We replaced the original motor with an XV Motorsports built 5.7 Hemi that uses all-forged internals, a trick XV aluminum manifold and our own Holley carburetor. The idea being that a .20 over, balanced and blueprinted V-8 that runs a carb would be much more reliable than the OE fuel injection with a plastic manifold. Sean Hyland built this motor and it’s proven to be stone-axe reliable over thousands of race and testing miles.
Since the motor and transmission are not talking to each other via a common computer, we had to have an extensive gauge package. We chose Nordskog gauges for their ultimate reliability and high tech features.
For reliability and simplicity we run two AEM built Mopar ignition computers. The software is great because it permits us to data log, change parameters, and monitor air/fuel ratios. We also use a separate AEM air fuel gage on the co-driver’s side, so we know when to change filters, or if we have a clogged jet or other problem. With a carburetor that runs volatile 110 octane reace fuel, fire is a real concern. Open float bowls during a rollover are not good. For this reason we use an automatic fire suppression system. One pull of a lever and the engine bay and cab fill with foam.
Under the hood there’s a lot going on. Two huge Fox 4.3 inch bypass shocks provide maximum bottoming resistance while two Fox 3.0’s provide control. Class rules mandate that stock brakes, radiator and steering components be retained. It takes some creative thinking to make it all work.
Two transmission fluid coolers, one engine oil cooler, two fuel cells and four big shocks make it happen out back. For safety, all fueling is done on the driver’s side while the exhaust exits on the passenger side.
