I've posted tis in another too but more ideas the better. I was a little disappointed today. Carried the boat to the river and made a few passes. Let’s take in to consideration it’s a 13.7/1 555with Canfield heads(350cc) two 750,s cam is 270ish @ 50 and .700 with 110LS.The pump has an open loader, inducer, A Aggressor impeller Place Diverter ½ droopand 3.125 bushing. It turned 5800 RPMs and ran 95 MPH deep down I thought itwould turn 6000 and run close to a 100. Anybody know how much of a bigger bitean Aggressor gets that American Turbine?

Aggressor impellers bite a full size harder than the A/T, like a hi helix. You need more R's in my opinion.. If you cut that AA down to a AA - you should see 6K . Ask Tom , see if he agrees...Jim

Any idea how the bottom is on that boat? I'm only asking because I think it should run well over 100 as well. A nearly 14:1 555 with a big cam and canfields should be more than capable of triple digits in a 19 IMO. A buddies 19 CP runs 102-104 with a pump gas 509 and Merlin heads. A few more revs would probably help it some... Does it have any blocker in it?

Fine tune the setup of the boat, get the pump working good, get the RPM sorted out. It should run. Those boats work really really good

Grady 95 ain't nothin to be disappointed in in a boat that just came off the trailer with no tuneing done .. Work with your setup alittle and might have to trim the impeller a hair and ur right there . Good luck with it buddy :thumb:
