11/9 private session cams off
11/12 private session cams off
11/13 Jeff Stinson trail mod F7.another perfect Boondocker tune, 13/1 up to 7200 valve opening then exactly flat 11.5/1 from 7201 to 8200.. PM Apex w/ Bender muffler PCIII found bigger HP with a combo of modded airbox and added fuel (a must) with PCIII
11/15 late AM Dave Shoupe HTG Fusion, new twin pipes tried a set of twin pipes with boondocker, made less HP, tried SLP pipe/ can but finally back to HTG single pipe and can for best TQ/HP
11/17 Greg Whitney (Nova Scotia) F7 w/ F1000 engine Madman Greg drove 1200 miles to get a perfect tune and bring me 12 Molson XXXs and get a perfect trail tune, beautiful installation, bone stock engine 190 plus with SW Ypipe, pipe, and can and 185 plus at ultra-safe 10.5/1 for upnord mystery pump gas.. PM Bill Swartz SDI600 mod Crankshop trail ported cylinders, CS single with stock muffler, boondocker tuned to 135 HP with no deto, all in a 440 snocross chassis…
11/18 CJ Motorsports, Full Power new production 4tek1200 stock baseline then install production turbo kit on the dyno, check fuel mgr calibration seemingly tighter stock muffler created deto on 87 that wasn’t there on preproduction machine, so tuning tuning tuning finally have pump gas stage 1 and stage 2 packages 200-240 HP and race gas easily to 300 plus.
11/21 AM Joe Parfitt, Mach Z tuning NX N2O learned something new today from Sled Shop Joe (Baldwinsville NY) like we do every day, those NX Y shaped nozzles are limited in N2O flow just like we sort of figured with Tony Koz’ big Cat twin. Also Joe’s MachZ may have been suffering from maladjusted exhaust valves, and that light pressure EFI pump with the wet system was creating severe on-button deto until pressure caught up with N2O, engine saved thanks to Sean Ray’s detophones. But with Joe pushing the N2O button and swapping jets he’s got a dandy lakeracer with 260 plus at .60 plus total BSFC (measured fuel flow from EFI plus fuel flow from wet system) the way we like it.
11/22 Ron Schantz and pals, two or three big Cat triples more Canadian madmen lakeracers with green thong underwear…learned lots today by swapping many sets of big cat triple pipes/ mufflers/ CDIs with three engines— Ron was off 80HP on his sled because he was told to run 9200 when his HP really happened at 8500 Dont believe anyone, test your stuff on any instrumented dyno to be sure..
11/24 AM Mike Brisbane, F7/8 BMP with N2O, mike wanted pump gas power with an extra shot of pump gas nitrous, but we tweaked and tuned on his NA baseline but the detophones were warning of nasty midrange deto even with normally safe fuel flow and A/F ratio, it was rattling the detometer so hard NA I advised leaving the N2O for another day…he must check installed uncorrected compression ratio. N2O and big HP on pump gas is difficult, and if were clicking NA we must change something before we destroy parts.
11/25 private session all day, cams off
11/28 Jason Pigeon F7 mod Cat radar runner, deeder cancelled, maybe another mystery cat coming in PM…Jason was fibbing, actually F8 tuning for radar running with D&D Monster Single jacked timing and fuel flow with High RPM D&D Boondocker to over 180 HP.
