Axles And Spool
If you take your Mustang to the track enough, you are going to break an axle sooner or later. Once you get that out of the way, you'll be able to call up Strange Engineering and order its 35-spline axle and spool package (from $528.70) for 8.8 rearends. Or you can do a pre-emptive strike and get one now. The S-series 35-spline axles are forged from SAE 1550 modified steel, and when combined with a deeper heat-treat that is designed to increase torsional strength, they're able to handle your Mustang's power and torque. The package also includes a Strange lightweight, Pro Race, chrome-moly spool; C-clip eliminators or axle bearings; and your choice of 1⁄2-inch or 5⁄8-inch studs.
Holley Performance Products' Dominator carburetor has been around since 1969 when it was developed for NASCAR. These days, the Gen 3 Ultra Dominator features an all new main body, all new calibrations, high-capacity fuel bowls, and larger sizes. The Gen 3 Ultra is available in a variety of sizes, including 950, 1,350, 1,425, and 1,475 cfm. The standard Dominator is also still available in 1,050, 1,150, and 1,250 cfm. The Gen 3 Ultra is 5⁄16-inch taller than the previous generation, which allows for larger radius air entries that have been optimized using Computational Fluid Dynamics software. The new calibration is optimized for today's larger engines and newest fuels, while the new body also features a throttle position sensor mount, and a sensor is available separately.
Steel Or Aluminum
Paul Lee, owner of McLeod Racing and NHRA funny car driver, should know a thing or 12 about clutches. McLeod's new SFI-approved, billet steel and aluminum flywheels for '10-'14 Mustang Shelby GT500s feature a stock clutch pattern and a pattern for McLeod's RXT twin-disc clutch. The steel flywheel is made from billet alloy for incredible strength, with a 1045 hardened-steel ring gear for long life. It's designed for street applications needing the added inertia only a steel flywheel can offer. The aluminum version is made from 6061-T6 for the body of the flywheel, while the friction plates are all Blanchard-ground and stress-relieved. The Blanchard grinding gives the clutch disc a much better surface to bite into. This stress-relieving procedure eliminates the potential for warpage.
ATI Performance's new Super Damper should wear a cape since it's designed for Ford's current supercar, the Shelby GT500. The 7.81-inch damper application is a direct replacement for the stock OEM unit, and features a 10-rib, 10-percent overdriven supercharger drive on the outer shell, as well as a removable OEM-size, six-rib accessory pulley. ATI's Super Damper is designed to provide balanced dampening of torsional crankshaft vibrations through all rpm ranges, and exceed SFI 18.1 Safety Certification for competition use. As with all ATI dampers, this GT500 Super Damper is fully rebuildable and tunable.
If you own a Fox or pushrod powered SN-95, no doubt you've been bitten by the bad TFI module bug. What happens is heat breaks it down, causing your Mustang to have a crank, no start issue until it cools down. Fatfoxx has the fix with its TFI relocation kit. This kit enables you to relocate the TFI module to a cooler place within the engine compartment. The standard kit is a 9-foot, 6-inch relocation kit (from $52), while the upgrade is a 12-foot kit ($85) capable of mounting your Mustang's TFI module up by the hood latch, where it'll stay cooler than Tech Editor Jones wearing a 5.0&SF bucket hat.
The boys at Power By the Hour are at it again. They know the Cobra Jet intake makes power on '11-current GTs and Bosses, so they designed and built a cold-air induction for the combination. The CAI comes with a 41⁄2-inch intake pipe with a mass air flange, PCV bung, heatshield, S&B filter, a silicone coupler, and all installation hardware. The pipe is powdercoated in a satin-black finish. The kit requires a custom tune, but Power By the Hour reports 500-plus horsepower at the wheels on modified Coyote- and Roadrunner-equipped Mustangs.
