  1. GTO Oil Cooler R&D, Part 4: Temperature and Pressure Testing

    GTO Oil Cooler R&D, Part 4: Temperature and Pressure Testing

    Before completing this project, we need to evaluate the performance benefits of adding this GTO oil cooler. We are confident that our cooler location is receiving ample airflow, so we should see a nice drop in oil temperatures.

    Test Conditions and Apparatus

    We have two different tests to conduct for this particular kit. First, we will record temperature and pressure data to determine the improvement in efficiency.

    To provide accurate data, we need to ensure that our process is repeatable and reduces as many variables as possible.

    Conditions

    • Driving: 65 mph highway cruise
    • Time: 5 minutes
    • Ambient temperature: 68°-75°FNo thermostat installed

    Apparatus

    ·         AEM AQ-1 Data Logging System

    This type of test is not as strenuous as most would anticipate for a performance product. The data we obtain will provide the most accurate comparison of

  2. The Dyno Results - Camaro SS Intake, Part 3

    The Dyno Results - Camaro SS Intake, Part 3

    We have undertaken an intriguing project. The stock intake design for this 2016 Camaro SS is quite unique and working to increase performance has been a challenge, but here at Mishimoto, we welcome challenges! In the previous post, we went through the different iterations our Engineering Team had created, and we designed a prototype for testing. More testing was needed, however, before we could achieve the level of performance we wanted from this design. We will go through a detailed analysis of our final numbers for this Camaro cold-air intake project.

  3. GTO Oil Cooler R&D, Part 3: Line Route and Thermostat Inclusion

    GTO Oil Cooler R&D, Part 3: Line Route and Thermostat Inclusion

    Any efficient oil cooler setup needs proper regulation if the vehicle is going to see street use. As many know, cold oil can be just as harmful as oil that is overheated. Allowing engine oil to come up to temperature prior to romping on the throttle is a wise move that will extend the life of your GTO LS. Ideally, you would want the oil at operating temperature as soon as the key is turned. This is typically not possible on a first start, but the quicker it arrives at operating temperature the better. This is why we are including a thermostatic option for this kit, and we highly recommend its use in any street car with this kit installed.

    Line Route

    We found the best route for our oil lines would be to run them across to the driver side of the front bumper area, winding around the radiator support, and eventually mating with our adapter on the oil filter housing. This route provides an ideal line angle coming into the adapter, as well as a good location for

  4. GTO Oil Cooler R&D, Part 2: Oil Cooler Bracket Fabrication

    GTO Oil Cooler R&D, Part 2: Oil Cooler Bracket Fabrication

    In our last post, we selected an ideal location to mount our cooler, so now we need to develop and fabricate a set of brackets to rigidly mount our large 25-row heat exchanger. For this task, we have a full fabrication shop and many bright minds at our disposal.

    GTO Oil Cooler Mounting Bracket Fabrication

    We opted to utilize the upper grille ducts shown in our last post, which should provide ample airflow to the heat exchanger. With more airflow hitting the core, we should see impressive heat transfer.

    We began this project by capturing measurements and dimensions from the points where we want to mount within the front grille area. Once complete, we drew up some rough plans for the bracket shape and modeled them in Solidworks. These models were then flattened and printed out in template form.

  5. Pontiac GTO Oil Cooler R&D, Part 1: Oil Adapter and Initial Development

    Pontiac GTO Oil Cooler R&D, Part 1: Oil Adapter and Initial Development

    We reached out to the forums earlier this month with a request for a GTO owner to lend us his vehicle for product development. The response was substantial. Our inbox quickly filled with messages from enthusiasts willing to help out. We got a similar response last year when we developed an aluminum radiator for the goat. Before jumping into this GTO oil cooler product development, we want to extend a huge thank you to the GTO community for supporting us and for offering recommendations on new projects and product design.

    The Test Subject

    Our test vehicle came all the way from New York, brought to us by a generous fellow named Tom. This model, a 2004, features a bold Yellow Jacket paint scheme along with a manual transmission. Very nice combination!

    Mishimoto Pontiac GTO Performance Aluminum Radiator

    Product Introduction and Goals

    Our team has received numerous requests for a reasonably priced, high-performance aluminum radiator for the new-age Pontiac GTO. After reviewing the project and evaluating the current offerings available, we found a vacancy in the market. Our target would be to design a direct-fit unit that provides additional cooling and reliability over the stock radiator with plastic end tanks, while still maintaining a reasonable price point. Although it was available for only a few years in the States, the Pontiac GTO (OK, it's a Holden) was a seriously unique vehicle. The LS engine combined with an optional manual gearbox was ideal for a quick street car or a fun weekend track or autocross car. These cars may be a touch heavy, but thanks
