Monday 3/6 AM more testing on yamaha motoctross bike w/ aftermarket silencer.
Mon 3/13 nothing scheduled from here on out. Jimmy Cooper planning to stage tune a sdi600 this time with lower compression and added timimg plus we can dial in the Skidoo sdi600 shootout sled box.
Monday 3/13 dyno tuned F7 and F6–extensive tweaking multiple keys multiple heads multiple ECUs fine tuning fuel flow with restrictors. Cameras off because 1) sled owner didn’t want his competitors watching. and 2) something’s amiss with building phone/ internet service. Sleds were from the twin city area of Minnesota.
Wednesday 3/15 9am a Big Moose lakeracer coming down for late season tuning, no cameras again (option of dyno customer). got this one dialed in, fixed an awful lean midrange, fattened a lean overrev A/F ratio, determined HP peak at 3, 6 and 12 seconds to enable proper clutching for the lake Saturday. 11am hoping cameras are fixed by then, Greg Bennett back with his turbo Polaris twin lakeracer, model 66 Aerodyne turbo with very custom mountain motor cast cylinders from HTG (Rob Schooping created a gonzo HP low port XLT 10 years ago, applying that experience to these 990cc cylinders). 116 octane gas, unlimited boost pressure. My armpits are beginning to moisten. rightfully so, nearly 200 lb/ft torque on my standard 1.25″ OD driveshaft (my more correct large shaft would not fit bellypan) 296 CHP but EGTs are moon-high with safe mixture, indicating this engine may need more advanced timing, left it on the dyno, THURSDAY AM try an ECU with added advance, must have 300+ to try to keep up with the Big Moose Lake madmen this Saturday, hoping to have morning 300 champagne.
Thursday cameras will be rolling again, expecting something to observe soon.Thurs AM my armpits are still wet, 1.25″ tube shaft held 204.7 lb/ft of torque EGTs are comfortably low thanks to custom Wahl Bros ECU for turbo, will try to post dyno numbers this weekend.
