Race Tracking Your Supra - Information exchange

[FLtrackdays]

Stuff slips, bends, breaks also. Often even temps aren't possible because you're always turning one direction, although that's always ideal of course.

What is possible, however, is logging consistent trends with your tread temps at different tracks under different conditions and also preventing excessive temps from destroying your tires. The pyro will tell you if you need to make a spot adjustment or if something has changed that you weren't necessarily aware of. A tuning tool.

Indeed. I’ve been on this same track for quite a while. First time I’ve corded the inside. Again, hindsight is 20/20. More likely the tires were used a bit longer than I’m remembering. Perhaps I drove in town longer than I normally do. Too many factors in this case that I’ve muddled up. I really need to log how many track miles I put on them vs driving around town. Unfortunately I’ll have to wait until next October. I’ll be slapping on the OEM shoes sometime this week ?

WTF is a Pyrometer ??????

 

[Vegas17]

This is a good read on why a probe pyrometer is better than a temp gun and what readings can mean.

WTF is a Pyrometer ??????

A butthole thermometer for your tires, except the whole tread is the butthole. Stick it in.

Quick follow up on the Catalyst: I enjoyed it -- it works well for someone who knows what they are doing and are searching for time.

Pros:
- really easy to set up and use, one time to calibrate the video, and then it was plug and play
- not too intrusive; by default it only tells you if you got a corner right. You can set it to tell you where it thinks you can improve a little.
- UI is easy to understand and read.
- easy to bluetooth a wireless earbud into it
- there's a base 32GB Micro SD card, and you can add an additional one up to 128 GB. Allows for up to 70 hours of video.
- you can review data on the device
- the magnet holding the Garmin is really strong. It didn't come off with 1.5Gs of cornering or braking.

Cons:
- Garmin doesn't support exporting data to a computer, only video (with some really basic overlays). All data reviewing has to be done on the device
- took like 2-3 minutes to get a good GPS lock when starting up the car for a session
- the mount that comes in the box is suction, which will eventually get loose
- pricey

It's a good intermediate to early advanced tool once you know the track's basics, but are looking to improve. If I were going to a track I haven't driven before, I'd probably take an instructor to learn, and then use this after a couple of sessions.

It's also not connected to your car via OBD2, so if you need additional telemetry like IATs, ignition timing, etc, you should probably look at a different data logger.

Managed to consistently hit 1:44.6s last month at CMP as I got more comfortable with proper track tires and brakes. Went back yesterday with goal of low 1:44s or God forbid breaking into the 1:43s as track conditions were similar. Was able to achieve my goal with a 1:43.76. Shoutout to @Traxion and @AHP for their advice and help along the way.

Thanks for the insights. I’m driving with instructor for as long as possible so this device is not useful for me at the moment.

Also it maybe due for a refresh soon?

in the meantime RaceCapture works nice for me for the post track day analysis and the nice video overlay capability, and is a little cheaper + gets car performance data from CAN

the only downside is installing that requires some minimal wire tapping. But not really that hard.

man that's awesome-nice win!

What tire pressures should we be aiming for on Nankang CR-S v1? Currently running 34 front, 32 rear cold

ambient temp is in the low 80s today

Not a recommendation for that tire specifically but in general 30-32 hot on 200tw. Start at 27 with those ambients, you'll prob end up 30-32 on the middle laps and slightly above on the final laps. If you have TPMS check as you come off track. If it's clockwise then driver side will end up higher than passenger and vice versa.

Those should be your hot targets. I usually go out with 26-27 cold.

How does the car feel with Pure800 vs 700 now? Any differences in the power band? Did you retune it?

 

[Mori]

Thanks guys, lowered hot psi to 34 front, 32 rear and felt way better last session, the amount of grip honestly caught me off guard considering these CRS are on their 8th HPDE day

Yeah, as I get more seat time, I'm eventually going to need the additional data from CAN; almost everyone who is tracking that much jumps to the AIM solo or some other solution.

But for now, the selling point of the Catalyst is that it just works, and you can review trackside.

No idea, been sitting on quick jacks since last Saturday. I got really sick with Bronchitis shortly after installing the turbo.
