IMSA Technical Eligibility Form Appendix 1) Engine Power Table a. Define Maximum Power (kW) at the driveshafts as a function of relative engine speed (N/Nmax) b. Power at the 1.025 N/Nmax point will be defined by IMSA as -14% from the 1.0 N/Nmax value i. Power(1.025) = Power(1.000) * 0.86 c. Control systems must be capable of supporting power from defined Maximum to -20% of Maximum 2) Sensors a. All sensors must be mounted in accordance with Bosch Appendix in current Scrutineering System Manual. i. Lambda Sensors need to be mounted within 10° of vertical and perpendicular to exhaust flow direction. b. Pressure and Temperature Sensors. i. Driver's left will indicate bank #1. 1. Bank will be fed bank of the engine. 2. Forward manifolds will indicate bank #1. ii. Pressure sensors are recommended to be mounted within 60° of vertical with orifice facing downward. 3) MS6 SCR a. This device must be fitted in the cockpit on the passenger side floor in an easily accessible location. 4) VMPS a. Must be aligned within 1 degree of vehicle centerline. b. Must be aligned within 0.5 degrees of horizontal. c. Must be mounted using supplied mounting bracket. d. Must be mounted nearest to vehicle center of gravity as possible. e. See BSSM for additional information. 5) VMPS Antenna a. Must be fitted to the top surface of the vehicle roof within 200mm of the roof centerline. b. All other antennas on Car, other than the supplied LTE antennas, must be installed at least 240 mm from center of IMSA VMPS antenna. i. Include a visualized restriction zone around the VMPS antenna. c. Antenna must be mounted with heading in the driving direction. d. See BSSM for additional information. 6) X2 Transponder a. The longitudinal axis of the transponder must be parallel with the longitudinal axis of the vehicle and the label side of the transponder must face the ground. b. A non-conductive window may be placed between the transponder and the ground. IMSA highly recommends an Aramid (Kevlar) or fiberglass window. i. The window must extend beyond the edge of the carbon fiber mounting bracket available for purchase from IMSA. c. If two transponders are fitted in the car, must detail both transponder locations. d. 7) Fuel Flow Meter a. Submitted images of mounting bracket and location will be reviewed by IMSA for approval. b. Must be mounted near engine, isolated from vibration and heat. c. Each supply line requires its own individual sensor. i. Low pressure supply line only.
