Try posting the vids on YouTube.
I contacted Julian this morning and found it may not be possible to export the dyno data to Excel for additional analysis. The dyno software doesn't normally export the data in text format. I will contact Dyno Dynamics to see if it can be done.
But even without the additional analysis in Excel, with just a visual inspection, the dyno plots make it clear... there is no other NA REVUP bolton more effective than this.

5/16" Vs 1/2"
RBlover,
I remember you were asking about the differences between the 5/16" and 1/2" spacer on the MREV2.
Although there has not been a direct comparison of the two spacers on a MREV2, these plots here can give you a good idea of what is happening between the dynamics of spacer size, internal volume and their relation to HP and area under the curve.
There is not much difference between the 1/2" and 5/16" but there is some difference that can be consistantly measured.
Compared to the 5/16" spacer, the 1/2" makes a little more HP above 6K and a little less area under the curve below 6K.
If you look closely at the midrange of these newly generated MREV2 curves, you will see a slight loss of midrange when the 5/16" spacer was added.
I've seen this same trend on every REVUP test I've ever done.
When you put on a 1/2" spacer, the midrange loss is even greater but there isn't quite enough increase in the top end to compensate for the loss everywhere else.
Basically, a minimized plenum internal volume is good for TQ and area under the curve. A maximized plenum internal volume is good for very high end HP.
I did all this same extensive testing, with every configuration, on the MREV and MREV+.
Overall, the 5/16" spacer is slightly better optimized.
Just a FYI.

I know on REVUPs, the COMBO is recommended... But would a REVUP with ONLY the spacer (not Mrev2) dyno something similar to the green? How would JUST spacer compare to JUST MREV2?

Hi Tony,
Was reading up on the previous posts and about authentic MREV2 and what not. I got my MREV2 and spacer end of 2006... received them early Jan 07. Just want to make sure i got the genuine parts. I only managed to take some pic of the MREV2 then and might not be clear. Wondering if you can tell if mine's genuine. Thanks heaps...!!

The spacer by itself doesn't do much on a REVUP lower plenum. The MREV2 works all by itself on a REVUP but it works even better with a spacer.
If you can only do one or the other, start with the MREV2. You can always add the spacer later for more top end.

So is it to say on the non revup motor ie a 2004 350z when you add the MREV2 and spacer the gains will be around 30-40hp correct? If so what spacer I am confused on that when reading all this...

For your application, I recommend just the 5/16" spacer. It has the best bang for the buck.
Its fairly easy to install too.

Yes, it does. Performance is very much like a spacer on the non-revup engine but with a little more TQ.
Wired24/7 (Mike the moderator) did a series of dyno tests on it and posted the results a while back.
Note: The average gains with the MREV2 is very slightly higher than that of the spacer. But because it costs more, this is the reason why I generally recommend the spacer for "Bang for the buck".
