i was interested in fitting a cold air induction system into my VL exec. Is it worth doing? i have made no changers to the engine yet but i hope to start by fitting this. I want to make it a home made job, any ideas would be great! cheers

This site has a search function people. Cold air in an N/A won't make much difference, and its been covered on here milions of times.

Ok the stock time for an N/A auto Vl 0-100 is 11.7. My car only has a CA intake, advanced timing and AFM mesh removed and a few restrictive hoses replaced in the intake. I went 0-100 repeatedly between 8 and 8.8 seconds, on optimax. "Cold air intake on N/A wont make much difference." Not by itself but it's cheap and combined with other $0 mods you can get a 3 second gain 0-100. Wake up.

That sounds a little bit far fetched mate... We're talkin a big jump there from not alot of work at all. And in an N/A thats a bloody big acheivement.

well my n/a runs 0-100 in 9 seconds flat with only a chip, cold air, and pod. im not sure if it could pull an eight but then again i dont care! its just a thrasher car

probably most of that gain was from the advanced timing what did u get it advanced to?

Admiteddly it usually runs around the high 8s towards 9.0 mark, but thats when ambient temp is higher, I dont lie and have had my car run well under 9 for 0-100. When i first tested it, it was high 11s all the time. $0 mods are aplenty in the RB30. Mind you optimax is expensive. My next car should run the 1/4 in a similar time I didnt get my timing advanced to anything, i got out a timing light and advanced it myself to 25degrees BTDC.

Curious, how do you get these times? Just a mate and a stop watch? or something more elaborate?

i put a POD on my N/A VL, it hasn't made much of a difference, but just kindof made it more responsive. prob not worth the money, but i picked this one up cheap!

I put a nice fat cold air intake on my car. other than that, she's stock as. Now that the intake is on, you can hear the intake sucking with a deep ruching sound from up front in the middle of the rev range. Nice sound methinks.

caution though if you drill a hole into your guard and run an intake pipe down there, my mate had one, went through a small puddle and seized his engine.. it just sucked up all the water...

if you do it right, and still have a filter on, then there should be no problems with puddles unless your going across a flooded road 4 feet* deep. if you angle the pipe downwards then any water that will go up there, will just drop back down - the filter will filter out any fine bits (like it normally does when its raining !), so you should have no problem. * Actual measurements have not been made, and should be used as a rough, and imprecise guide. Some figures may also be grossly exagerated for effect.

he had his angled down.. all i'm saying is caution if doing it...

Speed and Force will do it: The engine could suck water up the pipe if the throttle was fully open. Driving along a road that's just had heavy rain will also drive the water up the pipe. The combination of the two can have dire consequences. We've all hit areas of water on the road that kicks the steering wheel to the side. It doesn't have to be "4' deep" to do the damage. That's why the best cold air induction is the factory one (HSV) on late VS V8 C'dores and others. It's up nice and high away from harm. Some original photos have not been recovered yet.

bah, there is a nice article on autospeed.com with steps and measurements and tips etc if you are still interested after this load of crap. :evil:

I recently put a cold air intake on my car (using 100mm PVC pipe, from under the air filter to front of bumper bar). The only difference I have noticed is the car runs half to a whole bar cooler on the temp gauge. I also brought a cap for the PVC pipe to put over the end if I am going on a dirt road or it looks like raining heavy. Its also piss easy to do and costs about $10 for pipes.

So speed and force won't do it in Brisbane? Are things that slow and sleepy up there? Some original photos have not been recovered yet.
