MREV+ installed on a NON REVUP engine!
Hi Guys,
I've recieved a million requests asking if the MREV can be installed on the 280 HP engine. Unfortunatly I had to turn them all down because the MREV is simply a spacer with a lower plenum from the 280 HP engine. ...So if you have the 280 HP engine, all you need to do is install a spacer and you automatially have a MREV.
But you know of that machining process I have been doing to the MREV+ lower collectors to allow for more air flow?...
Well, I dynod it on a 280 HP engine and it made surprisingly good gains.
Analysis is done! Here are the results:

So yes, MREV+ can be installed on a 287 engine.
If you already have a spacer, all you need to do is modify the lower collector and it will make more torque and more horse power! In addition to area under the curve, it will kick up the peak HP by about 4-6 HP.
This is a completely new catagory of plenum modification for the 287 engine! :beer:
Lower Plenum Core exchange for the 280 HP engine is a go! I'll set up the Motordyne website to accomodate core exchanges.

say again? I'm kinda loss.
I have an 03-280hp engine.
The MREV+ will work with my engine? I can get that MREV+ and expect better gain the the 5/16" spacer alone - According to the graph, the gain is almost doubled the 5/16" Spacer?
So I need both???

I've seen so many stock dynos of each and they make the same numbers. (+/- 5 HP)
If there ever was a difference it must have been in the very, very beginning of G35 Sedan production.

To mix things up even further. Okay this new mod tested on the 280 hp engine is a modded lower manifold + spacer.
Now you say it would work equally as well on the 260hp versions. Sweet!
Now. I happen to have a Crawford V5. Would the modded lower manifold + Crawford plenum (or any plenum for that matter) still net some decent results?
Logic being. The modded lower is the key to the hp gain. But a spacer or maybe plenum is needed to allow the engine to breath well enough to realize that gain? It might not matter where the improved breathing comes from?
I assume this modded lower can be done to any non-revup piece?
Thanks
