Had the boat out the other day it accelerates so fast. Don't have mph yet but I'm spinning my "A" impeller to 6000rpm were it hits my rev limiter that's with 8psi of boost. Boat cruises nice still, installing boost controller this weekend try to limit boost at lower rpm. Hopefully boat makes through the season started building a new short block for next year so I can turn it more lol. Running very little timing and boost and boat still fast and fairly stable no ride plate or pump mods. Big improvement from last summer pulling 4200rpm
