Hello everyone,

I was scanning ebay today when I came across this,
http://cgi.ebay.com/ebaymotors/RX-7-...QQcmdZViewItem

If you look at the pic that looks down inside of it, there is a plate which guides the pri./sec. airflow... I have an efini pipe but it does not have this. just wondering if anyone knows if that plate is oem or someones attempt to improve airflow on there own?

thanks

 

That divider was added. This was written up in one of the Japanesse tuning magazines a few years ago and talked abourt on here. It is suposed to help improve mid range power and keep the secondary turbo from overpowering the primary with revese flow when the secondary comes on line. I don't recall anyone on the forum ever doing this mod - if so, it would be interesting to hear their experience. If I were building my car over again, I'd like to try it.
