Riva Ride Plates and Intake Grates-Any Good?
AutoNthusd
I was thinking of adding a Riva "Groovy" ride plate and bi-loader intake
grate to my completely stock '95 WaveVenture and was wondering what
experience anyone has with these two Riva products.. Riva claims better
hook-up, better acceleration and slight top speed increase, any thoughts?
Thanks for your advice.

Riva Intake grate is a waste of fucken time. Total loss of top end in the
region of 4 mph and no diff. in terms of cavitation or any other "out-of-hole"
improvement. Possibly a slight improvement in choppy ocean conditions. The
Rive rideplate def. improved straight line stability and cornering, especially
when towing a skier. Riva also totally brain-dead when it comes to e-mailing
them for assistance.

If you installed in on a 701 Raider you'd notice a big difference. I
put that and the quick turn nozzle on my Raider and gained over 1 MPH.

I think you must have another problem if you lost that kind of speed?
I race a blaster and have tried several different intakes, ride plates and
props, I currently have a riva plate and a jet dynamics intake. I personally
think that the hype over jet dynamics is all BULLSHIT. This intake cost 3
times what anyone else intake cost and I would gladly take a riva tri loader
in exchange. The last riva intake I had, there was no lost in speed and if
anything it gain speed because the pump would stay hooked up, I even think it
performed better in the corners, but I guess it depends on the boat.

Ummm, the Riva Groovy plate for the 701 is *shorter* than the stock plate.
I get better wave jumps because with the shorter plate the boat goes vertical
much easier.
Ultrac doesn't make Magna Flows for Raiders.

This is true. However we do make the Magna-Flow for the VXR, SuperJet,
Blaster 1 and Blaster 2. We have not made the Magna-Flow for the Raider at
this time because most people choose to go to Riva, Pro-Tec. Frankly, as a
consumer, I would probably go to these companies too, but ironically we
have a better mousetrap on these particular vessels.
I would have promoted this grate to Yamaha dealers, but the general
consensus is if you don't specialize in a certain type of craft... you
will not be the best. So we concentrated our efforts where we found
support... with Sea Doo dealers and enthusiasts.
On the original question regarding Riva's Ride Plates and Intake Grates...
far be it for me to pass judgement on another manufacturer, but...
1. The Riva intake grate does not work well. :-(
2. The Groovey Ride Plate (originally developed by Tony Doukas and
knocked-off by Riva) does work well. :-)

would be going 100mph. Don't believe it, especially with Riva, there not
reputable enough. Very few companies have a reputation for being honest in
there marketing claims, a couple I know of are; Factory pipe and Group K.

I'd like to clarify this statement. The preceding statements were made
after testing the Jet Dynamics, RIVA, R&D, and ULTRAC Magna-Flow on a
Mod-Blaster. (actually, a RIVA Mod) We also tested the Jet Dynamics Ride
Plate, the Groovy, and Pro-Tec's Plate. The Groovy definately held the bow
down, and reduced porpoising, but was more skittish in cornering and
caused the hull to broach slightly. The Jet Dynamics worked well in the
corners, but did not provide good lift coming on plane and allowed
porpoising to commence easily. (my weight at the time was 190, therefore
the results would be different with a lighter rider) The Pro-Tec ride
plate worked better than the stock plate, but was not all that pronounced.
I believe they have a better plate available now.

Riva. Maybe *the* Yamaha stronghold. They don't want you taking sales away
from a key dealer.

Do you remember the conversation we had about this? Can't remember if it
was a phone conversation or net notes. If I recall correctly you stated that
the stock grate on the Raider minus the two inner bars was just about the
best grate design for the intake shape on the Raider (701). I'd be interested
in hearing that explanation again, don't know if I'm misremembering.

Yep, I love this plate. Raider tracks great with it. I thought Doukas had
a rougher version of the groovy used for racing (and hand made) and Riva made
a "mass production" quality (i.e. lower) grate. Like to hear this story too.

I don't know what I did with this post, and sometimes it's hard to re-call
(must be related to the 2nd hand smoke I enjoyed in high school!), But
your statement is correct. Actually, when I stated the RIVA grate does not
work well, it was based on testing with a Blaster. I never tried it on a
Raider, so I should not pass judgement, but based on the original post,
there is reason to beleive it may not work favorably on the Raider due to
the size of the intake housing.

I think your right. Tony tried took them to court, but I don't know what
came of it. I do know for a fact that RIVA knocked off Triton's Heads, and
appearently, Jet Dynamics threatened RIVA with legal action as well for so
closely emulating their Top-Loader. I think you already know that APE
licensed them on their pipe. (it is manufactured by a foundry for APE, but
private labeled for RIVA) and many of RIVA's original race porting specs
came from Tim Porter from ABLE Performance Products (remember the
cylinders Tim Judge used to win Havasu three year ago?)
That's all the laundry I know...
