Hey, I could not get enough pics of this before I got mine. I'll install it tomorrow... will take pics of the 06 revup lower collector when I take it off so you can see the differences...

Installation should be a snap! Have fun with it and congrats!

 

Did you get the Mrev2? That looks like the Mrev1...




















Lol..jk good luck with your install! bwahaha

 

ya! mine should be coming soon. post results and pictures

 

Hey, that's not funny... I was like "WTF?"

It's too early and I have not had my brefas yet...

OK, that was pretty funny...

 

I just installed my motordyne MREV2 and 5/16 spacer. It took me 2 hours with the help if my brother. Just a tip, I had trouble reinstalling the strut so i shortened it 2 turns to make it fit. After driving my car with only a pop charger and the mrev2+spacer I can barely feel a difference. Let me know how it turns out for you.

 

You can barely feel it? have you reset your ECU? Are there any leaks that you have notice around the engine? If everything is good to go, then just let your ECU adjust to the new mods. Also, do you have a revup engine or 287 engine?

+1 on shortening the strut bar, I had to do that also.

 

Make sure there are no leaks first, if it does, your idle should be off. Then disconnect the battery, and pump the brakes a few times (I stepped on it like 10 times). Connect the battery and drive the car. When I first installed it, I didn't do the ecu reset, just the battery disconnect. After I did the brake pump method, I felt a huge difference. Good luck!

 

hiz-n-herz. wheres your review at? haha

 

ok I just got back from the mazda driving event and my car isn't at home. (my brother must have taken it out for a spin) Ill try pumping the brake. I have an 06 and I already disconnected the battery. thanks for the advice guys.

 

do all 05's and never have the rev up motor.

 

nice... I want one!

 

If you are unsatisfied I'm sure tony will give you a refund, that's his policy...

 

My understanding is that the anniversary edition '05 6MT had it , as do all the 06 6MT Z's. the autos are not rev-up.

 

Well, let me say tha this install was the biggest PITA that I have ever tried to do . I'll post pics when I get home tonight.

Basically, it all went well with one exception... those f-ing nylon spacer caps that are supposed to "snap" onto the support posts on the upper plenum. Only 4 of the 6 fit on as I expected. The back left and right posts DO NOT FIT. The back right post took like 20 minutes of wrestling to get the thing on there. The back left one would not go on at all... period. I had to cut the plastic off that is supposed to fit around the post. The spacer is round and the post (back left and back right are oval or egg-shaped. IT DOES NOT FIT. Friggin pissed me off! Is there a new upper plenum cover on the 06's that motordyne has not seen or considered? perhaps... So now that I cut the outside edge of the nylon spacer off, I was able to get it on. Luckily it has that little lip pf plastic inside the bolt-hole that grabs onto the bolt. I really don't like this post-cap spacer design... it makes me nerveous. If I took it to a dealer, I'd have to revert back to the original gear. I'd be afraid that if they did not take it off just right, there's a potential for the plastic spacers to come off and fall into the intake manifold. Even on the ones that I did not modify. If I were designing it, I'd have the plastic spacers attached to eachother via some kind of metal retainer to make sure there's no chance of a spacer falling into the head via the intake manifold.

Then there's Pinging.. Yes, wonderful pinging...

Before mrev2 and spacer:
With warmer weather (65 degrees plus) and at RPMs below 3000, if I eased on the gas, it would ping for a bit and then go away above 3000 RPMs. in colder weather, (55 and below) it would ping very little if at all.

After mrev2 and spacer:
In warmer weather (it was 77 on Saturday) it pings like hell all the way up to 4k rpms. To be fair, I have not installed the coolant bypass yet. It took so long to get those planum cap spacers to work I was pretty tired of it. But damn, it pings badlly. then at some point in the upper RPMs, it feels like it detonates or somehting... just a single really loud ping at sround 4500 RPMs. Kinda scarry!

In cooler weather (Saturday night, it cooled down to 55 degrees) so I took it up onto highway 84 from foothill to skyline (locals know what I'm talking about ). Here it performed as advertised:

Power curve before: (Butt dyno with two-cheek correction factor) Car felt a bit weak below 3000 RPMs. from 3k to 4k, you'd start to feel power coming on. from 4k to 5k power leveled out and at about 5500RPMs, power would surge up to redline (if I could stand to rev it that high due to vibrations through the gear shift). So the moral was, if you wanted power you could feel, keep it above 5.5k rpms. also the engine did not seem too willing to rev past 4k RPMs (IMHO). Just didn't sound happy.

Power curve after: Below 3k RPMs I can't tell any difference and the thing pings here even with 55 degree ambient air temps. Actually have some decent power building from 3kRPMs and rising steadily to 7krpms. Before, it felt like it had some flat spots in power. After, there are no flat spots. Plus the engine seems much more willing to rev. If you keep the engine above 4kRPMs, it really pulls and there are no flat spots. Power builds in a much more linear fashion. It feels better than last time I did that run (hwy 84) and my wife was in the passenger's seat this time.

So, for me, when it's cold out it is definitely a good mod. I may revert back to stock and take the car in for pinging. But last time I took it in for pinging, they said it was normal. Maybe I'll just take it to an independent shop and have them dyno it and look at a/f ratios.

I don't think it's a night and day difference. The differences are more subtle than that. remember, if best-case is even 10 HP and 15 Lbs of torque, and only at certai RPMs, then that is still only a 4-5% difference overall. Where you would notice it is mostly on the track (or twisty roads) where you might otherwise be be caught in a flat spot in power coming out or a corner or something.

I do remember a couple of evil laughs and grins on my Saturday night drive...

Again. I'll post pics tonight of the install problems I ran into...

 

Unfortunately pinging is pretty normal even for a stock motor and no mods. The mrev2 and spacer leans you out a little bit below 4k rpm too.

You'll be fine with regards to pinging. For best results (performance and pinging) get tuned.

 

I had the same problem with the plenum spacers. (2 of them) I took a metal file to the back-left most post till the cap just fit on. I also used a rubber mallet to lightly tap all of them on. Unfortunately, when putting the upper plenum back on, the back-left spacer dropped off and I wasn't about to disconnect the hoses and start filing again. So I just removed it and am running with 5 of the 6 spacers in place. It definately tacked on a bit of time to my install.

 

OK, I updated the pics above so you can see the difference between the 06 revup and the MREV2 lower collectors.... REVUP looks like it can flow a lot more air. The runners are shorter and more circular and look to have more area overall. Of course they are the same size where the collector meets the intake manifold. But this is all about tuning and who wants peak power at redline with less torque in the midrange? So on with the MREV2!

Here are the pics of the PITA end caps that I hate. There's got to be a better way! They would not fit on one of the posts...

Hmm... Doesn't seem to fit


Wow, not even close!


Maybe I'll stretch it out...




Still not even close. There's absolutely no way! I cut off the lip to make it fit...


Is this a new upper plenum cover? Or is this the one Motordyne engineered their stuff from? I know it'd be a PITA for Motordyne to engineer another part, versus off-the-shelf hardware. But I would not recommend this install to a marginally mechanically inclined person due to the tough, if not impossible fit of the plenum spacer caps...

One of the guys here said he left the spacer out. I would not advise and it seems this would increase the chance of vaccuum leaks in that area...


Hope this helps someone...

 

Good write up..but I am wondering if you have got the defect part..
If that cap was issued to everyone else, how did they do the install?
+1 on there should be a better way to make that cap to fit on.

 

I kinda had trouble with those caps too, except mine were too loose! It kept falling off the posts so I screwed in the long bolts through the upper plenum into the caps to hold them while I put on the spacer.

It should even out though, I just kind of scooched it around a bit until it was all level. It should be a straight forward install...but as always there will be problems.

Talk to Tony, I'm sure he'll help you out.
