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....
