Yeah.
32:13
And, um, you know, same with, like, the sled pull.
32:17
Um, I'm kind of actually more on the liberal side for sled pulling.
32:20
I want all the horsepower and I want it to be hauling ass down the track.
32:24
And, you know, Chase will sit down to me and go, "Ken, you need to treat this like a 3.0 puller.
32:28
We're gonna pull back the horsepower because your chassis is not set up to handle it, and it's just gonna light the tires off and do not, do nothing well." You know, me not having as much sled pulling experience, I'm like, "Maximum horsepower, maximum tire, and, and let it rip." And then, you know, coming from, like, Chase's perspective, he's like, "I'm gonna set this up like a 3.0 truck that we have a ton of experience with, and we're gonna get a solid pass down the track." And that's kind of like the, you know, the back and forth that we go through each day, just leaning on everyone's experiences.

Ryan, another one on the track, you know, drag racing is Ryan's domain, so talking to him about ramping in nitrous, you know, and, like, when lockup command is going on, you know? And he's so good at seeing that, "Oh, you know, we, we smacked the tires," or, "Oh, you know, we ramped in too hard.

It always sucks to ship engines to California.

Maybe in the off season or downtime is just sending off a sample, seeing if there's any sort of abnormalities, you know, in the, in the wear or anything like that, just to stay on top of it.
15:50
Yeah.
15:50
And we've, we've actually done that.
15:51
You know, we've got the, um, the oil test results back, and I was kind of blown away 'cause I've never, I've never done that before.
15:58
Um, but, uh, you know, the last couple times we have, and, and you could even tell if your, you know, your shop rags are dirty, right? There's particulate counts, there's like fiber counts, there's, um, you know, if you run coolant, we've seen that.
16:11
We don't run coolant anymore, so we got rid of that problem.
16:13
But, [laughs] um, you know, and just getting that kinda like breakdown of, you know, what, you know, the sick content or like, you know, how much, you know, fuel is in your oil.
19:17
Are there rivalries? Like, what is that side of it like?
