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.
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
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
6'3" 200lbs (myself)
Test performed with 1/2 tank of fuel (approx 6-7 gals)
78-80 degrees (1.5 hr period)
Wind 6-8 mph
Brackish water (mostly salt/fresh mixed)
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.

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.
