now what has changed besides the machining of the lower collector (which is the inside, correct?)

-Sean

 

the part that is machined im' assuming is the ports on the lower plenum. just comparing at least my stock '05 ports to the MREV lower plenum, the MREV has much wider/longer ports.

 

no, this is not what im trying to ask. Tony specifically specified that if you had a non-revup motor and you added a 5/16 spacer it would be the same as adding a mrev to your car. Not that its the same in terms of power, but it would basically be the same exact design except it would all be one instead of the lower plenum + the 5/16 spacer. So the mrev and the mrev 2 are different in terms of how the inlets are designed...? I want to know the design differences i know its machined for better air flow, but what do you mean by machined??? Do you mean the way the air inlets are designed, the depth of the plenum, or what?

Paraphrased from post #20
you really should call Tony... it doesn't look as though you're getting the answers you need here.

 

Your not allowed to talk about the design of a product? That doesnt make much sense, but i guess i will talk to him.

-Sean

 

With regard to the MREV(lower plenum/collector), regardless of which generation of MREV, it is essentially the exact same lower plenum/collector as with ALL non RevUp Engines. The said was simply remachined at critical locations to afford better air flow for the RevUp ('05 thru '07 equipped with 6MT) engines.

 

Now you are posting fabricated statements/questions... I never said anything about being "allowed" to do anything. No offense, but you seem to have selective reading... Or possible I'm not making my points clear. So as to not further confuse the issue or get any more misconceptions about why I "choose" not to address what Tony has done - this is the last post here from me.

 

Ok this is what i have been saying, now as far as the "outer shell" is it the same? So simply if i took a OEM lower plenum added a 5/16 spacer to the lower plenum (so it would become one peice, use your imagination) and then machined the "critical" areas i would then essentially have the mrev2, yes or no?

That's it, in a nut shell. It need not be any more complcated than that. Back in '05, I installed Tony's pre-release Motordyne MREV+ with a 5/16" plenum. To this day, I have been very pleased with this set-up.

How this particular thread has lasted this long in the Sedan Section and has not been removed and relocated to the "Tech Area," which is where it belongs, is beyond me. This is an excellent example of why threads/posts have been removed and relocated.

 

I said I was done posting but... Andy, you are adding to his confusion. Re-read his question. He is insistent upon getting someone to tell him an MREV2 includes a spacer... and you just told him "That's it in a nutshell"... which apparently is exactly what he wanted to finally hear - however, it just isn't true.

An MREV2 does not include a spacer. It is a modified lower collector and nothing more... it can be (and in some cases should be) used in conjunction with a spacer - but the spacer does not make it an MREV2... he seems to think an MREV is the collector but the spacer makes it an MREV2... anyway, attached is from MD website. If you order an MREV2 you will not receive a spacer unless you buy a spacer additionally... they are 2 separate items and combined they do not equal anything other than an MREV2 plus a spacer - which is a great mod in many cases... and is also what I've been saying for the past 6 hours.

So to answer your question Nismo… yes if you modify your lower collector the way Motordyne has you will have an MREV2 – but adding the spacer is not part of the equation… it’s additional. You keep insisting on lumping the 2 together to define MREV2.

 

OCG35, i dont think you udnerstand my question. I am not saying that the mrev2 includes a 5/16 spacer....haha i dont know how to put this without actually showing you...

 

Ok, does that picture make sense as to what im trying to say or is that what you thought i was talking about the whole time?

-Sean

 

I think you might be overcomplicating it... you don’t need any added depth, space, or anything to the non-revup lower collector to make it an MREV2... just the machining... as stated before, machining simply helping airflow, not adding more depth or anything like that... so you're theory of adding a spacer, in anyway shape of form to create an MREV2 isn’t correct.

Think of it this way - an MREV2 ONLY has aluminum taken away... NO aluminum (or any other metal) is added.

Does that help clarify? If not, I really am done… and wiped out… I can’t believe it could possibly be so convoluted.

 

IMO, i really think you are just thinking way to complex and that you are making it more convoluted. Im not trying to be a smartass and say your wrong and im right as to im not sure if im right (does that make sense?). I just dont think you understand exactly to what im trying to say. Look at my 2 paint pictures and see if it makes more sense now.

 

again, nothing is added to the lower collector to make it an MREV2... only material taken away. So if you start from scratch with your OEM non-revup lower collector nothing more than taking away (not adding) of material would be done to create the MREV2.

MODS, please move this to intake, exhaust where it belongs... this might get better explanation there. So far only misconceptions here...
