Pt. 1, R5 Efficiency Test @0:00 Test 1 Prep @1:07 Test 1 Start - Stock Core Brass SFR Halfway +/- @8:31 Test 2 Intro @10:44 Swap Brass SFR to SS SFR; Easy with ‘Modified’ R5 Frame @11:33 Test 2 Prep @14:45 Test 2 Start - Stock Core, SS SFR Halfway +/- @22:44 Test 3 Intro @23:25 Install Method Tune-Up Kit @25:06 Test 3 Start - Tune-Up Kit, SS SFR Halfway +/- @38:09 Test 4 Intro @39:23 Test 4 Prep @43:43 Test 4 Start - Vortex Core, SS SFR Halfway +/- @50:44 Test 5 Start - CS3 Pro @57:52 Bonus - CS3 Pro + DRV Uncapped Question: 1. Is there a change in FPS and/or efficiency when using the Brass SFR vs SS SFR? 2. Is there an FPS increase when using the Method Tune-Up Kit or Vortex Core? 2. If there is an FPS increase, over OEM options, is there also an increase in efficiency when using the Method Tune-Up Kit? 4. If there is an FPS increase, over OEM options, is there also an increase in efficiency when using the Vortex Core? Equipment: Planet Eclipse R5; S63 Barrel - Bored to Match Paint Powerhouse Reg (600 psi output) AlphaAir 77ci HK Level 4 Paint (to be as consistent as possible among future tests, I’m choosing a good quality and readily available paint over 'tournament-level' paint Notes: New batteries in loader and marker Critical dynamic bolt orings on the stock core were changed prior to testing. By critical, I mean those most prone to failure in my experience. These are the 017 and 018 on the can, as well as the 14x2 on the bolt. Internal 008 HPR oring was changed prior to testing. Bolt and HPR is lubed prior to testing Bolt is re-lubed between each test. HPR is NOT re-lubed, so as to show any possible direct FPS changes from variables being tested Tank will be refilled and cooled before filling again, to allow a true ‘cold’ 4500psi fill. Goal is 10º within ambient temperature Steps: 1. Marker will be chrono’d on camera at start of each test (Variable 1,2,3, etc.). Chrono goal is average of 290fps. This is due to many tournament players chrono'ing a margin under the speed limit of 300fps; and some fields only allowing 280fps. 290 is a good middle ground. 2. Hardest part of test is deciding when to stop the test. Most efficiency tests cease when they see visible drop off. This is often correlated with a chrono of around 270-280fps, when shooting single-shots *A critical failure (leak/electronics, etc) will result in immediate stopping and restarting of that test Analysis: No barrel breaks/chops or critical failures were encountered during testing. As stated, most difficult portion is when to cease test. It would be more accurate to have an electronic system linked to a chrono, which actuates firing until the avg of the last 5-10 shots drops below 280; otherwise you're relying on sight/feel to determine; which itself is subject to Least Noticeable Difference complications. Results: (1) Stock Core with Brass SFR (Halfway +/-) Shots: 1350 (2) Stock Core with SS SFR (Halfway +/-) Shots: 1231 + 24 (24 shots were taken before remembering to reset the counter) = 1255 (3) Tune-Up Kit with SS SFR (Halfway +/-) ~20fps increase over Test 2 Shots: 1138 (pushed the test to 1168 to be sure I visualized drop off) (4) Vortex Core with SS SFR (Halfway +/-) ~20fps increase over Test 3 Shots: 1245 (5) CS3 Pro Shots: 1385
