CAI+Vortex Generator

[VSCristian]

I own a 1997 VSII Executive V6 Auto, 247,000kms (owned since 211)

I've added a RACE Flow CAI (hi flow pod filter in custom airbox) and a Vortec Cyclone vortex generator between the filter and the MAF

being a student I looked at economy but performance is always welcome...

am really happy with the setup; the vortex generator sucks more air in, while the CAI gives it a much bigger mouth to suck through... the whole thing cost $380

too poor to get a dyno... full time uni student BUT...

consistently getting around 9.5-10.5L/100km in w.syd AND when it comes to performance....

the car feels 100kg or so ' lighter'....

ive noticed that the transmission is a bit more hesitant to change gears with soft throttle applications... at full throttle its acceleration is frightening.. especially in 'power'

i suspect on reasonable grounds (literature) that the setup added 15-20kw and 20-25nms

any thoughts?

Hate to sound critical but....
vortec thing did nothing so remove it and put it in the bin



secondly the power button is not a nos button, it dosnt boost the cars power.
10ltrs per hundred isnt particulary great either.

But have a read through the site and you will learn a few things.

[VSCristian]

ur right, 10L/100km is not spectacular, BUT.... it's an improvement from my previous figure of around 11-11.5L/100km..... (driving has not changed.. still from home to uni etc, still drive like a pensioner because the engine's thirst is proportionate to its revs)

I have been reading through the site....

I was under the impression that the power button delays gear change allowing the engine to rev higher...

the car does handle differently.... especially when going up hills...

[VrWagz1]

thats exactly what the power button does, but the engine will rev high if you give it a bootful with or without power button. No actual power gain is acheived by pressing it, it just plays with the shift points of the autobox.

like i said in the other thread, you joined less than a month ago. you are not credible. no one will believe that a restriction in the intake will give better performance and economy. no one credible has ever said they work, and i believe there is a very good reason for that.

if i read correctly, you installed a cai AND a vortex... well it's the cai that gave you more power; try taking the vortex out, you'll notice no difference.

by the way

the whole thing cost $380

you just failed real hard. you paid $380 for a piece of plastic intake, and another piece of plastic to restrict your air flow. my cai cost me $30 and probably works better than yours. you said you can't afford a dyno? you could have afforded 2 if you didn't pay $380 for an overpriced piece of placebo.

[GetToDaChopa]

Now i feel ripped of, my CAI cost me about $60 (or close to that).

And as said above you are probably restricting the airflow if you have that thing in place.

[delcowizzid]

and being that you have it in front of the MAF its going to be thinking funny things then its going t5o straighten the flow out sfter its gone through both screens of the maf and not even be doing what its advertised to do FAIL on 3 accounts one for fitting it one for fitting in front of the MAF and one for being suckered in LOL

[Ozzie]

The vortex cyclone only circulates the flow, by the time the air goes through your MAF into your throttle body it would have done nothing but restrict the flow.

Have you seen air circulate through a corrigated tunnel? not possible.

Plus the MAF filter is a restriction on its own.

I installed the CAI first, and the Vortex thing about three weeks later... I did notice a difference when I installd the CAI, especially above 3000rpm

when I installed the vortex thing I again noticed a difference in Jenna's (my commodore) handling, including at lower revs, and also when it comes to economy, I noticed an improvement when I installed the CAI, and another when I instaled the vortex thing


being at 310kms on half a tank where before it used to be 230-260kms for the exact same route, at the exact same time, on the exact same fuel, in very similar weather leads me to suspect an imrovement..... and from what I've read on this site, and from official holden specs 9.5-10L/100kms around town in moderate traffic is a decent figure for the VS commodore.

[stocky]

the only one youre trying to convince is yourself. noone here is going to believe you. i would have expected more intelligence from a uni student. how on earth is this piece of crap going to affect your handling?

[Jesterarts]

how on earth is this piece of crap going to affect your handling?

MAGIC!

[SweetWagon]

the engine's thirst is proportionate to its revs)

Not quite, more to do with throttle application.

Eg. You add a 800kg trailer on the back, you will still be revving the same on the highway yet need more throttle applied to maintain a consistent speed, which in turn is going to return worse economy.

Also similarly if you are engine braking down a hill, the motor may be revving say around 3000rpm yet not consuming virtually any fuel as the throttle is closed.

[Philthy]

I wanna add as well that flat out is flat out whether you have the power button on or off. So if you noticed a difference at WOT with the "power" button on then it's all in your head, much like the 15-20kw gain.
You may have gotten 1-2kw from the cai, but probably cancelled that out by placing a big chunk of metal in your intake pipe

[levymetal]

put your money where your mouth is cristian, buy one and send it to me. i will honesty try it out. it's in my best interest to tell the truth, because i'm about to drive 600kms a week @ 18L/100km. if it magically did work and increased my economy then why would i lie about it. and i'll try it once if it's free. i still don't believe it though, it's just a placebo. you ever wondered why all 'questionable' devices NEVER work for skeptics? because they don't subconsciously react to whatever they're using - ie, you're probably driving slower and you don't even realise it because it's your subconscious that's telling you to do it.

[VSCristian]

I didnt mean to sound arrogant nor cheeky,

I cant affurd to mail you one and even if I did it would be silly of me to send one to a complete stranger, no offence....

one of my mates has one in his AUII ute but it didnt work as his airhose has too many bends

ecotec is almost straight....

just hypothetically speaking... what would a vortex in the air-hose do to the engine's induction?

I emailed both holden and FIT (the blokes i got my CAI from) and they both said it could give a boost...

just out of curiosity, where can I get my car dynotested, and how much would it set me back?

[S2_VR_]

VORTEX = Shit...

use Vortex fuel. then maybe you'll see a bit of difference...

[VSCristian]

that 95 or 98 stuff??? holden said that 98RON fuel wont do the ecotec any good because the compression ratio is only 9.4

95RON they said I might see an improvement in fuel economy but not by much

[muggo05]

mate dont just use 98ron for power, because it is waaaaayyyyy better for your engine than that 91ron shit. 98 makes your engine run cleaner and burns more efficiently, and is a lot cleaner than 91 because it is more refined.

it gives more power as a result of being a cleaner and more efficient mixture.

[_R_J_K_]

98 makes your engine run cleaner and burns more efficiently, and is a lot cleaner than 91 because it is more refined.

it gives more power as a result of being a cleaner and more efficient mixture.

No, it's cleaner because there's so much more detergent in it (much like injector cleaner), also, how does an engine run cleaner? I doubt it would give you more power. You can get much more economy from 98 if your car is tuned to suit. Cars in Australia are tuned to run 91 because that is what we are mainly sold.

[muggo05]

it runs cleaner because it doesnt have to burn away all the dirty deposits that are removed and refined in 98ron. therefore 98 burns more efficiently which means better economy and slightly more power.

[Sgt Santa Cruz]

i dont need to run a vortex or cai i have a k&n panel filter in my car doesnt even use petrol anymore it runs on the vapours of the recharge kit.. i cant even turn my car off theres to much flow...

[Cobez]

I reckon if you throw one of those electric superchargers on, your car will be a weapon

I can't believe you actually paid CASH for one of those. I wouldn't pay MONOPOLY money for one.

Massive Ebay fail. But, the people on Ebay still make money from suckering people like you out of cash.

[VSCristian]

just refuelled, after using 95RON caltex vortex, and I got 8.82L/100km and thats around town with limited highway.... and that highway was crowded!


that's bloody decent.. (i was driving like a cabbie)

using 95RON seems worth it.... and those mods paid off......

8.82L/100!!! thats 11.33km/L

that's bloody good for a VS around town!

skeptical or not... im bloody pleased with it!

[Cobez]

Dude, people can get those figures in a VS V6 without the "mods" you have done.

Your not fooling anyone. Leave it alone dude, they are crap and you got ripped off.

[Kingo]

I saw those things on ebay and laughed. Just for future reference mate, if they list the EXACT same product for 100 different cars, same picture, same description and fill the description with 10 pages of crap then for sure its a load of wank. its just like the resistors people try and sell on ebay

if all you were interested in was saving some cash, just stick your car on gas. you can't beat it for economy ($/km) that is.
