I have no doubt more power could be had with a tune, however, one will never know how much of that power is from the tune and how much is from the mods.

This is true, but the Customer in this case did not have a full understanding of what the outcome would be. And he seemed very dissapointed in the results.

Patronize? I don’t think anyone knew what the outcome would be. I had my hopes, as you said, my little experiment. But I can say this, as I said it after Crafordz cats dyno:
This aftermarket industry is blooming because of fools like me, but hey I am learning.
Maybe you will have more success.

Sorry for raping you with many bytes of my dynos

could it be that dovla's efforts have shown us that the performance improvement the 1/2" spacer or mrev2 provide is the max amnt that can be had, the upper limit, without add'l tuning? if that's the case, i'd take the mrev2 over the 1/2" spacer cuz its totally stealth, and you can retain the oem strut bar.
to dovla, when i bot my brand-new 03 back in 02, i was one of the guinea pigs testing a completely new model, and i, too, have been a guinea pig for new z mods. sometimes the mods i've tried have performed as advertised on my z, and sometimes they haven't. either way, i post my results for the benefit of other members of the site, and i have benefitted from others' guinea-pig adventures here. thanks for sharing your experience with us.

But in Dolva's case the heat transfering properties did not help.


Exactly. I just said in my post above it won't make a difference on the dyno.

And I just wished manufacturers would better explain these things to people before they take their money and sell them a product.


So you throw out completely false and baseless assertions? I encourage skepticism but you better have some basis in fact before going out on a limb. I've explained in multiple posts what iso thermal is and does. See the link that has been in my sig for months now.


I think had you explained to Dolva, that this modification would offer him NO LEGITIMATE GAINS given the current configuration of modifications he already purchased from you, he would have not purchased it.

Now you are talking trash because you don't know what our conversations were. After the $100 rebate, Dovla only paid $22.00 for the part. I offered the rebate in exchange for publicly posting his dyno results because this configuration has never been dynod with a previously installed 1/2" spacer. That's being open and honest. Ask him yourself before you come up with the genious idea of calling me a liar.

If people asked me how much gain it would make I couldn't quantify it. I expected it would do something (even with a 1/2" spacer), yet I always said "take it to the dyno!" Its fully documented.


Sooner or later it had to happen. I've seen you write wild eyed frenzy with so many other respected people on this board. People who instigated nothing with you and you had no basis or need to troll on them. It was more of the same speculation.

Both times the car was allowed to sit and cool for aproximately 45 minutes prior to the first run on each set of results.

Thank you. Exactly the point. No heat soak to evaluate the effect of the Iso Thermal. You aren't catching on...

If an open hood dyno does not measure real world HP then why do you post dynos for all your products?

For deltas in plenum geometry and the resultant change in fluid dynamics. Even if the absolute values arent accurate, the deltas are. Thermo dynamics however is completely independant of fluid dynamics. If you need this explained... there is limited effect in trying to explain anything to you on an engineering level. You either can't understand or don't care to hear.

Why not post some technical data like intake temps?Or Track times?Or datalogs of the engines vitals?

You obviously arent reading. I posted the results of an array of (objective) thermocouple data above. My measurements = 30-60 deg F. Independant = up to 80'F with a average of 50'F. Heat transfer analysis based on thermocouple soakback data, plenum assembly mass, plenum aluminum specific heat capasity, plenum temperature change rate, air mass flow rates and air specific heat capascity at constant pressure show the reduction in heat transfer is good for 2 HP under heat soak conditions.

Should I break out a full analysis for you? I could do that but it would fly right over your head and you would go right down the same path guaranteed. ...So I won't waste the time.

Dont make a claim of 10 whp then change the topic to debate the effectiveness of an open hood dyno, which is, by the way, the same measurement you utilize in your sales pitch to sell products, simply because the results on someones dyno did not favor your findings...

You are hallucinating buddy. Where did I ever claim or post anything about MREV-2 making 10 more HP when added to a 1/2" spacer? I always said wait for the dynos of anything that hasn't been previously tested. You are thowing anything out to see what sticks. When you hallucinate, you lose credibility.

2 hp at the track, YIPPEEE!!! Or I could slap on 2 Type R badges and gain 5hp per badge..lol Cmon man, your talking to an avid drag racer and performance shop owner, not some 18 year old fast and furious junkie...2HP is nothing and can be elated to an inconsitancy in the car

No problem.But 2HP is 2HP more by a method the competition doesn't make part of their kit. If the competition averaged 10 HP to the wheels, 2 more HP on the Motordyne spacer is 20% more power and thus 20% more value the competition doesnt offer. Its that simple.
20% is significant in my book. I'm sure you won't care or understand though. ...Why am I explaining this to you?

However, what I am saying, is that the addition of the lower plenum with a 1/2" plenum made no power.

I've never disputed it. It's OK. It is what it is.

But, you used that to launch into several other points where you are completely wrong and have no basis in measurement or fact. You have no analytical skill to support your assertions. Your assertions are incorrect.

I've seen you persistantly rail into others when they had nothing to say to you and you had no reason to gouge them.

What your saying is that the fact that the 1/2" plenum spacer is 3/16" larger than the 5/16" one, that the lower plenum mod does not make great gains with it..So the lower plenum only magically works with the 5/16" spacer then?

You seem to be sticking to the assertion that the machining process doesn't work. Is this true? Are you then disputing the test results generated by NNA and Wired 24/7?

Based on your track record and writings in this thread, its aparent to me you don't really care. You made a blanket assertion that the plenum machining process doesn't work. And you seem to be sticking to that assertion. You're wrong about the maching process and you are wrong about Iso Thermal.

What Dovla and I wrote to eachother doesn't really mean anything to you. Persuasion based on reason or fact are irrelavent at this point...

Selectivly twist, ignore, speculate to false conclusions and hallucinate as you please.

You are completely correct in the fact that I am not an engineer and dont understand certain physics of what your talking about, but I never claimed to be as smart as you..But your response seems a bit out of line, with the name calling and insulting my understanding of the factors at play..I did not call you a liar, I am simply debating with you the effectiveness of a particular product you sell.Your books and calculations say it works, my experiences said it did not..Thats all I was debating, but you choose to assault my character as a result? Thats not cool at all man..
I was just trying to clarify some of the claims I have been hearing by you in the past. When you reffered to the open hood dyno, I simply thought it was strange seeing how you use dynos yourself to verify gains..Thats all..Geez, sorry if you took it so personal..

What do you expect?
You make false statements about my product and that in turn assults my integrity. And no, I don't particularly like it.

Be skeptical. But don't throw out assertions unless you have some real evidence.

Come to think of it. The reason I am sensitive to it is because I don't want to be like many of the other manufacturers.

They pile on the garbage so thick its disgusting. And I dont want anything to do with it.

I want to make only what works and I will do my damned'est to make it the best.

EDIT: Comming from an aerospace background the technical and ethical standards are way higher than here in automotive. Its not even comparable. So when I become established as one in the automotive aftermarket manufacturing industry, I feel like i'm swiming in a industry of muck.

The science is a lot of fun. Driving fast cars is fun. Research and development is a lot of fun. But much of the industry makes me want to blow.

And I am a realist and a skeptic..There are ALOT of manufacturers out there that cliam BS like 25 whp gains using their product. I have been modding the 350Z since it came out, and we have alot of experience on what works and what does not work on the car..I was making a GENERAL statement about manufacturers who make false claims, not specifically reffering to you at all..In general we have seen a consistant 7whp average gain from both spacers and full plenums..

Did I misunderstood concept of PM?

I only wish that there are more companies out there like MotordyneEngineering
