When the '05 Mustangs hit the scene, we thought they were the greatest thing since sliced bread. However, when the '11 Mustang GT hit the streets, the '05s were uncut loaves. Still bread, but now we had to do work to let 'em eat.
With the ultimate kick in the teeth to '05-'10 Mustang owners, the '11 Mustang GT brought an extra 107 hp to the table from the factory. With just a little tuning and a few bolt-ons, the Coyote-powered GTs were making in excess of 400 hp at the wheels. What's an '05-'10 GT owner to do?
Comparing an '05-'10 GT to an '11-'12 Coyote-powered GT just isn't fair. The '05-'10 Mustang GT is a great car, but the power department isn't up to par. However, we're here to help for your next trip down the strip.
To level the playing field, there are several options. The addition of a supercharger or turbo will yield rwhp numbers in the 460 to 470 range. Anything more than that and the engine's bottom end is living on borrowed time. Plus, an '11-'12 GT with a blower or turbo is going to make upward of 550 rwhp so an '05-'10 GT is still behind. You could always swap in a Coyote engine and Ford Racing Performance Parts Control Pack. You could even just go buy an '11-'12 Mustang GT and let someone else fool with the Three-Valve.
However, in these times, many people aren't able to plunk down big money on a new GT, or even on a power adder. So what's left? The next best idea is to do a heads, cam, and intake swap. Of the choices, the H/C/I swap is the cheapest route.
In the case of this installation exercise, we have an '05 Saleen S281 convertible. Owner Joe Downs was looking for performance upgrades to make it possible for him to keep up with '11-'12 Mustang GTs. He wanted a fair fight. His Saleen is flawless, and he really didn't want to part with it—he just needed more power to retain his street cred.
Before we did the install at Pro-Fab Performance just north of Tampa I took Joe's Saleen for a ride. Having driven several '11-'12 GTs, and my own daily driven '94 Cobra with a Coyote transplant, I really thought something was wrong with Joe's car at first. It had no "pull" whatsoever. It didn't want to get with the program it seemed, but I was driving the car in a spirited manner, it just didn't have the spirit under the hood to inspire.
What Joe did was get with Matt Larue from Pro-Fab to formulate a plan on remedying that lack of spirit. Having experience with this situation, Matt and Joe called Blow-By Racing for a pair of its Stage III CNC'd Three-Valve heads and Stage II cams. To which Joe added a FRPP Three-Valve performance intake. Though larger injectors aren't needed, to make sure the engine wouldn't starve for fuel, Joe threw in fuel rails. For good measure, Joe is also having Matt install a Hurst shifter, FRPP 4.10 gears, and BMR Suspension's tubular K-member, and rear control arms.
That's a lot of work, so let's get started.
