CSI injection track car

[roadsportusa]

I have a CSI injection system that was on a track day car with 2.7 engine. 1976
it is missing the following
1. auxiliary air valve
2. cold start valve
3. auxiliary air devise
do I need these items on a track day car??

Will the CSI system work without these missing items??
Please advise

You could get away with not using 1 and 3. You will need to use the throttle to keep up the revs until it warms up. Without item 2, cold starts will be tough. I would keep the CSV.

My ‘78 track car has the complete CIS components and I moved the car yesterday out of the garage with the morning temperature below 20°F. I don’t think you could make your motor start easily this winter without a CSV. You are half an hour drive away from me and if you decide to install the missing components, I have a free AAV waiting for you.
