![]() ![]() Ford also upgraded the oil cooler to include a bypass at the lower coolant hose, so the oil temps stay in check. Some of the other additions to the 5.2L Raptor R is a decoupled pulley on the supercharger to protect against any kickback from the crankshaft. The Raptor R is carrying around 8.5 pounds of weight for every horsepower versus the TRX’s 9.2, giving it a nearly eight-percent better power-to-weight ratio.” So while, yes, it’s down two horsepower versus the Ram TRX, it’s also down 400-plus pounds. “It’s made to crush the off-road world at speeds that would break your Camry to pieces. It seems Ford simply didn’t want to initiate a horsepower war.”įord’s focus (no pun intended) was making sure the Raptor R could sing at high revs while blasting dunes as long as the driver desires, Fenske says. The weather forecast will make a bigger difference than that, and also keep in mind engines can be marketed below their true rated power. Why didn’t Ford give the Raptor R another three horsepower for a subtle jab? But with only a two-horsepower difference, we’re talking about less than a third of a percent. “It has just two more horsepower and 10 more pound-feet of torque. The Ram TRX does technically have more power, but only slightly, according to Fenske. But the Raptor is quite a bit lighter and produces a better power-to-weight ratio than the TRX. With the Ram TRX producing only slightly more horsepower, you would think Ford messed up. “Mostly in jest, I asked why not side pipes like Mercedes does with the G-wagon?įord says they want to make sure the exhaust is above the vehicle side rails since it’s an off-road vehicle and the exhaust could get pinched. ![]() The downside of an application like a truck, according to Fenske, is that the exhaust has to travel back a very long distance, which adds resistance, and there’s really no way of avoiding this because trucks are long. The Raptor R veers from the GT500 header design and instead uses a cast stainless-steel exhaust manifold for durability, which is the name of the game since it’s a truck application. Fenske says that one of the big benefits of this plasma spray, aside from it being lightweight and durable, is that it allows for more space within the cylinders, thus giving you a bit more displacement versus an iron sleeve. The Raptor R engine also employs Plasma Transfer Wire Arc “spray-in” cylinder liners that Ford’s been using in production since 2011 with the 5.4L supercharged GT500 engine. The supercharger displaces 2.65 liters of compressed air into the engine for a ton of power and torque at low RPM. Another addition to the Raptor R is the rather-large Roots-style supercharger with an internal intercooler. ![]()
