At M&D Repair, a truck repair shop based in the heart of a farming community in Napoleon, Ohio, excellence in service and quality work are at the forefront of their operations. Founded as a branch of a successful popcorn farm, M&D Repair evolved into a trusted local repair shop, taking on more outside clients as the business expanded. Jon Haller, a lead mechanic at M&D Repair, has been with the company for several years, providing valuable insights into the benefits of using Switchblade Turbochargers.

What benefits have you seen?

One of the most significant advantages Jon and his team have experienced with Switchblade Turbochargers is increased fuel efficiency. They reported improvements in gas mileage, with their CAT 3400 series engine going from 6 MPG to 6.5 MPG and their Cummins X15 Performance Series engine jumping from 5 MPG to 7.1 MPG. These gains are substantial in an industry where every gallon counts. However, it wasn't just the fuel efficiency that impressed Jon and his team. The quick response and excellent customer service provided by the Switchblade team were equally valuable. When a client experienced an issue with one of their Switchblade Turbochargers, the M&D Repair team contacted the Switchblade office, and within days, the part was tested, and a solution was found. This rapid turnaround exceeded their expectations and solidified their trust in the product.

In my own words...

"When we first heard about Switchblade, it was from a trusted source, and we knew they had a reputation for quality," Jon said. "I tried about every other turbo on the market, but the results we’ve seen with the Switchblade regarding fuel efficiency are incredible. But what really stands out is the customer service. They get back to us quickly and ensure we're cared for. It’s hard to find that level of support in this industry. I’m only buying Switchblade from now on out."


As M&D continues to grow, Jon and his team believe that the consistent quality and customer service they receive from Switchblade will play a crucial role in their ongoing success.

Wake Your Engine Up While Saving On Fuel

In December 2014, Jim Blaylock’s crew @ Blaylock Turbo converted our truck with a C15 Acert Cat engine to their Big Daddy Switchblade turbo.

The first thing we noticed was a more boost and quicker boost. The Switchblade spools up like a turbo half the size; then the single vane opens up to a large turbo size.

With the Switchblade turbo, I no longer have to down-shift on the same grades I had to drop two or three gears on previously.

What benefits have you seen?

After approximately a month, when the owner calculated fuel mileage it went from 5 mpg to 7.28. We run 120K miles a year with this truck, and the owner estimates at $3.00 diesel, he will save over $20,000.00 in fuel annually on this truck alone. This is on top of turning the fuel up 100hp!

In my own words...

I would recommend the Blaylock Switchblade if you want more power and to save fuel costs while waking your engine up like you have never seen it before.

Trust in Switchblade for 18+ Years

I first met Jim Blaylock about 18 years ago via print (remember that?) advertising, and I have been a dedicated Switchblade Turbo user and proponent ever since. 

What benefits have you seen?

Before I got the Switchblade Turbo on my 3 older rigs, my oil change recommendation was every 125 hours, but I often needed to do it early, at around 109 hours, to ensure things kept running smoothly. After the Switchblade, it has brought it up to 200 hours, no questions asked. Not only that, but the black smoke on all of my rigs has reduced immensely. Other benefits are a much higher boost pressure, the ability to haul heavier loads, and best of all - improved gas mileage.

In my own words...

I love it. This thing pulls everything I have down the road. Has a cleaner look; it's just beautiful.

I installed a Switchblade® on my 3406B CAT Engine and now I'm getting 5.9 mpg compared to 4.1

What benefits have you seen?

Black smoke out of the stack was eliminated, and the truck has never run better - more boost and power. 

In my own words...

I installed a Switchblade® on my ‘93 Peterbilt 3406B CAT Engine and now I'm getting 5.9 mpg compared to 4.1! I'm saving thousands of dollars and am going to upgrade my entire fleet to a Switchblade® Turbo.
