Packing More ProCharger Performance Part 2 - ProCharger D-1SC Supercharger

After moving some stuff around in the engine compartment, we bolted the regulator to the passenger fender apron, just below the stock mass airflow sensor location.

As you can see, the -8 braided stainless steel fuel line (left) can carry a much larger volume of fuel. The spring-lock fittings on the stock fuel lines were designed with assembly line speed in mind more than anything. We'll be using the Army/Navy-or AN fittings as they're more commonly referred to-that were included in the Aeromotive system.

Many companies offer billet-aluminum fuel rails, and Aeromotive's are some of the best. They are available separately and are also included in the PN 17105 fuel system. When you're moving major amounts of boost through the engine, stock 5-liter fuel rails just aren't going to supply the needed volume of fuel.

With our engine already making close to 600 hp at the flywheel, we knew the 42-lb-hr squirters were not going to supply the needed amount of fuel while maintaining an appropriate injector duty cycle. We called up Anderson Ford Motorsport and ordered these Siemens Deka 60-lb-hr units (MTN SD60) that retail for $499. The high-impedance injectors are direct replacements that will work with the factory computer and also feature the newer svelte pencil design.

The best way to cut braided line is with a cut-off wheel or a fresh hacksaw blade and a bench vise. Be sure to use masking tape at the cut to keep the braided line from fraying. Use some penetrating oil to lube up the line and the fittings, and twist the nut on to the fuel line until the base is fully seated. Then install the male end of the AN fitting. Aeromotive recommends a gap of no more than 0.030 inch between the two fittings, but don't overtighten them as they are aluminum.

Aeromotive's fuel pump speed controller is weatherproof, but not weathertight. We opted to mount it inside, beneath the plastic side panel where we already had great power and ground sources from our stereo installation. It is also fairly accessible should we need to make changes to the rpm activation dial.

The speed controller comes with this manual override switch that allows you to run the fuel pump wide open constantly. We mounted it in the rubber plug that provides access to the factory fuel pump inertia switch.

Our Pro-M mass air sensor served us well, but with the company now out of business, we weren't sure where to get the sensor recalibrated for the larger injectors. HP Performance's Tony Gonyon recommended we use the SCT 2800 MAF. Though designed for the newer Mustangs, a simple harness adapter and some ECM tuning will allow it to work with the EEC-IV. The meter retails for around $240.

The 90MM SCT meter measures 4 inches in diameter, and the ProCharger tubing measures 3 inches in diameter, which proved to be a problem until we called Race Part Solutions in Boynton Beach, Florida. RPS offers numerous silicone hose products including 3- to 4-inch adaptor couplings, and we had the company ship us some T-bolt clamps to make sure the hoses didn't slip off. Our step hose couplings retail for $16.95 each.

ProCharger's race bypass valve comes with a new vacuum line and a metal flange and tube to mount it permanently to the induction tubing. We took our tubing to Tracy Grimm of Speedfab in Orange Park, Florida, and had him weld the flange to the tube and paint it for us.

Not thinking things through, your author ordered the 3- to 4-inch couplings not realizing they wouldn't work with the current mass airflow sensor location between two rubber 90-degree elbows. Using quick thinking that evidently wasn't available before, your author told the HP crew that the recent intercooler relocation resulted in a long stretch of straight pipe up in the passenger's fender. After HP's Jason Combs installed the SCT MAF, we ended up with a good 10-12 inches of straight tubing before the meter, which will allow it to get a better read on the intake charge.

We mounted the race bypass valve right next to the kit's original bypass hose fitting after the supercharger. We may choose to recirculate it, but right now venting the charge to atmosphere sounds really cool.
