Never said I was fast in general, just faster than you right now as of this moment.
I'll do 3" just for you. I still have the 3" maf made by Grey99max, just need all matching piping and we're good to go.
Where do I find the formula to calculate the proper intake length again?
The 3" will be straight ghetto for testing purposes only... so PVC piping will be used
I wish I had a PFTB to really take advantage of all of these intakes but ohwells, maybe the smaller diameter = greater velocity

What's the diameter of the 4th gen TB, 55mm/2.1"?
I have a PFTB on my car and have been debating what to do for an intake setup. I currently have a cone filter with the velocity stack going into a stock 4th gen MAF, stock 4th gen accordion and then PFTB. I can't decide if I should build a 3" OD or 3.5" OD intake setup. Since the PFTB is 70mm/2.75", I would think a 3" setup would be sufficient, but if I'm going to go to the trouble, I'm wondering if I should just build a 3.5" setup. IIRC the 4th gen stock accordion did better on dynos than straight midpipes, so I wonder if going to a 3.5" setup would be enough to overcome that.

My vote goes for the 3.5", There was noticeable improvement over 3". I ran a 14.51@97.91 at 1700' with length tuned 3" piping and Z32 MAF, (less obstruction than stock A32 MAF but not quite BBMAF status) with ~13 AFRs, advanced timing and 7100rpm rev limit.
Then with a length tuned 3.5" intake & 3.5" MAF I ran a 14.79@95.98 at 4500'. This run was with rich AFRs (10-11), advanced timing and 7100 rev limit.
And this is all with PFTB.
This comparison wasn't done with a true 3" MAF and conditions weren't optimal so take it with a grain of salt. Though I will note that I have no intention of going back to a 3".

OH YEAH!
I forgot I have a Velo stack sitting in my garage, got rid of that piece of crap the first week I had the white nightmare.
That will be in the Dyno adventure also.

If so we can throw some DA corrections.

With the 3": 14.51@97.91
With the 3.5": 14.79@95.98
All I see is him being almost 0.3 second and almost 2 mph slower. Granted, he was running at a higher altitude and was running pig rich, but still, slower. And I might be mistaken, but don't people usually run lean after doing the BB MAF?

This 5.5gen would always beat me whenever we raced. His best time is 14.31@97.28. DA was around 2500' IIRC.
My best time that same night was a 15.02@91.99 Most of my mods were the same for that run in March as they are now except I had stock rev limit and stock 5th gen airbox.
Come November I have my 3" intake and 7100 rev limit, still couldn't beat his times. Best I could muster was 14.51@97.91 before my idler pulley failed.
Then we both race again in January at SIR. I have my 3.5" intake and 7100 rev limit. He has the same mods as before. I ran the 14.79@95.98 , and he couldn't beat that time. I think his best run was a 14.8x or 14.9, still waiting to hear back from him on that.
In conclusion, I prefer it because its faster than my previous setups.

For the 3" intake I will be using a 3" maf.
June 5th is coming fast, I need a test pipe....
Still not sure if I should put my cattman on for this, since only like 1% of 4th gens out there have a 3" exhaust, I'm thinking I will leave it off.

So June 5th has come and gone and there are still no dyno results. 
All of your tracks are within a couple hundred feet of sea level at most. That coupled with the cooler weather in the north east, its no wonder why you don't believe in DA correction.

i ran my PB in my 5.5 in high 80* weather so yea sorry i dont believe in the weather BS n making random calculations to say what a specific or round about time is, MD isnt really considered "NE" either hence why they didnt put us in the NE region on here also, we get as cold as NY and as hot as Arizona here, just as humid also because of where the state is located on the map.. all that sea level crap (which i do agree alters times)i dont really know or care about. never really know WTF is our tracks at... maybe im just being ignorant to the situation but unless we are talking NV/Colorado type alitutdes all that minor higher or lower crap is irrelivant to me, the car runs what it runs... nothing faster and the car isnt faster

The White Nightmare:
1996 5MT 200k+ Miles
-OBX Headers
-2.5" Test Pipe
-2.25" Crush Bent Catback going to some a/m muffler
Intakes Being Tested Are:
Stock intake
Bomz Short Ram Intake (What the red car dyno'd with).
2.5 ID intake
3" Intake+3" Maf
-The "Best" Intake will dyno another set of runs w/ a Stillen Popcharger, except the 3" setup, but if time permits I will do a 3rd run w/ the first 3 setups w/ a popcharger. I should have time to do this, a lot can be done in 1hr of dyno'ng
Same dynojet, wheels and MAF the red max used on it's 190/210 dyno.
Dynos will be done on the same day, 2 runs a piece.
I really want to dyno w/ my 3" catback, but it won't benefit most of the .org members so I will install it after the dyno runs.
I will goto the track with the "Best" intake and do a before/after 3" catback install too.

The hood will be open w/ two industrial sized fans on all runs, like they have been on all of my previous dynos. I know this will hinder some setups and help others, but I have to keep the dyno environment the same if I want to compare it to my 175/190 and 190/210 dynos for my own personal research (Trying to get 220 ft/lbs to the ground w/ a 3.0).
In the end, if one intake setup is TRULY better it should be clear enough based on the given environment (IMO)

POP chargers (Stillen and JWT) are 3", surprisingly. The bellmouth is 3" ID. This is what I made my most power with. 3" piping, fairly short and JWT POP.
Stock = Helmholtz in place, correct? This will cause some nice smoothing of the curve, remove it, and you get some choppiness post 5k.
How short is this SRI? Is it like filter coupled to the MAF which is then coupled to the TB? As mentioned before this will probably result in some choppiness.
What's the difference between the Bomz and the 2.5" ID?
Same with the 3", what is being used?

reason I bring these up is because no AFR conditioning will be done, as were these aforementioned posts. I've noticed that these imperfections (choppiness/humps/valley, etc.) can be corrected with some minor AFC work.

There were no spacers, stock throttle body, no tuning...... Tell me with a test pipe and spacers I won't be close to 220 wtq... and then past it if I ever do get the megasquirt deal off the ground w/ full standalone tuning..... But we're getting off topic...
And me.

-Stock meaning everything from the factory from TB to scoop over the radiator.
How short is this SRI? Is it like filter coupled to the MAF which is then coupled to the TB? As mentioned before this will probably result in some choppiness.
-No, there is some tubing, I will have pics and measurements and more details on the day of dynoing.
What's the difference between the Bomz and the 2.5" ID?
-The Bomz has a bigger ID, it's the same ID as the MAF and then I have to use a reducer coupler to couple it to the TB, unlike my friends smaller diameter piping which is the same as the TB but the MAF goes over the piping and uses duct tape for a coupler, but that car has a lot of KICK to it, especially for it being auto, definitely puts you in your seat on downshift, that's why I'm throwing it in the test.
Same with the 3", what is being used?
-PVC piping and duct tape, if I can't snag a Z-tube from work I'll just use that and the stock maf + filter.

Interesting... That's what I really think the results are going to be, I don't think one intake will make much more than 1-2hp peak, but area under the curve will tell a very different story....
I like when I went from Stock hemholtz to bomz sri, car felt alive all over the powerband, maybe it was the sound that fooled me, but we will see this sunday, did you send that TP? I need it for the runs so I can get accurate AFR.....

I'll see if I can send her lickity split so this can happen.
