparable.

As you need sensors, an ecu, high pressure in tank fuel pump and all sorts with that thing, I fail to see the big deal of just adding the right intake manifold in the first place and doing the job right.

Thats fine for stock production but when you get into engines that were never designed or make massive power those systems dont work. Thats why they produce throttle bodies like above

In what way don't they work?

(I should probably know better than to ask...)

thats ok cause im not gonna get in a pissing contest have said my piece
