back to back grate test for X?
Has anyone run a back to back test between a custom intake grate vs a R&D intake grate on the X models?

Riva or R&D?
I'd like to try an intake grate on my RXP-X. Which is the best? I guess a better question is what are the trade offs? I don't expect to loose the hole shot and expect 3 (?) MPH increase. How about handling, rough water, chop... Weeds??

My opinion as of late is to just cut the stock grate. When I get above 71mph consistantly, then I'll drill the holes up into the pump shoe to help relieve any excess pressure (prevent overstuff). A user on here "BeachBum" got the same gains as the R&D/Riva as far as top speed goes, but since the stock grate still has the large opening into the pump tunnel (the R&D and Riva close off some of the opening) he kept the holeshot/accelleration as well.
I've been waiting for some other's to chime in on several other threads relating to cutting the stock grate and their results, but that doesn't seem to be happening. I want to make purchases now/soon, but don't want to waste $$$. To me, accelleration/holeshot is as important as top speed... if not more so.

The stock cut intake grate is the best IMO, but you will need to solve the stuffing issue. I haven't seen anyone report on if drilling the holes and using the stock cut grate works.
Stock cut grate is FAST.

Here is R&D's Claim
RXP-X Aquavein Intake Grate
+3 MPH TOP SPEED GAIN
Nothing Outperforms An Aquavein
The new Sea-Doo X watercraft are by far the meanest production personal watercraft the world has ever seen. Itís got power, lots of power! But is it enough? Can it be even better? At R&D Performance, getting more power and better handling is what WE-DOO BEST! Bolt on the new X Pro Series Aquavein Intake Grate and put that 255 horsepower to work! R&Dís exclusive dual patented technology thatís incorporated into the revolutionary Aquavein will enhance the X beast. Blow through low and high-speed turns with confidence and chew up rough water conditions with a new found 3 mph top speed gain. Quicker acceleration and straight-line stability are also maximized. The new X Sea-Doo, equipped with an R&D Aquavein cracks the glass on the fun meter!
Pt. # 113-95004 RXP-X Aqauvein Intake Grate
Pt. # 113-95005 RXT-X Aqauvein Intake Grate
Now The RIVA's claim
RIVA RXP-X/RXT-X Top-Loader Intake Grate Our top-loader intake grate features a unique tapered wing design that eliminates prop spin and cavitation while delivering enhanced acceleration and 2mph additional top-speed. Deep side rails improve stability and handling. Durable black race coating protects from corrosion. Race Legal. Fits all RXP-X & RXT-X models.

Ive tested both grates, and with neither did I notice a loss in hole shot or acceleration. IMO, you will be ok with either, but dont use the reduction nozzle if you want to keep the above mentioned atributes.

I have run the stock cut grate (outer wings removed) at 78 mph with the holes drilled. IMO the R&D grate is the best, same performance as the riva but better hook up in chop.

I'm running the R&D intake grate on my X... I only had one chance to GPS it... I did 70.3 with a full tank of gas on a hot day with a little chop... to me the R&D grate is built stronger than the Riva one... the only thing i dont like about it, is that it doesn't comes in black...
