MACSBOOST’s Raising the BAR for Air Intakes on Yamaha Supercharged Watercrafts

What If we told you that you could install an extra 200RPM using a screwdriver and 5 minutes of your time? Would you do it? What if we told you this was the gain OVER an existing “high performance” intake on a stock class race ski?

The 2019 FX-SVHO Test Mule, Specially prepared for stock class racing.

Is it Impossible? Could this be fake news?

Our preliminary testing on a 2019 FX SVHO stock prepared race craft with stock intercooler showed a back to back increase of 9100RPM to 9300RPM going from another high performance intake to our exclusive MACSBOOST Velocity Stack Air Intake. Top speed was a blistering 82.5mph

Obviously, your performance may vary, but the increase could be even more dramatic on more highly modified skis. It should also be noted that a performance tune is required to get the full benefit. Stock tunes often work against high performance modifications such as this.
