Hey guys as you all know there's a wealth of knowledge on this site. I've tried studying all the answered questions, but the only thing I can come up with is that everything is trial and error. I was hoping that a could get some info on where to start with my pump setup. I have a eliminator scorpion with the daytona bottom with a berk already installed. The suction is about 1 1/2 lower than the sides of the boat, the pump was set back it has no shoe or ride plate. I'm installing a 380 lb V8 with only about 400 hp. I understand these run wet and I'm not really trying to go 100mph. I'm afraid to start buying the wrong parts because of lack of knowledge or because it"s a good deal. Most things are fairly easy to change but I would rather get in the ball park from the start. So basically I'm looking for some info on shoe thickness to start, should i run a ride plate, droop snoot, what loader grate. There is also a possibility of another 100 hp down the road with a huffer but thats probably as hot as i will go. Any info would be greatly appreciated.

First I would post your question to Greg Shoemaker on the Performance Boat web site. I'm not familiar with the scorpion, if it's the one I'm thinking of it had a bad shut down issue. That being said I'll tell you what I did with my Daytona back in 78. Loader, Yes, mine was a center blocker depth I can't remember. Rideplate and shoe, yes, I used about a 1" shoe with a 1" back cut leaving the front edge about stock. I had a flat keel boat too. Now the reason we set it up that way was I ran SKi-Jet II class which was .030 over 454 with single 750 dp. Eliminators back then were fairly heavy. We set the boat up with a lot of lift becauce we were down in HP compared to the drag boat guys. Be warned My boat was excellent in shut down and turned on a dime ( circle boat racer) It porposed like crazy at low speeds due the loader, shoe and ride plate. We also did not have a set back pump and we moved the motor forward about a foot using a Lenco drive line. Be sure to check with Greg he will give you the best place to start with your hull and equipment.

Several things , Photos and more info would be helpfull and re the suction ? are you maybe meaning the intake is this jet intake really set in and setback and not machined for a ride plate and shoe or is it missing them? Tom
