The Gulf car at Rennsport was a mock up display and not a functioning conversion. We put it out to gauge interest from the air cooled guys. The feedback was overwhelmingly positive, and we are moving ahead with that development. We will have air cooled product in 2019.
The 991 series system is functional, driving and near-ready. We will be driving to, and at, the Tech Tactics event.
We still have a bit of work to do on the user interface, optimization to get the last bit of power, and other details. I will be able to show you some cool stuff, video, dyno pulls etc in the next couple weeks.
In the mean time here are a couple pics.
