The F40LM seen here, is far more exclusive than even a normal F40: it is one of the genuine, ultra rare Le Mans (LM) versions originally built for Ferrari’s most favoured clients.
While Ferrari never originally intended for the F40 to go racing, a number of individuals with the wherewithal to put the car on the track quickly realized the F40’s racing potential. Daniel Marin, of Charles Pozzi Sa, successfully lobbied Ferrari to authorize Michelotto to produce a series of racing examples that adhered to IMSa rules, giving the world’s fastest production car a chance to earn its keep on the race track.
This limited-production Ferrari, dubbed the F40 LM, for Le Mans, would be much more radical, exclusive, and exciting than the already intense F40 in every way. The chassis had work done to it and it was fitted with a way more aggressive body kit as well as race inspired front and rear wings.
Brakes, suspension and gearbox as well as wider wheels and tires were all part of the LM treatment. If you can believe they even found a way to strip even more out of the already stripped our F40 interior. In a further effort to save weight, the F40’s distinctive flip-up headlights were replaced with fixed lamps behind Lexan covers. The Ferrari F40 LM weighed just 2,314 pounds.
While similar to its road-going brethren, the F40 LM employs extensive revisions to the original’s aerodynamics.
To start, the front intake is deeper, while the carbon fiber front splitter is extended. The hood is modified with a new NaCa duct (a type of low-drag air inlet originally used on aircraft), which is placed above the front-facing Ferrari badge, plus there are large cutouts in the hood to improve heat dissipation. Weight is kept off the nose thanks to fixed headlight housings covered in Lexan, which replace the standard F40’s pop-up units.
More plastic replaces the side windows, while additional NaCa vents are placed just ahead of the rear wheels. The side-view mirrors are adjusted for better aero, and the lightweight alloy wheels come from OZ racing in a unique design measured at 17 inches in diameter.
In back, we once again find a trio of exhaust pipes, but the rear wing is significantly more aggressive, featuring a center section that can be adjusted from inside the cockpit.
In road-going trim, the F40 uses a longitudinal, rear-mid-mounted, 90-degree 2.9-liter twin-turbo V-8, with double overhead cams per cylinder bank, and four valves per cylinder. Output is rated at 478 horsepower at 7,000 rpm and 424 pound-feet of torque at 4,000 rpm. Properly applied at the rear wheels, this powerplant produces a frenetic, insane level of performance – but it’s nothing compared to the LM.
To prepare the racing F40 for on-track domination, the Tipo F120 a V-8 engine was drastically altered, so much so it received a new designation – Tipo F120 B.
Displacement remains static at 2,936 cc’s, but the twin IHI turbos were updated to produce as much as 2.6 bar (37.7 psi) of boost, rather than the standard F40’s 1.1 bar (16 psi).
Complementing this are larger intercoolers from Behr, as well as new cams. The compression ratio was uprated from 7.8:1 to 8.0:1, while the engine management was swapped in favor of Weber Marelli IaW 072 with dual fuel injectors per cylinder.
all that amounts to 720 horsepower at 7,500 rpm, but without the restrictors, output would go up to 760 horsepower. Some reports indicate figures as high as 900 horsepower.
To handle all that, the LM got an upgraded high-performance five-speed manual gearbox, which ditched the synchromesh and employed a triple-plate hydraulic clutch.
as for acceleration, the 0-to-60 mph sprint takes just 3 seconds, while top speed is rated at 229 mph.
