Title: Comp jet racing
Post by: Rogers57x on January 20, 2020, 10:17:15 AM: Fellow comp jet racers , going to compete at Burley and Parker this year , need some info please I've run my boat pretty hard for the last 10 yrs , on my 5th motor 2nd pump , but need to set the boat up right , I do not have a turning fin , where do you put it so it
Doesn't interfere with the water flow to the pump intake, boat slides a lot then hops if cranking to hard , i do have cav plates to install but dont want to rob them off my Rogers Dragstar, The boat i have is a Sanger superjet so using my divereter with a stop is all i got for now going to make more changes with steering and setback seat ,center imco fuel tank and other mods unless someone has a rogers set up for sale less motor? not a lot of circle racing up here in Washington just want to be competitive anyone with any info would be awsome!! Thanks

U don’t need cave plates on a jet boat as the Diverter will set the boat up , ride plate is a must . Ur gona want to get ur pump set up with the tightest clearance possible and run an inducer as well as this will help keep the pump loaded at all times . Send some pics of the rear of the boat so I can see the chimes on it .

I would try putting a rudder on the pump and see if that helps with the turning ??? Easy and cheap lol . The turning fin will help keep the boat stable on the turn as this is what it’s for , when the nose of the boat drops the fin will keep it from wondering all circle boats have these . Do u have an inducer ??? As I said before this will help keep the pump loaded at all rev ranges ??? As for the oil cooler it’s a must , extra oil . And u can control the temps better . Also do u have a pressure valve to keep ur water pressure steady???

Post by: Rogers57x on January 23, 2020, 02:29:29 PM: Thanks for the information really appreciate it, I did forget to mention that yes the pump does have a inducer , I was told that I could put a water pressure gauge on the pump to see what psi , and what type of oil cooler would you recommend I see a lot of Dan Olsen coolers used , I do not have a pressure valve for my water , there is a ball valve on the inlet and out so I can control temp that way , I do have a old Berkley rudder that attaches to the pump but it's huge looks like a rudder to a battleship I'll trim it to fit it looks like it will hit my ride plate now , do you know how big the race course is at Burley or Parker? 1/2 mile ? Speeds for comp jet? Just curious 😎thanks

Both were were set up for circle boat racing. Both were National Champions. They ended up putting fins under the boat, line flat bottoms still do. Made them track straight, and not slide in the turns. George Striegel is owner of Clay Smith Cam. Her would be a great person to talk too. 714-523-0530
