Let us know how you make out, a link with some video would be awesome.

Re: quad-rotor 565

Whitewater,
Welcome to the board! I have been to your site and seen some video, very interesting. Can you post a link to the engine rules for your class? You will find this board to be a great resource with engine builders and component suppliers that are the best in the business, most of whom are more than willing to help.

Re: quad-rotor 565

Spraying oil on the piston: I've heard of this before where the piston needs cooling. Is this ever used in offshore racing or poker run engines? Is it done to keep ring lands from collapsing; does it have any value in keeping detonation at bay?

Whitewater: In the water conditions you encounter, how do you maintain good flow of water to engine and intercooler?

Re: quad-rotor 565

Tomcat, This is the first engine of mine that will have the piston sprayers,but the fellow that is installing them swears by it on endurance engines.He is the guy with the 1200hp quad rotor.He was saying that he has pulled pistons from a merc 900 and they had lots of color on the underside and when he tore down the quad rotor with the sprayers the pistons looked like they just came out of the box.It sold me because all my pistons are burnt after a marathon.As for the water we just tap of the pressure side of the pump then install one of mercs pressure relief valves and this keeps the block pressure right at 15lbs at wot.I do replace the spring that comes with the unit with a crane cams checker spring and it works perfect.I bought mine at bam marine but the prices this year have almost tripled.Dam merc.

Re: quad-rotor 565

Tomcat,
Here is a link to an article about its use in Cup racing. Ferrari, Porsche, Merc, and BMW have been utilizing this for years in endurance applications. shoot me an email if you need more info.

LAE Kryptonite is now Superior Crankshaft. You can direct your technical inquires to Sebastion Franzen. All of the below vendors can deliver custom billet crankshafts to the requirements of your application. I have worked personally with many of them and can assure you the materials and workmanship is of the highest quality. Collectively they produce the majority of cranks for competitors at the top level of motor sports. Any of them can meet your needs for this project. Carrillo is a very good choice for connecting rods.

I agree with Bob I actually tried to pm last night basically word for word what Bobs respond is with 20 years of modifying repairing and balancing crankshafts I can tell you there is no better heat treating any where then LA Enterprise Crower and Hank The Crank Bryant or Moldex don't use anything else you will not regret it the quality and workmanship is second to none thats why I refuse to build anything thats not with there parts.

Re: quad-rotor 565

Bob, If you go to jetboatracing.com there will be a link on the first page that says 2004 awja rule set.Im amazed how high you guys rev the big cube offshore stuff and yet it still holds together.Its nice to find people that have an understanding of what kind of abuse these motors get and to be able to share good information that could prevent major failures...thanx!

Any thoughts would be appreciated.thanx in advance!

Is it possible for a Whipple to make that kind of HP on a 565

Re: quad-rotor 565

quad rotor 3.3, yes.....

Re: quad-rotor 565

565ci is more than enough for 1500HP. My Quad rotor 2.3 EFI 540 makes 1370HP at 6300rpm. It's actually hard to make less than 1100HP with the 3.3 quad rotor.

I'm using a callies racemaster crank, oliver rods, and AFR 357 heads. I'm very happy with this combination.
