That was a joke too......

Guess if it doesn't have "lol, haha or " you can't tell the difference huh..

I've been using a v-stack for about 5-6 years now; when I had a stock h22 engine in the car, with some cams and other little bolt ons, I did back to back passes on the track with and without a v-stack.

No stack: 13.2@xxmph

with stack: 12.3@xxmph

Sorry I forgot my trap speeds but I remember being blown away by the e.t. and thinking "damn, this stupid thing actually works!" haha. Hope that is helpful...

its kind of subjective, as i have a new engine as well. BUT, i got to line up along side my sons car twice.

he's running 10.1:1 power to weight in CRX
I'm at 10.94:1 power to weight in an EF

In theory, if we both have similar tires and transmissions he should walk me all the way down. about 1/2 track, he'd had a car length on me, and stayed exactly there. Twice.

We both feel that the V-stack helped me on the top end. Just a "smidge". I mean you are ramming 80-85mph air down that tube, there has to be some benefit. and even if it amounted to 5-6hp in this case, it would certainly allow very similar cars to notice a slight difference. 1/2 a psi on a 200whp engine should amount to 5-7 horsepower.

Can I prove anything? nope. I suppose if a guy had a vacuum/boost gauge mounted in the tube somewhere it might show a tangible result. hard to spot a 1/2 a psi.

I will say this. His car should walk me on the top, it didn't. Plus a CRX, compared to an EF is substantially more efficient aredynamically. So he has that in his favor to.

I'm confident my car will go slower without it. I'm running it this way from now on. Once I get the chassis more dialed in, I'll switch back to the "under the hood" intake piping and see if it shows up. I'm betting it does. 2mph is my guess at this early stage of the game.

Fun experiment, AND, the best part is, it's relatively cheap power as things in the Honda world go. And truth be known, I think the V-stack looks badass coming out the headlight hole. It says, "I only care about one thing". I think it makes a cool statement too.

Panty hose Bob...

A whole sec.? Thats crazy! did you re-tune or just throw it on??? ive heard of a tenth, maybe 3 but a whole sec. DAMN!!! lol

Im doing the same exact thing, half headlight, half velocity stack. I was thinking about going with one of those flared velocity stacks though. Also just saved that pic as my background lol. Integras doin work!

my wife said I can't wear those any more... wait... what?

Wouldnt panty hose have that "screen door" effect like you were describing? On a windy day, a screen door is hard to open since there is wind resistance on it. I would think the panty hose would be worse. Since the holes arent that big and would even have more of a resistance and disruption on the flow and the volume.
I think the Panty hose idea is the worse covering you can do to an intake hole.

^^^agrees with this guy^^^

on my true street car i gained 3lbs of boost and 68wheel on the dyno just by putting a velocity stack on the turbo under the hood i was amazed never have moved it out front

JO TECH

We have on the black widow and we never have a issue also the owner use the car everyday

no retune... Just slapped it on. Mind you the original intake had a filter on it and it was a short ram. The length of the intake makes a big difference on how effective it is.

The original intake in this comparison was a short ram while my obviously my velocity stack stuck out of my headlight... so yea, it was a huge difference...

would love to see some more pics of the placements of the VS on your cars!!

Boosted_B_Series

Can you guys please post pics of your integra head lights cut in half to accept a intake on the high beam side?

I've been staring at my itr head lights for a good 1.5years wanting to do this, but have been scared to ruin it.

I've been wanting to use the turn signal hole for a intake.

I have heard of na v8 guys seeing positive plenum pressure doing this. I've seen 4mph.

Extra head light?

vectorsolid

What's really missing from the equation is the density altitude. For all we know was 9500 feet the first day and 1500 feet on the day with the Velocity stack.

Only real way to test on the track is to do it the same day within a few minutes of each other.

It's even plausible that the V-stack hurt performance and you're just seeing favorable air.

HPgonewild

or sensors?

It was at Sacramento raceway. I forget the year. It was a back to back comparison. I got smoked by my buddy's LS Turbo EG; I put the vstack on after that pass and we went at it again, I smoked him...

I never said the comparison was between two separate days because that wouldn't be a comparison at all...

do you feel it made any difference off at an angle versus straight?

NABeastRR

good question, didnt even relize that.

i got a question the point of the v stack is getting that mass amount of air with speed. What about the password jdm intake that in the shape of the headlight for civics. Has anybody ever tried this to see the differences at the track compared to the v stack?

nonvtecallmotor

I run a screen.


9 tenths from a scoop? Ha yeah right.....

N.Y.C.E.

I guess I have buzzard luck, the first time I used a long ram with filter coming out the headlight I sucked in a rock. The rock/pebble beat up the head and piston, I suggest some type of screen.

vectorsolid

rather than running 3" all the way back... anybody ever try to run 4" V-stack and then put an 18" long piece of tubing in there that tapers from 4" to 3" over the course of that 18". so it mounts to the v-stack at 4", and then tapers to 3" and then WHAMMO, right into the Throttle body.

I bought a 4" v-stack, I'm gonna try it.

Picture makes it easier to understand.
