AFM High Volume Power Pipe

Anderson Ford Motorsport makes...        read full caption Anderson Ford Motorsport makes Power Pipes for a variety of Mustang applications, including naturally aspirated machines. Anderson’s Power Pipe relocates the filter and mass air meter in the fenderwell, so instead of leaving your filter under the hood gulping in hot engine air, with a Power Pipe you’ll be feeding your engine nice cool air. Prices begin at $185 for ’86-’93 naturally aspirated Power Pipes, with an option of HPC-coating for an extra $50. Add $56 for the larger Power Stack filter.

Pro-M’s 80mm mass air...        read full caption Pro-M’s 80mm mass air meter is most popular with racers and owners of modified street Mustangs. It greatly improved our driveability, which in turn made a serious impact on power output. This meter sells for $338.

This hole in the inner fenderwell...        read full caption This hole in the inner fenderwell must be opened up to accommodate the High Volume Power Pipe. Since the pipe is 4 inches in diameter, the hole needs to be a shade larger.

Once the pipe is in place,...        read full caption Once the pipe is in place, the wiring harness must be lengthened so it can reach the mass air meter now that it will be residing in the fenderwell. The directions mention the possibility of cutting and splicing, but Jake LaMotta simply unwraps our factory harness and routes it out to the meter.

With the High Volume Power...        read full caption With the High Volume Power Pipe installed, it frees up a lot of room on the passenger side of the engine compartment for the likes of an ignition box. The mass air meter sits just outside the factory air box hole.

Ever since we installed Holley's SysteMAX II package on our '93 LX, we've been struggling to get it to run right. It seemed to run best at 3/4 throttle, but as soon as we put it to the floor, the coughing would begin.

We decided to give Pro-M's 80mm mass air meter a shot. While we were trying the new meter, we decided to team it up with an Anderson Ford Motorsport High Volume Power Pipe ($232.66) for '86-'93 naturally aspirated Mustangs. Hopefully, between the meter and the pipe we would not only gain better driveability, but also a substantial boost in horsepower.

For once, we were correct in our assumption. With the stock air intake connected to a Pro-M 75mm Bullet, our coupe turned in a horrible 236 hp at the rear wheels. With an air/fuel ratio of 14:1, we knew something was amiss. After changing over to the High Volume Power Pipe and 80mm Pro-M, horsepower jumped to 269, with a much-improved 13:2 air/fuel ratio. Just for grins we installed the 75mm in place of the 80mm unit. In this form, our coupe turned in 252 hp at the wheels. These numbers were recorded in unusually cool Florida weather (mid 50s), so your results may vary. Furthermore, our 75mm Bullet probably had a bum calibration or damaged sensor, and by adding the 80mm our state of tune is greatly improved. Anderson Ford Motorsport reports a 10-18hp increase by adding just the pipe itself without the meter and another 2-3 hp with the Power Stack filter.

To help us with this install, we contacted LaMotta Performance. Jake LaMotta installed the Power Pipe and meter with little hassle, save for the passenger-side fender splash shield that didn't want to go back on. With a little persuasion it did. Now our '93 runs stronger than ever.
