Cold Start - Hot Air Induction Tube

After having extractors fitted some time ago and the original heat shield removed, the tube from the air intake (3.9 CPI) that used to run to the exhaust is now just shoved between two extractor pipes. Its looks messy. Can I just remove that tube? I know it is meant to help with startup and then switch the intake to the front intake but as it isn't attached like original I thought it may send wrong temps anyhow. Can I rip it out?

Cheers

Yes you can remove it. Then wire the butterfly in the intake snorkel so it is fixed in the cold air position.

Thanks for the reply. Excuse my ignorance but how can I wire the butterfly closed? It is encased in the tennis racket. I can push it closed by hand but it is not obvious to me how to keep it closed perm.

Re: Cold Start - Hot Air Induction Tube

I actually can't remember exactly what they look like as it's been 10 or so years since I owned a CFI Falcon.

It may not even be able to be wired up, however what I meant is to somehow(?) fix it into the cold air position.

The butterfly valve is operated with vacuum - from memory, I reversed the one way valve in the line and it forced the valve to stay in the cold air position.
As I said, it's been a while so I may have this a bit out of whack.

Rick.
