Thanks for the 411
Late model rare, limited build, race and/or muscle sleds are my deal!

Only 6" at the moment but supposed to be below zero for the next week and a half so I am pretty sure that the ice will be 15"+ and be a safe event.  Waconia should be just fine as well.  Was nervous for a bit and still am a little bit.   But it keeps on looking better all the time.

Here is a video of the final run on our first day out with the 440.  We found out we were almost out of fuel as you can hear the studder at the end of the track.  Started the day with 2 gallons of fuel in the tank and 5 runs later it was hlf gone and leaving the pickup sucking air on the last run.  Overall, very satisfied with how it ran but we didn't have light enough weights so we were running 2000rpm lower than were we need to be.  That is in our clutching which we think we have figured out for the next weekend.  Pretty excited where we are and where we are heading.

Not much for updates at the moment.  The first two times we were out was a bust as our tach was getting over voltage and would go from 8000 rpm back down to 6000 rpm and we didnt catch it until we started to question why every clutch change we made the sled ran the same speed. 

Since we found the tach error, all the events have been cancelled so we have not had a chance to tune it now that we arent spinning it at 11000 rpm.  Should be good numbers as we ran 94mph spinning it way too fast and the hp drops very fast after 10000.

Will post more if i get the chance to test a bit more yet this season
