We started off 2019 with the first RaceBBi track day at Willow Springs Raceway near Rosamond, CA. The main track, Big Willow, is 2.5 miles long with nine turns and significant elevation change. Willow Springs is also the oldest permanent racetrack in the United States, opening in November of 1953. It is now a Historical Point of Interest in California. Fastest time at this track is 1 minute and 6.05 seconds as set by Michael Andretti in a CART Indycar. Please don’t try to beat that… yet.
Some cars were delivered in time for the event. We had just completed another milestone for the BBi 4.0l 997 GT3: full E85 compatibility. That means a new in-tank fuel system update, injectors and flex fuel sensor. The Syvecs ECU handles all the tuning changes with the flex fuel sensor. Our calibrator was collecting data logs as the car ran the sessions. Nothing beats real-world data. This is a real example of how much can be done when we have full control over the engine, being able to adjust the smallest details to enhance performance and drivability.
The 991.2 GT3RS has barely over 100 miles on the clock and was finished for this event as well. BBi StreetCup spring package updates the spring rates and our Corner Balance and Alignment set it up for the track. Wheels were swapped to the Manthey BBS WEC spec Magnesium wheels, wrapped in the new Michelin Pilot Sport Cup 2 R Tires resulting in massive grip and weight loss. BBi 3D printed inconel long tube headers with side muffler deletes uncorked the already impressive engine (and reduced weight) To top it all off we loaded a BBi ECU calibration to take advantage of the flow and get a bit more power out of higher octane fuel. The car is quite impressive out of the box, but there is more to be had and we will keep dialing it in.
The Ultima GTR always turns heads (and ears) and it was back out for some more testing and validation. Its an impressive machine as its built like a race car with a massive engine and now a sequential transmission. MoTeC keeps the powerplant going and the traction control logic works great to keep the car steady. We collected data logs to ensure all is within spec.
