(Page 1 of 2) State of Calffornia AIR RESOURCES BOARD EXECUTIVE ORDER D—140—2 Relating to Exemptions under Section 27156 of the Vehicle Code SPEARCO PERFORMANCE PRODUCTS, INC. TURBOCHARGER INTERCOOLER KIT NO. 99684 FOR 1984 MASERATI BI—TURBO VEKICLES Pursuant to the authority vested in the Air Resources Board by Sectfon 27156 of the Vehicle Code; and Pursuant to the authority vested in the undersigned by Sectfons 39515 and 39516 of the Health and Safety Code and Executive Order G—45—5; IT IS ORDERED AND RESOLYED: That the installation of the turbocharger intercooler kit No. 99684 manufactured by Spearco Performance Products, Inc., of 7541 Woodman Place, Van Nuys, California 91405, has been found not to reduce the effectiveness of required motor vehicle pollution control devices and, therefore, is exempt froem the prohibitions of Section 27156 of the Vehicle Code for 1584 riasgrati Bi—Turbo vehicles powered by a 2.5 Titer engine. T.« txecutive Order is valid provided that installation instructions for tnis device will not recommend tuning the vehicle to specifications | different from those submitted by the device manufacturer. Changes made to the design or operating conditions of the device, as exemplci hy the Air Resources Board, that adversely affect the performance ofda vehicle‘s pouiuliyn control system shall invalidate this Executive Order. Marketing of this device using an identification other than that shown in this Executive Order or marketing of this device for an application other than those listed in this Executive Order shall be prohibited unless prior approval is obtained from the Air Resources Board. Exemption of a kit shall not be construed as an exemption to sell, offer for sale, or advertise any component of a kit as an individual device. This Executive Order does not constitute any opinion as to the effect that the use of this device may have on any warranty either expressed or implied by the vehicle manufacturer. THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AZR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTIGN BENEFITS OR ANY ALLEGED BENEFITS OF THE TURBOCHARGER INTERCOOLER KIT NO. 99684.

State of California AIR RESOURCES BOARD Evaluation of Spearco Performance Products, Inc.‘s Turbocharger Intercooler Kit Number 99684 for 1984 Maserati Bi—Turbo Yehicles for Exemption from the Prohibitions in Vehicle Code Section 27156 in Accordance with Section 2222, Title 13, of the California Administrative Code. June 6, 1984

Evaluation of Spearco Performance Products, Inc.‘s Turbocharger Intercooler Kit No. 99684 for 1984 Maserati Bi—Turbo Vehicles for Exemption from the Prohibitions in Vehicle Code Section 27156 in Accordance with Section 2222, Title 13, of the California Administrative Code. 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 mention of trade names or commercial products constitute endorsement or recommendation for use.)

SUMMARY Spearco Performance Products, Inc. has requested an exemption from the prohibitions in Vehicle Code Section 27156 for their turbocharger intercooler kit number 99684, intended for installation on 1984 Maserati Bi—Turbo vehicles powered by a 2.5 lTiter engine. Based on: (1)} previous comparative tests evaluating the exhaust emission effects of one of Spearco‘s intercooler kit; and (2) the staff‘s engineering evaluation of the intercooler‘s impact on exhaust emissions from vehicles, the staff concludes that Spearco‘s turbocharger intercooler kit number 99684 will not adversely affect exhaust emissions from vehicles for which exemption is requested. The staff recommends that Spearco Performance Products, Inc. be granted an exemption for their turbocharger intercooler kit number 99684 as requested and that Executive Order D—140—2 be issued.

Evaluation of Spearco Performance Products, Inc.‘s Turbocharger Intercooler Kit Number 99684 for 1984 Maserati Bi—Turbo Vehicles for Exemption from the Prohibitions in Vehicle Code Section 27156 in égg:rdance with Section 2222, Title 13, of the California Administrative 1. INTRODUCTION Spearco Performance Products, Inc., of 7541 Woodman Place, Van Nuys, California 91405, has requested an exemption from the prohibitions in Vehicle Code Section 27156 for their turbocharger intercooler kit number 99684. The kit is intended for installation on 1984 Maserati Bi—Turbo vehicles powered by a 2.5 Titer engine. II. CONCLUSION Based on: (1) previous comparative (turbocharged vehicle without and with an air/liquid intercooler kit) tests evaluating the exhaust emission effects of one of Spearco‘s intercooler kit; and (2) the staff‘s engineering evaluation of the intercooler‘s impact on exhaust emissions from vehicles, the staff concludes that Spearco‘s turbocharger intercooler kit number 99684 will not adversely affect exhaust emissions from vehicles for which exemption is requested. III. RECOMMENDATIONS The staff recommends that Spearco Performance Products, Inc. be granted an exemption for their turbocharger intercooler kit as requested and that Executive Order D—140—2 be issued. IV. INTERCOOLER KIT DESCRIPTION AND OPERATION The purpose of intercooling a turbocharger is to reduce the temperature of the intake air/fuel charge going into the engine. This reduction in intake charge temperature will allow a higher charge density (more mass of air per minute to flow through the engine) which means more fuel into the engine at a given intake manifold vacuum/pressure.

The major components of the Spearco turbocharger intercooler kit number 99684 are two intercooler assemblies, a heat exchanger, a circulating pump, and an electronic module. They are packaged with installation hardware and instructions and sold as a kit. Compressed intake charge passes through the intercooler assemblies. Circulating coolant, pumped by the circulating pump when boost pressure exceeds 4 psi, will extract heat (by conduction) from the intake charge to reduce temperatures over 100°F. The circulating coolant is cooled by passing through the heat exchanger. In order to prevent the coolant from freezing in cold areas, Spearco fecommends a minimum mixture of 10% ethylene glycol or anti—freeze and 90% water. V. DISCUSSION Spearco Performance Products, Inc. is making available a turbocharger intercooler kit for the 1984 Maserati Bi—Turbo vehicles powered by a 2.5 lTiter engine. The kit is similar in design and principle as their previously exempted intercooler kit for 1982 through 1984 Toyota 2.8 lTiter vehicles exempted under Executive Order No. D—140—1. Spearco has previously performed comparative {vehicle turbocharged without and with an air/liquid intercooler kit) tests evaluating the exhaust emissions effects that one of their intercooler kits would have on a 1984 Toyota 2.8 liter Supra. Upon demonstrating no adverse effect on the vehicle‘s exhaust emissions, the intercooler kit was exempted. In addition, it is the staff‘s opinion that the combustion temperature will be reduced as a result of cooler intake charge with the use of the turbocharger intercooler kit. This reduction in combustion temperature will reduce the formation of NOx gases in the combustion chamber, resulting in less NOx emissions expelled through the exhaust system.
