Ongoing Review For The Motordyne M370 ...
 

I've had the Motordyne M370 on for a few weeks and I believe that now would be a good time for an objective review. Review that I hope would help peers on the forum make an informed decision about the M370 mod.

First off, I would like to thank Kirkster (Our awesome and always willing to help MidA Expert) for the install; Daisuke, Zcarman & Staples whose highly detailed reviews & positive experiences were a major factor in my purchase decision; B1ades for assisting Kirk and entertaining us during the install; last but not least Tony for an exceptional/professional product as well as customer service.

At the time of this initial review, I haven't pulled the official dyno numbers yet but will be doing so soon ... hence the "ongoing" review ;) Now on to the good stuff.

Purchase Process/Delivery Process:
I purchased the M370 during the "Osama got his butt owned by our seals" promotion (Hoorah!); though abroad at the time, Tony was prompt to reply to my concerns and made sure that I had the unit nicely packaged & delivered as soon as I was back in the US.

Installation:
The installation process of the M370 is fairly straightforward for any mechanically inclined individuals and with all the appropriate tools. The second time Kirk did it, it took about 1.5 hour, including the car cool-off time. One key thing during install, make sure to lay a towel on the engine block once the stock manifold intake is out. You wouldn't want anything to get inside the block ... good luck if you do drop anything in there.

Performance/Enhancement:
There was a drastic difference in engine sound once the M370 was installed. The exhaust note is throatier and deeper. The car nicely screams and roars (Please refer to video below for illustration).
I haven't done any dyno pulls however, it is very obvious that there was a huge gain in power specifically torque in the mid-range. The 5th & 6th gears pull harder up to around 7500 (Will get definite number during tune). The car feels more aggressive overall, my lady's and my butt dyno can definitely attest to this gain of power(considering how she swings during gear shifts as much as bowling pin being striked and also by how she gets pushed back in the seat :p). I am very very satisfied with the gains on this front and I am looking forward to seeing how much more power would be squeezed out after the tune.

The Not So Good Part:
As part of an objective review, I have to bring the good as well as the not so good parts. The M370 is truly an outstanding unit that does the job, the negatives are not with the product itself but rather with the documentation for the installation. Kirk and I had to go through the installation twice as we were not aware of the fact that the plate HAD to be installed with the unit in order for the provided bolts to fit. We found this out way after the stock manifold was installed and the M370 set on the engine; I didn't have the plate with me at the time... however, much to our surprise we were able to get a hold of the customer service on a sunday afternoon to get help; that was definitely a good surprise. There were even a follow up call and email to ensure that my issues were fully resolved; those actions further confirmed to me that Motordyne does provides excellent customer service. :tiphat:

Overall Thoughts:
Based on my experience with the M370, I do believe that this is a great mod that most would be pleased with. The gains I experienced are very significant and I will be providing an update once I get the tuning done. I hope this helps sway your decision with the M370 unit. :tup:

Great review man! I think you've convinced me to put this on my list of mods to get for my Z :tup:

Can't wait to see what kind of number Zuperman puts down on the dyno after getting tuned. Call me whenever you are getting that done, I want to see it in person :tup:

Thanks man, glad to hear that. I am anxious to see what the numbers would be too, definitely enough for zuperman's take off :p No worries, you would be the first one I call when I bring the car in for tuning ;)

im sooo torn on this too, why do most people tell me this is for F.I tho? woulndt anything be an improvement over the stock platicness

nice car tho dudde!

Awesome bro! Any idea when you're getting it done? I've got a set of G3's coming in sometime soon. Trying to keep up with you is kind of hard :p :tup:

Great write up, can't wait to hear this in person, hopefully Saturday.

Zuperman can stop a hurricane, right? :p

Thanks for the kind words dude. I sat on the sidelines for a while over this mod before making the decision. I got some great gains off of the mod AFAIK, I don't see why it wouldn't be the same for you ;) There are a few members on the forum that have the M370 on their F.I Zs but it is not only limited to F.I, N/A also get great gains out of them (Zcarman, Staples can definitely attest to this with actual numbers to back it up). This is a definite improvement over the stock manifold.

LMAO, I'm having a hard time keeping up with myself :p great deal with the G3s man, that's going to sound/feel awesome on your Z. I'm thinking sometimes in the fall for the tune. Temperature-wise it would be better then.

first off great write up I know this took some time, Pics and vids are AWSOME nice work.. BUT
In for Dyno numbers. The numbers I have seen are hit and miss. Some guys got good gains an others got little to nothing. With that said I'm probaly not going with this but want to see what side of the fence you are on. :).

Saving for GTM 15% Saved.

Only thing with the dyno numbers is, we will only see what his final numbers are with all his mods + tune. We won't see the gains from any individual mods.

Thanks Lou ... hopefully Saturday ... depending on what Irene dishes out ;)
Thanks ANMVQ. There is no doubt that the dyno numbers will put to rest some doubts about this mod and I agree with you regarding the few hits and misses though no one has been able to explain it yet. I definitely feel a huge gain in torque throughout, but more so in the mid-range, which is in line with what those on the gaining side had... I think I'll be on the winning side of the fence :p

Hey sounds good that you pulled the trigger on this mod and decided to do a review. These are my questions. List of your current mods? What are you sitting at power wise now with those mods? Do you have a tune done already? What is the butt dyno numbers of changing out manifolds? I would be interested to see your current numbers matched with new manifold vs OEM. Then after all that obviously the numbers after a tune with the M370. Not trying to bash you or this product at all just looking for more concrete information rather than you "feeling it". That phrase reminds me of the sprint booster thread which was a disaster. So on that note thank you for trying this out.

List of mods is in his sig. Hasn't dyno'd or tuned the car set so no actual numbers. Butt dyno I think he mentioned in his review was good. Don't think you can put actual numbers to a butt dyno though, that's just dumb. That should answer all your questions :tup:

Thanks Shahid :tup: repped for helping with the answers. That pretty much sums up your questions V8 and no worries, never thought for a second that you were bashing anyone. I noted on the Manifold thread that you are simply trying to get as much info to make sure that you get the best value should you invest in the mod... perfectly understandable to me ;)

Oh BTW Ryan, Staples and Zcarman had some actual numbers from dyno pulls which should be close to what I'm probably getting. The difference with Zcarman is that he had a tune previously done prior to getting the M370, I didn't.

sub'd for dyno results...

sub'd for YOUR dyno results. You promised :p

I think Tony's company is top notch, there are just mixed reviews on this part it seems like with a tune that it doesn't make any power... or very little. Maybe they have found something out. I know the ART pipes are FANTASTIC on my car, so I would imagine the m370 would also work very well.

I think it makes more mid range power than max power in the top end, from what I've read.

Based on the other dynos as well as the ones from Motordyne, the gains are throughout the entire power band with the most significant gains mid-range, mostly in torque. This is what I'm experiencing with the unit :tup:

Thanks for the input Methodical, don't forget to post up your vid with the ART pipes ;)

:bowrofl:

Will be dynoing soon...

Oh it's up man... on the intake/exhaust thread... maybe a few pages back on my ART pipe review.

What he actually meant was don't forget to show up at the MD meets with your ART pipes :tup:

yeah, i'll get there at some point... getting married soon... got a lot to plan for :tiphat:

Congrats man! If you ever find some time, feel free to stop by :tup:

oh yeah I definitely will at some point, just not sure when.

congrats man! :tup:

How could I miss that? Congrats, it gets only better from now on (despite what others will tell you) :tup:

Thanks for the videos about the Art pipes & B1ades made the correct translation for me. We are that much on the same wave length :p

Did your NISMO Intake Manifold cover (Engine cover) still fit over the top of this like the stock one? I have a 2013 NISMO.

It will not fit without modification!

I know this is old but did he ever dyno the car?

Nice reviews.

Stock cover fits, it's not flat like stock, it bulges. But it looks great,

Still no butt dyno results?

There's many other threads on this topic, both on the370 as well as myg37. Just need to search :tup:

This was a while ago. Busted 02 sensors on the runs, but still valid. These are tuned results.

Here are my dyno sheets!

dyno sheet of what ??
those you attached cant only be with the M370 as it make no sense at all. unless the car needed a tune badly to begin with ... this isnt a dynosheet as its supose to be with only the M370, yours look like a dynosheet from an exhaust and/or a tune. !
sorry if I sound mean on my comment.


This one from SS Firehawk is the M370
and then mine after with the HR Intake Manifold I cant call it the M370 because I did the same as them but as a*DIY intake manifold*


mine,

I don't take anything on here personally LOL! I guess I miss the M370 only. You are correct in that there were more mods on the car other than just the M370. At the time of the tune, the mods were AAM True Dual 2.5" exhaust, ART pipes and K&N drop in filters. The I think the biggest thing to note about the M370 is that it provides for better torque numbers. Anecdotally it seems to produce about 10ft/lbs more torque than without it. Also, top in whp seems to be reduced by about 5.
