As if anyone really needs any more proof of just how awesome FAST’s LSXr 102 manifolds [1] are, here we have a bit of video evidence of the kind of power gains these manifolds are capable of. This video we came across on YouTube features a 2005 LS2 Corvette that is far from stock; sporting a set of American Racing full-length headers, a 3” Borla exhaust, and a ported throttle body in addition to the FAST 102 LSXr Intake Manifold. To do the before and after tests with the FAST LSXr manifold [1], the car was taken to the New Era Performance shop in Rochester, New York.
As a baseline run with its existing mods the C6 made a suitable 372 horsepower and 373 pound feet of torque at the rear wheels. After installing the FAST LSXr intake manifold it was back to the DynoJet [2], where the Atomic Orange Vette’s power jumped to 393 horsepower, and the torque reading jumped all the way to 402 pound feet. That’s a total gain of 21 horsepower and 29 pound feet of torque just from a relatively simple intake swap, and as the video points out that’s enough to produce a “major kick in the pants on the ‘Butt Dyno’.” Be sure to check out the video, and hit up FAST’s website [1] for more info on the LSXr Intake Manifold.
