Whats the deets on the 525s with turbos?

We are working on some larger turbos with a larger turbine AR to help control the boost creep. As soon as they are on the engines I’ll have updated power numbers (late March). But at the moment they are 875TQ/825HP at 10PSI.

They come with Holley EFI and upgraded fuel and oil systems.

Freshening up a pair of Merc 500efis currently. Blocks and heads are at machine shop now. Engines are out of an 02 Formula 400ss with under 500 hours. Engines were factory sealed and had no issues. Pulled them to upgrade to 525’s and decided to do full refresh instead of just head job. Can private message me or comment on here for my number for anyone interested.
