M370A=HomeMade
 

From what I have heard about motordyne they seem to be a very reputable company. The 370z is my first japanese sports car and I really have enjoyed it. There intake will give an honest torque gain but Do Not expect it to be a good deal. The quality of the part is on the NO. Back to the stock manifold for me. ((iDO NOT like the aluminum Plate you have)) That is cheap!!!

Did you put it on the dyno? If you don't like the plate, you could always put stock engine covers on. From what i have seen, 10-15 ftlbs gains in the mid range is pretty impressive to me.

Mine works just great it made all sort of more rwhp and torque between 3000 to 7000 rpm and i did not loose any top end power.
1/8 mile time with it 8.02 @89.3 mph.
12.42 @ 114.3
all motor 7 AT.
i ajusted my tune with my cobb and it really goes now.

I should really try to find a used Cobb for my AT just to compare it to my Uprev.

Hey when you do, would you mind shooting me a PM on that I am kind of leaning towards a Uprev tune but I have thought about a Cobb as well.

so, if i understand your point, you don't like the plate as a stylistic choice. everything else is ok?

The 1/4" aluminum plate is there for a functional reason. It needs it. Do you have an alternate suggestion?

What is this plate you speak of? I never received one when I ordered my M370 intake.

The one shown here: MOTORDYNE M370 Intake Manifold.

I thought u said it was a good mod for the money? What happened?

I could tell a big difference down low in torque and no loss up top. Car continues to pull to redline.

I have M370, Stillen Gen 3, Full 3 inch exhaust, and FI Resonated Test Pipes.

Also M370 changed tone of exhaust, which I like. Loud despite Evo 4G recording it.

Yea I got some power out of it, but the way its bolted to the lower intake is not a good design. The aluminum plate just pushes down on the upper intake. If one didnt know any better they could crack the new intake by bolting it down to tight.

Design a new intake and dont use 350z parts.

:iagree: It would definitely be nice to see Motordyne or someone else come out with a full new design meant for the 370Z. I don't like the mentality, "We can make it fit."

What you mean good deal? Like $$$ wise?

On the other hand, if it works, it works.

Improving flow is time consuming, and that cost gets passed on. This is a good, cheap manifold.

how much more would you be willing to pay for the same performance gain as M370?

I'm sure that a large part of the M370's cost is getting the OEM manifold. I'm thinking you could have a new one molded for less. The R&D would be the costly part.

Maybe Motordyne can chime with more details.

thats going to be hard since Cobb stoped the production on our platform and getting a used one that work on a 2009 370z 7 AT isnt easy..

so going for Uprev right now is pretty much the only choice for you,

Sure, that is 'possible' but it would have to be torqued down really hard to do that. (as in waaay past the stock torque spec.) And the only real objective of torquing it down at all is to compress the soft silicone gasket beneath the manifold. Spec. torque is all that is needed and it will NEVER break.

As for designing an all new manifold, its not a viable or practical business option. The modified stock manifold from Nissan is very well engineered and basically is designed and manufactured with what is effectively unlimited Nissan resources. Such as the tooling to make that manifold. The tooling alone would cost somewhere between $200K-$350K to emulate. Then the piece part price of each manifold would be 2-3x higher than it is now.

With all that put together it would be completely unfeasible from a manufacturing point of view. The best and only practical/viable business option is to modify an existing stock part. Its the only way.

Otherwise, the M370 makes measurable/objective power and torque gains. And that is all it is really for. Power and Torque gains.

there is a manifold that costs over 1k for our cars, looks nice, complete new design, makes nothing in terms of power.

Thats 1k.. for no gains.. add R&D into gains and your looking at 1500.

So the m370 is a good bargain. As much as you complain about dnot use a 350z part... there are alot of parts in our car taken from a 350z or other nissans. Companies always reuse parts in cars, electronics.. anything.

Do you have a clip of what it sounded like before? by any chance?

Its kind of like what happened with the MREV2 that is used on the prior 350Z. A modified stock manifold was used on a newer generation engine and it makes really great gains.

Many companies have tried to design plenum modifications for the 350Z. Anything to squeez out a little more performance... And still nothing comes close (in terms of dyno performance) to the Motordyne MREV2 with the 5/16" plenum spacer.

What I can say with certainty is the Motordyne M370 is the highest value and best performing manifold available for the VHR engine. And it makes appreciable gains.

Let me see if I didn't erase it. I have a prior clip but that was with different exhaust setup.

I have been happy with the M370 so far. My car doesn't spend much time above 7000 rpms, but it regularly sees 3000-5000rpm. So this intake definitely makes driving around town more fun.

Also, Motordyne's customer service is great. After reading my post above, Tony has already contacted me and shipped out the aluminum plate. If only all vendors were so good.

Alright I was hoping to hear the difference you described... so with a different set up it will sound different regardless. Thank you though!

Best way I can describe is deeper and throatier...

Hard to describe but noticeably different.

Other members have mentioned it changed their exhaust tone as well.

yup it did. Deeper is definitely a correct description. More aggressive sounding, but not louder.

very seriously considering picking one of these manifolds up.

Thanks for chiming in, Motordyne. I appreciate when a sponsor/manufacturer takes the time to discuss their products with the forum. Althought it's not the ideal, the performance increase is attractive.

Thanks for the descriptions of the note it invokes, tempting if not just for that... lol

+rep to both!

Seriously, I would just be happy that someone even bothered to spend the R&D dollars to give you anything. If it wasn't for them you would have nothing. If you want to ball out and design something from the ground up then you should go right ahead! (if you think it's a good investment).

Us 350Z HR guys have nothing! :shakes head:

The Cosworth manifold?

Arnold,
Yours is shipping out today. A tracking number will be emailed to you shortly.

Thank you!
Tony

I'm assuming you meant the ART Pipes? :D

Hell, I'll take an M370 on the house if you're feeling kind. LMAO

OP im curious, did you do any research on the motordyne mani?

Its been made obvious its a modified 350z mani to improve power. why did you buy it knowing this then make a thread to purposly tell motordyne not to sell 350z parts?? :/

I had the MREV2 and plenum spacer on my old 350... best bang for buck mods I did to that car. No issues with quality/fitment or install.
