what will gain the best power on a 05 G35 6mt with the rev up motor???

crawford V5??

Altered atmospheres spacer?

or motordynes mrev iso kit???

jsut wondering im in the market for some sort of intake plenum or spacer but not sure on what works best with the rev up...thanks in advance

 

Crawfart V5 plenum should provide maximum performance after I watched their video clips: http://www.crawfordz.com/plenum.htm

Correct me if I'm wrong because I want to know this too!!!

i wonder if its better to use this with the 03 lower intake or 05?!?!??! im jsut not sure if this was discussed before...didnt find anything thru search feature...

 

the search feature on this site is tricky.... from what i understand there the crawford and other such aftermarket plenums have just about the same effect on the different years... the MD 1/2" spacer is supposed to create the most gains according to Tony's site... I will be testing out the 1/2" spacer this weekend in comparison to my kinetix plenum and possible both. I wont be dynoing bc idk where to dyno around here, but I'm hoping to feel the difference. the difference between stock and kinetix is amazing

 

I just put the crawford v5 on this week and it's great, a noticable difference from stock

 

Crawford's plenum is the basically the same as the 1/2 spacer. If you're running 05-06 lower plenum, switching to an 03-04 lower will give you some more ponies. You could also throw on Tony's MREV2 and get it all. It all depends on what you want to spend or how many ponies you care to have. Hope it helps. I plan on running the Crawford with Tony's MREV2. I have a few things planned and I need time to get to the dyno. I will post results!!!

 

mrev2 with 5/16!

 

^ +1 ftw

 

i ordered a motordyne but sold it

 

so most people are pretty much agreeing on the motordyne kit? thats what i was thinking...i can pick up a crawford z plenum used for $200...is it worth it tho to put it on my 05 6mt???? or should i jsut get a spacer??? i think spacers are more money than that right? i dont know i just might go ahead and get the crawford plenum so its a easy take off for when i go 2 the dealer with a problem...

 

what about the mrev, 5/16, and the crawford!?

 

Tony says this combo won't do anything for you.

I have the rev-up engine to, so adding a spacer or the Crawford will give you gains but not the ones posted at Motordyne. That's with the non-rev up lower plenum (what Tony call the MREV2 lower collector). As far as taking it off and on when you go to the dealer...... the Crawford is probably easier but with the spacer you can still keep your engine cover on. That will make it hard to see, but if your mechanic has to remove it, he could notice it. But it's your call. You can't go wrong with either. Just remember what I said earlier...... The Crawford will act like the 1/2 spacer.

 

so it can work and it is compatable? to my knowledge the non revup lower collector was the mrev+ and the revup was the mrev2....the dealer has seen my 5/16 spacer numerous times and i also gave them the heads up about my mrev. nothing to worry about there unless the mrev causes my engine to blow

 

so is it agreed more gains come from crawford plenum with Mrev2 on a revup engine?

or is the mrev2 with 5/16spacer better for rev-ups?

or a combo of all 3? which is best?

 

i think the mrev 2 with the spacer is the best combo but all the spacer does is lift up to accompany for more air to get in and that is exactly what the crawford piece does.....
