The search continues to find the optimal blend between a high-quality WOT (wide-open throttle) exhaust sound and a rich sound during normal driving and light-throttle driving situations. In this segment, we continue with our 2015 Mustang exhaust sound testing to see if we find our second or third prototype setup pleasing.

Dyno Testing

We set up our EB on the Dynapack for some more sound collection. We also kept an eye on power output and AFR readings to see if power changed on the factory tune, and to see if the improved flow would impact AFRs in any way. On our 2015 WRX, we saw these readings lean out a bit with the cat-back installed, so we wanted to see if this was the case with the 2.3L!

Automotive passion has evolved over the years, and is still very much alive and well. A lot of this is a result of automakers continually bringing us the best in technology, innovation, and performance. Some will complain that modern automobiles are numb, boring, and full of complicated electronics and gizmos. Whatever your take on this is, one thing is certain. People still love cars, and the impulse to modify vehicles is as strong as it has ever been.

Take the Fiesta ST for example. A compact hatchback, front-wheel drive, economical vehicle. A few bolt-on modifications can turn this into a tire-shredding, corner-carving autocross monster. It is all in how you approach new technology. You can embrace it and take advantage of what we have available in today's age, or you can curse electronic fuel injection, discredit independent rear suspension, and continue to rip around your hometown streets in your SBF-powered Cougar. Not that there is anything wrong with this. The key here is acceptance,

Mishimoto Jeep Wrangler YJ and TJ Performance Fan Shroud Kit

Quite the project this Jeep TJ electric fan shroud kit has been! We've gone through a few design iterations and conducted some pretty cool testing to ensure that our product will adequately cool both the 2.5L and the 4.0L.

Testing Results

The last portion of our article series showed the testing apparatus and our plans for extended idle testing with our Jeep TJ electric fan kit. We would be monitoring coolant temperatures to see the impact of an electric fan as opposed to a mechanical setup provided by the factory.

Testing Conditions

• Ambient temperature: 72°F
• Testing timeframe: 1400 seconds (23.3 minutes)
• Vehicle: Jeep Wrangler

Testing time! It's always fun to see the results when you make changes to your vehicle, whether bolting on a new wheel and tire combo, or installing a  new set of  dampers. In this case, we are expecting our Fiesta ST oil cooler setup to drop fluid temperatures by a substantial margin during our on-road testing.

Testing Setup and Conditions

Testing the stock Fiesta ST oil cooler is relatively simple. Only one temperature and pressure will need to be monitored, so we can utilize our sandwich plate sensor adapter shown below.

Mishimoto Subaru BRZ / Scion FR-S / Toyota GT86 Plug-N-Play Aluminum Fan Shroud Kit!

We're back for some more fan shroud fabrication! The last portion of this series highlighted the beginning stages of initial shroud design. The BRZ/FR-S uses a fairly unique overflow tank that mounts directly to the factory fan shroud. This is our first target for part two of product design.

Overflow Tank Mount Fabrication

This tank has two upper mounting points which use a bolt which passes through the tank material and into threads on the shroud. We utilized round stock aluminum which was cut to the proper length, drilled, and tapped for the appropriate factory bolt. These were then welded to the shroud in a position that would place the tank in the

We're back with more grinding, fitting, cutting, and welding. The fabrication of our intake prototype for the Nissan 350Z continues!

Airbox Fabrication

When we left off, we had fabricated three sides of our airbox and created a 3D model for our MAF-to-filter adapter. The next plan was to continue designing and constructing our airbox, starting with the base.

We mapped out our base on

Interested in purchasing our 6.0L intake elbow?

If you are familiar with our brand, you know we have a vast product line of heat exchangers and associated products available for the Ford 6.0L Powerstroke. We've had great feedback from our customers about our existing products as well as the new products they would like to see come out of our garage. Now that we have our own 6.0L shop truck (shown below), we have easy access to a vehicle for product development and test fitting.

We decided to come up with our own rendition of an inexpensive, free-flowing intake elbow for the 6.0L. Yes, we realize there are ample options currently on the market. That said, we would like our design

First Prototype: Sound

We're starting this article with a recap of Part 1 of this series, which highlighted our first prototype for the 2015 Mustang EcoBoost exhaust design. If you recall, this design featured a midmuffler as well as two rear mufflers.

We promised a sound clip of our first design, so check it out below!

As you can hear, this setup is not quite what we are looking for. Although our mufflers are more free-flowing compared to the stock units, the sound of the EcoBoost is still stifled quite a bit. In fact, actual noise increases over the stock exhaust setup are minimal and nearly unidentifiable.

We needed to make some modifications to create a more prominent sound. Back
