open element...or dual snorkle??
open element...or dual snorkle??
i have a homemade dual snorkle with cowl induction top going to my cowl induction on my 84 TA...there is no ducting going to the headlights for cold air...so whats better? dual snorkle with cowl....or open element?

Nothing screams "ghetto" like dryer ducting on for snorkles. If you're going to go dual snorkle, do it the right way.
My open element is cheap, works way better than the factory snorkel, gives a better intake noise than any snorkle will, and IMO looks better than cheap ducts cluttering your engine bay.
Of course, somebody is going to bring up the possibity that you can gain an extra tenth with a dual snorkle, but I think a proper cowl and an open element will perform as well as a dual snorkel.
Just my opinion.

but i dont have the "ghetto" dryer ducting...i just have the dual snorkle housing with the stock cowl induction lid on it. so im basicly bringing in hot air from 2 snorkles...then the blast of fresh air when the cowl opens up

My suggestion would be to go one way or the other--but not both.
Can't you have your cowl induction working all the time?
If not, then do the dual snorkle setup properly with ducting going to the front of the engine bay to get cool air.
It is worth a quarter second in the ET, so it is worth while to do it RIGHT

The 2" filter will flow all the air that engine needs and more. Forget the 3" business. GM will sell you the proper flexible ducting. You will just have to find the snorkles. An LG4 drivers snorkle works great once you wrap the end with tape to form a tight fit to slip the ducting over.

No there will not be any restriction issues with that setup Bull has. Once the air hits the element you have lost your free flow anyhow. There is other hose you can get but will not look as good as the stock snorkel tubes. That is a clean and done right setup he has there.

Fattie,
That is the EXACT factory L69 305 HO dual snorkle setup. Don't worry, it works perfectly, like 1987fbd said.
It also knocks 1/4 second off your ET--which is about 20 hp.
Starting to like the idea?
I thought so

20 horse?!?!
Sorry buddy, there's no way marginally colder air is going to give you an extra 20 horse, on a 165 horse 305.
The stock setup was not that restrictive, and if you're missing 20 horse when using an open element, you're doing something wrong.
Just out of curiosity, how do you think the air is getting into the snorkles from when the hood is closed? Hmmm...
The L69 is better than the stock LG4 snorkle, but it was still designed with noise resrictions and emission restrictions in mind.

Not to burst anyone's bubble, but I think the factory snorkel setup L69 is GARBAGE! Thats not how I have mine done. How is air supposed to get to the engine through those the tiny slit in the hood above the headlights??? I removed the inner headlights and mounted ducted so that air gets rammed directly into the air cleaner. Is my picture not working again?? Damn I must be cursed with computers.
well iv got a firebird so i cant take out my high beam. when i race i can move my turn signal for better flow, thats bout it.

I've always assumed that .25 seconds was equivalent to around 20 hp when you are running about 16 seconds in the quarter mile.
Have I miscalculated?

And how do YOU account for a quarter second coming off the 1/4 mile on a 305 3rd gen from the use of just this dual snorkle setup?
Does that sound like "garbage," as you say? Got anything better?
I didn't think so

Next time put your brain in gear before engaging your mouth.

what are the part numbers?
what are the part numbers for the ducting and the plastic scoop things? GMpartsdirect.com doesnt have them listed on the page, i keep getting "please contact cutomer service"

My last opinion I sware...LOL
Fattie, go dual snorkel L69. You will be happier.
Open element without cowl or ram air means hot air induction
Dual with snorkel tubes with cowl or ram = :lala:
Dual withOUT cowl or ram is not totally fresh air but not hot air either. basically end result would be =
It's your car dude the beauty in that is do whatever the hell you want to. But this is a great place to get diverse opinions.
Have fun and good luck on your choice.

I just think it's funny everyone on here argues about the air cleaner, open element this, dual snorkel that...
Mine likes running without an air cleaner at all best... I gained three tenths at the track by removing the air cleaner completely.

I don't run it like that on the street... only at the track.
I'm just saying that it sure shines a different light on the cold air vs hot air... then again... the open element probably made the air hotter than no aircleaner.

Ok first of all, why is the factory design so ingenious?? Are you telling me that two tiny snorkels will filter the air better and flow more air than a large square hole mounted in the hi-beam location with a SCREEN on it?? Thats rediculous.
And second, think about it, the car got .25 faster because it had two giant holes instead of one tiny hole. HOWEVER, in this argument we are talking open element versus dual snorkel, not dual snorkel versus single TBI style snorkel. Perhaps you should put your brain in gear and READ THE POLL TITLE before going off on someone :lala: :lala:

20 HP from an aircleaner change is WAY extreme. Supreme Member

CLEARLY I was responding to your "GARBAGE" reply and not the poll question.
Thus it is YOU who have set off a "pissing match," as you describe it, by telling us our setups are "garbage."
Furthermore, I explained the ingeniusness of the factory design but you apparently didn't read that far.
An engine only needs as much air as it needs. Beyond that it is of no use. Obviously the dual snorkle is supplying it, due to the .25 decrease in ET. It is a ram air effect, same as you are using with your single big hole, which supplies an abundance of cool air.
Finally, how many additional hp does it require to knock a quarter second off the ET?
You have a secret formula? Want to share it?
Perhaps your single big hole knocks even more time off the ET. Have you timed it out for us with comparitive 1/4 mile runs? Love to see it

Outside of a rear gear change or slicks, I know of no way to decrease ET except through additional HP. If the dual snorkle is not developing more hp from the engine, then please explain why the ET has gone down .25 seconds. Isn't about 20 hp required to knock a quarter second off the ET?
Anyway, have a good day. My apologies for snarling

Exactly what he said! 20HP very realistic. Oh ya and when you get that secret formula up can I see a copy of it also

Mmm, I don't want to perpetuate the argument, because I agree with the guy that says it shouldn't be that big of a debate, but generally MPH in the top end is a better judge of horsepower.
With different launches, track temp, shifting abilities, etc, the ET can change, but the MPH will generally be similar.
For example when you've got a third gen running 14.4's with a 305, @ 92 MPH, and after a 350 swap you are rewarded with a 14.3 timeslip, but at 104 MPH, you know that you've reached the current tire/suspension/gearing limit.
You get CarCraft, right Sitting Bull? The 540 horse Nova, with the stock Powerglide, and one legger, is a good example.
I think it ran like 15.8 @ 97 MPH.
Very unbalanced ET versus MPH. A 97 MPH run should be into the 13's with good traction.
Looking at the ET, you'd never have been able to predict that the engine was putting out 540 horse....

When a car is doing 16s in the quarter mile, it might only take 15 hp to knock that .25 seconds off the ET, I'm not absolutely positive.
But when you are in the 14s or 13s it is the acknowledged rule of them that every tenth of a second off the ET takes 10 more HP.
Still, outside of this thread I have never heard anyone opine that the dual snorkle is not responsible for it.

Ok ok, enough of the bench racing. I'm taking my girlfriends camaro to the track again this Friday and I'll bring my dual snorkel setup, the open element 3inch, and a single snorkel and test em all. Her car is pretty consistent because I've got a set of E.T. streets and it has a 3,000 stall converter.
