Day 1 is in the books. Spent the morning tweaking the car and learning the track (and car - only second shakedown of the car). New alignment made a HUGE difference in the handling.

Here's a quick and dirty lap that I was logging for some ECU data - still fine-tuning the engine tune and currently trying to determine the source of some fuel pressure issues (dipping down to the mid forties PSI under WOT from the regulator set at 54). Hopefully we can get it figured out and start doing some harder laps after.


Car is an absolute rocket - 159 mph down the front straight and 157 into T5 and I'm still taking it easy.

That's a huge temp differential between water and CHT! Any idea why that is? I thought it was generally accepted that CHT was roughly 15° higher than water temp.....maybe that's only applicable to more OEM setups. 🤷‍♂️
That’s interesting, first I heard about 15* water temp offset to CHT. My understanding is CHT is the only real time sensor data displayed to the driver (including a numeric scale!). Using only the factory virtual gauges (‘14 GT), CHT max is usually 230* and moves down from there as “OilTemp” gauge moves into yellow then into red. Once oil temp is in red, back off a little and in short order I’m back into green.

Great meeting you @ Road America Kevin. An incredible build and for those that haven't met Kevin, a great dude. Please let us know if you'll be back next summer .... we all need to get pit space together.
