RULEBOOK HIGHLIGHTS All official SI dynamometer tests will be open. All SI competitors have the option to be present for official chassis dynamometer testing. • A restrictor between the throttle body and intake manifold may be used to reduce horsepower and torque. The diameter and thickness of the restrictor plate orifice(s) shall be noted on the dyno sheet and must match at all times. No other means may be used to reduce horsepower and torque. • OEM exhaust manifolds may have a coating that is bonded to the parent material. This includes any paint or ceramic type coatings, but does not include header wraps. • Exhaust from the end of the exhaust manifolds to the exit is unrestricted other than exhaust must exit behind the driver. • The PCM may be relocated to inside the body for protection. The battery may be relocated and may be any size capable of supplying enough current to start the car. • Traction control devices are expressly prohibited. Factory installed units must be disabled. See section 8.8 - Burden of proof that unit is disabled lies with the competitor. i.e.- switch disabled, computer indication, etc. • Rear wheel negative camber may not be more than 0.50 degrees. • Water or other liquid cooling of brakes is not permitted. Air cooling is both allowed and recommended. • Hood and trunk may be "gutted" by removing structure from their underside and their struts and associated brackets may be removed. • The grill and front bumper cover may have openings enlarged or added for the purposes of routing cooling air to allowed components. However, any such modification that improves or appear to improves aerodynamic performance (increased downforce or decreased drag) are not allowed. • All other OEM light assemblies may be replaced with facsimiles, plates, covers, or mesh covered cooling duct openings as long as these maintain the stock external appearance. Replacements for recessed lights must also be recessed. BRETT BECKER 74
