Friday I got my car to the track for test and tune with a gamblers race. Other than the new engine which I described in a previous post, I changed NOTHING to my setup. Same trans, same converter, gears, etc. Even the old shock settings stayed the same.

First pass, car launched, went a little left (I think I was pointed a tad left from the start), car laid down a 1.1883 60', 3.4847 at the 330 and a 5.4586 at 123.93 mph in the 1/8. I stayed in it longer than expected for a first pass and got a 1,000' time of 7.1818 at 140.58 MPH. Lifted in between the 1,000 and 1320 and turned on an 8.67 at 144 MPH. Man that was a shock to see that.

Entered the gamblers race. First round dialed a 5.44. Before the first round, we turned the vacuum pump up a little bit to see what it would do. I was .011 on the tree, another 1.1860 60', 3.4615 at the 330, hit the brakes in between the MPH and ET cones. Took .008 stripe to be under by .0134. Ran a 5.4266 at 123.66MPH. My opponent was .001 dead 5. So a package of 6 total. Warm welcome back to the top bulb class lol. I was happy with the way it ran, and happy I could still hit the tree. Didnt really care about the loss. The 5.42 was a personal best by .01 from the previous setup which ran the best of 5.43 in better conditions at a better track. So it looked like the new setup was promising.

I was able to still test and tune after the loss in the gamblers race. I increased the 2-3 shift RPM 100 rpm because the car seems to like more RPM. Third pass, air got a little better, sun went down. Laid down a 1.171 60', 3. 4361 at the 330, and a 5.390 at 125.28 MPH. Personal best. What a fun night. Two of my close friends and teammates raced each other in the semi finals. Friend who footbrakes (one of the baddest footbrakers in the country, Nick Bownan), won against my friend with the delay box, lol. Then Nick went onto the final against a 4.80 dragster. Nick laid down an 11 package to take the win.

All in all, awesome evening. My car really seemed to like the new engine. The bottom end with the little extra stroke seemed to make the car work better (Surprisingly).

The video I will upload is the first round of eliminations and I do not have an outside video of the 5.39 pass. I will upload the gopro videos when I get around to it.

Now that I am back in the seat of my car, I am excited to see what the rest of the season brings.

Really, really nice effort all around. Great job.
Got a friend who campaigns a 235 radial car, it’s been 5 teens on spray. It’s a bad boy. It 60 foots incredibly hard, think he is right about where you are, maybe a hundredth or two quicker. Disappears quickly standing behind it
So the fact you are 60 footing that hard and high 30’s says to me your car might well get in the 20’s once you get it all sorted. And your NA.
Wicked fast!
