2003-2004 Ford Cobra Lysholm Twin-Screw Supercharger Install - Trade Winds
Lysholm puts over-the-top power into a stealth package for ’03-’04 Cobras
Horse Sense: “You guys never show the ’03-’04 Cobras any love in the magazine.” If we had a nickel for every time we’ve heard or read that comment—or a similar comment about another generation of ’Stangs—we all would be well on our way to having enough money to put down on ’11 GTs!
For whatever reason, there definitely has been a lengthy dry spell of sorts when it comes to talking about the factory-supercharged New Edge ’Stangs. Now before you start thinking that we simply don’t have love for the ’03-’04s, please believe us when we stress that is not the case. We certainly do dig SVT’s Terminator Mustangs—a lot. However, the bolt-on tech side of our coverage on these cars has been limited over the years, mainly because there hasn’t been much fresh gear for these ’Stangs.
As you know, we’re all about getting after it, and being your go-to magazine for details on hot, new products that the aftermarket produces for all post-’79 Mustangs. Of course, Terminators are VIP members of that collection of Ponies, and we’re happy to report that we were the first publication to work with Lysholm’s new 3.3-liter twin-screw supercharger (PN 3320020; $4,695.95) for ’03-’04 Cobras.
For this exercise, we chose to forego doing the routine evaluation that starts with a stock car as a baseline. Instead, we are evaluating the effects of Lysholm’s twin-screw unit and a set of hotter camshafts on a Cobra already modified with only the typical bolt-on pieces. On these cars, a small blower pulley, long-tube headers, and a CAI system are standard issue, but our test car also features a ported factory Eaton supercharger.
Miguel Gonzalez of Phoenix, Arizona, owns this ride. His ’03 Snake, so modified, makes 500 horses at the rear wheels. According to a few noted Mustang tuners we conferred with about the overall performance potential of factory-blown Four-Valve combinations like Miguel’s, horsepower in the low-to-mid 500s appears status quo for a hot Terminator.
Of course, sometimes we like to go beyond the status quo in these tech efforts, especially when the reward for exploring new performance territory is the proverbial big steam. Read on and follow closely. The accompanying photos and captions detail our quest to bring 700 horses to the feet of Miguel’s Cobra, through a Four-Valve camshaft upgrade and installation of Lysholm’s new 3.3-liter twin-screw supercharger performed by the skilled snake charmers at AMP Performance in Phoenix, Arizona.
