OK, this is over the top. A friend sent us a link to CVperformance.com.au, where we watched a Procomp Motorsports and CV Performance--sponsored Mustang at Sydney Dragway in Australia knocking down a 5.95/260.31-mph pass that was so quick that the video looks like the film was sped up. A starting line video shows the big block Ford crossed up on one pass so badly that the left front tire was off the pavement, sliding and black-tracking the tires. Driver/owner Rob Campisi kept his foot buried and pulled off that amazing run and several others at around the same speed and e.t. What's even more crazed is that according to CV Performance's Con Elfes, the Australians have only one quick class called Super Sedan (SS) for all cars 10.99 and quicker. In the videos, this big block Ford Mustang is staged against a hapless Camaro driver dialed in at 9.95 at probably 150 mph. The poor Camaro looks like it's running about 60 mph when the Mustang blows past. In reality if the Camaro was running 150, the big block Ford Mustang was pushing a 90-mph speed differential! The CV Performance guys lay claim to the world's fastest Mustang. They're probably right. The story behind the effort can be traced to the U.S. and Pro Mod entrepreneur Mike Moran of Moran Motorsports. Mike did all the CNC work on the intake manifold, adapting the pair of 500-lb/hr injectors in each cylinder. That isn't easy when the injectors are positioned at different angles. Mike did all the tuning on the engine electronically, literally while Campisi was making passes at the dragstrip. We've heard that life in Australia is like the way it used to be in the Wild West, and after watching that video, we believe, baby. We had to know more about the power behind this amazing achievement, so Moran and Elfes responded with some technical tidbits we're passing along.
1. Moran tells us these are Garrett 106mm turbos that cranked out 52 psi on the 260-mph pass.
2. Elfes says the Ford A-460 CNC-ported heads sport Jesel rockers, and the cam is driven by a Danny B beltdrive. Other than it being a mechanical roller, mum's the word on the cam. More than likely, we're talking 0.900-inch or more valve lift, but cam timing on turbo cars is often very mild.
3. Moran also says this is a Waterman engine-driven fuel pump that has to be capable of pushing an enormous amount of fuel to support a 3,000-plus-horsepower EFI engine with massive boost. According to Moran, at maximum fuel demand, the system is flowing 16 gallons of alcohol per minute. That is a quart of fuel pumped every second at roughly 100 psi.
4. Moran did the CNC work on the cast-aluminum four-barrel intake fed by a Wilson 5--inch throttle-body that gets plenty of pressure from the pair of turbos. This beast needs a lot of fuel--especially alcohol. There are a total of 16 individual 500-lb/hr injectors from Mike Moran Motorsports. That, folks, represents a flow rate potential of 8,000 pounds of fuel per hour!
5. Big Block Ford The foundation for all this power is a Roberts Design (RDI) Ford aluminum, water-jacketed block with a Bryant crank and GRP aluminum rods. A typical 632 Ford could be as radical as a 4.60-inch-diameter bore with a 4.75-inch stroke, which is not difficult on a 4.900-inch bore spacing block. There's a five-stage dry-sump to keep it all lubricated.
