Anyone running this? http://www.cosworthusa.com/store/pc/...2&idproduct=89

If so, what do you think?

 

i know Rookie and Martyg35 are both running it, maybe a few others..try PMing them

 

Do a search too... there are a few people running em, and from what I remember reading they are not good for NA cars. You might actually lose some power down low, but the FI guys see some gains.

 

For N/A, it is probably not worth it and you are better off going with a Motordyne 5/16" spacer. On the other hand, if you are running high levels of boost, that is when the Cosworth Plenum is supposed to really come alive.

Mine just got installed today. Hopefully we will be on the dyno by the weekend. I'll post my results in my build thread on My350Z when we have them:

been there. done that.

 

^worth it?

 

Where to buy? I heard they're not even in production.

 

Here are a couple of places that have them:

In stock though? I doubt it.

 

^Not sure, you'd have to give them a call.

 

waste of money IMO

 

Cosworth plenums were actually designed for high RPM NA cars, not turbo cars. That's one of the reasons the end caps blow off with high boost... apparently Cosworth never tested them with over 25 pounds of boost.

Cosworth has stopped production and actually relocated their manufacturing to a different company. There will be a version 2 plenum available sometime soon... supposedly around December of this year.
