    Thats an easy question: LS9!!!!! (Is somebody fishing for what to put in the HVR?)

    That customer Hoover was talking to yesterday I believe was me.

    I mentioned to him that I was at Oswego Speedway to see the Xtreme Sprint cars and the ISMA's, the winged midgets-a pushod V8 fest, and the motors sounded pretty cool, better than the NASCAR engines, more like a freer breathing 'Vette.

    I figured since small block Chevy pushrod V8's are all over the place in boutique sports cars, it might be an option for Noble/Rossion/HVR.

    Cheap and relatively reliable, it might attract the American muscle car fan to the brand.

    LS3/7/9 with a little boost or a Ford multi-valve pushrod could work. Those are actually fairly small and light since the camshafts are within the cylinder block. Sure, they have their limits, but I would think they could make 6-700HP without radical plumbing mods.

    This wouldn't have to replace our turbo sixes-just be an option.

    Bodhii,

    Interesting that you suggested that motor-it's the one in my RS4 sedan, mine's supercharged with Roland Mayer's MTM twin-screw unit, good for 530HP on 93octane, 540 on 95+octane. It serves as my winter beater. The Quattro runs great in the snow:

    The RS4 DI 4.2L V8 is the same motor Mayer twin-turbocharged and put in to the Gumpert Apollo which makes 750HP.

    The factory rates it at 420PS/414HP at the crank, but some dyno runs read lower. Mine was dyno'ed in Montreal at the MTM Canada shop, on 94octane making 380HP and 395Nm/291lb-ft baseline pre-MTM, then 535HP and 599Nm/441lb-ft post-tuning. Sorry these are converted to crank numbers from a Dynapack dyno, but the gains can be seen.

    Hey Al! You would know well. I've always heard that supercharging for race motors is not the way to go because of heat. For the street, they're awesome. Am I misinformed?

    I think one can track with a supercharger, but racing is a different story. I've experimenced problems with belt slippage, belts coming off/ tearing under high loads.

    I have heard the same about tracking/racing a supercharged car (except drag racing), but I have never raced with the RS4, only open track running at less than 10/10's. The unit has a Laminova cylindrical air-water IC which works well controlling heat, but I don't know how it would handle heat soak on the track:
