EDIT: This is a REVUP

I decided to see if the MREV2 did indeed show an improvement over the MREV+ that I had installed.
The MREV2 arrived from Tony well packaged and I noticed additional machining over the MREV+.
I did have some aluminum dust from machining which I cleaned off using soap/water and drying immediately.

The swap was performed on the dyno per Tony's request and the engine temps were kept the same.
After doing the swap around 5 times, I had no trouble exchanging the lower plenum.
I did a total of 6 runs, 3 before, 3 after, with an ECU reset (pedal method) before the 1st 3, and the last 3.
I would like to mention that the run was done until the engine hit the rev-limiter so the last 500rpm or so drop off is really outside the normal operating RPMs.

In terms of the "Butt Dyno" I do see improvement around the midrange-topend.
It pulls to the top harder than before. I highly recommned this upgrade to anyone looking for more NA power.

P.S. Yes I know one of the plenum spacers was not installed when taking the picture.

Here are some of the Dyno's for you to check out:

 

sikc video mang.......

 

Thanks for posting. Very consistent pulls with a slight edge to the MREV2 in the mid and top ranges.

 

great vid rob........great numbers also.........who did the dyno, and how much was it???? admins should sticky this thread

 

Dyno's were done by Billet Design Motorsports in Pompano Beach.

 

Sweet! Nice job. I still have to get mine done.

 

yup... mrev2 does kick some butt

it was a great experience working with Motordyne/Tony... if only other companies offered that kind of customer service

 

Great post!!!! This is what forums should be like!!! Proof!!! Not hype!!! Anyone want to sell there MREV+ PM me. Yes MREV+ not MREV2. I want to try something. Great Job Rob

 

any sort of engine management? Im worried about doing both spacer and mrev2 without any sort....

 

^ +1

Great job, and thanks for posting dyno's.

Am I reading the A/F chart correctly that the Mrev2 actually improved the A/F ratio slightly?

No Dyno here but my 2004 MT Coupe with Mrev2 added after 3/8" spacer is stronger in mid-range pulls..

 

I'm not technical enough to decipher the AFR. Anyone can shed some light on it?

 

Although it pulls harder, sometimes slightly leaner = more power, its just that in the wrong condition or just a little bit too much WOT will make you start knocking...
No engine management for you?



coming from a turbo car, I would only run in the 13's, high 13's I guess would be OK, but Its pushing it from 5800-6800 the A/F slightly worries me. I know that the dyno runs richer correct? Theres less load on the car right? I don't know about non turbo but it would worry me sorta.

Higher number = leaner. So 14-15 is leaning out. not super lean, but under WOT u probably don't want that. Under 12 is rich.
