Got out this past Sunday for an 1/8th mi shootout at my home track.
www.nyirp.com
This was a ‘Box’~’No-Box’ race only and had over 200cars, 6 sleds, and 8 bikes.
Got to the track and it was already 78deg, it was going to be a hot one…
Pulled the sled off the trailer and made my first run:
Time Trial Run 1: running at low boost, forgot to flip the switch… so, rpm was low, etc… (my fault)
1.46 60’ – 5.86 1/8 @ 118.82mph
Time Trial Run 2: Ran at high boost… (fastest ET & mph ever in the 1/8th)
1.44 60’ – 5.64 1/8 @ 128.81mph
Time Trial Run 3: at this time I kept it at high boost, but track temp was 115deg (and going up…), I’ve still go winter jetting in, sled did not like that, so sled did not run good at all, WAAAY to much fuel… also, I popped the intercooler off so no boost/power, may have popped off from the previous run…
1.52 60’ – 5.77 @123.11mph
Time Trial Run 4: Put on the intercooler back on, but track temp was almost 120deg, sled would not even get down the track, still running high boost, air temp was 93deg… Verrry HOT!!!
1.52 60’ – 7.64 @ 72.76mph
At this point it was time to dial.. 95deg-Air Temp, Track Temp is 120deg, they are scraping the track because the track is bubbling up, and now I can see the concrete on the starting line… Not good for racing conditions, let the sled cool down a little more between runs. But, I did get the sled running so it would go down the track. I went 3 rounds (changing from high boost down to low boost), and then lost in the 4th ,( Adjusting the number per round…) made it farther than I thought I would (cars, bikes, sleds) I couldn’t believe it… Am I bracket racer now…
Over all I learned a lot about how the sled reacts per the condition and had fun…
Next time out is this weekend at: Bike\Sled Shootout at NYIRP (
