Review: Motordyne E370

370Z JT

Yea Buyer Beware! You couldn't believe how shocked I was when I saw the results. And then I had to pay Tony the $1,600 after the testing just revealed NO GAINS! What just happened here? Did I just spend $1,600 for a nice smooth curve?

The Z community should know the E370 did not make any more power than the Invidia Gemini on my Z. Bottom line.

Tony provided you with the logic behind your installation and tune and you continue to ignore it and cry about peak whp gain on a NA CBE INSTALL. Did you honestly expect a huge jump in power going to another aftermarket cbe???

Huge jump? No. I would have been happy with ~5hp gain. We're talking about Invidia Gemini CBE...not Stillen or Fast Intentions.

As for Tony saying the baseline run with the Gemini was tuned for AFR and timing and showed a lumpy curve. The tune I had for the baseline included the Motordyne M370 manifold which I removed from the car 2 weeks earlier. Could this be the cause for the lumpy curve? Did this cause the Z to lean out a bit? Look at the AFR baseline. It was running lean.

If the Invidia baseline was re-tuned do you think the curve will still be lumpy? And if the Invidia baseline was re-tuned, a few more HP would have been squeezed out. How would that make the E370 look then?

Just a few points the Z community should consider.

Edit: I also had a blown 3-bolt exhaust gasket for the Invidia baseline runs. LOL

So what you're saying is, the test wasn't good because all these things changed beforehand?

LOL, i think at this point youre just trying to piss the OP off. He spent extra money to have the car dynoed before and after the install and shared the experience with the community. I dont think it could've been done any better than the OP had.

It's very apparent that youre a Motordyne fan boy and want to defend the exhaust. That's fine but there's no need to be taking it out on the OP.

The baseline runs for the Invidia Gemini wasn't good because all these things changed beforehand.

The power numbers for the E370 would not change. It is what it is.

Most manufacturers will generate and advertise their own numbers and then shy away from independent testing or comparisons. We don't.

Most won't build a data base of independent tests on a public forum for public distribution. We do.

There is nothing to hold back or hide. We'll do our best on our side and encourage independent reviews and testing. Even yours.

More independent tests and comparisons will be done over a range of conditions by various people and they will all be posted for everyone to see.

Thank you for doing the dyno testing and review.

Unless Tony told you his exhaust was going to make a decent amount of power more I think looking for a gain going from one aftermarket exhaust to another is just silly. I picked my FI because of quality and looks, all exhaust in this price range make around the same power.

these are "high-end" exhaust systems and you are paying for the superior sound, quality of the product and customer service. it seems OP has experienced the "intoxicating sound", and commented on the "superb" quality of the product, and Tony was present during install and now is here helping him with any concerns and questions he has. sounds like he's getting his money's worth if you ask me

I can assure you i'm not trying to annoy the OP.

It sounds like he's already annoyed at not getting what he was hoping for and i agree with you, i don't think it could have gone any better than it did.
However, as i pointed out, he's complaining over a few HP at the top end and yet he already admitted the base tune wasn't very well because he altered a major intake part without changing the tune just weeks before this.

It was already stated that these are both open exhausts, they're isn't going to much much in the performance of a completely open system, it's going to be down to sound, quality and looks, which he's happy with.

I do like Motordyne products, but i can't defend something based purely on that. I, like everyone else, can read what's been posted, i was just pointing out an inconsistency of the same level it's being complained about for the power. He seems quite upset that it's the same power as before, with a smoother curve and better sound, not to mention if it was tuned again with spark advance, he could get more power.

But like i said, he still seems quite upset over it all, i'm just pointing out he shouldn't be so, when he didn't do the fullest possible in the circumstances.

MaDMaXX

No, i was pointing out that if he's wanting to show changes of a few ponies, then everything would need to be perfect. The intake was changed before the test without re-tuning. The re-tuning after the MD wasn't comprehensive, it was missing spark advance.


I'm only reading what's been posted here, i don't know/have any other info, but from what i've ready, those are the inconsistencies, and i think they're enough for a few ponies difference.

*Baseline tune not matched to installed hardware.

*Re-tune not comprehensive enough to include spark advance.

*Resulting peek power was the same but with a smoother power curve.



Just calling it how i see it from the info here.

W.O.W. 370Z

Too many dyno queens on this site...

I just think your expectations were too high.

Ages

I thought motordyne was present for the install and dyno? They should have insisted on a comprehensive tune . Then this would not even be a discussion..( provided it actually showed gains that is)

+1 good summary of what's been reported in the OP's review.
