That's a heck of a job Jeff! Congrats! It sure seems like there's a lot left in it! The 60' seems soft and the MPH is low for the ET it's running. I'd expect the MPH to be 3-4 higher. I guess the soft 60' is the clutch being conservative for now so you don't destroy another driveshaft? Just an observation from a lowly automatic racer, lol.

Could I tune it to run faster? Probably. The car is deadly for this type of event. No need to run on the ragged edge. I was actually short shifting the engine at 6400 most of the weekend. Shifting it higher, made no difference. To be honest, I brought a cannon to a knife fight for this event...

For those that haven't followed Jeffs build on this car, here are a few pics: As the Motorvator back in the 70's, then as it was when Jeff started on it about 15 years ago. This is why it is so awesome to see the car resurrected and running so well.

Big Congratulations Jeff! I’d be super proud to have built that car like you did and done so well that weekend. Your perseverence is paying off with the Stickshift. Respect from lots of guys, I know.

Thanks everyone, for the kind words. It's been a long adventure, and big learning curve with this car. The car first appeared at the track in September of 2019, has broken everything since then, and finally won it's first round of competition this last weekend. Winning it's class was pretty amazing.

Nice job!! How does that new trans compare to the old Jerico? Dwayne, the new trans is completely different than the old Jerico. It is soooo smooth, it's hard to tell a gear change happened. It feels like an automatic that doesn't have a shift kit. It just keeps pulling. The front side of Second gears shows the car pulling the most G's, on the RacePak. One of my first runs with the Liberty, just the momentum of the car moving forward, pulled my arm back, and shifted the car into 2nd gear. I had no clue it even happened, until, I tried to pull 2nd gear, and it was already there! After 20+ years of tapping the clutch pedal between gear changes, it's taken some getting used to NOT using it. It's quite nice seeing the RacePak graph not spike in between shifts as well. It was money well spent. BTW, just checked valve lash last night, and it was dead on. Have not had to touch it since being on the dyno.
