I have a 15' aluminum hull w/ delta pad bottom. Running a dominator pump, droop, inducer, ride plate, diverter, set back pump, and sbc. Turns a C impellor 5400, about 5900 on nitrous. GPS top speed w 2 people, fully loaded fuel,beer etc is 70 mph on nitrous.
I have to run a standard rock grate, i run in a real shallow river, 6" - 8' at the deepest normally. Ive tried diffrent ride plate degrees that picked up 1 or 2 mph, but made the boat real loose and not want to turn like i need it to for running the river. I'm running a 2 7/8" nozzle, which seems to give the best performance. Im going through the engine this winter ,
-forged pistons about 10:1
-edelbrock rpm heads, 2.02,1.60, roller rockers
-xm276 roller cam
-weiand tunnelram w holley 450's
-Rewarder OT headers 1 5/8" primaries
-Full MSD igntion, locked out MSD dizzy
Looking for 450-500 before nitrous
The boat seems to ride low in the rear when on plane, but cavitates easily in anything more than 6" chop. I know i need a loader, but thats not really possible. Is it possible to get into the 80's with this configuration? Anything else i can try as far as setup?
