One sports car that really needs more power is the Chevrolet C6 Corvette Z06, right? The LS7 engine puts out 505 horsepower in stock form, so it could really use about twice that. Thankfully the folks at APS (Air Power Systems) developed a twin turbocharger kit for the C6 Z06 application. APS claims their power adders will get the LS7 generating upwards of 1100 rear wheel horsepower. Now, knowing the compression ratio of the LS7, the upper reaches of that power range will not be seen by anyone running pump gas. Regardless of the user's intended boost setting, the kit will esthetically fit in with the rest of the ZO6's engine bay. A few notable parts included in the kit are cast iron exhaust manifolds, rotomolded plastic intake piping, water cooled turbochargers and an oil scavenge pump to ensure the proper lubrication of the turbocharger bearings.

      Are those oil coolers or intercoolers? I think this will have a huge knocking problem unless the figure out how to get more charge cooling on there.

      Also, having the bypass valves before the intercoolers is not what I am used to. Will that work better or worse than near the throttle plate?
        • 7 Years Ago
        why not the LS2/LS7?, yes, ideally the bypass valves would be best just short of the throttle body but isn't completely necessary with lower boost levels and modern turbo chargers.

        Of the 3 coolers shown it looks like twin side mount air to air coolers and the center is probably for oil.

      to make 1100 hp, the bottom end would have to be rebuilt. the cast alum pistons would have to go but the stock forged crank would be fine.

      i wonder if you could hold the 7k rpm redline with internals that can stand up to the boost. i suppose anything is possible if you are willing to spend enough money

        Their website lists twin GT3582s which are more than capable of 1100whp.

        Naggs, there are plenty of internals that can withstand the forces. Guys in Japan and the US have been making 1000+whp out of 2.8L-3.2L inline-6s spinning 9k-10k rpms. The rods, etc. in those motors are seeing way more force than the rods in the LS7 would see at the same torque/power levels.

        Ryan Woon ran ~1600 RWHP on a 3.4L stroker supra single turbo 2JZGTE (T88 or something crazy, mind you), so yes, it is very feasible indeed.

      Increase the stroke(screw the 7K redline), put on similar heads with larger combustion chambers to lower the CR, Get a cam with a little more of everything and it should be pretty sweet. I'd like to see a roots supercharger with 14 lbs of boost though.

      These guys did it to a Ford GT:


      I can't imagine what it must feel like.

      Incredible!! I've got to see this in a Z06!
      • 7 Years Ago
      dang, very nice numbers, It's gonna need some crazy tires though

      Naggs- the LS7 has cast pistons?????? news to me.
      Tiger- cast iron manifolds are used because they can actually take the heat.
      1100hp in a C6 vette could certainly go 250mph, the Sledgehammer C4 did. One of the big limiting factors is cooling, though, not just "inter" cooling. A radiator has to expel huge amounts of heat. Thats fine for a few seconds down the drag strip, but it gets dicey past that.
