It’s all well and good that the Lamborghini Temerario’s four-liter, twin-turbo V8 engine jets 789 horsepower before the electric motors are even factored in. But there’s a sense that once that powertrain netted that extra EV assistance, the Temerario lost at least part of what makes a Lambo special. If you feel the same way, a fella by the name of David Dicker just built an engine more Lambo in feel than the real thing.
In truth, it’s a lot closer to an old-school F1 V10 than a modern Lamborghini. Mostly because this one’s got ten cylinders and the Temerario, enragingly, only comes with eight. What we have before us is called the RC.TEN. It’s a four-liter, naturally-aspirated V10 racing engine built in-house by David Dicker’s self-founded company, Rodin Cars.
If Lamborghini’s plan for the Temerario’s V10 was to build the best possible ICE powerplant to supplement its suite of electric motors, this New Zealand shop simply tried to build the best racing V10 in the world, full stop. This is fairly evident when you take a look at this marvel of an engine. Even for its size, the cast aluminum engine block and cylinder heads look far smaller than its 3,998 ccs (224 ci) of displacement leads on.Add a clever dry-sump oiling system and an ECU tuned for sustainable 102 RON racing fuel, and this is the kind of engine that feels just as home racing endurance competitions as much as it does a point-to-point, quarter-mile drag race. Only David Dicker’s keen prowess in metal machining, 3D printing, and working with finicky composite materials makes constructing an engine of this caliber remotely possible.From the bare engine block to a fully completed racing drivetrain build, each step of the fabrication process is painstakingly overseen by David and put through a rigorous multi-point quality inspection before delivery, just like an OEM racing engine from more popular manufacturers. What results is an engine that, even without forced induction, jets 720 horsepower at the crank and 530 Nm (390.9 lb-ft) of torque while revving up to an ear-destroying 12,000 RPM by the time it red lines. For some context, the V8 in the Temerario runs out of puff at around 10,000 RPM.But, of course, any decent N/A engine worth its salt has people salivating at the thought of adding twin turbos. Rodin Cars has your back there, too, to the tune of 11 psi of boost pressure offered by two massive turbochargers. In this outfit, including beefed-up internals to handle the extra boost, you’ll be squeezing over 1,000 horsepower at the crank.
Can you imagine what this translates to when the RC.TEN’s shoved under the hood of a race car that weighs less than a thousand kilos?The answer is absolutely mind-bending speed every day of the week. One can only hope the Rodin Cars service department is as robust as Lambo’s because this engine is a prime candidate to make blow up on race day.
