Just got done Intalling Riva,s power filter looks like a nice produce, will see what the gps shows.

TOOK SKI OUT TODAY WITH POWER FILTER ON IT HAD EVEN BETTER ACCELERATION,TOP SPEED DIDNT INCREASE BECAUSE I THINK IT WAS HITTING THE REV LIMITER AT8100 RPM,S.NOW WE NEED RIVA TO COME UP WITH A PROP FOR US,LIKE REAL SOON.

Here in Pa.where at elev. 100'temp has 80 deg.humt.was75%. THE reason I tought I hit the rev. limit I could hit 8100rpm's trimed all the way in or out it didnt matter and I have hit 8100 be fore the mod.I also tryed a 2.5 wedge Iam getting .5deg. machined out it handled real bad even with a work,s intake grate.

Rancart, I've seen a Riva post that said the wedge is designed to be used with Riva's intake grate.

Yes voodoo Idid read the posting this maybe the case. But Riva's isnt aviable yet.

if im not mistaken i read a post somewhere,,where R.C. said they were not using the wedge at all anymore!!!!
DONT QUOTE ME ON THIS I MAY BE WRONG

Jarrett,
Do you have a plan for a baseline before you do the install? I'd be interested in what you see as a difference.

What I would like to see would be RPM before and after. GPS would be nice.

Please tell your friend, his friend and his friend's friend that we're still recommending our 2-degree pump wedge for our Stage I Kit. Thanks!

Jarrett, since your local weather (Texas) is so similar to the one at rivas in (Florida) your test should be the perfect example to back up rivas claim of 4 to 5mph increase with this incredible low price stage 1 kit, if everything goes well Mr. Glenn Perry from (PPG) it's goin to the crying for a very long time, trust me Ray

My friend has GTX SC. We installed R @ Ds full kit on it. We found that with pump wedge the ski would not turn at all. We took it off. The ski ran lean with the filter on it. <would die running wide open> We took it off. In those early pictures of the kits I saw a fuel controler. R @ Ds kit needs one. Before the boat would die it was flying. As they all do before they make those funny noises.

u better hope that 4tec doesnt make any of those "funny noises".

oh my lord, run it lean under boost...

I did a plug check on my rxp light gray to white very scary, havent done a check since powerfilter! I also remove the wedge having some of the angle removed.

Ray, if I get 5 MPH out of this thing, I will dance the jig Really I'm just expecting 1-2 MPH and hopefully some holeshot.

Jarret, if you get 5mph more with this kit I'm buying too. I hope their claims isnt BS!!!

This is the reason we recommend you use our Top-Loader Intake Grate in conjunction with our 2-degree Pump Wedge.

For now that problem is eliminated with an aftermarket impeller. Which also helps prevent you from hitting the rev limiter.

Just an FYI - we just completed another series of tests with our Sea•Doo EFI Control Unit development and it works great! A few little tweaks to the settings and dials and we should be able to give the ok for production units. Of course that's easier typed than done with the proper approvals, paperwork requirements, etc. I'll be sure to post when we have a more solid date. Stage II (and III)......here we come!!!!

rancart, Was your plug read with the R&D or the
Riva, and if Riva, was the cover installed. I
have heard the r&d run lean, but no test on the Riva I have on order. I'm in Las Vegas and run on Lake Mead, 100 to 110 degrees now with about 10 percent humidity. RPM with chop about 7750.
Have R&D grate, Works sponsons down. Terry

It was stock when plugs were read than I istalled filter with cover but I didnt get a chance to read them. Where going out thrusday Ill check them than.

Riva crew, R @ Ds kit does have a intake grate and prop. However there filter is quite a bit different than yours. Lost the rear storage compartment because the filter is in the rear of the motor.

Start to finish 1.5 hours. its a little tricky
mounting the bracket that holds toob by air filter.
I dont have a prop yet, so I havent been running
up top to long.
