CONCLUSIONS Based on the submitted information and the results of emissions tests performed at Roush Laboratories, the staff concludes that the Competition Cams‘ Pure Energy camshafts, part nos. 12—207—2, 12—208—2, 12—206—2, 12—314— 4, 12—310—4, 12—312—4, 12—402—4, 12—106—3, 12—400—4, and 12—210—2 will not adversely affect exhaust emissions from vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that the Competition Cams be granted an exemption as requested and that Executive Order D—279—6 be issued. IV. DESCRIPTION OF CAMSHAFT The Pure Energy camshafts, part nos. 12—207—2, 12—208—2, 12—206—2, 12— 314—4, 12—310—4, 12—312—4, 12—402—4, 12—106—3, 12—400—4, and 12—210—2 —1—

camshafts are specifically designed for installation on 1987 and older General Motors vehicles equipped with a 267 to 350 CID carbureted engine. The camshafts operate in conjunction with the original equipment manufacturer‘s (OEM) emissions control system already certified with stock engine. The purpose of using the Pure Energy camshaft is to increase the overall engine performance which is a direct result of modifying valve. characteristics. An example would be an increase in valve lift and duration. The specifications of the Pure Energy camshafts are tabulated in Table 1. Table 1.

DISCUSSION OF THE CAMSHAFT A 1987 Chevrolet Camaro powered by a 305 CID engine was used for the evaluation of the Pure Energy camshafts, part nos. 12—207—2, 12—208—2, 12— 206—2, 12—314—4, 12—310—4, 12—312—4, 12—402—4, 12—106—3, 12—400—4, and 12— 210—2 camshafts. The dynamometer inertia weight and loading used during the testing were 3625 lbs. and 7.6 hp, respectively. —2—

Emission tests conducted by Roush Laboratories consisted of one cold— start CVS—75 emission test. The Pure Energy camshaft, part no. 12—106—3 was installed on the test vehicle with emission results compared to the vehicle‘s emission standards. The test results are shown in Table 2. Table 2 CVS—75 TEST RESULTS (Roush Laboratortes) HC c0 NOx Standard 0.39 7.0 0.7 — Device 0.38 2.87 0.25 These resu]fs show that the modified vehicle emissions do not exceed the véh%é]e’s emfssion standards. Staff did not perfb}m confiffiétory testifié to validate test data submitted by Competitioh Cams. Competition Cams has submitted all the required information and fulfilled the requirements for an exemption.
