&nbsp;&nbspLooking for some input. Either this is a useless mod and I wasting my time or it'll have a limited improvement over stock.<BR>
&nbsp;&nbsp The pics attached show an example of what I am planning. I would move the stock snorkel to front center and fill the hole left at the stock location. I would modify the stock snorkel or fab a new piece to marry the output on the TPI/MFI breather via a small piece of flexible tubing. The "new" snorkel would taper accordingly to the stock air cleaner assembly. The valve in the stock snorkel will be gone as well. <BR>
&nbsp;&nbsp I like this look opposed to an open element. I am going for a slighty modified look that, to the inexperienced eye, could appear stock while at the same time improve performance to a degree. I want people to go "Somethings different, but what?"

 

do a search, many others have done this, and its a good mod, and about the only one that is good and affective as far as a cai goes for our tbi cars

 

Looks good

I thought about putting on the TPI air intake like the one above, but have an open air element instead with the stock snorkel on the side. So that way you have a ton of air flow + cold air coming in from up front and the side.

Right now Im just waiting to find a nice, used TPI air intake so I can do it!

 

The moddfied TPI intake is the way to go to get that stock look with real cold air status.

 

useless

 

If you use the stock snorkel than it is useless an would pretty much act like it was in its stock location. If you cut the stock tube off and weld on a wider pipe (without the thermac) than it would be benificial to some extent.

 

too much work!! try this it looks good and isnt hard.
http://91rsramair.tripod.com/ i modified mine to work with what i had laying around.

 

This may sound totally crazy but i saw the pic for down the center and got the craziest idea:
What if you were to take a custom dual snorkle that is already made to fit the engine and a/c and all that and add the center duct to the air cleaner? I would imagine you would have more than enough cfm going in and it could make it look more "advanced" in terms of performance (i dunno if thats the right word im lookin for)... Like i said before, I'm half asleep, and thats when the crazy ideas pop out... Just an idea.........

That looks like it might work perdy well, but IMO it looks like crap! Ohh well...

Well it looks like I'm off to the boneyard to find a donor air cleaner assembly. hellraiser319, that tri snorkel idea sounds intriguing. Maybe I'll get extra lucky and come across a factory dual snorkel setup at a boneyard.

 

:werd:

 

check ebay, dude

 

why not just fab a dual snorkle

 

Because no matter how good a job you do it will still be a hack job. Holes that are cut and not punched tend to look like something chewed them out. Even if you could get them in chrome or whatever you favorite flavor is... pop rivets don't exactly scream good looks. And if it is welded, without the proper abrasives and taking your time to smooth out edges, it will look like something thrown together for an Ebay auction (please see post on "custom cold air intake").

Bottom line:
Shop around and I'm sure you can find a supplier that still carries the L69 breather. Even Year One still carries the air tubes.

On a side note... if you do get a L69 setup. And your car has the compressor on the pass side (as most L03 cars do) the pass side elbow will be very tight due to having to move the scoop on that side further out by about 3 inches. Also... bye bye water coolant reservoir on the pass side. Check out AZVOLFAN's setup for alternate reservoir location. Or you can just check out his setup just for the sake of looking at a damn nice L03 engine bay with a dual snorkel.

 

just get an open element. They look the best and preformance between it and the dual snorkel or similar setup is way too small to justify the hack job.

 

Someone used an air cleaner from a caprice to make a ram air with the tpi intake, and that looks like anything but a hack job.
Why not just an open element, then something to keep the engine bay temps down. A scoop somewhere be it on the hood, below the car, fender vents etc

 

There's no "ram air" with the tpi intake, just cold air. The snorkel is the restriction on the tbi setup, not the hose or the plastic mouth. It's a big waste of time for fab a tpi system. I agree about the open element and "scoop" idea. I have an open element with the K&N x-stream top with a cowl hood. Best induction anywhere for our cars.

 

I don't like the open element look. I am not going for maximum performance with this car just some mild mods. Trust me, it won't look like a hack job or it won't go on the car. I am going to start on this as soon as I find a donor piece. Should be done in a few weeks as time permits. I will post pics again when I am done. Thanks for the comments from all.

 

Check out some of swerve driver's postings, he built a beautiful ram air setup.

I did mine like this: Bought the ram air ducts for tpi off of ebay. Used the tpi aircleaner to a short piece of pvc pipe and connected to a '91 tbi caddy "hat". Though I "felt" a difference, I can't say I have any times to prove it. But I was also running uncoated headers, and even with the cowl hood, the engine bay was hot, and cold air was limited.

I really like the design of the caddy tbi "hat", as it seems like it flows nice and smooth, definetely better than a modded stock aircleaner would be for ram air. The only down side is there are hood clearence issues, and the bottom of the caddy aircleaner needs to be sanded down to get it to line up with the tpi aircleaner.

Major downside to the system is 1) rain is a problem, and 2) the tpi cleaner itself is very restrictive.

 

ditto swervedriver has a real good one.

 

Well, I installed my setup on my '91 l03, and it fits like a charm. I was worried about hood clearance issues, but it ends up sitting about the same hieght as the 3" open element. I should have pics up next week.

 

Don't you have a cowl hood? Doesn't a "cold air" intake pretty much defeat the purpose of a cowl hood?

 

check this out... there are pics of swerve-drivers setup... very nice

BTW, everybody says i want ram air, or cold air, or open element or something else. Why not try and combine them all? Im still trying to work on the ram air/cowl hood idea but its coming along. And, yes, i realize it would require a custom air cleaner assembly but i believe i can make it work. Basically id take what swerve drivers got, run the ram air tubes down to the grill and create an opening that comes off the back of the air cleaner assembly and faces the opening in the cowl. Contour the assembly so that it follows the same lines and curves as the cowl hood and fender and get some kick*** design airbrushed on top of it.
Thats my idea. I think it would make the engine compartment a lot more visually interesting and add a moderate amount of performence. Yes, i realize the gains would not be tremendous or even great. But there would be some gains, esp at higher speeds, and, as stated above, i believe would make the compartment more interesting.

 

Yes and no.

I really needed the cowl hood because of the rpm airgap on the '90, but had already started on the ram air idea. I still have the stock hood on the '91 though. The cowl will be swapped on there soon though-need to get the hood painted yet. When I run at the track, I will run with the ram air w/ no filters, as well as running with no aircleaner setup at all, and hopefully come to a conclusion on whether or not ram air is worth it on our cars.

I like the way ram air can be setup on thirdgen camaros, given a z-28 grill. I think the limiting factor is actually the tpi portion of the aircleaner assembly.

works very well in a cool summer night. very cool effect!

Is that just blowing on an open element?

 

eehm. yes.
I think that's a good compromise between cold air and open element.

the main area where the tbi sucks in the air, is from the front and the sides so I think on higher speeds (30+) there will come some cold air into that area.

25th is right


He said useless, ill add on pointless to that.

If people would stop wasting time with mods that cost alot of time and money for no benefit they might actually have fast cars.

oh well I dont mind, I like being underestimated (thirdgens are slow )

 

Actually, without experimentation, this board may not even exist as we would all have swapped over to carbs, you know that as well as anybody. These mods may have no benefit for your setup pablo, but they may for somebody else. Your setup requires lots of air, a close to stock L03 does not. So given an L03 only needs X cfm, and perhaps these cold air ideas flow the same X cfm, why not induct cold dense air as opposed to hot.

Also, cold air/ram air can be had for cheap. My set up cost me maybe $60. Will it work on the 383? It seemed to before, though I never had track based comparisons.

 

hey s!mon nice setup, did a good job on it. as for the stop and go performance, might want to watch the temp guage a lil. engines perform better when cooler (duh) and i only see one issue that could be getting in the way with cooling like with the stop and go performance. if it is running a lil warmer than it should, try a cooler thermostat and maybe set up the cooling fan(s) to come on earlier so it gives more of the cooling effect. also, you might want to try adding some holes in the back of the pipes for the intake behind the grille so more air can get to the radiator and help cool it off. or maybe fashion a duct that funnels more air from underneath. whatever you may do, i suggest doing it now if its running warmer before summer all out attacks our hemisphere (then again germany may be a lil cooler than midwest US i dunno never been...) anyway i just thought i would help you out before somethin goes wrong. otherwise nice job again and watch out for them cops
