If you are on dial-up, grab a coffee... After smashing first gear at the Nostalgia Drags it was time to strip down Cranky's engine. After all Mike Kristen had completed seven 9 second passes and a bunch of low tens at over 140mph. The strip down was almost unneccessary, the engine showed no signs of wear or damage. We took the opportunity to get some pics of the engine as it was reassembled. An opportunity for those that have heard its healthy hunt in the staging lanes and seen it rocket down the quarter to look inside the fastest Volkswagen cased Veedub in Australia. The dual custom made burst valves Fuel distribution for the hat nozzles. Two injectors are loacted above each blower The crank is a factory Volkswagen item from a 2.1 litre water cooled boxer. Counterweighting is essential. Notched 94mm forged pistons and custom made barrrels Ratio roller rockers Rear view of the Toyota 4AGZE blowers The cam is a custom billet job - roughed out in-house and finished by a well respected QLD cam grinder The crankcase is a 2.1 litre wasserboxer. The water jackets machined off to accomodate the aircooled cylinders Extemporaneous parts of the casting such as the oil filter are blocked, others are bored out for other uses (the factory filter is dispensed with for a System 1 filter The combustion chambers of the modified autocraft heads Much time was taken by Mike with the die grinder to make this baby breathe The heads are serviced by sponsor Ultra Torque Heads Placing the crank These rods are taking plenty of abuse from the boost being produced by the dual blowers The cam gear is adjustable allowing very precise dialing in of angle Preparing to close the case Instaling the cylinders, pistons and heads Another view of that intake The push rod tubes are spring loaded and can be removed or checked without removing the head Another 4 injectors are positioned after the plenum, one for each pot The methanol is fed via a hilborn pump The pushrod tubes installed (engine is upside down) The blowers and plenum from the front The twin blowers on the crankcase Adding the tensioner and idler The engine in the car The transaxle features Albins gears, is in kombi configuration and utilises unis rather than cv joints due to the torque of a blown engine. The rear has been narrowed a total of some 6 inches Narrowed adjustable front end An MSD 6AL controls the ignition [ Edited on 23-5-2006 by HotRodMatt ]
