Just got done wiping down the exhaust, and noticed the driver side "Motordyne Engineering" engraving is upside down. :shakes head:

Quagmire, can you check to see if yours is like that?

I will.
Edited: yeah its upside down.

Which engraving are you referring to? Are they on the resonators?

Yes it is upside down on the drivers side on mine also. looks like they're all engraved the same way

I just checked out lasblueprint's photos and his engraving is not upside down. Although I think he got the very first E370 exhaust.

:icon14:

I just checked mine and my passenger side is upside down

What the heck is going on. LOL

did you guys mount the muffler section with the MOTORDYNE logo facing the ground, or facing the driveshaft?

Isn't your steering wheel on the right? So basically the left canister is upside down.

haven't mounted mine yet but either way they both going in opposite directions lolol

oh yeah sorry hahaha

forgot we drive on opposite sides :roflpuke2:

so yes your driver side, my passenger side

Yes, I think I did….It was a long long wait, but well worth it…..I did have the previous exhaust on my 350z and love the quality and sound…..I have not DYNO’d my 370z yet….I do plan on doing soon, I do have a base line run, a base line run with the M370, but have not ran Dyno on ART pipes along with the E370. I will keep you guys posted with that on my update review on my thread…..:tiphat:

Nice!

Logo facing down

OK good. I just tried to adjust the fitment on mine right now, thanks :)

i was with my 350z buddy who has the original Shockwave this weekend. man, that's one of the best sounding exhausts i've ever heard. it's so damn smooth! i can't wait to hear this one in person.

This exhaust sounds great, beautiful note and tone. BUT, if you do punch the throttle on full blast, you will soon know why it’s called the ((((SCHOCKWAVE))))

I will start taking my car more and more too local meets here in the southern Cali area and do more track days. So hopefully for you guys that want a chance to hear it will be able to hear it in person.

You won’t be disappointed. I’ll continue doing more and more videos for you guys and do more updates on how everything is holding out. So far, I’m happy with the quality and sound.

On a positive note, no hiss on deceleration with ART pipes & E370 as opposed to my previous setup. :tup:

same here :tup:

Retune scheduled for next Tuesday. Will keep this thread updated.

M370 Install
 

Install semi completed today. I will have to wait to get my front strut brace back from the paint shop to complete the install and then I have an UpRev tune and Dyno runs scheduled for next Saturday 3/17.

No base run to check gains from prior to installed mods. K&N Typhoon CAI, Berk HFC, ARK Performance CBE (Upgrading to F.I. 18" resonated #500) & Motordyne M370.

Im glad you had a successful install but this is an E370 review thread. ;)

On another note, I'm having difficulty confirming my tuning session with Church Auto for this Tuesday. They're slow on responding to emails. and not returning voice messages when calling. I will call again Monday.

Yeah, realized it right after I posted. Oh well, just excited!:o

Looks Great.....Keep up the good work....

Any news on the retune ???

I received some interesting results. Will post up plots/vid tonight or tomorrow.

update?

Where is this new info ??

Update: 3/15/12

If you have been following this thread, last week Tony offered me a "more complete tune" by Church Automotive Testing (CAT) in Wilmington, on his dime. Having nothing to lose, I gladly accepted his offer and scheduled a dyno tuning session with Shawn Church for 12pm, Tuesday March 13th.

Tony was certain more power can be realized if both the timing and AFR was tuned as opposed to the tune by Seb@Specialty Z in which only the AFR was modifed.

I arrived at CAT at 12PM, however I was told Shawn has stepped out and would return shortly. At 12:15pm, another tuner said he'll go ahead and get my car strapped in and proceeded with the tuning session until completion at about 2:15pm. I would like to make it clear Shawn did not have any direct involvement in tuning my Z. However, Shawn did come over to the dynapack monitor several times and discussed the data log with the tuner.

Below are two photographs of the results. Green is the Specialty Z tuned map, and Red is the Church tuned map.

Results:

Horsepower dyno plot was identical up until 5K RPM. Moderate gains (estimated 5-7 HP) were seen with a Peak HP gain of 6 HP.

Torque dyno plot showed gains by the Church tuned map at almost every place under the curve. A considerable amount of torque (estimated 8 lb-ft) was gained between 5K and 6K RPM.

I was pleasantly surprised with the gains from CAT. I decided to validate and confirm these gains on another dyno. Directly after the tuning session with CAT, I drove to Specialty Z and had my Z on their dyno shortly after 4PM. Gains shown on one dyno will reflect the same gains on another dyno.

Below is an image of the two maps on the Dynojet. Blue is the best pull for the Specialty Z tuned map, Red is the best pull for the Church tuned map.

Results:
Comparing the two tuned plots, both were strikingly similar. Peak HP and TRQ were identical. The two plots basically over laid one another. However, where are the torque gains between 5-6K RPM? Where are the HP gains after 5K RPM?


Questions/Comments welcomed.

Do you have the dyno run files for both sets?

Wow the two SZ do runs looks similar, but the only factor I can think of is that those 2 runs are a few weeks apart. Not sure how similar weather conditions were between the two days.
I would go by the Church dyno only because those runs were done back to back.

But I'm not one to get hung up on numbers; does the car feel any different driving? And man, these Z's seem to like their fuel.

Edit: just saw your further post below indicating that you tested both maps at SZ that afternoon. I'm stumped

Assuming that, going from one dyno to another should show the same results = absolutely blah false.

Your initial dyno is your best indicator. You cannot even compare that to your initial dynos from specialy z.

The thing you have to look at is, your base run, then your runs after the tune. Any variance there is your gain / loss. Trying to compare it to another dyno from another day, another dyno shop etc = useless.

So based on that, you did gain from the tune. Thats what matters.

You can go back to specialty z every day if you want and you'll see variances in the dyno's.

:iagree:

I would say that is definitely a measurable difference and free to boot! Dyno reads a bit high, but the results speak for themselves. The AFR's look much better as well.

For the pulls on the SZ dyno plots, we ran the Church tuned map then within an hour we ran the SZ tuned map. Same 2 maps, same day pulls just like the Church dyno plots. The delta gains still wouldn't be present?

ahh musta missed that part. there should have been a slight diff there if you indeed saw a diff from the dyno tuning

The SZ tuned map didn't include the cam adjustment, and as the last tune before it was applied (Church tune) did have it, then is that not why you didn't show those changes this time.

You can't adjust cam timing, only ignition timing.

Sorry, transposing them in my head, yes, i meant spark advance, point still remains ;)
