TB spacer
thing.
I didn’t "bring up rifling" - DaveB did... and the "Vornado" is a fan and air purifier that has a design to "curve" airflow...
If you are too lazy to read what has been said over and over again here and in the other threads - or just plain too stupid to comprehend it, then you are a lost cause. But there is no reason to go over it yet AGAIN! You’re too late for the drama party, which is to bad because I suspect you are no brighter than the last guy that got called out.
Do us all a favor a stfu – we already went through all this.

Function Tuned. I added headers and a kinetix v+ plenum on top of my 5/16 spacer and picked 13.5hp and 20tq.
No the plenum does not rub the hood when closed with the spacer. The last time I did this I had MD's old 3/8 spacer and it rubbed.
I plan on getting a used SGP VB and 3.7 gears soon. So my stillen will be up for sale.

Careful of SGP... you read the thread on my350Z right?... its in the same area as the RA thread that you posted your VRT experience on... I'll link it if needed. Since the unit you are gettig is used, it might not seem like an issue - but for future troubleshooting dont count on SGP... I think you'll like the shorter FD! I guess I wont be faster for long
Not to get into this argument but Mike, wasn't it you that contended that it was the rifling of this particular TB spacer that you suspected made this one "work" and the others not? I don't see why you would go to great lengths to argue the merits of the rifling if it was a moot point of contention.

This entire topic is so worn out – I’m totally done discussing it. I’ve stated everything I know and feel about it many, many, many times here and in several other threads. If anyone is interested in what I think about it, just read.
Any further comments towards me about it or questions to me regarding it will go unanswered. Don’t post all kinds of rhetoric about me not responding because I’m telling you in advance I have no interest in continuing the drama and simply won’t respond to further inquires.
Mike. You made a contention and then shot down the guy questioning it. I even question it here:

It's clear that the rifling inside the TB spacer is what you directly contribute the gains. And if I understand correctly (since you are very unwilling to clarify), it's the rifling that helps the airflow through the turn in the intake manifold. Now again, whatever rifling there is, I contend it does next to nothing as most of volume of the air is flowing inside the spacer and only very little of it is flowing or touching the rifled edge. In order to alter airflow significantly (like your air purifier thing), it would have to encompass a much larger area of the TB. I mention the boundary layer concept in that thread.
And Tony's reply :
But post #85 is great. I would have started any reply to these TB threads with that one and proceeded

I just got off the phone with Shawn Church (owner of Church Automotive Testing)… he indeed did dyno a prototype TB spacer… he confirmed that it dyno’d about 8 hp on the upper end (5500rmp range)… I asked him in theory what could possibly be the cause and he explained that the one he testing had rifling on the inside edge – you have to install it one way only… it alters the airflow in a way – unlike the Tabulator that swirls the air prior to the TB and does basically nothing, this apparently helps the airflow make the turn on our curve (from TB to plenum)… he said it did nothing on cars that have a straight intake/TB to collector.
So in theory it’s not the added volume, it the altered airflow helping the air flow around the curve after the TB.
Seems a little hokey, but I fully believe Shawn. He wouldn’t state false claims of gains. I asked about clearance (he ran a 7/8" spacer) – he has stock intake tube and said it fit but the accordion flex was collapsed all the way.
I don’t know if all manufacturers have the rifling – it looks like AAMs has functionality more for adapting other components – the rifling one might be worth looking into further. I tried doing a Google search and there are tons – so I’m not sure which one makes this particular TB spacer or if it’s even production ready… I will start researching some of the others though. Now that I know there is something other than added volume (which in theory is a bogus claim) it might be worth it?
Edit: the spacer is 7/8"... Shawn thought by recollection it was about 3/4" that's what I originally posted - after receiving the product and measuring it I have corrected the size in this post.

I carefully tested one myself on the Z and it did nothing up or down.
I can't comment on what Shawns results were, he told me the same thing. And Shawn is credible... so I seriously looked into it. I just didn't see any effect in my testing... and if I saw even 1 verifyable HP, I would have researched this subject very heavily.
But I won't say no just yet. If any one wants a free pre/post dyno of their TB spacer just let me know.

Those posts aren’t even form this thread Jeff… re-read what I said… I told the guy here that I never used that term “here” and that I never said anything about it altering airflow in the combustion chamber.
What does posts from this thread vs that thread have to do with anything? They are all about the same thing. I've already explained why you think the rifling works and it had nothing to do with the air after the intake bend.
Just direct people to the thread I posted (and was probably reposted) and leave it at that.

The apologies should be coming from those of us that took it off topic with the drama and debates... for that I'm sorry (to you).
Did you order your maf yet from Z1? I have mine already just waiting for Dave to fit me in his schedule.
Let me know when you go for your retune I might can meet or roll with you there.

Dave is a busy man. I am getting my os giken clutch installed, but had to wait till the 25th (and I made the appointment on tuesday) for him to have an open day. Good luck to you guys.
I recommend you guys come up for the next meet on the 28th.......it's a bikini car wash meet for charity=full of win.
