Good hypothesis on the radiators. Probably there is big ducting coming around the right side to the grill.
Here is more Norwood Salt Flats stuff:

...and power began pushing 1600 rear-wheel horses, which would eventually develop into 1829 horsepower measured at the crank. The car was equipped with a Sprint Car-type direct-drive sprag-clutch powertrain that necessitated that the 288 be launched by a tow vehicle pushing the Ferrari to 50-60 mph—overrunning the ratchet-type sprags—at which point the engine could be started and brought up to speed to engage the sprags. At this point the run would begin in earnest.
The “388†thus gradually evolved into a machine whose powertrain was fully capable of withstanding the torturous environment of big-power salt flats racing. As Norwood engineered out the weak links, tires, salt conditions, weather, luck, and driver skill and guts became increasingly critical.
At the car’s high water mark, Gordon drove the 511-inch Ferrari 288 to an official one-way speed of 267 mph and then placed the car in impound for the requisite return run—just in time to see the entire Speed Week event cancelled due to a flooding rain storm. The one-way 267 mph run was followed by several years of disappointing spin-mishaps and horrendous flooded-salt conditions.
The car’s bad-luck streak ended—sort of—in the summer of the new millennium when race driver Tom Stephens took over at the wheel and quickly set a new Land Speed Record run for the class at 245 mph and followed this up with an official return run at 250. Unfortunately, road-racer/drag racer Stephens was required to earn his high speed license on the fly as he raced by incrementally increasing his maximum permitted speed in increments of 50 mph from 150. And yet again, the event ended before Stephens got a chance to attempt 275 or 300 mph. At 250 mph, data logging from the on-board computer showed the car was loafing along at just 66-percent throttle opening and barely half the maximum 24 psi turbo boost.
Norwood and Stephens firmly believe the highly-modified Ferrari 308 is capable of breaking 300 mph—a supposition that may well be true considering the car’s demonstrated reserve throttle at 250mph and the fact that he car’s dyno-tested rear-wheel horsepower compares favorably with calculated maximum power required to attain 300 based on calculated aerodynamic drag and rolling resistance. At 250 mph, says Stephens, the Ferrari is rock solid, wants to be given her head.
