S16 Avac Rpm Opening Times?

[Nick_j_r 0]

Hi, im new to the 205 and the S16/MI16 engines,

Just trying to get to grips with information about my engine, im unsure if my AVAC system is working correctly,

the diaphrams both open as soon as i touch the throttle, and then stay open. I have used the search function to try and find information on this inlet system but there seems to be a lot of different answers.

 

Information im after..

- what RPM's should the diaphrams open/close?

- is there a detailed write up about this inlet that i have missed?

 

Thanks, Nick

1800 to 5080 iirc

Thanks mate, so they close after 5080rpm..

are these opened lower in the rev range to give more torque low down?

just change manifold to gti6 alot better

I don't think it is, I still haven't seen anyone back up that claim!

 

granted they have a larger throttle body and less moving parts, but that's it.

I would condsider swapping for a gti-6 inlet! This AVAC seems a pain. I think throttle bodies would be epic! what is involved in swapping for a gti-6?

a lot of faffing

 

the original system works just fine IMO.

Wouldn't that be even more faffing?
