i have read many threads involving my question, yet i still find myself very confused.

so i have an '05 6mt coupe and i am really interested in Tony's Motordyne products. do i need all three of the mentioned products? or just the MREV?

thanks guys.

 

Everybody knows what I like. Funny how some others are starting to look very similar.....no? What's that cliché' about a form of flattery?..............

 

It all depends on what you're looking for. If you want more grunt in the low to mid range, then the MREV is for you. However, and Tony will not deny it, there is a loss at the top end, say above 6300rpms. Even with the loss, I plan on installing it myself.

But one cannot discuss the MREV without at least mentioning other plenums. I don't know if the APS Tallboy has been tested on a revup or not, but JBX loves his(he has an 04 X IIRC). There's also the crawford plenum, and there are even some claims(no links immediately come to mind) that the crawford, without the combination of the 03/04 OEM lower collector, still showed good gains. However, at this time, there's more empirical evidence backing MREV's claims than the crawford plenum on the 05 6MT.

So, what do you want? Do you want top-end? A couple of z guys have said that they won't go with the MREV because of the loss of top-end. It's still up for debate it the loss of the top-end is offset by the gains elsewhere.

In the end, you need to do more research, and ultimately, it's your car, your money, so it's your decision.

 

thanks for the reply. i believe that the MREV is what i'm looking for. after all, most of my driving is done in the low to mid range rpms. i'm still wondering however, if i do install the MREV, will getting the 3/8 spacer help me? or is it the same thing?

 

The spacer is part of the MREV so you will already have one. Trey can let you know more on the subject post Christmas - I am forcing him to wait and actually open it Christmas instead of getting it early.

 

^^^ Which just means that it will be another few days before I can get it installed. Everyone knows how christmas day is, especially when both the wife AND I have parents that are divorved *and* remarried. And we have to visit grandparents as well. Makes for a busy few days.

Needless to say, I know I have it, and I won't be allowed to even look at it until Dec25th, which means I won't be able to install it until prolly around the 30th.

25 more days...

If would be super-cool if I could wake up christmas morning and go drive it. Who else thinks that would be cool?

 

looking forward to seeing your results. so your wife got you MREV?! WAYY COOOL...best gift ever! way to go trey's wife!

btw...i'm looking on the motordyne website and they have Iso Thermal Mrev, Copper Iso Thermal Mrev, and MREV plus....is there much of a difference? which one did you end up gettting? and did you get the extra gasket accessory as well? sorry so many questions.

 

The MREV includes the iso thermal gasket by default I believe. This option includes a coolant control valve that when open allows the engine coolant to reach the throttle body to prevent it from freezing. With the ccv, one would turn it off when temps reach 55 degrees or greater(can't remember the exact threshhold). The Copper option does away with the ccv, but instead uses a copper liner or gasket(can't remember the specifics) that mounts to the throttle body. This option allevieates the need to manually adjust the ccv when temps change or when going to the track.

And as far as I know, the mrev plus's lower collector has runners 1 & 2 machined a bit further.

Tony, if I am off on any of this, please correct me.

To my knowledge, I have the basic mrev option; ccv, no copper, and no machined lower collector.

 

That is correct. We will machine the lower collector after you get it open. If you play your cards right you can probably get that done the day after Christmas. Oh and you ARE NOT GETTING IT UNTIL CHRISTMAS - so stop asking already.

 

Excuuuse me???? I have not asked a single time??? confused

 

Let me refer you to post #6 in this thread and point out the "veiled" attempt at asking. Let it go and we'll talk about it at home.

 

The MREV comes with a 5/16" plenum spacer, as does the ISO Thermal gasket and the CCV (Coolant Control Valve) . The only option in the MREV package is whether you want the "Plus" option or not, which is a modified lower collector/lower plenum or the regular one. I opted for the modified lower collector . . . I figured what the heck.

 

I still don't understand those guys debate???? The MREV gets you to top speed faster....Lets just say if you have a high top end , but a weak middle, you have to go through the middle to get to the top. Now if you lose a little in the top , but you get a lot more in the middle, you will reach top speed quicker with less use of up top.

I will be testing this in the spring....after looking at my multiple dyno plots, I will be chnging my shift patterns to see if losing the top affected anything at all. It seems that the proper shift point for my particular car would be @6250rpm.....after that the HP starts to decline, in other words you are going faster slower. Now if I shift @ 6250rpm's it will put me right back in the meat of the tq and hp that I will be going faster...faster. Does that make sense?? That will be the test anyways.

 

Makes a hella lot of sense to me . . . But then again, I don't boldly go into the realm of top end either.

 

I like the way you think. +2
