I understand old school engines like we have in our jet boats. What I'm trying to learn is all about high performance jets. My current engine set up is as follows:
Chevy 468 4-bolt, forged crank, GM heavy duty 7/16 rods
JE Flat Top Pistons & Rings (close to 8-1) Spec'd to Bob Teague's recommendations
Iron square port heads with ports cleaned up (To be replaced with AFR CNC ported heads when money allows) Teague Roller Rockers that fit under stock size valve covers
Edelbrock Victor Jr Intake port matched by me (What fun that was) Aluminum is a pain.
Comp cams 11-568-4 Lift .575 .595 113 degrees lobe seperation. Springs to match (Stayed Hydraulic Flat Tappet) Comp cams Pro Magnum Lifters. Manley push rods
M-3 Pro Charger with intercoller running 9 psi. QFT blow through 750cfm carb. Fuel system set up for this application. MSD ignition.
Engine runs strong to 5800 rpm with the pump that came with the boat. The tag on the pump is worn so I'm not sure which pump I have. It's a polished style with an extension after the bowl that is a foot long with a wedge in place. The bowl goes right up to the transom. I do have hand control to raise and lower jet. I've been taught to position the jet with the water just above water level at full power.
I have heard good things about Cyclone Marine in the SF valley and will go talk to them at some point, but I want to know everything in detail before I do. I'm in Valencia. I'm open to advice on pumps and the set up to acheive maximum push.
Thanks
