Mark sullens E85 Story
A Family Business Fueled by E85
We began developing E85 carburetors in 2002 after forming a partnership with the National Ethanol Vehicle Coalition. At the time, E85 was opening new doors in racing making competition more affordable and creating fresh opportunities for performance development. Those early years were spent working closely within the industry alongside other carburetor builders, while steadily refining our own approach to E85 technology.
From the very beginning, this has been a family effort. None of this would be possible without the unwavering support of my wife, Tana, who has stood beside me through the long hours, the trial-and-error, and the growth of this business. Our shop is more than a workplace, it’s a family. The people who work here aren’t just employees; they’re part of the team that makes this operation run, day in and day out, because we all believe in the work we’re doing.
Our focus has always been on continuous improvement. Rather than offering a one-size-fits-all calibration, we committed ourselves to refining performance, consistency, and reliability to meet the demands of serious racers. Every carburetor we build or convert reflects that mindset, attention to detail, proven methods, and a refusal to cut corners.
Over the years, our customers have gone on to win multiple world championships, and their success is something we take great pride in. Those wins represent more than trophies, they reflect trust, hard work, and a shared commitment to doing things the right way.
When we tell you something about E85, the information we're telling you is based off YEARS of personal experience from both our own research and development or the feedback from our customers.
We strive to deliver the highest level of excellence in both our products and customer service. While we may not be the lowest-priced option, we believe strongly in providing lasting value and proven performance. Investing in quality from the start helps ensure reliability, consistency, and long-term success.
This business exists because we love what we do. Racing, building, refining, and supporting our customers isn’t just our job, it’s our passion.
Thank you for visiting our page. We look forward to working with you and helping take your performance to the next level.

Two People. One Vision. A Lasting Legacy
From the shop to Niagara Falls (above photo) Mark and Tana proudly represent the passion, dedication, and legacy behind MSE85 Carburetors. Behind every carburetor, every phone call, and every custom build are two people who have dedicated their lives to the performance community:
What started as a passion for racing, engines, and helping fellow enthusiasts has grown into MSE85 Carburetors, a business built on trust, craftsmanship, and genuine relationships. Together, Mark and Tana have spent years supporting customers across the country, turning horsepower goals into reality while treating every customer like family.
Their journey has never been just about building carburetors. It's about building something that lasts. A reputation for honesty. A commitment to quality. A willingness to share knowledge and help others succeed.
Whether they're in the shop, at the track, traveling the country, or representing MSE85 wherever life takes them, Mark and Tana carry the same values that built this business from the ground up: hard work, integrity, and a passion for American performance.
Today, MSE85 stands as more than a company. It represents decades of experience, dedication, and a shared dream. Every carburetor that leaves the shop reflects the standards they have spent years perfecting and the legacy they continue to build together.
The greatest achievement isn't the carburetors they've built. It's the community they've created, the friendships they've made, and the impact they'll leave on the performance world for generations to come.
