When you can’t decide between a fruity sour beer, an ice cream, or a race car… so you just mash them all together 🍦🍺🏁

The Vault City ice cream van caught up with the Sitech Racing 333 car this week and honestly… at this point we’ve no idea what we’re promoting anymore. Horsepower? Beers? Ice cream?
All of the above probably.

The 333 race car is rocking the Vault City Imperial Vault Dweller design
The ice cream van is clad in Vault City branding. We’re fully embracing the madness.

Today I found out how much more power the Sustain racing C50 fuel adds? It took the wheel hp figure from 307 to 319 🙂 that’s with no mapping. So ideal for Knockhill track day tomorrow afternoon.
