As far as the spikeyness of the dyno plot, I don't know why it is like that. I wasn't even aware they would be pre/post testing it. Rob at Z Car Garage performed the testing.

And no, I don't have Andy's plot. Maybe Andy can post it. I was there at the dyno day and he dynod right after RickDogg on the same machine. I was very curious to see Andy's results relative to Ricks because they nearly have the same type of mods and they both had a TS reflash to raise the revlimits. So it was a fairly good comparison. The only significant difference between the two setups was that Rick had test pipes and Andy had cats. Both cars were 292 HP and 291 HP respectively.

It wasn't until we installed the P&P lower collector that Rick was bumped up to 296. The P&P didn't add much "usable" power but it put the 4 HP right at the very peak of the curve.

I'd really like to see Andy's dyno plot as well to compare the whole rpm range to see the difference between the 287 motor and the revup's. I'd also like to see where his power peaked since we both have different rev limits with mine being 7100 and his being 7500. By looking at my dyno graph it looks like some timing advance past 6200 could help me a bit to keep the power strong or possibly extract 1-2 more hp.

One thing I really liked about what the dyno graph showed was that the PnP lower collector smoothed out that dip that normally occurs on our VQ's from 4800-5300.

ok so the mrev is swapping out the lower part of the plenum o nthe revup engine and puttign a lower part of the plenum form the 287hp? what is the mrev plus then? how would a mrev be with a plenum spacer?

 

Yes.
The same lower collector modified.
All MREV kits necessarily have the spacer included. Without a spacer, the highend would take a big hit. You wouldn't want it without one. The spacer is essentially mandatory if you want to do anything more than daily driving.

 

ok quick question then how much power and torque is gained with the mrev plus then over a stock lower plenum?

 

The title of this thread indicates what the the most recent independant dyno results were.

 

but isnt the graph for the revup motor? i am asking about the 287hp motor
is there gains when you take the lower plenum on a 287hp motor and swap it with mrev plus?

 

In that case you can essentially extrapolate the spacer gains on a 287 HP out to 7000 RPM to know what it does.

Conversly, you could extrapolate a 287 HP plot (without a spacer) out to 7000 RPM to get the idea.

Jason at Performance Nissan essentially did that same pre/post dyno plot a while back. And although the REVUP engine has variable exhaust cams, "most" of the power curve differences are driven by the different lower collector and higher redline.

 

Here is another set of dyno plots by Spencer over on the G35 driver board. Pre/Post dynos were taken without removing the car from the dyno.

Comments by 13bmx5 (Spencer):
Area under the TQ curve says it all...

 

Haters.......dont be mad cause you only got 287 lol j/k who cares guys 300 287 not much of a diffrence besides the facts are head lights and tail lights look better then yours.

 

Just wondering, how does the Nismo CAI affect the powerband with this MREV+ installed?

 

Agree. I test drove an 06 because I had thought about trading up from my 05. Lets just say... I still have my 05.

 

The power band will have a little squiggle to it but in any case, HP and TQ will be shifted up as shown in the above plots.

 

im just jealous the rev'ed up motors are mod friendly

 

^The ironic thing is we're taking your lower plenum... lol.

But the CVT on the exhaust cam could be the difference maker. :shrug:

 

yea so there

 

wait, whats the difference between the 06 lower plenum and the 05? I have an 06' so why can't I use the stock lower plenum?

 

your stock 06 plenum is different from the 287 hp engines

 

will the mrev or mrev plus work on the 300 hp AT engines?
