I'm thinking about buying this.... anyone know anything about this???

I have a 305 TBI

RyanJB

I'd just save some money and run an open element, honestly. It wont make that much of a difference.

white1991rs

I would avoid Spectre products. Get an open element like RyanJB said above or you could rig something up like I did.



I plan on building these aluminum air boxes like Hawks Thirdgen offers to increase the airflow even more.

RyanJB

Not to mention, an open element is in going to run you like $30 at auto zone or whatever

Similar to white1991rs the bottom photo is probably one of my favorite cold air intakes. Summit and Jegs Racing on line have a large selection of 14x3in round open air assembilies to look at. The local autoparts stores near me are carring the Spectre and K&N compleat assembilys. Heres mine with the cowl hood. =

ajStyles2015

Ohh I kinda like hat last one you posted Ron on the green camaro what is that air intake called so I can look it up. And as far as the Spectre goes I would never use a Spectre filter I just wanted the pipes then I was gonna get a k&n filter

Ron U.S.M.C.

.
The actual intake in the photo below is of a 1991 or 1992 TPI Camaro intake system.You can find them in the wrecking yards or EBay and I’m sure that places online that specialize in Camaro parts should have it. The TBI unit on our cars will need the Bonnet that goes over the throttle body and the snorkel that connects the two parts together like in the photo above. Should be able to find them online.

Side note = I was given the Spectre 14x3in element as a gift and I added the Summit brand filter top about 6 years ago. I have closely visually inspected the K&N filters and the Spectre and Summit filters side by side and other than mine coming in a really cool Red color could not tell the difference between the three as far as texture and thickness of material. They are made of the same cotton gauze material and filter in the same way. I even use the K&N cleaner and oil on mine. May be just looking is not a flow test but it’s the only tool I have. If I had to do it all over again I would chose the K&N because it’s made in the U.S.A. and that's really the only reason. Hay,maybe I will get this K&N system for my B-Day =

$150 is a good deal, I haven't even been able to find a carb hat for less than $100.

robotic_junky

In case anyone is wondering, the hat part is from a 4.5 or 4.9 Cadillac V8 from the mid 80s to the mid 90s. Some were TBI and others were MPFI.

Like this one.

white1991rs

Ron do you know who makes that last set up you posted thats similar to mine and if they are still available?

Ron U.S.M.C.

Post #8 and #10 explain what cars they came from. I would think you might be able to find the parts on Ebay or if your lucky a wrecking yard.Im not sure if they are being sold buy anyone as a package. Sorry

Heres part of it.

I subbed this thread hoping someone would have a place to get the carb/TBI hat and flex tube. I could not find anything like it. I already have the TPI airbox, I have been looking at a single plenum CAI hat by spectre. There are aluminum tubes and adapters that will work. But that last setup looks slick you posted Ron.

Edit; foot in my mouth, found the hat. Still curious as to the flex tube though. Is that from a TPI?

robotic_junky

The flex tube looks like it's from a carb set up on a regular 3rd gen. Look at Post #3 and look on the right hand side of the motor.

I think you're right. but looking at the prices,$50 for the hat on fleabay and good luck finding a caddy in a yard in good ole WV. I may just go with the spectre hat and aluminum tube. Plus, the bend would have nothing to go around in my V belt pulley system.

Ron U.S.M.C.

Yes this or a close variation of it is what I would run if I did not have the cowl hood. This unit to me looks like one of if not the best cold air (ambient temperature) intakes I have ever seen with in the vehicle.

Ron U.S.M.C.

Would you post a link to the hat/bonnet please .

Joe Tag

Found it on evilbay. Just queried 4.9 caddy air box.

Try variations like "4.9 cadilac intake, plenum, air cleaner". You'll find sellers that should have the part. Just message them and ask about it.

Hey Ron. I have a question about your TBI intake setup with that CAI from the TPI car. I have the hat from the caddy and everything else but I can't see to get the hat on my TB. Did you do anything to make it fit to the TB?

CharlesIROC-Z28

Ron U.S.M.C.

Sorry but that photo is not of my car.

Only the red open element on the red Camaro is mine.

CharlesIROC-Z28

Ahhh. I see. Do you have any clue why it is? I think I need a longer screw to hold the hat in.

Ron U.S.M.C.

The stud that holds the hat on will most likely need to change.

They make kits that you can find or order at Autozone and other automotive stores just for that problem.

Just a word of caution, when working over the TBI with small parts place a rag over the opening so you don't drop anything down into the unit.

Here are some = http://www.autozone.com/intake-syste...mString=search

robotic_junky

Did you take the collar off, that is on top of the throttle body?



Also the air cleaner stud will raise up a little bit unscrewing it.

CharlesIROC-Z28

I had the collar on. Am I suppose to keep it off? Without it it will work with the stud. And what hose do I use to connect the hat to the intake?

Ron U.S.M.C.

You can remove the stock spacer/collar only if the unit does not hit the linkage. If it hits the linkage you must use it and address the stud problem.

As mentioned by robotic_junky, if you unscrew the stock stud a little it will be taller.

CharlesIROC-Z28

Oh. Ok. What linkage are you talking about? And I have already tried unscrewing the stud a little more. I'll be doing the work again on Tuesday when I have time.

Ron U.S.M.C.

The hose you need is the same one that is connected on a air intake of a 1991 or 1992 TPI Camaro intake system . Find it either on ebay or a wrecking yard.

Linkage I am talking about is the mechanism on the side of the TBI that moves the throttle plates when you step on the gas pedal or use you hand while in the bay to rev the engine.

If anything is touching it ,it can jam the throttle.

CharlesIROC-Z28

Oh. Ok. Thanks Ron! Much appreciated.

Lol when I was a kid a cold air intake was a 7" snorkel hood scoop.

Ron U.S.M.C.

For a long time now the term "Cold Air Intake" is used to describe just about any attempt to pull ambient air from outside the bay into a TBI/CARB/Etc.

I think that term was made up by some one trying to sell a product . "Cold Air" sounds pretty good.

The reason I posted this style intake to begin with is because IMO it comes as close to a actual "Cold Air" intake as you can get for a street legal Third Gen.

CharlesIROC-Z28

True. I've always liked the Intake setup the tpi camaros have of this generation. You can't get any closer to a CAI stock than this setup.

Ron U.S.M.C.

I would run it if I did not have the cowl hood.

I may not be pulling in air totally from outside of the bay but I really can't see not using it.

Open a cowl hood and its only natural to see the open air element.

Besides mines as close to a sealed cowl element as you can get without a air box around it.

nicktalaga

I say mine up yesterday. Just a start

CharlesIROC-Z28

White1991rs what air cleaner is that off of that you have. I have everything else but air cleaner I just swapped my TBI to carb performance parts and I still have all of my parts I followed that USMC told me to grab. Just that air cleaner on top is what I want to look for now. Lmao.

robotic_junky

85-92 Camaro stock TPI air duct is the top pic. The air cleaner itself, you'll have to use a carb/TBI style air cleaner and add another opening on it for the TPI air duct.

Hope, that's what you're asking.

Ron U.S.M.C.

If your interested in this then all the information concerning it is in this thread.
Here's the intake boot. You should be able to find one on eBay "used" that will be a lot cheaper = http://www.ebay.com/itm/NOS-90-91-92...5VXR2C&vxp=mtr


Heres the air intake box = http://www.ebay.com/itm/85-92-305-35...9VRrWm&vxp=mtr


Heres the Hat or Bonnit. It can be called a few different names. Just click on the picture. = http://www.ebay.com/itm/OEM-1995-Cadillac-Deville-4-9L-V8-L26-Air-Intake-Hose-Resonator-Tophat-top-hat-/231713648522?hash=item35f335af8a

I really like this and would like to build it too, but not to sure if the California smog police will let me pass on visual inspection.

Ron U.S.M.C.

They will not.
Every thing before the cat that is related to SMOG in any way must be stock.


There are a few exceptions that are CA legal like some headers and I believe some Intake manifolds but they must have a special stamp saying so.
Even then it close.


I keep all of the stock pieces in the garage and install them every two years just to pass.

You're lucky Ron getting checked every two years. They get me every year. And my numbers are good each time.

Has anyone attempted to use the Spectre air cleaner 14" low profile air housing on a mid 80s firebird here? I put on an Edelbrock 3701 intake manifold that raised the OEM carb up 1.-3/8 higher so I need something to drop the height down to clear the hood on a 86 Pontiac s/e 305 . pics would be nice here. I'm trying to see if it would work with the OEM HEI distributor as well.

Interesting fab work.

That hat/bonnet on top of your fuel system is restricting your air flow and starving the engine for air at high RPM.

Tombowman89

too bad it’s doing exactly as i built it and making power at the exact range that the cam manufacturers spec was at, I won’t be telling the specs of my build and am not saying I have a super motor by any means. But it actually does work for the rpm range. Btw this motor doesn’t even have crazy lobe separation, duration or lift. If I wanted higher rpm I would’ve done those things, but this is just a street motor. I wouldn’t be showing a real race set up when most people who chime are just blowing smoke and can’t back it up with real test data.

Aaron R.

Because getting (only) 390hp out of an SBC is a closely guarded secret?

Tombowman89

Your right? Not really but I’ll let you have this one since “sometimes you can’t teach an Old Dog new tricks”.
The numbers that matter are the columns CHP. CLB concerning Flywheel HP and TQ. Again I’m not concerned with my numbers because I already made more without even pushing and I compare that against guys like BPE, GM and whoever so sftu. There actually is more power potential with the motor but the ECU being used only allows fuel and timing adjustments at 3 different pedal positions in a Edelbrock ProFlo4 anyways. But I’m sure with your vast experience in reading dyno data would you even know where to find this at anyways.
