I'm working on an EMAC computer and can't use the JPC. Can you run the numbers on a stainless steel American Turbine AA impeller at 6,600 rpm for me?
thanks!

Thats because he has that big polished thingy on top of his engine.

JPCIII says 1209 hp. Odd. What changed, Jer?

Thanks guys. those numbers seem pretty accurate.
Can you have them check it with the RPMS you turned when you had no blower belt, and when you were only on 6 cylinders?
HBjet :cool:

My buddy jack is turning one at 7200 in his stealth. Boat literally jumps out of the water. Can't wait to get it on radar.
He is running alcohol blown injected. and according to his egt's he can still go up in temp about 200 degrees.
Make's me feel kinda puny..

Taylorman, latest JPC version (2.1.0) here...
JPC (http://members.cox.net/lvjetboy/JPC.zip)
Seems to work fine for most operating systems. Just download, unzip and run setup.exe. Let me know if you have any questions.

Jer, This is great software. I've read about it on here and always wanted to try it. You have obviously spent a bunch of time and effort writing it. Thank you for posting the download and sharing it with us.

Thanks for the comments Fogger. Imagine what could be done w/serious brainwork and knowledge of those in the business, applied to jet boat performance software. JPC just scratches the surface. I have ideas for future upgrades...but short on time.

Jer, It's accurate too(I'm sure you know this) after calibrating my curve to a berk A, Adding 300 RPM(N2O) the speed showed 71 MPH. On GPS I showed 70.9! Compared to you guys that's slow, I know, but the JPC is dead nuts. A very useful tuning tool.
