We purchased the velocity stack from Macsboost for our 21 Superjet! We also purchased the one from Riva! We went to the water with 2 different 21 Superjets both set up very similarly. We switched between the Riva, the Macsboost and what appeared to be the Riva filter without the elbow tube. I will tell you that both riders felt the Macsboost had more from top to bottom on both skis. One of the skis had an RPM gauge on it and the Macsboost velocity stack allowed that ski to rev 200 rpm higher than the others confirming that what the rider’s were feeling was true!
