When I bought my 04 6mt Coupe, the previous owner had already installed the Kinetix plenum.
I have read a lot of great things about the MREV mod for our cars and if I understand it correctly those with 05-06 cars are the ones who really benifit from the MREV mod.

My question is this, is the MREV mod on an 04 going to be more benificial than the Kinetix plenum on my 04 or should I be content with my Kinetix plenum?

 

The MREV is for the 298 HP engine only. Unless you hve the 298 REvUp VQ, be content with your current plenum!

 

That's what I thought, Thanks for the quick reply.

 

Or you could switch to a spacer mod with an oem plenum. Motordyne's Iso kit works very well.

 

The Motordyne spacer should afford your G some healthy gains.

 

NEITHER - MD 1/2" and you're good.

 

So the spacer would be better for my 04 than the Kenitix plenum?

 

check out the graph here - its on the MD site, but it is data from sport z magazine's plenum shoot out

Notice how much better the 1/2" is as compared to the 'plenum K' - kinetix and plenum c - guess which one this is.

there's more dynos here: http://www.motordyneengineering.com/dynos.asp

but i think that the dyno from 5000 rpm to redline is the most important because when you are trying to accelerate hard, that's the rpm you are in - which is where you want your mods to help you. The 5/16" gives more power from 2000 rpm to 5,000 rpm. But when i'm in that rpm range, i'm usually just trying to save gass, not accelerating hard, unless i'm in 1st gear. But the choic is up to you.

 

same question here but i have an 05' 6mt should i get kinetix v4 plenum or mrev+

 

i havn't seen dynos of the kinetix on a 298hp engine. but if you find some, compare the gains to the gains of the mrev on md's website (my previous post has the link). i would think mrev is better, but i don't know for sure. i know that a spacer doesn't do anything for the 298hp engine, but the kenetix should do something b/c its essentially changing the entire plenum to the old design and adds volume (kind of what the mrev does, since mrev is just a combo of half the old plenum and a spacer). so, find some independent dynos of kinetix (the ones on md's site are independent, they are all just taken from g35 driver posts) and compare.

if i had to guess, the kinetix might give you more top end, but mrev will give you better midrange and torque.

 

imo, its all so close. if i were you i would stay with kinetix. i really like mine, but i am getting a bit tired of the sound it makes.

 

^^

what sound is that you hear??

 

+1 wut sound??

 

i got the crawford v5 plenum, it rocks especially at high revs
