Boss 182™ – Lycoming IO-580 Engine Conversion by Wipaire

Are you ready to fly like a Boss?

If you’re feeling uninspired by the performance of your 182S or T, or maybe your IO-540 is nearing TBO, it’s time to consider the Boss 182™ engine conversion by Wipaire. Our Lycoming IO-580 engine conversion is the most powerful factory-new option available. With 315 hp stock, and up to 340 hp after engine tuning by Ly-Con, your 182 will fly like a whole new airplane.

What’s included in the conversion?

Everything required to put a silly grin on your face every time you push the throttle forward. That means our high-flow tuned exhaust that adds effective horsepower, a variety of propeller options to muscle you into the air, and a firewall beef-up to give you a gross weight increase are all part of the conversion. If you’re on floats or thinking of converting to floats, we offer a heavy-duty seaplane engine mount. The Boss 182 engine conversion is the only late-model engine upgrade approved on floats!

On wheels, you’ll enjoy a gross weight increase to 3,158 lbs. On floats, gross weight increases to 3,370 lbs or 3,500 lbs are available. Climb rates of up to 1,400 fpm (50% greater than stock!) and increased cruise speeds are other benefits you’ll take advantage of with a Boss 182 conversion.

The Boss 182 engine conversion is available for the Cessna 182S and 182T models in both landplane and floatplane configurations.

Fully Loaded” VS “Typical Load” Performance Data: For FAA certification of new modifications Wipaire performs extensive performance tests with the aircraft loaded to gross weight. This certification data represents the minimum performance expected out of an aircraft loaded to maximum gross weight. In order to better represent the level of performance most pilots will see we are providing performance specs taken with a “typical load” of pilot, co-pilot, 60 gallons of fuel and testing instrumentation. This gave us a weight of 2,839 lbs.

Feedback From the Field

“My favorite feature on wheels is its inherent stability and ground handling. On floats it’s amazing. It comes off the water really sharp. You don’t ever have to wonder ‘at what point will it fly,’ it just gets on step and goes.

I highly recommend the Boss 182, and I recommend it whether you’re going to put it on fat tires, float it, or leave wheel pants on it.”

– M. Holt, Boss 182 Owner & Operator
