It'southward no hole-and-corner that on our classic Ford cars the factory passenger motorcar air cleaner assembly wasn't designed for maximum horsepower. Rather, a major consideration in the factory design was intake noise suppression. Some factory designed air cleaners came with an open element to reduce intake restriction, but this nevertheless doesn't address the issue of engine-heated air existence drawn into the carburetor. An open chemical element pattern will describe the same hot air that the manufactory enclosed unit will (just more of it) and for this story we wanted to know if getting colder air into our engine would make a difference on a pop classic small-scale-cake Ford. Our '68 Torino GT is an original F-code 302 2V-equipped vehicle with a factory style air cleaner, stock exhaust manifolds, and single exhaust; a practiced representative of a bones Ford small-block projection car. It has a C4 three-speed automated transmission and an 8-inch axle with ii.79 gears. Other than a 500 cfm Edelbrock four-barrel carb and Performer 302 intake manifold, the engine is completely stock. The cam is so mild that information technology noses over at iv,200 rpm, just the car idles in gear like a sewing machine. With the mild cam and unmarried exhaust it's difficult to hear the engine running inside the car. It's the perfect passenger car engine found in many Ford cars of the era. It was made to idle for hours in Manhattan traffic if need exist. Our auto was factory rated at 200 horsepower at the engine.

We've run plenty of stock 289 and 302 two-barrel-powered archetype Fords in the past on a chassis dynamometer and we unremarkably see between 120 and 140 horsepower at the tire, so nosotros know going in that our Torino is no screamer. However, it's an appropriate auto to brainstorm with for baseline testing because it'south a good representation of the factory ability offering found on many of our favorite classic Ford cars, including Mustangs, Falcons, Fairlanes, and more than. For purposes of testing, Spectre was interested in a more often than not stock vehicle to eliminate as many variables every bit possible. A baseline using a stock example would provide the best understanding of the starting signal that the factory gave all of us who are kickoff from scratch in the upgrading of our engine's performance.

Spectre Performance specializes in automotive fresh air induction systems. Nosotros were happy to visit Spectre and have it exam the Torino for a baseline and then come across what comeback might be realized with one of its dual snorkel cold air kits using flexible ducting. Farther, we wanted to see what arrangements the visitor offered for a solid inlet arrangement for our Torino via its build-your-own-cold-air-intake program. With the build-your-own program you can choose from hundreds of aluminum tubing lengths, angles, and diameters to custom design your own cold air induction for a one of a kind show-ready wait. The tubing tin can be welded or clamped together and Spectre offers several filter housings to ensure y'all take enough filter area for your engine. For evaluation of road horsepower Spectre has an in-house Mustang chassis dynamometer. Nosotros know from past experience and were advised by Spectre technicians that readings on a Mustang dyno run between 15 and 20 percent less than the readings seen for the aforementioned vehicle measured on a Dyno Jet. Let's see if the concept of getting cooler air into the carburetor really makes a divergence at the rear wheels.

On the Mustang chassis dyno the Torino makes its baseline pull with the factory air cleaner housing in place. The car registered 99 hp and 156 lb-ft of torque. The torque bend was flat from two,000 rpm and information technology began to drib off at three,200. As nosotros noted earlier, the cam nosed over at iv,200 rpm at correct around 100 horsepower. We would have guessed this machine at 120 hp on a Dyno Jet then information technology seems the 20 percent drop in readings, as predicted by the Spectre technicians for the Mustang dyno, was in the ballpark.

Nosotros were intrigued past the broad choice of air intake boxes bachelor at Spectre for a custom or low-profile installation. For our low-profile mock up we selected i made to fit the low hood clearance found on a Mustang.

Using the Styrofoam plugs to mock up the connections, the passenger side inlet is configured. For this scenario the battery would be relocated to the trunk.

Since hood clearance isn't an issue on our Torino nosotros decided to likewise mock up a organization using Spectre's 120-degree dual snorkel enclosure. Instead of the flexible blackness ducting, nosotros wanted to see what such an organization using the steel tubing might look like on our engine. Hither the enclosure is in place and the Styrofoam plugs added to allow for experimental connections.
