WIENANDT Performance Technology (WPT) is owned and operated by Mike Wienandt who has worked in the engine performance industry since 1977.  WPT is a High Performance Shop that specializes in custom preparation of engines and development projects specifically designed to meet customer needs.  We do not generally repair engines or do general consumer engine work.  Rather, WPT is a specialty race shop, working for established race teams and OEM consulting. Contracts with “non-discloser agreements” are common in our performance work. The scope of work includes the following:  complete machine shop, grinding area, layout and inspection, three levels of wash tanks, assembly area, two dynamometers, flow bench testing, and ignition testing with oscilloscopes. Mike and WPT can offer you consulting services with the most advanced computer engine modeling software in the world.  Additional custom work and manufacturing are also within the scope of our services. And what about our success: We have more National and World titles than any other shop in the United States. In short, WIENANDT Performance Technology can provide for you the TLC that few other high performance centers can even consider.

     It is a small family business that brings great pride to Mike and Kim Wienandt.  Mike manages all design and development operations.  All finish porting and machining is done personally by Mike.

     Jonathon Wienandt, a student at Moraine Park Technical College in pursuit of an Associate’s Degree in Engine Design and Development adds a great deal to the operation.  Jon is the chief Dyno Technician and has many other duties in engine building at WPT.  Jon travels with me in the summer time and works for two of the boat racing teams we support.

     We work in the shop only evenings and weekends and Mike, Kim and Jon all work at Mercury Marine during the day.  We travel many different racing circuits to stay in touch with our products in the field. Summer time it’s boat races and winter we attend snowmobile races. We are always available at any race we attend for consulting.  We need you to know the information you need to be successful.

     Mike is a 34 year veteran of the American Power Boat Association where he is has been everything and held many titles. Mike has been a driver/owner in the Stock, Mod, Pro and OPC outboard categories for 26 years. Along with working as a race official, Mike has worked as Race Director, Referee, and Inspector.  Held national office titles of a Commissioner in three categories, Technical Committee Chairman, Category Chairman as well as being a past Board of Directors member.

     Mike has been involved in Snowmobile racing since 1977.  He also has been a member of the United States Snowmobile Association since 1979 and has held many positions there as well.
