MILL OF THE MONTH

THIS boost-snorting beauty is the heart of Drag Challenge veteran Phil Edmondsonís eight-second XB coupe (see page 60). As you can imagine, hurling a 1700kg Falcon down the tarmac at such a pace requires just a tad more power than it left the factory with: a snazzy 1423 Clydesdales, to be exact! The man behind the muscle is Rino Conte of RC Performance, who was responsible for the entire build of this turbocharged 383ci Clevor. Starting with an SVO 9.2in-deck block that Phil picked up second-hand, Rino added a forged Scat stroker crank and a set of Oliver rods, while the slugs are custom-made CP jobbies that bring the static compression down to a very boost-friendly 8.2:1.

The current combo is copping some shiny new upgrades before this yearís Drag Challenge that should see Phil run deeper into the 8s: a tighter converter, new 88mm billetwheel BorgWarner courtesy of Forced Inductions in the US, and a larger twin 3.5in stainless exhaust Valve control is courtesy of a custom Comp solid-roller cam pushing Isky Red Zone lifters; the fellas arenít keen to divulge exactly how shapely its lobes are. To keep the combustion internal there are a pair of CHIís wonderful 225cc 3V aluminium heads, which were then given a thorough seeing-to by Rinoís diegrinder. The combo is crowned by a matching CHI single-plane manifold that didnít escape Rinoís touch either; he hogged out the inlet to 4500 Dominator size and massaged the ports to suit the heads.

The snail is a BorgWarner S480 that squeezes ingested air to 25psi before a Chiseled Performance water-to-air intercooler drops the temperature, and boost control is handled by a 60mm Turbosmart wastegate and Raceport blow-off valves.

E85 is delivered to the hungry Henry by a rear-mounted MagnaFuel Pro Outlaw 1000 mechanical fuel pump driven by a Waterman cable drive, and is squirted into the cylinders by Injector Dynamics 2000cc injectors.

Front accessories include a Moroso vacuum pump mounted on brackets made by Philís mate Barry Van Laatum, and a Meziere electric water pump to help control engine temp in any situation. The fires are lit by an octet of ICE 20-amp LS coils, and the whole shooting match is managed by a FuelTech FT600 ECU. All of the hot and cold plumbing, the throttle elbow, four-inch dump pipe and the steampipe turbo manifolds were knocked up by Andy at Adelaide Motorsport Fabrication.

The coupe sees a lot of service on the street as well as the strip, so itís a good thing itís a doddle to drive. ďPeople expect it to be loud and aggro, but when itís not on boost it cruises like a mild 351,Ē Phil says. ďIf anything, itís too quiet!Ē
