Ford Racing 4.6L Aluminator Crate Engine - Alumination Determination

The blow shield midplate was modified by cutting off the top two bolts, in order to fit the aluminum block.

A Centerforce DFX clutch was used to transfer the power to the Tremec transmission in this supercharged Mustang.

The new engine package was lubricated using Pennzoil 5W-30 oil.

Real Speed Automotive hooked us up with a set of its 60-pound fuel injectors. These injectors retail for $395. If you need adapters for the old-style injector harness, Real Speed offers a set of eight for $449 (with the adapters).

On the left is the new Real Speed Automotive 60-pound injector, commonly referred to as an EV6-style fuel injector. It's long and skinny. The short and fat one (right) is a 42-pound injector, and this style injector is called an EV1. The EV6 injectors are the newer style, while older cars run the EV1.

Everything is buttoned up and ready to run. Note: The TFS alternator replacement bracket has provisions to space out the alternator properly when switching to the thicker eight-rib pulley configuration.

Here are the stock short-block horsepower numbers.

By just adding the Aluminator short-block and a set of AFM F-72 cams on top of the ported Fox Lake heads, this engine responded with 499 rwhp and 446 rwtq. The engine made the same 11 psi at peak rpm (6,100 rpm) as it did with the stock bottom end and AFM F-42 cams.

Due to deadlines, we were only able to run the D1SC blower with a 3.50-inch pulley. The blower made 14 psi at the 6,700 rpm redline, and final output was a darn impressive 604 rwhp and 492 rwtq.
