I might try to get a mrev2 to add to my 5/16th spacer now that i know it doesnt serve the same purpose. Toy around with it and my AFC II a little bit see what we can get out of it.

you're welcome... good luck - let us know what you come up with.

According to this thread, if you have the non rev up motor and you add the 5/16th spacer you automatically have the same thing as the mrev minus the better machining for air flow...so all in all the 5/16 spacer is the same thing as the mrev except for the lower collecter that is machined for better air flow...

-sean??? im confused now haha

MREV = non-rev up lower

MREV+ = machined non-rev up lower

Yes, I’m aware of that (that wasn’t a sarcastic voice either), but what i was trying to ask earlier is isn’t the mrev the same thing as the non revup lower plenum and a 5/16th spacer hypothetically speaking. So the example that i was trying to give is that if you were to weld or mold a 5/16th spacer to a OEM lower plenum then essentially you would have what is called the mrev...right?

To me thats what it sounds like tony was trying to say in my last post...

Jeff read OCG35's post on page 2 and mine..doesn't he say that the mrev 2 and the 5/16 are completely different things? I mean yes they are, but essentially they are not since the OEM lower plenum and 5/16th spacer are all in one.

So what i was asking is since i already have the non-revup motor and a 5/16 spacer would it be any use to replace the oem lower plenum with the mrev2 since all i would be doing another 5/16 spacer basically? Hypothetically speaking wouldn't it do the same thing as just adding -2- 5/16 spacers to my OEM plenum? (minus the machining of course_

MREV in any form doesn't = 5/16" spacer. Not quite sure where you are getting this

So what i was asking is since i already have the non-revup motor and a 5/16 spacer would it be any use to replace the oem lower plenum with the mrev2
Benefical? From what I read yes.

since all i would be doing another 5/16 spacer basically?
No.

No. Spacers does not = MREV2 IMHO anyway.

Isnt that what he is implying here though...? That if you have an OEM plenum with a 5/16 spacer it is already a mrev though...

You are confusing MREV, MREV+ and MREV2... I addressed each.

What is the date of Tony's post you are quoting?... I suspect it was before he even started doing the MREV2

Original MREV was the nonrevup lower collector for the revup motors... I have stated this MANY times today.

Ok i thought i read that the only thing that changed between all of them was the machining for air flow...isnt the mrev 2 the same thing as the mrev except the fact that the inlets are redesigned for better air flow, but the other outside molding stays the same...

EDIT: i really am sorry about all this i have heard so many things then i read something else and it makes everything that i had read fall apart.

yes, MREV2 is a modified MREV - modified by machining the lower collector for better airflow... as it pertains to your needs read the post I made about the benefits of each...

Don’t be sorry - you are asking the right questions, you just don’t seem to be understanding the answer I keep telling you... ad far as what you have read previously - there is a lot of quack talk out here about what it actually is... I've seen it a million times. Some people post definitions that just baffle me.

Honestly, you have such a continuous flow of questions and seem to be a little reluctant to latch on to an explanation; I highly suggest you give Tony a call directly. He is a great guy, obviously knows more about it than anyone – and has some of the best customer service I have experienced in any industry ever. He will help you understand and give you answers you can count on.

yes it machines the lower collector, but as far as the outside mold its still going to provide a 5/16 space over the OEM plenum just as the mrev did correct?

spacer has always been a seperate option... never a required part of the MREV line. Yes, a spacer fits over all of them the same.
