I have parts at an engineering facility being flow benched and critiqued. There are no further dyno comparisons or tests planned. I will however be able to tell you the amount of increased flow over a stock upper plenum. I am hopeful that the increased flow will sway some people to take a chance and do testing themselves. 3rd party testing is usually the most brutally honest testing.

This is probably one of the most accurate and intelligent comment/replies I've seen on this forum.

This type of testing would yield the best comparison from the OEM specified plenum/manifold. It won't show many of the discrepancies in the results that cause a poor evaluation of the given test part. The independent variables such as the difference in tune, or the application's upgrades will be left out of the equation.

So I was the one who picked up one of Matt’s plenum. I picked up a maxima throttle body and harness at the same time from him.

I just wanted to thank Matt. He is extremely knowledgeable about the platform. He took meticulous care while installing the plenum on my Z. He treated the Z better than I ever had and better than some other shops. There were no issues with drivability and everything looks awesome. I wanted to do a before and after dyno, but it would cost as much as the plenum itself.

That's great to know.
If it's possible to send to the UK, I'll PM you later in the year
(as I'm likely to do cams\chain\long tubes at the end of the year)

I'm sure it's possible to get it to U.K. Cost of shipping might be a little nuts.

1cockyZ you disabled your PM's/messages, but consider it sold. If you could PM your paypal and price shipped to 32817, would be great.

Edit: I got my plenum the other day. It looks great and I can't wait to install it and get a retune. Thanks Matt!

Was able to install the plenum and its running great and everything fit with no issues. Its running pretty lean at 14.5 at wot now. I was tuned prior to this manifold with my mods being 3.5'' intake, nwp tb, v+, 5,16'' spacer, mrev2, dc headers, berk tp, stillen catback. I'll be getting a retune at the same place I was originally tuned out soon and post the dyno. Thanks again Matt!

Did you keep the 5/16 spacer? What was the previous a/f ratio? When do you plan on dynoing? I have basically the same setup without the NWP throttle body but with Tomei 264s so very interested in this.

The prev afr was always high 12's-low 13's at wot with those mods listed. I have the 1/2'' spacer now instead also. Hoping I can be fit in tomo or wed for a retune on the dyno.

Sounds great. I am real interested to see how it turns out. Also, i am curious to see how much injector you've got left. I am sitting at 90% right now so anything else I do powerwise will need new injectors and tune
