Dang man, glad you're okay!

Ha.

Last Saturday I was tracking while sick and accidentally had a 100+ mph off roading session. Happily recognized it was happening and went off straight, got control, pulled her back on... no damage at all.

Certainly the fastest I've ever driven on grass. Sketchy.

Downgraded myself to intermediate for the next day, so I could take it slow.

Thanks! Still can't believe I didn't hit anyone or anything. Best worst case for sure.

Glad there was no damage!

My excursion would have been similar to yours had that curb not been there. Really messed with the grip in the rear when getting to the bottom of the hill.

Still haven't pulled video off of my car, but this is pretty much exactly what I did: https://www.youtube.com/watch?v=1Fg_vP5IYRA

That looks exciting

Track day done. Some ups, one big down.

Let's start with the good stuff.

HK amp was really dying, so I picked a used one up, did a quick refresh on it (cleaned up and refreshed the thermal paste) and swapped it in:



And wow! I can't believe I had been putting up with the old amp for the last couple years. This thing sounds so much better. I kept having to turn the music down on the drive to the track cause I would hear details that I hadn't heard before and would think they were coming from the car. Pretty happy with this.

Then came a bit of CAD work. Scanned my hacked up filter housing prototype and made the changes necessary for installing:



I have to say that the 3D printer + scanner combo is incredibly powerful. Iterating on this piece would have taken way, way longer had I not had access to these tools.

Test fit piece printing now. Once that is validated, I can move on to printing the entire thing out of PET-CF.

Also, good news is that I didn't see the windshield mount temp go above 70 C, even after letting the car heatsoak in the sun for an hour or so. I'll pull the data later and grab the actual numbers.

But now, the bad news. During one of the afternoon sessions, I came in a bit too hot into Phil Hill and completely missed the turn. Landed with the left tires in the dirt and the right on the pavement, which means I hit the curb at the bottom of the hill pretty hard against the undercarriage. I then drove back onto the pavement for a second and lost it again, spinning out into the dirt on the left side of the track.

Fortunately, the aluminum shear plate took ALL of the damage. I still can't believe I got as lucky as I did. Absolutely nothing else was damaged (including the brake and fuel lines right behind where I hit the car on the curb) and the car stayed right side up.

Having used up all of my luck, I decided to call it and spent the rest of the day cleaning the car up, which wasn't exactly fun. This is what the interior looked like immediately after coming into the paddock:

Vacuumed out what I could, then used compressed air from the tire shop to blow out the rest. Still needs a serious detail (which unfortunately involves removing a ton of the interior trim pieces to get behind them), but all in all, not a terrible result:

Replacement parts ordered. Will spend some hours this week disassembling and cleaning up the car, then can analyze the thermocouple data.

All in all, not the best track day experience I've had, but very glad it wasn't worse. Car drove straight for the entire four hour drive home, all fluids stayed in their places, E86 braces survived and most importantly, no one was hurt.

Hence the old saying "I would rather be lucky than good" 🤣
