This week"s Dyno Blast video features a second generation Chevrolet Camaro Z28 with the split bumper front end of the Rally Sport package stretching its legs on the rollers. The video begins with this monstrous Camaro rolling down the street in the rain followed by a quick walk around of the clean, classic Chevy muscle car. With the big cowl induction hood, the skinny front tires and the fat rear tires, this Camaro looks pretty serious.When the video jumps ahead to the dyno shop, we can see just how serious this 2nd gen Camaro really is, as this machine packs a turbocharged L20 V8. This 4.8L engine would have come out of a GM cargo van or a mid-level Chevrolet/GMC full size pickup, and depending on the application, this Vortec V8 would have offered somewhere in the area of 260-302 horsepower in stock form.Of course, this is no stock motor L20 V8.The L20 V8 in this classic Chevy Camaro has been fitted with an aftermarket camshaft, a Holley electronic fuel injection system, and an 80mm turbocharger which is paired with an air-to-water intercooler. We would guess that the engine has been rebuilt with stronger internals to handle the boost, but based on the details accompanying the video the only internal engine modification is the cam.In other words, this is a turbocharged van engine in a classic Camaro Z28, and it makes monster power.The video first shows the split bumper Camaro make a dyno run on pump gas, followed by a run on VP Racing Fuels C16. We can clearly hear the difference during the runs and when the video comes to an end, the numbers reveal how much of a difference the race gas makes.On pump gas, this L20-powered Camaro Z28 made 611 rear wheel horsepower at 18 pounds of boost while on C16, they were able to run 22 pounds of boost for an awesome 742 rear wheel horsepower.Tags: 2nd Gen Camaro, camaro, Dyno, Dyno Blast, L20, split bumper, Turbo, turbocharged, Vortec
