LS ENGINES have a great reputation for making power, so it\u2019s hard to get noticed amongst the crowd these days, but Matt Smoors\u2019s 950hp supercharged LQ9 certainly makes an impression.<\/p>\n
Back when Powerhouse Engines<\/a> first put this combo together it made just over 900hp from 370 cubes, with a hydraulic-roller cam and stock rocker gear. That was good enough to power Matt deep into the nine-second zone with his FSTGMH VK Commodore<\/a>.<\/p>\n After two years of solid use and abuse, Matt decided to take the engine back to Johnny at Powerhouse to give it a check-over and see if they could find some more grunt.<\/p>\n Other than some wear on the tips of the valves, the engine looked perfect. So the guys decided to switch the heads to a set of Johnny\u2019s own Power Heads and use lash caps to spread rocker load over a larger area \u2013 it\u2019s also cheaper and easier to replace a lash cap than it is to replace a valve. Using the same hydraulic-roller camshaft, same 12psi boost and same 2.4L Magnuson supercharger, the engine screamed its way to 951hp at 7500rpm with a massive 767lb-ft of torque.<\/p>\n Now 50hp extra might not seem like a whole lot when you\u2019ve already got 900 horses on tap, but those additional ponies saw the VK go from a best of 9.30@150mph to 8.98@153mph within just a couple of meetings. As you can see from the video, the Commodore is a bit of a handful on the track, but more importantly, it\u2019s a genuine eight-second street car.
