he might possibly be saying that the OP closed the thread because of the two trouble makers..

 

i read the thread before it got deleted, it came down to ocg35 g35_tx and one other getting pissed because they were all asking them to prove the validity of the tbs. ocg35 ended up calling a few members names because he couldnt come back with anything else

 

Big +1

 

Not even remotely close to reality.

I am not going to do an ounce of information about this TBS. It simply isn’t worth it. It is on my car, my car does very well with the mods I have chosen - all with a ton of research... but what works on my car will remain my knowledge and a few friends.
I won't ever test a product and report results in an open forum again. There is s ton of information about the product tested including dynos. It has been reported on Driver, a little here, on a couple of FX forums and a bit on a couple of other G/Z sites. I simply wasn’t going to pull all the info from multiple people together to appease a couple of trouble makers. They do the same thing all the time. Instead of reading up on all the info (not just the TBS, multiple types of mods), they sit behind their computer and insist on a post that summarizes everything – even though it’s all been said before). I simply don’t cater to people like that. The reason the Driver thread was deleted is because it went so far off topic it defeated the purpose of the review.

There are particular members on driver that will debate anything and everything no matter what the subject is… and 95% of the time it is not from personal experience but from reading what others have said and done. Then they re-print taking things out of context and getting facts skewed… in the case of the TBS they completely ignore the multiple positive reviews and continued on 1 just ONE less than favorable opinion of it.

I really don’t care what people think about the mod, honestly I’m done referencing it. But if anyone wants to refer to me or what my involvement of the testing, please be certain your facts are clear.

 

I wouldn't say that it's flaky, considering the plenum spacers are doing just that, adding more volume and thus allowing your engine to breathe easier behind the throttle plate -

I strongly suspect that a TBS would yield 2-4 hp and tq on the VQ35, but real world application and dyno testing would be needed

 

the plenum spacer increases air volume after its stabilized, where as the tbs is supposed to spin the air after the throttle body which wouldnt do anything since it would just get smoothed out on our design

 

if you dont care why bother posting that you dont care...no on here is going to coddle your vagina here like they do on g35...you got called out on that thread and you couldnt come back with any argument that proved it worked, want to by a tornado as well i heard those work too

 

don't start crap in this thread too please.

listen OCG35. you can provide information if you want or don't. it's pretty dick not to if you have dynos graphs or an explanation from a designer on why it would improve power or response.

I certainly don't get it but am not opposed to it.

 

Spacers add volume where it's needed - at the front two cylinders which in stock form don't receive adequate air flow due to the restrictive angled upper plenum design.

Sorry, but adding less than an inch extended on the throttle body neck won't do anything. Save the vortexes for the ebay turbonator ripoffs.

2-4 hp.. Please... I could bust *** in my intake and make more power than that.

 

it's quite simple guys - if I were to provide the info I personally have it would put two respected viable sources at odds against each other (actually 3)... I know them all and simply won’t be in the middle of something like that... as for why I don’t do the legwork to dig up the other dynos that other people have done on their own? Why doesn’t someone else do that? I simply don’t care about proving anything to anyone. It's not my product, I reported everything I can and if someone wants more - get your little fingers busy and start typing... as to why I responded here - someone PMd me to let me know this thread was here - frankly I would not have said anything if it weren’t for the fact that my name was being tossed around with mistruths.

Stop badgering me for info about gains. I don't care if anyone wants the damn thing or not. People that have them can comment about their impressions - those of you that don’t have one... have at it - create all the drama you want.

 

hmm - considering 2-4 hp is coming in at a price tag of around $60-$80 dollars, it's not a bad deal. Plus since your all *who-raw* about the forced induction application you would actually yield a benefit from a throttle body spacer. Having an area to tap for independent vacum source is always a nice feature. Plus, I certainly never claimed the vortex or spiral design would work, thus why the one I make isn't with that spiral in it.

 

wow, you are a whiney *****. stay out of this thread and off this forum. you have NOTHING to add.

bye, and don't respond... do like you said you would and post nothing.

 

+1 That's my understanding too. The plemun spacer allows more air into the intake runners. I can't see what the advantage of a TB spacer would be other than additional vacuum/ boost ports... But if someone can show gains with a TB spacer, I'll buy one~ :-)

 

yeah, the swirl idea was brought by someone else, I just mentioned it.

 

Difference is, a rifled TB spacer won't introduce any restriction, whereas a turbonator will.

Not saying it makes a huge difference, but a rifled TB spacer *could* make a measurable difference

 

LOL how the opinions on this mod differ between my350z.com and g35driver when the engines are the same. As a Moderator on g35driver, I still have access to the thread that was deleted by OCG35.
Here are some of the dynos that "prove" this mod works posted by GTO-Dave


OCG35 claims to have dyno's of 10hp gains when he did testing with Tony from motordyne. Tony attributes the gains to ECU corrections from multiple consecutive pulls. Basically he doesn't want to post them because it would put DaveO and Tony(Hydrazine) at opposite ends of opinion on the subject of the TBS.

 

The atomic clock couldn't be more accurate.

 

But as a ChemE, fluid dynamics principles will tell you that if the flow through the tube is laminar, the parabolic shape of the flow profile and the no slip conditions at the boundary for such a small piece would have almost no twisting affect, and if it did, the effect would only change the flow profile in the outer few layers without changing the flow in the center where the majority of the flow is occuring. If the flow is already turbulent, then "rifling" won't mix anything better.

 

*Raises hand*

I am one of the two "e-thugs" and "troublemakers" from g35driver.com. According to OCG35 and SOLO-350Z, I don't believe any modification works for the VQ35 hence the reason why I have a 5/16" MD spacer on my G35 and will be buying the Uprev reflash soon and that I don't "test" mods even though I did at one time have the GG 12 wire kit and Borla TD, both of which didn't work as advertized.

Okay, so now that's out of the way, in the TBS thread that OCG35 deleted, a chemical engineer and myself discussed fluid dynamics and how you can't spin air like the TBS manufactuers claim. The rifling will only cause turbulence along the leading edge of bore. I even asked my powerplant stack engineers if spinning the air was possible with rifling and they laughed and said no way. They went on to say they'd be extremely rich if they could get such a thing to work because it would revolutionize stack and regenerative themal ozidizer design. OCG35 could not or would not provide the data to substantiate the claims made by the vendor and DaveO with regards to the rifling of the spacer.

As for dynos, an FX35 owner submitted his before and after dyno in the thread. It was not stated if the best before and after dynos were being used for the comparision, but the spacer dyno did show about a 3-4whp gain from from 6000rpms to approximately 7000rpms. Using his dyno plot, I calculated out the average gain of power across the powerband (4500-7000rpms) which is what accelerates the car. The calculation was done using the numbers for every 500rpm increment across the powerband. The average powerband gain was around ~1whp.

It is very intersting to see the difference of opinion between G35driver and this site when it comes to modifications for the VQ35. According to my searches, 350Z owners tend to think things like UDPs, grounding wire, intakes, and TBS are a waste of time and money whereas G owners tend to believe most anything works as long as a reputable shop is selling it.

*edit - redlude97 beat me to the punch*

 

soo.... 350Z owners are cooler is what you are trying to say?
