"This V8 is AMG's first fully developed engine, but when you consider that the company was formed in 1967 as an "engineering office for the design and testing of racing engines" it's amazing it hasn't done one before. The 90-degree V8 is a sand-cast, all-aluminium alloy unit, with closed-deck construction for stiffness and pistons running directly in aluminium bores coated with a twin-wire arc-spray process. It's a short-stroke motor, with Carillo-style con-rods cracked open across the main bearing web and bolted back together around the forged crankshaft so the mating surfaces are infinite and almost self locking, resisting movement in all but one plane. Each piston is more than four inches in diameter, made that way to get the required torque, and to improve the sluggish cylinder charging that might result from such fat bores, the intake ports are vertical so the fuel-air mix just falls into the cylinder.
The engine weighs only 439lb and follows AMG racing practice, including the single Duplex chain that drives all the camshafts off the nose of the crank. AMG's powertrain director Bernd Ramler reckons his V8 could rev a lot harder than its 7,200rpm red line, but this unit has to last for several hundred thousand miles in the C-class and its other applications, so caution is the order of the day. The extra oil-control ring on the cutaway pistons and hydraulic bucket tappets are there for longevity. Eventually, the unit will be fitted with a couple of turbochargers to boost its power to yet dizzier levels."
Ziekelijk vet. Perfecte velgen, alleen het interieur is niet 100% mijn ding.
Dit optisch volledig standaard laten, een valved exhaust erop en misschien nog wat motortuning richting 600 paarden...
Nog altijd m'n jonge droom-SL.
