water injection

[AcroChik]

Fascinating.

Thank you everyone for this thread on a topic with which I have no direct experience because of the types of a/c I fly. Absolutely fascinating reading that's given me a perspective on the subject. Some of the posts in this thread are models of concise explication of interesting engineering. And overall a great exchange of ideas.

Great job!

One day I would love to run water injection on my RX-7. Aquamist makes a great kit for 400 bucks.

This stuff works well for cars too. esp the turbo ones.

I have a built 9 second '94 Turbo Supra with a 90 shot NOS kit, it also has water/alcohol injection. When I run more than 12psi I don't have to worry about detonation running 93 pump gas. It works great especially when you want to run 22 psi and don't have time to get race gas. It pumps in windsheild washer fluid, the Grand National guys started doing it back in the day, now they have inexpensive kits for built motors. I wouldn't bother getting one unless you upgrade everything that can break, because it will.

The J57 was not as good as the CFM56, not even close. But A model guys had much better takeoff stories: rotate at rotate speed or 1000 feet remaining, whichever comes first.



All the smoke on a wet thrust takeoff was something. If you were in position on a MITO you really couldn't see the guy in front of you due to the smoke.



There were two water pumps, one for the inboard and one for the outboard engines. I was told that it was originally left side/right side but a pump failure caused a mishap.

Water On!

What is max power in a CV-580? Two Reds and Two Greens (two over temp lights and two water on lights). Those that flew her will understand... Wet takeoffs in that airplane were a blast!
