Jet Pumps / Re: Determining factors for impellors
« on: December 14, 2007, 10:53:33 AM »Dave, it's nice to see you made your way over here too.The Impeller you have is from the newest tooling. Its the same as most of the big guys are running and the same version Frank Nagore ran this past year. Franks is Mag. also, and pulled some very impressive numbers in ET. Like 7.04 What the new Impeller is old to us, in that we tested it 5-6 Years ago just before we lost most all our tooling. We redesigned it into 2 diff. exit port structures and put the blade rap on different angles. We know it works its just can we improve it further and get even a higher water volumn out by another 54 CFM. The one you have is a increase of around 52 CFM over anyone else and has been that way for several years now. We have LOL at the interpretations and copy effects in a attempt to copy this Impeller. What you must do to copy, Is start with the tooling core procedure. if you try to make it the conventional way the core box cannot be pulled, so what they get is a cone and wrap that is quite a bit different yet quicker to produce and less detail time required. We have a couple more tests and then will make a decision on exit port. We know in the pre-tested our cupped works well for the stock application to 500-600 HP its the 1,400 to 2,000 HP now we want to know about. Then will it supply the 11 Vane Bowl the added 54 CFM it wants. Remember our 9 Vane is 52 CFM (non Cavatational) above all others and we just completed up-dating it to withstand higher pressures and force. The same is planned for the 11 Vane. Anyway thats enough about what can be untill we demonstrate it in a monster way at a Drag Race in public its all marketing BS till then.
Is the impeller you sent me last year the same as the one mentioned in your post? I'm just wondering.
BTW, so far it's worked out great. With the new impeller and the inducer installed, the boat gets a real nice bite out of the hole now!
