first off, thank you hydrazine, performance nissan, and klumzee for my mrev+

i was just wondering if it has been determined whether or not an aftermarket intake would help the mrev+ enough to justify the cost. Or wheather i sould spend my money on a more cost efficient performance mod.

i have read a lot of different stuff about intakes, and some even rob power and the ones that don't seem to produce very little. I don't care about increasing induction noise.

 

Just throw on a z-tube and modifiy the stock aix box....now that's a cool noise it makes then

 

I don't know what your set-up sounds like at the moment. However, installing a Z tube and a new free flowing drop-in filter, such as a K&N or Amsoil, will definitely open your MREV up. Enjoy your new mod.

 

mrev is the only thing i have. i really don't want to do something for the sound. like i said, sound doesn't matter to me. i wanna know if anyone has experience of mrev w/out intake as compared to mrev w/intake.

 

ok, so i've read a lot on different sites, and it appears that some intakes actually don't play well with the spacers. I am thinking either the stillen, the popcharger, or the stillen combined with the popcharger filter. Havn't decided if i wanna spring for the z tube since it seems to just add noise. I am also probably gonna wait on MD introducing their new intake, before i make my decision (any estimated release date on that?).

So till then, i wanna hear more about the performance interaction between intakes and plenums (especially the mrev). Again i am not interested in sound.

thanx

 

The Z tube, Stillen and Popcharger are all good choices.

 

thanx tony. i guess that narrows it down for me. do you think the z tube actually does anything performance wise?

 

I must admit I was skeptical of the Z tube untill I saw a pre/post dyno of it.
It made 3 HP. Now this is about within the range of dyno error but it was consistant for 3 pulls.

For $50 to $75, I say go for it.

 

so i read this thread on my350z that a guy added a 5/16" spacer and felt no gains. then he added a popcharger and all of a sudden he felt a lot more gain than just the popcharger alone would merit. i would go with the popcharger but i read on another thread that intake temps with it are 4 degs higher than ambient temperature. (and i don't like the design of not having a box).

so i was thinking maybe the effect of the mrev corresponds to the level of tune, particularly the intake being used. so i am trying to go through all the mrev dynos and figure out what intake they were using. Tony, if you happen to have some data about this, i would appreciate the help.

one of the original dynos was from a guy name alex. what's his forum name?

 

If we are refering to the same Alex, he was the first to dyno the MREV+. But I don't know his forum name.

He had a "no name" hot air intake (HAI) that sucked hot air right out of the engine compartment. It was pretty bad. But despite this, the MREV+ made the gains shown in the second plot of the big MREV thread.

Then the majority of the other MREV plots have been on a range of stock to highly modified vehicles.

 

i have no doubt that mrev makes a BIG improvement on any car. i'm just trying to see if certain mods play better with it than others, looking for a synergistic effect.

yes, that was the alex i was talkng about. His HAI might have been sucking hot air, but he made a huge improvement, bigger than klumzyee i believe. The no-name intake was probably able to suck more air.

 

What made Alex's dyno plot different is that he had the MREV+ rather than the regular MREV.

As for synergy, the Z tube is a good option. Maybe coupled with a Popcharger or Stillen for a little more juice.

 

so read some more stuff on some more forums, seems like the jwt requires you to do some drilling? is this correct? can anyone elaborate. in any case, the whole intake thing is starting to wear on me. i like the jwt filter design, i don't want it to suck hot air like the popcharger and i wanna keep the price reasonable. At this point i'm really starting to think drop in filter. but the design just seems so restrictive. another idea that keeps popping into my head is buying a $20 cai off ebay that connects right to the mrev. this would eliminate the need for the z tube and if i get even 2 hp with it, it's much much better hp/$ ration than a Z tube + k&n for maybe 5hp at a price of $120. i dunno what to do. its frustrating but fun at the same time.

 

I have an o5 6mt Sedan. I'm thinking about a Stillen Z tube and a drop in K&N filter. How will it sound? Will I see any rear wheel hp? All the online specs are from 2003 (260 hp motor). I'm wondering if there is any sound or rw hp increase on the 298 hp motor?

Thanks

 

Agreed

I noticed the same thing, albeit with the 5/16 MD spacer. Now that the HKS is on, it's an entirely new beast.
