Tuning the now charge-cooled 393 was done in-house at the JBA Performance Center using an SCT four-bank chip. A conservative tune that ignored peak power and concentrated on cold start and normal speed driveability was installed, the idea being to rack around 1,000 break-in miles before strapping down on JBA's chassis dyno for a final power-building tuning session.
The break-in dyno tune was the latest word at press time as the car hadn't built up the needed mileage for its final tuning session. Still, clearly the owner has a torque monster on his hands. Running conservative air/fuel ratios in the 10:1 to 11:1 range and slightly stunted ignition timing, the blown 351 stroker laid down 499.8 rwhp at 4,400 rpm and 655 lb-ft at 3,300 rpm. In fact, there was over 600 lb-ft of torque from 2,700 to 4,300 rpm.
When tuned past safe mode, we guess this one will put down 525 hp and 665 lb-ft of torque at the tire. That ought to be enough to keep the veteran Saleen in the hunt. As for the rest of us, we've now seen what it takes to add charge cooling to a stroker Windsor.
Nice InsideEngine building is one of many capabilities the JBA Performance Center offers, and when it came time to build the Windsor stroker in our subject car, they used a quality set of hot-rod parts. In the bottom end, a SCAT 4340-forged-steel crank, SCAT H-beam rods, JE forged pistons, Clevite race bearings, and Total Seal piston rings went into the short-block. Upstairs, a pair of 205cc Air Flow Research cylinder heads set the torquey tone, backed by a Professional Products intake, an Edelbrock phenolic spacer, a 75mm Professional Products throttle body, and a 90mm Lightning mass air meter. Given the mid-600 lb-ft of torque at the tire from this 393ci combination, the medium-sized 205cc Air Flow Research heads seem a smart choice.
 Discharge hoses don't come...  Discharge hoses don't come much shorter than this. JBA Performance Center sourced this important molded-silicone connector from Hose Techniques. It's not part of the Vortech charge cooler kit. |  With the traditional locations...  With the traditional locations sewn up, JBA built its own water reservoir for the charge cooling system. Tall, narrow, and mounted between the engine and the radiator, the 13-inch-tall tank is mainly unseen. Its screw top is as wide as possible to accept ice, but its fine threads are maddeningly difficult to get started. |  Centrifugal blowers demand...  Centrifugal blowers demand bypass valves to vent boost pressure when the throttle is suddenly closed. JBA prefers two bypass valves to vent sufficient air charge, but there was only room for one in this crowded installation. So far, it seems to be working. |

JBA used a raised cowl hood and had to notch it slightly as well. |  About the only thing visible...
