Couldn’t be more exited!!! Project 21 Daytona is starting today. . The whole point of this project is to use as a tool to develop, test and prove @griffin__performance complete turnkey engine packages that we will be offering to the public. The focus of these power plants will be centered around reliability, endurance and packaging to fit in a wide range of marine applications. They will be ranging from 800-2,000+ horsepower utilizing the latest EFI, turbocharging and parts technology currently available. These engine packages are currently in development and will be releasing later this year. Keep your eyes peeled for the updates! 👊🏼 @griffin__performance

If you’re either a single guy/gal that wants a fun hot rod that’s small enough to run/dock/launch solo or a family of 5 that wants to be able to play in the big waters or the tight curves of the river definitely check out the new @gmspowersports SR 23 cat. . This lil hot rod rides like the big cats being able to handle 3+ft chop with ease, has a ton of floor space, seating and storage like the big boats do but doesn’t have the hassle and price tag of the larger boats. Build quality rivals the highest quality million dollar rigs and the coolest part is, you can option it with outboard, sterndrive or jet propulsion. . Im already having withdrawals of driving this boat and can’t wait to do it again!! #GriffinPerformance

Got some seat time testing the 2025 @mtiboats 390X powered by some @mercuryracing 500r’s. This boat was BEGGING for the rough water as we were cruising over 4ft chop at a very comfortable 110mph and when we let it stretch its legs we squeezed 127mph out of it as it was still pulling. Craftsmanship is beautiful. Fit and finish is seamless and the beautiful rigging eased my OCD 😆. Great job MTI, looking forward to exploring more of your boats. #GriffinPerformance

Customer brought in this cam only LS1 he pieced together for his jet boat so he could make sure everything was good to go and tuned properly before he drops it in the boat and heads to the water. . This session proved to be money well spent as we found a couple little mechanical hiccups he needs to tweak but all in all we finished the session with a healthy 489 horsepower and a broad torque curve making north of 400ft/lbs from 3500-6500rpm. . #GriffinPerformance

Unboxing some goodies for @scott_bahde new big block build. This one’s going to be a high compression naturally aspirated screamer going in his beautiful CP jet boat. Can’t wait to see how this one performs 🏁💪🏼. #GriffinPerformance

I’d say our boost building strategies are both effective, consistent and cool as hell to watch. 🔥🔥🔥🔥🏁 #GriffinPerformance

Had a very successful weekend with Bryan Glidewell and his crew running his Cheyenne jet with his new #GriffinPerformance 427 LSX. The boat got faster and faster every pass and is now a couple tenths away from its personal best. Unfortunately the pump shaft decided to call it quits going into round 2 which ended our weekend early. . We are looking forward to working with Bryan and his team over the course of the season to assist in getting the most out of their program! 💪🏼🏁 #GriffinPerformance
