State of California AIR RESOURCES BOARD EVALUATION OF CRANE CAMS, INC. COMPUCAM 2000 SERIES FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS by Mobile Source Division State of California Air Resources Board 9528 Telstar Avenue E1 Monte, CA 91731 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does the mention of trade names or commercial products constitute endorsement or recommendation for use.)

SUMMARY Crane Cams, Inc. has applied for an exemption from the prohibitions of the Vehicle Code Section 27156 for their Compucam 2000 series 2010, 2020, and 2030 camshafts for installation on 1987 and older General Motors vehicles equipped with 267 CID (4.4L) to 350 CID (5.7L) V—8 gasoline engines utilizing feedback or conventional carburetors. Crane Cams has submitted a completed application and all the required information, as well as exhaust emissions test data performed at Crane Emissions Laboratory which demonstrated that the specified camshafts do not have any adverse effect on the exhaust emissions of the affected vehicles. Testing performed at the Air Resources Board (ARB) confirmed the test results of Crane Emissions Laboratory. Based on the submitted information and the results of the emissions tests performed at Crane Emissions Laboratory and the ARB, the staff concludes that the installation of Crane Cams‘ Compucam 2000 series will not adversely affect exhaust emissions on the specified vehicles. The staff recommends Crane Cams, Inc. be granted an exemption as requested and that Executive Order D—225 be issued.

EVALUATION OF CRANE CAMS, INC. COMPUCAM 2000 SERIES FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS I. INTRODVEGTION Crane Cams, Inc. of 530 Fentress Bivd., Daytona Beach, Florida 32114, has applied for an exemption from the prohibitions of Vehicle Code Section 27156 for their Compucam 2000 series 2010, 2020, and 2030 camshafts for installation on 1987 and older General Motors vehicles using feedback or conventional carburetors. Crane Cams has submitted a completed application and all the required information, as well as exhaust emissions test data performed at Crane Emissions Laboratory which demonstrated that the Compucam 2000 series does not have any adverse effect on the exhaust emissions of the affected vehicles.

CONCLUSIONS Based on the submitted information and the results of the emissions tests performed at Crane Emissions Laboratory and confirmatory testing conducted at the ARB, the staff concludes that the Crane Cams, Inc. Compucam 2000 series will not adversely affect exhaust emissions from vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that Crane Cams, Inc. be granted an exemption as requested and that Executive Order D—225 be issued. ~1—

IV. COMPUCAM2000SERIESDESCRIPTION Compucam 2010, 2020, and 2030 are specifically designed for ‘installation on 1987 and older General Motors vehicles powered by 267 CID (4.4L) to 350 CID (5.7L) ¥—8 gasoline engines. The camshafts operate in conjunction with the original equipment manufacturer (OEM) computer controlled feedback or conventional carburetors along with the emission control systems already certified with the stock engines. The purpose of using the Compucam 2000 series camshafts is to increase the overall engine performance by modifying the valve characteristics, such as increasing the valve lift and duration. The three camshafts vary in their characteristics, ranging from moderate to high engine performance. The cam lobes on the Compucam 2010 have been increased by 7.5 percent on the intake and 4.2 percent on the exhaust when compared to the OEM camshaft. These increases translate to a mild increase in valve lift, allowing the engine to increase its volumetric efficiency. The Compucam 2020 is designed to provide a mid—range performance with a 13.9 percent increase on the intake lobe and a 10.2 percent increase in the exhaust lobe. The greatest increase in cam lobe lift is on the Compucam 2030 which has a 20.3 percent increase in the intake lobe and a 16 percent increase in the exhaust lobe. The Compucam 2010 works best on the 267 CID engine while the Compucam 2030 is designed to enhance the performance of the high output 350 CID engine. V. DISCUSSIONOFTHECOMPUCAM2000SERIES A 1984 Chevrolet Camaro powered by a 305 CID engine was used for the evaluation of the Compucam 2000 series camshafts. Documentation given to Crane Cams by General Motors indicated that a prom change would calibrate their Camaro to California specifications. This information was verified by «2—

the ARB during the application process and confirmatory testing. The dynamometer inertia weight and loading used during the testing were 3625 lbs. and 7.8 hp, respectively. Emission tests conducted by Crane Emissions Laboratory consisted of cold—start CYS—75 emission tests with the Compucam 2030 installed on the test vehicle, and the vehicle calibrated to California configuration. This test was used to compare vehicle exhaust emissions in the modified configuration with the applicable emission standards. The test results are shown in Table 1. Table 1 CVS—75 TEST RESULTS (Crane Emissions Laboratory) HC CQ NOx Emission standards 0.39 7.0 0.7 Baseline #1 0.38 4.98 0.66 Baseline #2 0 .38 4.8 0.66 Average baseline 0.38 4.89 0.66 Compucam 2030 test 1 0.32 3.99 0.47 Compucam 2030 test 2 0.32 4.58 0.44 Average Compucam 0. 32 4.29 0.46 Confirmatory testing was performed at the ARB. The results are shown in Table 2.

Table 2 CVS—75 TEST RESULTS (Haagen—Smit Laboratory) HC CQ NQx Compucam 2030 test 1 0.36 5.84 0.49 Compucam 2030 test 2 0.38 6.80 0.49 Average Compucam 0.37 6.32 0.49 The CVYS—75 emissions test results at Crane Emissions Laboratory and confirmatory testing at the ARB indicate that HC, CO and NOx emissions of the Compucam 2030 camshaft are well below the emission standards. This demonstrates that the installation of the Compucam 2000 series camshafts will not adversely affect the exhaust emissions of 1987 and older General Motors vehicles powered by 267 CID (4.4L) to 350 CID (5.7) V—8 gasoline engines. Crane Cams has submitted all the required information and fulfilled the requirements for an exemption. The test results confirmed that Crane Cams‘ Compucam 2000 series meets the requirements for the exemption.
