XPI TimingLock - Tech Inspection
http://images.mustang50magazine.com/techarticles/m5lp_0804_02_z+ford_mustang+XPI_TimingLock+.jpgPer formance-enhancing bolt-on parts are the products we tend to focus on in many of our Tech Inspection reports. We acknowledge that making more power is largely considered the ultimate goal for most hard-core Mustang heads, and that's one of the main reasons we like to showcase parts and systems that alter a 'Stang's attitude
Every once in a while, though, it's important to shine some of the spotlight that we dedicate to horsepower on the pieces that support blowers, turbos, and nitrous systems.
We learned of eXtreme Performance & Innovation's new TimingLock through one of our regular journeys on the Web, hunting around for new Mustang-specific products that aren't on our radar. The TimingLock is for '88-'95 Mustangs with TFI-IV/ SPOUT distributors.
As many of you know, advancing (increasing) timing is a prerequisite for pouring on the oats in a 'Stang's engine. Unless you're using a standalone or piggyback engine management system, manually turning the distributor counterclockwise is the only other method of adding timing, or more specifically, locking out timing at an optimum advance setting for a particular combination. According to XPI's owner, Eric Hughes, the TimingLock ($149) makes this type of adjustment easy, as it allows enthusiasts to advance/lock-out timing on the fly by pressing a few buttons to achieve a desired setting. The other alternative is to deal with constant locked-out timing and the low-rpm nuances that go along with it, including surging idle, poor driveability, and low fuel mileage.
This type of set-it-and-forget-it flexibility is especially beneficial to those who use turbos, blowers, or nitrous and wish to run stock timing for normal driving, and then step up to pinpoint, locked-out timing whenever the wick is turned up. For drag racers, the unit features a built-in, two-step rev limiter (blue wire) that requires a separate switch for activation. We didn't connect it, but it's cool nonetheless.
We gave the TimingLock a try on a '93 'Stang that sports Vortech's S-Trim supercharger on the 302ci bullet underhood, and we put the install in the capable hands of B&D Racing's lead tech, Mason "Mase" Rowland. The operation requires simple handtools, such as sockets, a ratchet, a wire cutter/crimping tool, "tap" connectors, a toggle-type switch, and wire. The job can be performed in your driveway in about 45 minutes.
With base timing dialed at 10 degrees advanced, Mase hit the road after installing XPI's TimingLock to evaluate seat-of-the-pants performance, first with the unit turned off, and then on. "The car is smooth with stock timing, and it seems easier to cruise around than when the distributor is full-time locked at 14 degrees," says Mase. "When I activated the TimingLock and gave it a few blasts, the car performed exactly as it did when timing was manually locked. There was no pinging or other abnormalities. It just basically took off, like it usually does, and all I had to do was press a few buttons to make it happen."
