how amny hours on the motor ? nic motors take a while to break in . im not talking milage but actual time. also was this a track dyno or a motor dyno? makes a big difference.
We did the test acouple of times. The temp were cheched many times. When it got 80C it started to lose power, I got 125hp, then we let it cool of and I got 132hp. The test was done 5 times. I think they were going to dyno another F7 this week, if that snowmobile get 138hp I`m going back to the dealer. To see if there is any problem with mine.Originally posted by f-5snopro@Dec 10 2002, 09:28 AM
did they give you the dyno sheet? there are so many variables that come into play when dynoing a motor . air temp,fuel temp , jetting, engine temp, pipe temp, the dyno itself, actual fuel octane not the pump rating, ect ect ect.................... i would not worry to much about it . i think you stated it made 132 hp and thats only 6 hp off the 138 mark. hp can be achieved with proper tuning and with changing other variables that come into play when dynoing an engine.
