Accordingly, the ARB reserves the right to conduct additional emission tests, in the future, as such tests are developed, that will more adequately measure emissions from all cycle phases. If such test results demonstrate that the T.P.I.S. Z—28 Kit adversely affect emissions during off—cycle conditions (defined as those conditions which are beyond the parameters of the Cold—Start CVS—75 Federal Test Procedure), this Executive Order shall be effectively rescinded as of the date the test results are validated.

Z—28 KIT DESCRIPTION Tuned Port Induction Specialties, Inc.‘s T.P.1.S. Z—28 Kit has been specifically designed for installation on the following General Motors vehicles equipped with a 5.7L engine:

Vehicle Vehicle Vehicle . Engine Disp. Make Mode] Model Year Trans (liters) Chev/Pontiac Camaro/Firebird 1993/94 All 5.7 Chev/Pontiac Camaro/Firebird 1995 Manual 5.7 GM All B Bodies 1994 All 5.7 (Caprice type) . — Chevrolet Corvette LTl 1992—94 All 5.7 Chevrolet Corvette LTl 1995 Manual 5.7 The modified engine operates in conjunction with the original equipment manufacturer‘s (OEM) computer controlled fuel injection system and emission control system already certified with the stock engine. Tuned Port Induction Specialties, Inc.‘s T.P.1.S. Z—28 Kit modifies the engine using new and reworked components. The kit includes a modified camshaft, throttle body, intake manifold, cy]inder heads, headers, modified PROM, adjustable fuel pressure regulator, and an air foil. The new camshaft, when compared to OEM, is altered in lift by 7.1 percent on the intake lobe and by 13 percent on the exhaust lobe. Intake and exhaust duration is altered by less then 1 percent. The stock throttle body (48 mm) is replaced by a 52 mm throttle body. Stock cylinder heads are machined at both exhaust and intake ports to allow for better port matching with the exhaust headers and intake manifold and the valves are replaced by oversized intake and exhaust valves (2.0" intake and 1.56" exhaust). The stock exhaust manifold is replaced by a 16 gage coated mild steel header. On vehicles with a removable PROM, the idle is increased by 150 RPM. An adjustable fuel pressure regulator and air foil installed on top of the 52 mm throttle body is also included. V. DISCUSSION OF T.P.1.S. Z—28 KIT Tuned Port Induction Specialties, Inc. has requested that the T.P.I.S. 7—28 Kit be exempted for applicable 1992 to 1995 General Motors vehicles. A 1994 5.7L Camaro equipped with the T.P.1.S. Z—28 Kit was used as the test vehicle. Tuned Port Induction Specialties, Inc. performed testing at

Automotive Testing Laboratories, Inc. in New Carlisle, Indiana, to be compared against the vehicle‘s emission standards. The results of the exhaust emissions test performed at Automotive Testing Laboratories, Inc. are shown below. CCVSs—75 TEST RESULTS NMHC co NOx Device with DFs Applied 0.23 1.5 0.4 Standard 0.39 7.0 0.4 The CVS-?S emissions test results at Automotive Testing Laboratories, Inc. indicate that the NMHC , CO and NOx emissions of the vehicle, with the T.P.1.$. Z—28 Kit installed, are at or below the emission standards set for that engine family. The Air Resources, Board did not conduct confirmatory testing to validate the emission test results submitted by Tuned Port Induction Specialties, Inc.
