Throttle Body spacer

There are plenty for all mods on this car. Theoretical evaluations frankly do nothing for me in determining a particular mods value.
Here's the link - it really should be considered.

I'd be all over a throttle body spacer if the gains were consistent. It's just very odd that some cars gain power while others don't. The fact that a selling point for the spacers is the rifling/vortex effect raises a huge red flag, IMO. Air isn't a bullet and rifling isn't going to improve velocity, flow direction, etc. It's physically impossible.
I've driven numerous Gs over the years, autos and 6MTs, and I've never noticed dead spots anywhere, other than on my G when I was experimenting with various intake designs. I did find that the more open you make the intake, the worse tip-in throttle response is and there are some dead spots below 4000rpms. With a mostly stock intake, the dead spots aren't there.
I guess if the mod makes someone happy and it feels to them that it's added power, then I guess that's good for them. Seeing that the dyno testing is inconclusive, Tony at Motordyne has tested it and he said don't waste your time, and there is no track data, I have a hard time believing the spacer is nothing more than a chunk of metal. To each his own.

Take the time to read what I linked and then I'm open to an intelligent conversation about what I posted.

Tony concluded that TBS aren’t worth is based on his version that he beta-tested. However, when multiple dyno pulls on my car with an entirely different TBS was tested at his facility, there absolutely was gains! Tony feels it was the ECU playing tricks (to the tune of 10hp) Quite honestly, I feel it has to do the TBS. I respect and value Tony as a professional and as a friend – but our conclusions are different. Furthermore, other dynos have shown gains as well and indeed some haven’t
DaveB, until you have done as much real world research and testing I suggest you have a more viable declaration than “I just don’t think it works”.
As stated above, you haven't any real world experience so anyone that would make a decision based on a statement like that is foolish IMO.

I'll always up for an intellegent debate, but you're the one that usually gets pissy.

If you guys have truely tested the spacer and you're a proclaimed 1/4 mile racer, why isn't there any 1/4 mile data? The spacer can be put on within 10 minutes so why not do some before and after runs? These cars are incredibly consistent on the strip....unless mine is some sort of freak. I'm consistently within .3mph and less than 0.06 seconds assuming similiar 60 foots. My friends 03 5AT sedan was the same way. Testing a mod like this would be extremely easy and the trapspeed differences would show if power is gained, lost, or not there. What's so hard about that?

We didn't design anything. Read the pages and pages of history and you will have a better idea of what exists. Research the threads here and on my350Z and you will find all the research data. Until you have a clue of what you are talking about - I won't bother with you. Oh, BTW, no I won’t reiterate the 5 months of activities for you because you are too lazy to look it up.

dave why dont you just buy one and try it out for yourself? its less than a hundred bucks and takes max 20 min to put in. if you dont like it just sell it. im sure someone would pay somewhere around 80 bucks for a used one. you wont be out that much money. this might be one of those mods that dont show up on a dyno (like the pulley), but i just think until you have tried it for yourself you cant really comment on it. people can go on and on and debate about it, but the opinions of those who dont have the product should be nullified.

As for the UDP, if it really worked, it too would show gains on the dyno and at the strip. I had an UR UDP on my old VQ30 and it didn't make a lick of difference on the dyno or after numerous 1/4 mile passes.

So, if the information is really out there to prove that these things work, then why don't you post up for other to see. What's so hard about that?

I could not find any other threads about TBS. On this site, the only that gets pulled up is your TBS thread in the Review section. As you're well aware, I have been involved in that thread which you've turned into a Group Deal thread and have basically ignored many of the technical questions regarding a TBS. So, forgive me if the search engines on both these websites aren't great, but I simply don't have the time to scan through 1000s of threads.

Dave - if you aren’t interested in a Throttle Body Spacer fine. Who cares? But why the uniformed, un-researched posts?!
Enlighten yourself, read the FIVE MONTHS of activity before you keep embarrassing yourself. I don’t care if you agree or disagree with the findings – you have not been a part of any of the developments that has gone on. I do/did, however care about each and every one of the beta testers that had a keep it or return it participation…
Stop with your non-sense for a change. Go find something that will provide a positive attribute to this forum for cryin’ out loud. You are every mans nightmare – a nagging b!tch with nothing worth hearing.

For explanations why the spacer in the GB works on the VQ - read the research chronicled in the post above.

What's interesting is that the same claimed principles for the TBS closely match close claims made by the often flamed Tornado intake device. People laugh hysterically at the Tornado, but these TBS seem to be more viable.
