Monday, Kevin Freeman driving in from The Sled Shop in Presque Isle ME. Mach Z trail ported. CS twin pipes, Boondocker to dial in. Boondockered this Sled Shop trail sled to a safe 192 CHP at close to .70 lb/hphr, 125 lb/hr fuel flow on top end. also Boondockered out a vicious midrange .45-.47 lean spot at 50-70mph cruise. now it’s dandily safe everywhere.
Tuesday Randy Haulman back again with revised nitrous oxide plumbing on his SkiDoo, new plumbing = good HP easily made 200 plus before cylinder ran low of liquid in his Boss Noss setup– and that F7/F8 should be here for tuning this time this F8 was done by Racin Station and has excellent airflow and HP, picked up 8 HP with Bikeman pipe mod to boot. Also in PM a Canadian lakeracer F7 for tuning Craig’s F7 trail port was done by Iantamassi (sorry about spelling) made dandy CFM and HP, also picked up 8 HP with Bikeman pipe mod, could have used Boondocker but we were able to get by with tweaking fuel pressure.
Wedneday Tim Ellis with a lake racer mod 1000cc TCat.150 psi compression, 44megatrons, D&D trail pipes = 218 CHP, Tim had a dynosheet on this engine from Anoka-Ramsey’s SF901 dyno 220 CHP close enough.
Thurs-Tues off on ill-timed vacation to FL.
Wednesday 2/1 am Bikeman trail port single pipe F7.SnapOn Dick’s F7 was surely one of the best, with BM pipe mod DDY and BM trail port, Boondockered on pump gas three Horsepower settings 161, 157, 154 (the last = Canadian trail setting .70+ lb/hphr)
Thursday 2/2 9am a stock Mach Z and CS pipes to be Boondocker tuned Mike’s bone stocker w/ 05 map, CS domes wound up with three Boondocker HP settings, 192, 188, and 185. 11am a MXZ700 w/ mcDizzy ultra midrange package. we jetted, tweaked different reeds/ boost bottle combos made nearly 140hp, about 20 more than stock. 2PM a Union Bay Polaris 900 billet cylinder twin with SLP twin pipes,
plan on testing pump gas and race gas domes (tentative–confirm on Wed) Rescheduled for Sat AM 2/ 4/06… dyno’d Sat AM, on race gas 182 HP with timing and jetting optimized, pump gas made 178 HP, Friday 2/3 AM Jeff J’s homebrew trailport F7, 010″ off head, 2.5 deg key, Boondocker, new Bikeman stamped pipe (clone of modded stock pipe?).Jeff’s was another good one, but it took our BM mod stock single to reach potential of 158 HP, 154HP and 151HP (three Boondocker pump gas settings). Jeff’s first Bikeman stamped clone pipe split the difference between bone stock single and BM mod single. Also a new DDYpipe added zero to this particular combo.
