To put it another way "If Ferrari can't spend $400m on F1 anymore, it might as well spend money on another racing series it can use as a pretext for research that will improve it's F1 car".
Based on Ferraris performance in F1 over the last decade, you could give them unlimited amounts of money in any series, and they will find a way to...not win.

> These components need airflow to keep from frying while the car is parked, so a Home Depot’s worth of Milwaukee M18 Fuel leaf blowers ($387 each, including a lithium-ion battery) is stuffed into the beast’s many openings.<p>This was as entertaining to read as it was to see visually. That's such a funny solution for a multi-million dollar endeavor like this.
The article has a photograph of the car, with electric leaf blowers shoved in all the air intake holes. It's worth clicking the link just for that.<p>PS - I have some electric tools that use those same batteries, and the spares are so expensive it makes me angry that I chose that battery system :(
