Review: Motordyne E370

shaun66

Theres a resonated option correct? How long are the resonators?

Motordyne

The resonators are 16". The resonators are also available with built in catalytic converters.

Both are in production now.

Good review!

red6spd

So wait I'm confused? Does MotorDyne say this exhaust will make more then others?

Motordyne

No, but we do encourage fair and independent comparative testing.

G37sHKS

Oh trust me that im the one who's confused not you and here is why

1st) Motordyne said in the past that they are making an exahust for VHR that nobody ever saw such a design/exhaust before, and after they release the E370 it looks just like all the exhaust produced for 350z/G35 coupe by Motordyne

2nd) Tony also said that E370 exhaust will produce the highest gains out of all the aftermarket exhaust... but the E370 was having hard time beating Invidia in this thread...

So... think again.. who's the one who should be confused now? LOL

modme

Wait what? Nothing in your post explained why you can be confused but no one else. Wwhat? Dont get your logic.

I agree with you g37sHKS ... I was not expecting these kinda results from Motordyne .. I have patiently been waiting for this and to see these kind of results is a huge let down .. It is not a design that we haven't seen before. Almost identical dyno compared to what I would say is a inferior exhaust "Gemini" compared to the e370 . Just really not what I was expecting ..

Yes but this one is not ready yet.


Where did you see this?

MaDMaXX

Are the resonators available on their own? and if you ask for cats, is it cat and resonator? or just cat?

Based on the above, both are available together?




Also, guys, read what Tony replied with, this exhaust got exactly the same results as the other straight through exhaust, but it was less stressed with the Motordyne (had more power to be made)

Once you're straight through, there isn't much that can be made, it's down to sound type and level, however, as Tony already explained, this car has a very smooth power band, whereas it was lumpy before, indicating this isn't a super stressed tune on this exhaust, whereas it was before with the invidia.

Remember guys you pay extra for the quality/sound/power. Motordyne a exhaust is exceeds the quality of invidia in welds/looks/customer service and sounds sexier(IMO but it differs from person to person). I'm still eager to buy one but a resonated version. Because I daily mine. You guys have to stray away from the dyno queen peek number bs and look at how smooth the power band is and how it would most likely be a lot better exhaust for those thinking of a s/c because that exhaust has the potential of making more power. But would like to see it compared to other exhausts.

Not looking at the peak numbers .... It is what it is ...

Yes.

and if you ask for cats, is it cat and resonator?
Yes, its a combination of the two.

Yes.

While it will show similar results for NA, it won't be hindered at all in forced induction applications. The Shockwave))) allows more headroom and versatility for forced induction because of the modular and progressive expansion design.

If you were to install a turbo later on you won't need to buy another exhaust to accommodate it. It will produce excellent results with no changes needed up to the ~500-600 HP range.

Shockwave))) covers both NA and most turbo applications because of its design and modularity. It certainly has more flow capacity than a dual 2.25" system.
And in many cases, in the 5 PSI-12 PSI range , the E370 overall performance will be better than either a full dual 2.5" or full dual 3" exhaust.

The Shockwave))) E370 is unlike any other exhaust in that it hits the sweet spot for both NA and most FI applications.

Motordyne

Here are the same runs plotted in their respective groups and a little more clearly.

These are the spark timing and A/F tuned baseline runs. They are inconsistent and lumpy which indicates it was tuned to the power limit and running on the edge of ping.




These are the A/F only tuned Shockwave))) post dyno runs. A near perfect overlay. They are very smooth and repeatable. If these runs were tuned in the same manner as the baseline runs, it would have made additional power.
This is actually a perfect tune. Although more power could be made by advancing the spark timing, you don't really want to push it beyond what you see here. The engine is very happy with this tune.



Here are both sets of runs overlaid. This shows the relative difference in set to set repeatability.



The pre and post dyno runs were in different states of tune.
