Hi guys,

I need your help and your opinion to do my next mod.
I am looking for a plenum mod but I hesitate between the mrev 2 alone, the 5/16 isothermal spacer alone or the 2 mods together???

my actual setup is 05 vq35de with K&N typhoon, UR pulley, berk hfc, tanabe y pipe, tanabe exhaust, JWT clutch/flywheel, cusco RS lsd and 4.083 fd, stillen etd

I will be getting a tune next summer and I use my car as a dd and for drag racing... Will I gain more hp and lbs/tq with the 2 plenum mods together with a tune or will it be a better choice to buy the 5/16 spacer alone??

please help me to choose what is the best mod for me

 

If you have the non-rev up motor, youre better off with just the spacer

 

but with a tune the combo of those two mods should be able to make more hp than the spacer alone ??? Does someone try it ?

 

See this link to an independent test on a NON-REVUP engine.

I already saw it but it doesn't show what gain gives the spacer alone vs the spacer + mrev2. This is what I really want to see...

 

You mean like this?

Below is a comparison of Stock Vs Spacer Vs MREV2 Vs Spacer with MREV2. All of this testing was performed on a 2004 G35 Sedan with the non-revup engine.










Note: Wired24/7 also made another detailed post about his independent test. I don't have the link off hand, but it had additional details on his results. Try to search for it. It has good information.
