Got 'er done! Motordyne M370 installed
 

So last month I bought the Motordyne M 370 intake manifold and just this weekend I had the time to do it.I had worked on cars since I was a kid , but in '78 when I went to med school, my automobile tinkering came to an abrupt halt.Any work on new cars now has a leaning curve.
Friday nite I get all my tools together,and get to work. I get nearly all the bolts off when I get to the two long bolts at each end of the manifold and I can't find my deep 12mm socket, damn and I wasn't going to damage the nut with an open wrench.So I button everthing up and decide I'll go to Lowes in the morning.(I called it a dry run and felt good that it all went back to normal and the car ran fine).Saturday comes , I get the tool and go back to work.
My wife walks into the garage and asks "what are yoou doing to the car?"
Thinking quickly I answered "I saw some feathers here (which I did only one )
and I want to make sure that there isn't a dead bird in here"( things like intake manifolds fall under "need to know" and she don't need to know)
As Motordyne stated it only took a hour to do, so now everything is done and the moment of truth comes, I push the start button , the engine comes to life, sounds really good and best of all no check engine light. The idle was sorta rough while the ecu adjusted itself to the mod, then purred like a kitten.
I took it out for a short test drive and I felt an instsnt difference, what a kick inthe pants.It feels so good to be turning wrenches again. BTW when I was done the missus asked me if I found any more bird parts in the engine bay.
No just a few feathers.(thats how you stay happily married after 27 years.:bowrofl:

Nice. Seriously thinking about getting this. Any other engine mods you have besides this?

Thanks for the fun post DrEvil, I'm glad to hear the mod made such a difference for you; once you add the tune to the manifold mod, you'll probably be able to squeeze more hp out of it. I enjoyed at the feather story :bowrofl:

So far I did an R2C cai, Tanabe cbe and I have the Tanabe Y pipe on order.

Does the wife know about those? haha

Cool. Glad to hear you're enjoying it!

Need to know only, she does't need to know. Damn I put a cai and a cat back on her XC70. My grown kids noticed it right away, especialy the beefy exhast tip and the different exhaust note but she don't know.:bowrofl:

LMAO @ mods on the Volvo.

That's awesome.

Positive results with the Motordyne manifold? Possibly a placebo? I hope you actually did get positive results. Many people here haven't seen enough of a performance increase to justify the costs.

LOL congrats on the install. Even tho I heard not much on Motordyne. LOL my wife notices all my mods from exhaust to accelaration. shes say Did you do anything I say no ,shes like car feels different LOL..

I should be getting my Motordyne M370 installed in the next few weeks, along with a Uprev tune. Glad to hear you enjoy the mod!

Hilarious story DrEvil!!!
I love it that you're happy with the mod, and that the wife is "on a need to know basis". I keep my wife on a need to know basis too, I was able to do HPS tubes + K & N drop in air filters with out her noticing, I know easy. lol, Know i'm hoping she doesn't notice the F.I. res test pipes + CBE come this June!!!

Wife must be deaf to not notice the exhaust getting louder LOL

I am soo tempted to to fi but with the car missing for a week or so, that she would notice, so therefore she would need to know.

Pretend the car got stolen. When the work is done just tell her the cops found the car! :tup:

Won't work that way. Way too many law enforcement personel in our practice.
Here comes the big test, with the weekend just about over we'll be heading back to Jersey. The gains with the manfold are in the midpange so thats about highway speed , right?
I 'll see if my missus notices the change and btw I saved a feather.:bowrofl:

Haha....:icon18: Enjoy the mod, I know I do.... the midrange should be the most noticeable in terms of power.

absolutely if you gun it, you feel the surge in the middle that otherwise just felt like a linear acceleration.

Just got home and yes indeed ,the mid range is up there . Was doing 75 and went to pass a lld(left lane ****) and before I knew it, I was doing 100. I'm sold on it.

A quick follow up on the install, DON"T pay someone to do it for you, it's way too easy to do yourself.I would have done a dyi on it but I had to get done before the missus figgered out what I was up to.The instrction sheet is quite clear and the only tools needed are 10,12,14mm regular and deep sockets and a pair of chanel lock pliers to open the hose clamps.The only issue is/are the pvc hoses are just a touch too short so you have to play with them .The last thing is that on the stock manfold the manfold vacume sensor nipple plugs right into the manifold, on the M 370 it plugs into a hose. Since the nipple is kinda short you really have to convince it to stay put and get the hose clamp set just right, if not the car will stall. Other than that, no problems at all. You really feel an increase in power in the mid ranges,accelleration is much smoother. I don't race, so peak hp doesn't matter to me but as a dd it kicks not to mention 28 mpg on the highway.As larry would say "git 'er done" and I add, by yerself.:tiphat:

Nice write up, But I would like to see is there are really any gains( Dyno) For $650 better be something.. I was looking at this also but wait for results..

Wife+ Need to know is my thoughts also..

Dynos here:

http://www.the370z.com/intake-exhaus...-manifold.html

Thanx but wanna see a independent dyno.

There are three independent dynos linked at the end of the first post.

I saw those, But hard to read.. The Dynojet ones I never take for real. To many factors can scew the numbers the mustang dyno makes no sense 269 WHP 301 WTQ?? (YEA RIGHT) I have used a lot of Mustang dynos and none of mine are that tuff to read.. LOL

I still want to see more than three, and no in the Motordyne thread, Just a guy who bought it and did before and after runs. I would but the $$$ is too steep for my just to grab it and try..

Nice writeup

I will be throwing mine on the dyno shortly with plenty of 'pre/diff' dyno runs to compare it to..

DrEvil -- any idea on vac hose diameter/size, I think I will go get a few feet in prior to install to route them with slack etc.

Nice man, Will be looking forward to these, :tiphat:

sorry to bring up an old post but i was just reading through and Drevil you are the king!
just have one question, can you put the plastic cover back on after the new manifold?

You can the top part will stick up a little. You can always adjust that.

No problem at all! Went back on without a hitch.

I was about to pull the trigger on this a few days ago but after some research or should say others stories...it seems that the more bolt ons the less power you seem to get...dont know how that makes sense but thats what i have read. And in my situation i have FCB, hfc, cai, and im afraid i will lose the power i have sole greatly dedicated much time and $$ into.

I'm going to do more research and maybe something will change my mind..

any input or thoughts are appreciated as well....not stealing the thread of coarse...lol

From what I've read it won't give u more overall hp, but it'll give u more hp in the lower and mid range rpms (where most people do the majority of their driving) so for me at least this in on my list of future mods :)
