Velocity stack position

[Quest]

lol just reminds me of my j's racing intake haha, comes with velocity stack i guess.
cept that its onli two peices, that one shown there and anotherone to block off air coming from other places.
after i installed it i noticed it was a bit more responsive?(installed it like 2 weeks later) haha mayb i was just trippin haha

The J's kit is what prompted me in this direction....specially the air scoop. I am trying to weigh up if scooped air is better than ram air, performance wise

if i had a K&N SRI, would using the drycharger on the filter be a better idea than using a sock/mesh over the velostack??

Hadn't thought of that in an SRI setup.....I am planning to enclose my SRI, like J's...seen all possible mods there are....but I have found something new.

As I am in the architectural field, there is a new product being made. Its basically CNC high density polystyrene and polyethelane coating...Being used for ceiling cornices, slabs mouldings etc. Seen a sample yesteday, and it feels like rock even though it's polystyrene.

Makes the term 'icebox' more literal. Anyone thought of this or tried anything similiar. Will speak to the rep for a quote after I model this in 3D.....she only needs the 3d model for cnc cutting

I guess you have never tired running one. They stay remarkably CLEAN I have been running one for three years with nothing but a big hole, even with the open part outside the bumper and never a mouse, a few bugs, NO DIRT but anyway that is why you still run an air filter to prevent anything (even on a stock airbox) from entering the intake system.

And you lost me how would "Stuff" going in there "Fcuk the compression"???

umm im running at VS at the moment but with a pod over the top of it.. and havent tried running it naked yet.

yes you're probably right about the piping staying CLEAN, but how do you know that the dust bugs and shit like that isnt going through your intake manifold and into your motor? i was under the impression that if shit goes through the intake system dust etc etc that it would mess up the compression of the motor and would do more harm than good? (im talking about without a filter/pod)

are you running with or without a pod? im confused from the above..

Seems to be that the concensus is worrying about dirt,flies and debris trap in the bumper let me tell you it is not like that I have been driven with the velocity stack for well for a year now and it is clean in there so there is nothing to worry about. If you are paranoid about it just put like a screen surrounding the opening but you will limits the amount of airflow to the stack though it is not like a cold air induction where the intake sit in the bumper now that has to be worry because you will trap more dirt and debris and chance of hydrolock.

Velocity stack, inside fender, AIR FILTER, piping to the TB. I can tell whats come in every time I wash the car I stick my hand inside to wash the inside of the fender and no trash. Then check inside the box where the filter is and nothing. I do get small fly sized bugs in 5,00km between washings of the filter (if i drive a lot at night) but they get trapped by the filter doing it's job. I run a filter on the street always but have run without a filter element while at the strip.

The only way it could effect compression is by wearing out the rings more quickly. It theoretically could happen but it would take quite a few hundred thousand KMs to increase the wear unless you drive on dirt roads all the time

ahh yeah you're running the same as mine then.. take it off at the strip.. and for everyday driving its covered by a pod.. but mines a SRI so yeah..

cool i understand now..

i wouldnt run it without a pod for day to day dirving anyways..

Putting the velocity stack behind the bumper defeats its purpose. For a velocity stack to work as designed, you need to place it in front of the bumper where air can hit the lip of the velocity stack without blocking by the bumper/fog light hole/divider in front of a/c fins.

Thanks aaronng...exactly what I hoped to hear

Catch more air
Don't defeat the purpose of the velocity stack
Smooth pipe up to hole in fender

This is a 90 degree pvc plain pan collar(100mm dia)....I think it might be a bit deep, may have to opt for the 90 degree pvc rainwater downpipe shoe (80mm dia)

Had a local performance header and exhaust installed on Monday.. Cord registered 164.5kw ATFW.. .......The only mod is the Diy Sri ....wit the performance exhaust and header,, this dropped to 148.7kw ATFW....will post dyno Monday

[johnprocter]

wtf so you lost power by installing headers and exhaust?

was it the same dyno on the same SAE correction?

two different dynos can easily vary 20kw...

Same dyno....Installer is befudled.....said I must bring the car back so that he can redevelop his header and exhaust for my car spefically, as it's unique. Is ther any specific header or system he should be investigating 4 my Cord?? This will all be done to his own cost.....also, this was an inland dyno...Local Skunk2 guy is also very interested in supporting me..........Waiting for Mr A to respond

small N/a engines will loose power from a badly designed exhaust system...

so let me get this straight, you had 164kw atw from a K24A3? wat did you have do to it?

cause thats extremely high figures for a K24...

Typical for "custom" headers and exhaust. The system you have might not be an equal length header, so you will lose power compared to stock.

Something similar to what happened to the guy in this article: http://autospeed.com/cms/A_110591/article.html
