Heads up on factory CAI

[Vlad01]

Been doing some testing on my vp with the following

newish "barn find" V6 engine
T5
Pacemakers
66mm throttle
Polished manifold elbow
KN panel
Factory CAI
Green foam tune.
Weight reduction (mild)

Top speed 170kmh max. Major problem here!

Removed CAI scoop and just ran air from the open inside the engine bay.

Retested on a shorter road, and topped 190Kmh+ (4th gear) before running out of road.

Yep! conclusion. Factory OTR CAI suck balls.

In case you are wondering how I tested on a road? a helper was down the run with walky talky keeping me informed. Also my helper would wave down anyone coming just in case. Also this done on roads where you lucky to see a car every 2 hours.

Cheers.

Well that's going to piss everyone off when they max out at 170km/h on the road in their VPs............

Hahahahaha

[Not_An_Abba_Fan]

Which is why drag cars don't run intake tubing at all.....or even air filters.

[Vlad01]

haha yeah. but I was shocked to find that something that is suppose to increase air flow was worse than stock? Never the less I am doing this...

I have cut the induction bit that goes into the box and re-melted the plastic back together in the opposite direction, so it points down. Then I will run a 100mm insulated aluminum duct from that to one
of the corners just behind the bumper.

[wortus]

170km/h yep major problem when you hit something at that sort of speed dude!

[wraith]

I just got the bottom of my airbox, cut it and managed an easy 230 km/h on a public road compare to the 200 I was getting before.






Not serious...

[con7502003]

wot a load of bullshit drag racers not using air filters ffs

[wikky]

wot a load of bullshit drag racers not using air filters ffs

Ummm.....the majority don't.

[TVR-190]

i think my vp would disintegrate at anything over 160

[Super_Low 91]

i think my vp would disintegrate at anything over 160

hahaha i like that comment lol,,

[VK SL 3800]

wot a load of bullshit drag racers not using air filters ffs

Having worked on a top fuel drag car i can assure you that they have no air filters or even an oil filter, they just run a scoop straight into the supercharger with the butterflys at the top. And they run oil very similar to gear oil...................

hahaha i like that comment lol,,

hahah yeah same

[VNSS90]

Cai made my vn v6 goe heaps harder i removed some rubber that was under the bonnet preventing air from getting to it left all the other commies for dead in third lol

[sawychri06]

maybe CAI on reasonably stock engine at full throttle is killing the fuel air mix, unlike the stock airbox or restricted airbox which is limiting the amount of air unlike the CAI. not sure if im even close but thought i would take a guess

to me more air not enough fuel means less power

also mate save ur testing for a track or strip not a public road. its not other cars that u need to worry about its the trees and poles that will f**k u up and the last thing anybody wanst to hear is about another person to add to this yrs death toll

WTF does the American CIA have to do with this.

[sawychri06]

sorry mate lol just got home from work not all with it CAI lol

[wraith]

Haha least you took the joke. In fact this entire thread is a joke I am suprised it hasn't been closed yet.

[sawychri06]

hahah mate cant get shitty with u 4 making a joke on my behalf

[Vlad01]

Yeah I removed that from the very start. so that wasn't the problem.
Did some maths. area of air intake at the front of the scoop 45cm2, area of elbow inlet 60cm2

So the actual initial intake is much smaller then the connecting elbow. also this awkward shape and cornering of the scoop effectively reducing the intake area.
Air is a fluid (scientifically speaking) and it wont take corners well and exponentially gets worse and velocity increases.

Good to see mate some people get a bit uptight over nothin these days.
We had a saying in the Army, NAFA. Not another f**kin acronym.

[kitted vp]

well for a starter a cai setup is not specifically for the purpose of more air it is designed to feed the engine cold air unlike the hot air that the stock intake feeds on in a searing engine bay! colder air = better combustion which = better throttle response and better fuel economy ect! hence the use of intercoolers on turbos and supercharged cars! i know a couple of people that actually threw intercoolers on non forced induction cars and they gained a bit more power (not much) but a gain is still a gain!!! and yeah 170km is shocking my vp t5 v6 wagon pulls 130km out of 3rd at 4000rpm backed off at that as im a father and i value my life not to mention i couldnt handle the stress of being responsible for the death of someone elses family members!!! and ive got an ss inductions big mouth cai a 2&1/2 inch exhaust and thats it! currently building a v8 eating twin turbo 3.8 that my mate whos a retired race car mechanic is helping me with (should be niiice)!!! but i have seen those factory cai setups and they are very sad compared to the ss inductions setup! but the whole idea behind them is cold air not more! better than those factory setups is to purchase a big subwoofer port that will mount in the base of your airbox, remove your whole airbox and cut a hole in the body for the port to drop down through into the wheel arch, seal up the factory intake hole and hey presto custom cai CHEAP!!!

[wraith]

No offence but that's the biggest load of shit I have ever heard. Chucking intercoolers on an N/A car won't do shit. If it did wouldn't you think V8 supercars etc would of done it. The only time you will have hot air with my set-up (cut bottom of the air box) is when your sitting at lights when you don't need the benefit any way. The way I have always thought about it is the less complicated the air intake piping is the better for the power. Couldn't get much better then a huge hole to scoop the air into the box.

[kitted vp]

wraithwell for a start v8 supercars setups are highly controlled to keep the competition as even as possible so its more of a drivers race not to mention it would be about the same power gain as a cai and 10 times the weight!!! and bullshit what do you know about intercoolers? what do they do? they cool the air to much colder temps than any cai or a huge hole in the airbox ever would and they are most commonly used in turbo applications because the hot exhaust gases are driving the turbos turbine and the turbos housings get so hot that you end up forcing hot air in! and as i said before colder air = better combustion which = more power ect! i should have some idea as im building a twin turbo 3.8 that will be getting a monster dry ice cooler! and the only reason they even considered this mod was because they had mates that were upgrading thier stock intercoolers and thought they would give it a go as the intercoolers were right in front of them for next to nothing! and one of them has a brother in -law that owns an auto shop and the car went on the dyno before and after with a gain of about 8-10 kw which is about the same as i get from my ss inductions setup and he did it for about 80 bucks cheaper than my setup but had he gone out and done it new it would have cost him about 200 more than mine and still he would have all the extra weight! so unless you can do it from start to finish for under 100 bucks its just not pheasable! and you probably still run that bullshit corregated stock air hose that restricts the flow of air dramatically while your sucking even more hot air in though your bigger hole! i dare you to find a temp gauge that can read your engine bay temp at the opening to your airbox and have the gauge inside your car and read it while your cruisin the hwy and see just how much the outside air rushing past cools your engine bay down! youll be very suprised!!! that is why even stock setups have the snorkel right behind the headlight think about it

[wraith]

Learn to use spaces man far out. You sound like one of these tossers who heard from a mates mate how he did something to his car and made it fly. Yeah I am using the factory corrugated pipes. I bet if I went and spent 300 bucks on a full stainless pipe with silicon hoses I would get exactly..... 0.1% gain. You ever touched the top of your manifold? Hot isn't it. Ever heard the term radiant heat. I bet the warm manifold will out do any benefits of your "cold air intercooler assisted" CAI
