He's got a name, but everyone knows him as Lalo. We first met him during a shoot for our L.A. Street Racers article (Aug. '08) where we photographed his '72 Ford Courier and some of his friends' cars in their club, Mexican Juice. Since then, Lalo purchased this '91 Mustang. When he bought the car, it had already been plumbed with twin turbos. Lalo replaced the previous owner's engine with his own short-block, and welder friend Ricky Arias modified some of the brackets and plumbing to make it run better. Better is, of course, an understatement, considering this Mustang now delivers 1,000 hp to the wheels with a fairly conservative tune on just 10 psi of boost. Lalo can turn it up to 18 psi (and maybe more!) with his electronic boost controller, and the power can likely jump by an additional 400 hp. We're just speculating here, though. Lalo would only cough up power numbers on the low boost tune-up. If it weren't for the turbochargers showing through the holes in the hood, you'd probably never guess this car made so much power.
At Irwindale, our local eighth-mile track, Lalo hits the 60-foot mark in 1.3 seconds and has run a best of 5.70, letting off before the finish line. 8-year-old Lolito is an even bigger fan of Fords than his father is.
Lalo recently replaced the C4 that was in the car when he bought it with a transbrake-equipped Powerglide built my Mike's Transmission. The torque converter is from Continental and has a stall rating of about 3,200. The rear is a production 8.8 with a spool.
An Aeromotive A1000 pump is mounted in the trunk-mounted fuel cell. When Lalo switches to E85, he'll need to switch his fuel lines to ones compatible with alcohol and change the fuel injectors to ones with a higher flow rating.
Under all that plumbing is a (claimed) 347ci small-block assembled by Manny Rodriguez, owner of Manny's Hardcore Performance in Fontana, California. It consists of a Dart engine block, a forged rotating assembly, a Lunati roller cam, and ported Trick Flow Twisted Wedge cylinder heads. The aftermarket block is necessary because the production stuff couldn't stand up to the amount of cylinder pressure the turbos are capable of generating. He claims it's a small motor, but note the intake spacers that belie a tall deck block.
For a while, Lalo ran with open exhaust, but now, the downpipes lead to a pair of mufflers and out the back of the car in a pair of stock-looking tailpipes. This car is stealthy-quiet.
EFI and Ignition
Lalo's small-block runs on ACCEL's DFI Gen 7 port fuel-injection system, which was tuned by Eddie Rios, owner of Addiction Motorsports in Canoga Park, California. The mild cam means that around-town driveability is still good, too. Because of the moderate compression ratio, the engine has to run on C16 race fuel—although he's thinking of switching to E85 soon. An MSD coil and distributor light the fire.
Turbochargers and Induction
Those are a pair of 72mm Turbonetics turbochargers, which are fed via a pair of custom-made headers. The intake charge is plumbed into a front-mounted air-to-air intercooler. Lalo's conservative tune-up sets the boost at 10 psi, but he can go to 18-plus by changing the settings of his MSD boost controller. Past the intercooler, air flows into a custom-built plenum that bolts to an old-school, carburetor-style mini ram intake manifold that was modified to accept fuel injectors in the intake runners. A pair of Tial wastegates and one ProCharger blow-off valve control the boost levels.
