12/14 Petschke Motorsports dyno testing the ETEC 800 with their new flowbench tested Y pipe results posted on this website members' pages
12/15 Keith Monroe, F7 w/ D&D trailport dissapointing performance last season was traced to a counterfeit BMP pipe modded stock pipe that Keith had bought on EBay. I was leery since the counterfeit pipe had poor welds, and my suspicions were confirmed when we installed the BMP modded stock pipe I have here for test purposes and picked up 13hp.
12/17 John Joyce,Wayne Yeardon, Rob Schooping testing Merc 440 freeair oval racer- Rob is back at his home shop now, back to his roots modifying/ porting engines. Since the Merc 440 piston port engines are similar to the powerful 650 Polaris triple engines Rob created back in the 1990s, these are a natural...
12/21 the worst day of testing ever--two sleds with freshly rebuilt engines, freshly installed back in the sleds with what appear to be air locked oil pumps...no premix in the gas, sled 1 (a big bore twin) locked up just before we began the test, at 12/1 A/F...a disappointing mystery but that can happen...then sled 2 made one pass loaded with fuel, then locked up like sled 1...autopsied that sled on the dyno, the bottom end was bone dry totally devoid of any sign of oil! Sled 1 was autopsied back home, bone dry like sled 2. Moral of this unhappy story is, whenever an engine is removed, then reinstalled, the first one or two tanks of gas should be premixed. They will be back, with slippery fuel in the tanks next time!
