Greetings All.

Has anyone run thier car without the snorkel...BUT with the stock airbox??

Cheers,

Yeh,i did for a while,made a decent note,but the motor,getting nothing but hot air,made it run lean,so i switched back to the S#$%house snorkel

Greetings All.

You mean decent note as in...intake...or zorst?? (Can it change the zorst note??)

Cheers,

It will just change the induction note, better off to replace the snorkel with some CAI tubing and run it down behind the front bumper. That works a treat.

Will any tubing do?? (LOL...the reason i asked is that i couldent be f***ed putting it all back together...):bowrofl:

Well I used 100mm flexible heat ducting avaliable from bunnings wearhouses. Its about 10 bucks for 10m.

Very good stuff, looks good, flexible and doesn't retain heat like other tubing can.

Wouldn't it have run rich? Hotter air = less air mass = leaner.

Thanks blake...did you find it made a difference?? (Fuel?? Performance?? Anything??)

Redav I think the MAS sensor senses the change in air temp and adjusts fuel accordinly, i don't know why it would run lean though.

Definatly a difference in power and fuel economy, it felt so much better on the freeway, you could feel the torque alot more than before.

Best to have a K&N panel filter though.

Thanks Blake...ive got an auto...so ANYTHING will help...
By the way...how'd you attach it? Was it loose or something??

Cheers,
--Tonba

i just enlarged the hole slightly, still made sure it was smaller than 100m in diamater so i just pushed it through (its pretty flexible) and secured it with duct tape. Very easy and thats all you need to do.

Greetings All.

So, the pipe that goes down towards the front scoop/wheel...that pipe is loose? or you did something with it so it was attached...(i might even cable tie mine...hmmmm)

Cheers,

It was a sug fit behind the fog light cover (i removed it) and used cable ties to secure it.

CAI - one of my favs....
Use good quality tube, which is smooth inside, to prevent bad airflows.
100 mm might be too big to run between battery and fan casing. 80 mm will do ok.
I have aviation grade aircon pipe, some 80 bux a meter.
Don't allow the tube to have sharp bends - everything has to be as smooth as poss.
Block the remaining hole in the airbox with plastic and paint the lot, to make it look nice.
I actually clued and riveted a 120 (?) deg PVC elbow on mine and then just pushed the tube in to it, tight fit.
At the bottom I used a bracket bolted to the radiator reservoir bottle bracket, so it sits nicely and tight. Had to cut off the plastic dust shield a bit too.
I also have bell mouth at the front end of the pipe, to collect more air.
I have no fog light stuff, so I just took off that piece of the lower mask and devised a squirrel catcher metal net there. To keep squirrels and other predators away.
Good luck.

Oh - hot air has less oxygen in it per cubic meter, hence less combustible mixture. That's why the loss of power.

i reckon this would be a very good way to go with a K&N panel because theres not much work in it. probably be nearly as good as relocating pod and maf into bumper(very tight), but without all the work, water splash problem, or risk of getting crunched in a prang. i would go for 90 mm piping because its tight fit for 100mm going down between radiator and trans. i would also get a bit of nylon flyscreen and cover end of piping with it to keep dirt out. use cable tie to keep it on. the radiator coolant bottle bolts are a good place to secure it all onto.

i had the same tubing that blake did, and i was able to just shove the tubing into the hole already in the airbox, and it sat there snug. and it jams into the fog light pretty well too.

u do have to bypass a narrow spot thou, that i was a bit siapointed with, but im sure it did get some cold air alright. but if u havent got a K&N panel, definately get one

could some one post some pics as im having a bit of a hard time picturing some things in my head :nuts: .....

Greetings All.

Ok, peoples...1st day of having no snorkel. The car didnt rev nearly as hard...here is what i found. (Rough estimates...dont quote me on it.)


4th Gear/80Kmh (No mods) - 2000RPM
4th Gear/80Kmh (TJ Sport Muffler) - 1800/1900RPM
4th Gear/80Kmh (TJ Sport Muffler + No Snorkel) - 1700/1800RPM
Im going to enjoy building a CAI...Some pics would be VERY helpful!!

Onlyone I have, but. No nice pic of the bellmouth and front mask tho.

DAMN!! How'd you guys get everything so clean man??

Woulden't that tube disrupt flow killer??

Cheers,

i took the filter out one night last week and left the hood open (only with the safety on) so that "cold" air will make its way in.

the engine was performing sluggish and the sound was awful (V12). don't know why - maybe the MAF air flow?

I have found that in most cases anything done in front of the maf sensor results in a loss of power and rough engine characteristics.
Unless your gonna go proper cai kit and have it tuned like a unichip, you may as well stick to the snorkel and panel filter, just cut off the rubber section on the bonnet in front of the snorkel so the cold air gets in, simple.

why cut it off? you can unscrew it easily :)

the biggest obstacle though is the bonnet's locking thingy - it stands in snorkle's way when the bonnet is closed

i took that plastic covereing off such a long time ago and never thought twice about putting it back on.
I see nothing wrong with the snorkel for the moment,
im gonna be keeping mine due to the fact im too lazy to go changing round stuff these days,
yes im getting old :bowrofl:

Might not be the smoothes flow, but it's still directing cold air into the airbox. The flow will not affect the MAF because the panel filter will smooth it out.

How do you guys find this driving around in teh city - I'm thinking that having the snorkle down so low the engine will eat other peoples fumes and pick up loads of hot air and other crud.

Following the V8s I know they get heaps hot eating each others fumes when they have to bunch up under safety car.

yeh like on the freeway and s**t, cos if you run it down to the left fog light chances are it will line up nicely with some other cars exhaust, so yeh, how do you guys find it in everyday traffic?

Clean? Toothbrush of course! :D

Whadday mean with disrupting the airflow?
The whole idea with that CAI is to improve the flow, cos the std snorkel is not the best idea under the moon. Air-feed on the snorkel is based on the surrounding air pressure to push it along the narrow gap in the bonnet where as properly devised CAI with bell mouth actually forces the air in to the system. Nope, not a turbo application, but better than std design. And it does work and make a diff.
Mine works well, no disruptions at all, on the contrary. The tube I use is virtually smoth inside - it's not cheap stuff.

Sucking dirty air? Hmmm, does ~30 cm height change make a difference? Interesting question. Never thought of it being relevant. Not the fact that it's closer to road, hence might be sucking bit hotter air due to hot asphalt etc.
Perhaps somebody would like to conduct a scientific research on these matters and advise us all accordingly? Anyone?

I was looking into the SS Induction System and I was asking the Rep if it was actually worth it. He asked me what car it was for. I told him about my TH Magna and he said not to worry about it. The Magna snorkel is actually quite well engineered and an SS induction system will be of little or no benefit. He suggested to "extend" the snorkel to just behind the grill with a bit of stainless steel. Remove the plastic trim where the bonnet latch is and have one fabricated. In effect the snorkel will now "scoop" up cool air from in front of the radiator. Also the idea of using metal piping for a CAI is a catch 22. Metal does take longer to heat up promising cooler air for longer, however it WILL heat up and once it does it takes longer to cool. That's why plastic is preferred. Quicker to heat up but quicker to cool down. What ever floats your boat i suppose. :doubt:

SS induction systems for most cars eg commodore, are basically same as the design of the stock magna setup, (wide funnel going over radiator) the difference is it has an aluminium scoop in front of it under grill. they also supply a dragon hiflo panel filter.
I did first of all make up aluminium scoop in front of grill on the magna, it should have been working in theory but i could hardly feel a difference, wheras cai ducting down to inside bumper bar is a noticable gain and easy to setup if your keeping airbox.
a lot of commodores instead of getting the dragon setup, just put a pvc pipe straight through bottom of airbox and through the inner skirt in the engine bay and they say it works well :cool:

i do beleive i will be printing this whole thread out and beginning a little CAI project soon :cool:
