How to Install the CXRacing Twin Turbo - Wild Deuces
Fox Turbo Kit - Build a sly old Fox with CXRacing's twin-turbo for '86-'93 'Stangs
On the Dyno
Nothing beats doubling a Fox ‘Stang's 200 baseline horsepower, especially with a power-adder that looks as sexy as CXRacing's twin-turbo package!
Greg Montoya's EFI'd '84 coupe came to us with a fairly fresh 306 that put out 215 horses in its baseline evaluation on the chassis dyno. After installing CX's twin turbos, peak power climbed to more than 402 horsepower, with just as much torque (in lb-ft) at the rear wheels, with boost limited to only 8 psi.
"This combination can definitely make 30-40 more horsepower with a lock-up torque converter and bigger fuel injectors," said Addiction Motorsports tuner Eddie Rios. "We would see even more if the kit was installed on a Mustang with a manual transmission. So much more, we would have to consider where to limit power because the engine is based on a stock block. I like the way this turbo system is made, its price is perfect, and it definitely makes good boost."
We agree with Eddie's sentiments, especially when the overall price is taken into account. The total for a CXRacing twin-turbo kit and Holley's Dominator EFI is roughly the same price as many other Fox turbo systems—single or twins—by themselves. However, we must note, using Dominator actually is a bit of overkill—Holley's HP EFI is a perfect alternative to the big ECU, as it has many of the same features and capabilities [datalogger, boost controller], yet is priced approximately $750 cheaper because it does not control electronic transmissions and only has one wideband O2 input.
