guess a difference in preference?
you want great topend, you buy an S2k
you want grunt and useability, you get a Z
a broad powerband is inherently more useful and makes for a quicker car than a narrow powerband, high revving engine. the revup had a deficiency that people noticed, making the engine slower, though rated high because of the increased disparity between peak outputs though the DE was 'fatter' under the curve.
the idea of the mrev2 was to provide some mid range grunt that was lacking while keeping the technological advancement of the higher redline and shifted powerband to make the engine stronger all around.
at least that is my take; you get the best parts of the DE with the best parts of the RevUp

your opinion. I like my DE
also, this is based on drag times and dyno sheets. (and ~cough~ streetraceswithrevupowners~cough~)
it was not shown to me in my time on these boards that the revup was a superior engine in terms of overall power output. superior at losing oil, sure, but that is about it.

And I didn't use the word "significant" until now.

The data shown is exactly what came out of the dyno machine. This same data was offered to all the contestants by Sport Z Magazine (now Nissan Sport Magazine).
Besides, there are two very big and very obvious reasons why you should automatically know the plots are 100% true.
1) If anything was falsified, you can bet the other companies would raise holy hell about it and would (rightfully) be screaming all over the forums about it.
2) All the results have been published in Sport Z Magazine. Any one can easily cross check the results as shown in the magazine. And I'm sure that has already been done by many, many different people.
There were also about a dozen independant witnesses at the dyno shootout. They also frequent this forum.
The data shown is what actually happened on the dyno and is verifiable through multiple independant sources.
------------
As for MREV2 with the 5/16" spacer on a REVUP engine, the average power per gear is higher no matter what gear you are in or what RPM you shift at.
To date, MREV2 is the most effective bolt-on short of nitrous or FI.
The only other mod that may have a chance of outperforming the MREV2/spacer combo is the Cosworth plenum. And we will only know if/when its actually released for independant dynos.
Hydrazine:
did you ever test out any lower plenum replacements? or modify/polish/port them at all?
I always hear the engine guys talking about that being a problem area and wondered if you had tried anything.
