The team at are cooking something up! This build features an IAG billet block, dual-injector TGV housings, and an RCM dry sump, just to name a few of the highlights. They are aiming to be the fastest Subaru in Chile 🇨🇱

Someone once said “You cant find the limit until you step over it”. Unfortunately, Dewey found the limit when trying a bit too hard into Turn 5 this weekend. Thankfully the damage was minimal to the car. We’re still not sure about Dewey’s pride though 😛 (Seriously he’s fine)

After realizing that a baffled OEM BRZ oil pan would not solve the oil pressure drops we experienced on the track, we decided to engineer our own solution. After continuous revisions and over two years of rigorous track testing, we are excited to introduce our patent-pending oil pan. This final design features a larger capacity and improved inner baffling to effectively address oil pressure drops during high-G-force corners and braking zones. IAG's new FA20/FA24 oil pan is compatible with many popular aftermarket headers, ensuring there are no compromises. We are currently in the manufacturing phase of our final design. Stay tuned for the release coming later this year!

This weekend is at Gridlife Circuit Legends at Lime Rock Park, one of the last events of the season. We were not able to get parts to fix the sequential transmission in time, so Dewey will be driving Boogeyman with an H-pattern transmission once again. The team is hoping to keep the winning streak going this season and beat the overall Street Mod record of a 53.887 currently held by Allen Patten. Tune in to the Gridlife livestream this weekend to watch the action! 🏁
