    Tested the 2nd SS grate

    I am sorry for taking so long, but finally caught a morning where the winds were not so high. Most days its been blowing 11-18mph with gusts 20-24mph. Not real safe for consistent high speed testing.

    Test
    Stock R&D 800 grate vs Greenhulk SS 800 grate
    Greenhulk SS grate was fresh out of the mold, so I had to do some minor cleaning and bolt hole alignment. I tried to make the grate identical to the R&D 800 grate for testing purposes.
    Both grates drilled to accept M8 mounting bolts.
    Installed with Grade 8 steel M8x30mm front bolts with SS washers and M8x12mm rear bolts no washers

    Craft
    My personal 04 EFI GPR1300
    Non-ported, VFIIIs, 150psi comp, big WFO keyway, elect PVs, DF14/24, Jim's FF plate, R&D trim tabs, Riva race filter, Riva Freeflow
    Custom Aluminum front intake grate mount
    Rear mount (shoe) drilled and taped to M8

    Rider/Conditions
    6'3" 200lbs (myself)
    Test performed with 1/2 tank of fuel (approx 6-7 gals)
    Mid-Superman position
    78-80 degrees (1.5 hr period)
    90-87% humidity
    Wind 6-8 mph
    Brackish water (mostly salt/fresh mixed)

    Results
    All testing was done in same direction
    R&D 800 grate installed
    1st pass 78.3 @ 7240
    2nd 78.5 @ 7230
    3rd 78.4 @ 7230
    Installed SS 800 grate and 2 gallons fuel
    1st pass 78.0 @ 7220
    2nd 78.3 @ 7230
    3rd 78.4 @ 7220
    4th 78.3 @ 7220
    Installed R&D 800 grate again
    1st 78.3 @ 7230
    2nd 78.4 @ 7220

    The Greenhulk SS grate performed almost identical to the R&D 800 grate. The SS grate seemed to cavitate less and hook-up better when pinned from a 20-30mph roll. Probably due to the thinner rear connecting bars. SS grate stayed hooked up slightly better in 6-8" chop. I was very pleased with the overall performance.

    Now THAT is some precise documentation crucial for accurate testing. Thanks for all of the info Rich. NOW I will order myself 2 or 3 of the grates. I may order an extra since these will be a "limited edition".

    Cool

    WFO, Glad you finally got to test the SS grate your test info looks as if the results were very similar to mine. The SS grate matches in performance to a stock R&D 800 grate. Take care , Tommy Jordan

    Thanks for the testing WFO.
    I hope this gets a bunch more sold, these SS grates need to become reality.
