    Tested the new R&D RXP-X Grate

    We took a customer's bone stock RXP-X with 5 hours on it and ran it with the stock grate and got 68.8mph on the stalker radar gun. I'm sure once fully broken in it will be closer to 70, but for now we got 68.8mph. Then we swapped the stock grate for the new R&D. We got 72.4mph, a gain of 3.6mph!!!!! R&D claims 3mph gain, so we're very happy.

    We still haven't had a chance to test the RXT-X grate from R&D yet as we don't have one here to test on. Any guinea pigs want one locally at dealer cost to let us test it on your ski??? Give me a shout

    Did you notice a difference is acceleration/hook-up?

    We dropped the ski in the water in North Miami's Snake Creek. Warmed up for 5 minutes then tested on the stock grate. Then pulled the ski onto the trailer and swapped grates. Put the ski in the water, warmed it up again for 5 minutes (probably didn't need to, but we wanted to test consistently), then ran it again. Same exact conditions and water. I was quite impressed. We'll try the 15/20 Skat 3 blade and the Solas 15/20, and 15/22R next....still leaving everything else besides the grate stock.

    The acceleration was the same and hook up/handling was excellent....although testing was on flat water, so we can't attest to rough water hook-up yet.

    Will do. Still waiting for someone with an RXT-X to come and test the grate as well.

    Is there any danger of the "buck" when using the R&D grate at that speed. There have been multiple reports of people being thrown when they modded the intake.

    Well, we haven't reached the speed where they start bucking, but according to R&D's tester, they do not buck with this grate. As we keep adding mods to this ski, we will report any results....good or bad, with these grates....but so far so good.
