FYI I was told that scat makes all crowers billet cranks.

Re: quad-rotor 565
 

i thought most scat cranks were forged in china... and machined here...

Yes Shaun after dyno tuning and a couple hours testing then 5 hours racing she ready for a tear down.

If you don't know the answers to these questions you shouldn't be building this motor. Not just anyone is going to give you the correct answers.
I say run the scat 9000 4.25 crank and the scat 5140 rods no need for overkill with only 1500 HP.

No. Crower has his on foundry.There not cheap

1500 h.p. and a 700 lb aluminum hull :eek: :eek: My main concern would be my own survival not the motors. Good luck with this one.

Whitewater,
In the application you describe I doubt there is a crankshaft you could use that would be described as overkill. It will require the necessary budget to be successful. 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.

Gentlemen,
Before everyone gets there panties in a knot over his questions, look at his username. "Whitewater". This guy is a jetboater who races up and down rivers at over 100 mph. This is the style racing you see in the Northwest.
Be a little open minded and be amazed at what these guys do when it comes to racing.
We are here to help, aren't we?
Whitewater, welcome to the board. Can be a little rough at first but if anyone knows rough, it's you. I have always been facinated with your style of boat racing. Are there any websites that gives information on Jetboat River Racing?

Re: quad-rotor 565
 

Thanks for the welcome Rlw! Here is a couple excellent web sites on white water jet boat racing.www.eagleracing.ca and www.jetboatracing.com .I will be posting my latest race engine for sale on this site,It took so long to finish that when it was done 700hp was not enough power to be competetive in A class.I dont know if a aluminum sbf would work in your bigger boats because lack of torque.But its built to run @ 7000rpm all day long.The price may sound outragous but Im selling it .50c on the dollar.Every peice is brand new less dyno time.
