Some turbo vacuum questions.

[73GreenMachine]

I am planning to run an rx7 turbo drawthrough LPG on my Ford TC Cortina. Is it fine to hook up the brake vacuum and the dizzy vacuum to between the butterfly and the turbo inlet(cool side)? If I've missed it in another post just tell me and I'll look there . Thanks.

brake boost vacuum on a draw thru goes before compressor inlet
