Re: turbo theories Part ???

On my '81 Rabbit, I had the air horn out of a T600A to molest bad 
drivers. (Nobody expects that much sound out of a rabbit)  It required 
about 120 psi to operate. I Got an old FREON tank, and put on a schraeder 
valve so I could refill it at the gas station. I started thinking about 
using an emissions air pump to refill it, but nowhere near the right PSI. 
It didnt last for more than 3 blasts without a refill. I would guess the 
turbo would require similar volume to retain that rpm, which means on a 
30 pound tank, you'll get about 3 shifts out of it!!! We'll have to 
figure a way to have the engine refill it....
