Water Injection

[Simon Quested]

Hi All

I have designed a simple circuit using a 555 a a square wave 
generator driving a power transistor switching an injector I'm using 
a pot to set the duty cycle. 
The injector only comes on under boost.

What base frequency should I use? I am starting with 1K Hz

Who has used water injection ? Any do's don'ts or suggestions?

My plan is with water injection I can crank the boost level up with 
out detonation problems.   

Cheers

Simon
