  1. Keep your Cool- Transmission Cooler R&D, Part 2: Prototype Fitment

    Keep your Cool- Transmission Cooler R&D, Part 2: Prototype Fitment

    In our last post, we took a look at the stock Mustang automatic transmission cooler and our plans to make it even better. We designed the cooler in Solidworks, based off the measurements obtained from both the GT and the stock cooler. We will be doing our R&D with this bold yellow GT, but based on our research, this cooler will fit all models of S550 Mustang including the EcoBoost and V6. But enough about fitments, the prototype is complete! It is time to see how well our digital design translated into a real-life prototype.

    So far the trans cooler is looking good. It is much larger than the stock cooler, 50% larger to be exact. The stock cooler comes in at 10 rows, where the

    Keep your Cool - Transmission Cooler R&D, Part 1: Prototype Design

    Over the past year we have been getting acquainted with our Mustang GT, and in the process we've developed an entire line of cooling products for it. In the spirit of staying cool, we are on to our next project, the Mustang GT Automatic Transmission Cooler.

    Heat is generally the enemy of an automatic transmission. In fact, the Ford factory service manual notes that when the GT's computer senses the transmission overheating, it will limit RPMs until the temperature returns to a normal range. There is nothing worse than a track day ending early due to high temps of any kind, including in the transmission. Whether you are taking your GT to the track

    Working on a Cooler Coyote- Oil Cooler R&D, Part 4: Testing

    In our last post we took a look at the fabrication of our all-new bar-and-plate oil cooler designed specifically for this project. Now that we have our coolers complete, it is on to testing. We will test our large bar-and-plate cooler, our small bar-and-plate cooler, and our traditional-style 19-row cooler. This will allow us to compare the effectiveness of our new design to the excellent heat exchangers we already offer.

    Testing

    We installed each version and gave them a chance to show us what they could do in not one, but two arenas of performance. Round 1 Fight!

    Contenders:

    • 19-Row Mishimoto Oil Cooler
    • Small cross-flow bar-and-plate cooler
    • Small dual-pass bar-and-plate cooler
    • Large cross-flow bar-and-plate cooler
    • Large dual-pass bar-and-plate cooler

    We hooked up our 19-row cooler to our GT, as well as our all new bar-and-plate coolers, both large and small, and let them duke

    Let Your Ponies Be Heard - Exhaust Component R&D, Part 6: Test Results

    In our last post, we took a look at the axleback fabrication process. Now that our prototypes are on the GT and ready to rock, it is on to testing! While we were not expecting much in the power department out of these exhaust options, we still wanted to see how they sound on the dyno.

    Let Your Ponies Be Heard - Exhaust Component R&D, Part 5: Axleback Fabrication

    Last time we wrapped up our resonator-delete testing, and with that component good to go, we're on to our next conquest, axleback exhausts. If you have not had a chance to take a look at our resonator deletes check out our blog posts HERE.

    Axleback Fabrication

    Any living, breathing car enthusiast knows that the exhaust is an important modification for modern muscle. Most owners want to rid themselves of the stock sound and let their pony car be heard right out of the gate. Being s550 owners ourselves, we want to hear the unrestricted growl of the Coyote in our GT, so we set out to design some axlebacks. We intend to design a few options as we want to offer an exhaust for every taste.  We plan to test a straight-pipe option for those who want to hear the GT scream, a small-muffler option for those who want an aggressive note but have neighbors, and a large-muffler option for those who like

    Working on a Cooler Coyote - Oil Cooler R&D, Part 3: Cooler Fabrication

    In our last post, we took a look at the fabrication of our oil cooler bracket and the prototype heat exchanger. We've settled on the final bracket design, and now we are moving on to the heat exchanger.

    Heat Exchanger Fabrication

    The lead engineer on this project, Dan, plans to test several designs, including an all new heat exchanger design for this project. Exciting stuff! Before we test, we first need to fabricate our test subjects with the help of our expert welder, Mike. We will be creating a small cross-flow oil cooler, a large cross-flow oil cooler, a small dual-pass oil cooler, and a large dual-pass oil cooler.

    We began with the cores of our new oil cooler designs. First up was welding the mounting points to the top edges of our cores. We have a pretty cool mounting design for our oil cooler, and we were pretty excited to see it come together.

    Let Your Ponies Be Heard - Exhaust Component R&D, Part 4: Test Results

    In our last post, we wrapped up the fabrication of our X- and H-pipes. Now that we have some excellent looking prototypes, it is time to put them to the test. We are not expecting much in the way of power with this modification; however we still want to give these resonator deletes the rundown for sound benefit.

    In addition to testing for any power increase we may see with our resonator delete, we will be testing our three different X-pipe designs to determine which one we will proceed with.

  8. The Mustang GT Intake R&D, Part 1: The Stock System

    The Mustang GT Intake R&D, Part 1: The Stock System

    We've had our Mustang GT for a good while now, and it's time to begin our development of the performance intake. We'll begin by quickly dissecting the stock system and deciding on the direction we'd like to go with our design.

    The stock intake is fairly standard; from the center-mounted throttle body, the intake tube extends toward the driver side of the engine bay and incorporates the curved design that embodies the style of that classic V8 intake.

    One Rad GT - Radiator R&D, Part 2: Final Prototype

    In our last post we took a look at our plans for the Mustang radiator and how we were designing it in Solidworks. Thanks to the speedy design, our first functional prototype is complete and ready for some test fitment!

    Straight out of the box, it is quite a hefty unit and should provide some much needed cooling for this GT. Check out some installed photos of our functional prototype.

    Working on a Cooler Coyote - Cooler R&D, Part 2: Bracket Fabrication

    Prototype Bracket

    Last time, we looked at how we began our bracket design and also the location of the oil cooler. Our design has certainly progressed since then. After we were certain of the dimensions of the bracket, we ditched the cardboard for some steel. Using our waterjet the engineers cut out our first functional prototype bracket. The waterjet is one of our newest tools and has been making development a breeze, as it allows us to make much more precise prototypes compared to fabricating them by hand.

    The bracket will be bent and the tabs in the center will fold together to better emulate the stock component. If you have noticed all of the small circles
