Just tested the Riva power filter and free flow exhaust
The results were extremely impressive. The difference in acceleration and throttle response was HUGE! The ski just snaps right out of the hole like a slingshot.
Top speed bone stock was 66.8 mph with 4 bars of fuel.
With only the additon of these two mods the ski ran 68.4 mph (same amount of fuel)
Those that have been following my posts know i installed a boost gauge. Boost was at 7.0 psi. I spoke with Yamaha reps months ago and they told me stock boost was 5.5 psi so i basically saw a 1.5 psi improvement from the addition of the air intake. This is typicly what we see on the Sea Doo's when going with a freer flowing air intake.
I can't wait to install the rest of the components of the RPM kit. The grate and ride plate are going to bring on more speed

I take it that you could really feel the difference? Pulls much harder?
