Recap from last night. We did pretty good in our heat fumbled the start lost a couple spots but held on to make the redraw. Pulled a 8 pill so that was sweet. But unfortunately we are chasing an over heating issue. We were at 250 degrees before the green flag in the feature so we pulled off to save this motor. We will try and find something this week maybe it’s something simple.

It’s RACEDAY!

Tonight we will be at I-90 Speedway. Got some rain yesterday but looks like it might turn out to be a pretty good night. A little chilly later so bring a coat. Second week with the back up motor. Think we got all the bugs worked out so see how it goes. Thanks to all these great people who get us on the track every week!

After the new motor was tore apart I got these pictures of #2 cylinder. That’s not ideal. Good thing I bought a back up motor. Hopefully we can get this one back this year yet. The way she goes sometimes.

Just an update here on last Saturday. It was our first race of the year with our brand new set up. New car and brand new motor. The car was fast in the heat. It was so much fun. Went out for the feature and had a red flag not even one lap in. Got pushed off and restarted m, well the car started smoking. Then the rain set in which canceled the race. I didn’t know it was smoking as you can’t see it inside the car. After investigation, piston #2 decided to leave the party. We burned the piston and in return may have messed up the cylinder. So we are goin to dig into it alittle more but I got a good local motor that we are interested in. We are goin to miss this weekend as I don’t want to rush and forget something then be right back in the same spot. But we will be back next week. It sucks but unfortunately this is part of racing. Was just hoping to get some more out of this new motor. We will be back soon.
