I think scoops to help ram that fuel down into the engine would make a world of difference, like the kinds used on blow-though setups that direct boost directly down the venturies. The wind and weak vacuum is totally disturbing the secondaries.
hey neil. long time. funny how these things pop up in your feed after eight years. :) hope you are well and can find the time to get back to this project in time. quite the experiment...
Some models had a. Peace of metal that went between primary and secondary in top of Air horn. This stopped the secondarily from pulling fuel out of primary side . They run poor without it in place. Don’t ask me how I know. But I can actually see it happening in your video
it needs the induction pulses dampened totally different cam. its a grate set up 400cfm per cylinder . no matter what any one says. looks like the fire is coming back up past the intake valve , combustion hasn't finished part of induction pulse problem.
This is so unusual! So, it looks like the carbs are seeing such forceful pulses, that the secondaries start to flutter. The wind going over the tops of the carbs seems to aggravate that situation too. Where a normal manifold uses the plenum to dampen this event, these carbs are exposed to it directly. -- It seems like you'd need an X-pipe exhaust to force a more consistent venturi effect, and then somehow dampen the secondary flaps. Maybe a clutch master cylinder with the return spring pulled out can help this setup work. Basically the master cylinder would have to be set up to "bench bleed" itself all the time, and the vacuum activation is what's pushing it. -- I'm wondering if the ports under the primaries and secondaries are tapered in an odd way. If the air demand is really high and the port is directly under the secondary, then the signal will completely bypass the primary, and aggravate the pulsating effect. -- We can make this work. If an air box is installed over the carbs as high as the filter cleaner hole is round, it would work. We want the incoming air to form an eddy current with the fuel standoff. We can do this at a reasonable price with some diamond plate and some patience.
Great video for Quadraheads but, as you can see the engine runs great on 8 barrels. Although, when the 8 large barrels barely open the engine just floods and bogs down. Obviously, to much carb or carbs, stick with two Quadrajets and it should run great and not bog down. There is such a thing as too much carb or in this case to many carbs, nice to see it’ll work though if you don’t ever expect to use full throttle.....
Quadrajets use vibration to atomize gas and make a cloud of vapor. They need to have air cleaners to trap the atomized gas. They also need high volume fuel pumps or they boil over or run dry at 90mph full throttle. But get amazing gas mileage.
Why is she poppin when you hit the secondaries ? Intake valve not seating properly ? Or maybe a camshaft problem ?Or is the fuel pump not able to feed all those carbs at once ? How many electric fuel pumps are you running on it ? Wicked set up anyways and looks AWESOME !
Your set up is Cool as Hell. If this was a 1x4 or a 2x4 Quadrajet application I'd say the OEM sized fuel lines going to the Carbs are to small to get the volume you need at 7 to 8 psi even with a 0.152 Seat I.D. You should be running # 8 or 3/8 Pipe thru a large I.D. Regulator and right up to the Carbs to prevent starvation. But with a 4x4 Quadrajet set up maybe Your float levels say a max. of approximate 9/32" to 1/4" from the top of the bowl to prevent flooding on de-acceleration will get enough fuel to the motor without leaning or a horsepower loss. But I don't know if you are running a 400, 455, what power level or 1/4 time You are trying to achieve. I used to Port and Blueprint Quadrajets for all kinds of Racing and I know with the jetting right that single fuel bowl will empty ready fast over 450 HP if you don't have enough pressure and supply right at the needle and seat. My Brother and I built a 66' and 67' 442 Restomod Clones with single Quadrajets on Oldsmobile Small Blocks in the 80's. Yours is Really inspiring. Thanks for the videos.
Did you ever try this set up with the air cleaners on? My TA use to do this when I didn't run a air cleaner. I had more fuel on the windshield then went down the carb.
As a Qjet guy thats pretty wild! Not very practical but cool. I see the air valve isnt doing much and prettymuch just on the primaries but it does have that wow effect. I am impressed how well it runs tho. I made an adapter once to put a Qjet on a chrysler 2.2 in a ol bomber dakota cus the oem electronic carb was smoked, everyone joked calling it a funnel ram. It wouldnt pull the air valve open (when set right to avoid bog reasons) so it was 90% on primaries and it ran beautifull!, Then manual trans puked in 2 days. oh well fun experiment. Sweet job on ur quad quad!
Neat set up but do the heads move enough air? Granted, there are better 455 heads out now but olds are notorious weak on the exhaust side. What kind of mph does this thing run? She sounds mean but video does not look like the car is exactly flying down the road. Does it launch hard? I had to do a ton of work to my #6 heads on my 350 to get them to flow but she turned out to be a quite respectable little street motor. She can definitely light em up.
Needs just a Little More Tension on the Secondary "Air-Door" Torsion Springs. They'll Still Open If/When Needed, but it will eliminate the Flutter. With 8 Primaries feeding it, it likely doesn't "Need" the Secondaries At All until it hits 5 Grand or higher, and even then, They Should Gradually Open, Not Suddenly Snap half way open.
-50 mpg till you tighten the secondaries. You need a tiny hex to tighten and tiny flathead for the set screw. Or vice verse its been 20 years since I set one. That car should be going full sideways once you set it right. 2 would work better than 4.
What secondary springs did you use on the set of them? They looked a little reluctant at times to transition smoothly for you. Im just curious. I love the qjets, and that moment before the secondaries fully open lol
@@neilstanich7870 the ones that set tension against the cam for the secondary Plates? It's around the shaft, and wrapped around near the side of the horn. There are indeed springs wound around the shaft so that they arent just loose and floppy when it's time to draw thru them.
and theres not springs only one tiny spring that applies tension have been working on quadrates when you were probably a twinkle in your daddy eye my friend
😳 I've NEVER seen a reversion issue that bad before. I imagine with 4, 4-barrels, and the fact of the giant secondaries, the problem is a nightmare to deal with. Is the reversion a cam timing issue, or more to do with it being an I.R. intake system? I would LOVE to see this sorted out and running correctly. Good luck with it, and keep on keep in on with the project. 👍
Maybe that should work a whole lot better with an 8-71 under those quads..I'd imagine from the vapor spray. You can't put too much carb on a blower. Just thinking.
I was thinking that you could put a nitrous ONLY (don't think you would need to add fuel for some reason) plate system on it and spray an easy 250 shot. If the internals are forged and the ring gap allows it. Your blower idea sounds great but there might be a slight blind spot?
the vacuum control linkage to the secondarys is MONKEYED up. Notice how the secondarys are not controlled by the vacuum diaphragm unit. See the linkage bent wrong and its not moving either. The secondarys MUST be controlled by the vacuum system.
Because you have rite around 2400 cfm mounted on a engine that will not flow anywhere near that. So 1 carb at 650 cfm with a air filter on it will much smoother.
@@stanthrasher4815 the cylinders will only pull in what they can pull in. Doesn't matter if you have 700 or 7000 cfm. For this to work (and it can) it will require tuning. If it cannot work, it's not necessarily because there is too much flow capability, but because the of the position of the carbs not being optimal resulting in some cylinders running more lean than others.
@@stanthrasher4815 so 2400 isn't too much? There's a video on Uncle Tony's Garage about running dual carbs. It's his latest, or second latest posted video. Take a look at it.
Could you change the dashpot setup on the air doors to a more solid connection, like on a Holley 4160 carb? I think the slots in the linkage assembly is allowing the violent flapping of the air doors. Maybe even build an adjustable dashpot like the Holley? This is all speculation here, but I'm thinking that a solid connection would give you much more control over smoothing the action of the opening and closing. It has to be hard to get this to work right with the pulsation issues of an I.R. intake. I can't tell from my phone screen, do you still have the hangers and rods functioning on the air doors? I love playing with Quadrajet carbs. I once completely removed the secondary air doors, rods, and hangers from the carb on my stout 468 Olds engine. I couldn't get enough pump shot to overcome a lean bog if I stabbed it from a dead idle but MAN, if I laid right into it at anything above 2500 RPMs, the car would leave 100' of rubber from a roll, and pulled harder than it ever did. People wouldn't believe me that this would work, until I took them for a ride in the car. I tried the same thing on a milder 350 Olds, and it would bog badly unless the RPMs were up there a ways before you got into the secondaries. I wish I was able to get enough pump shot with this mod, the performance of the carb was incredible, but the low RPM bog at full throttle was annoying. I did drive the car for quite a while like this, and then ended up with a 1050 Dominator on it eventually.
I might like this more than you LOL. have you considered keeping the secondarys closed and set acc pumps to 50% ± and see if that is better or worse. if you thought 4 carbs was expensive wait till you price out how much for the tire sized air filter LOL. if you don't have a fire ex in the car get a friend to hit you over the head with a 2x4.
Wow I was wanting 3x4bbl on my Camaro thinking it was revolutionary guess I'm a bit behind. My question though is it efficient does it flow better than say a properly tuned Atomic EFI TBI by MSD? If so I'd like to see it pitted against Atomic EFI TBI 2x4bbl once MSD makes their TBI dual quad capable.
seems more like a thing to marvel at, and not really a performance machine to be taken seriously. No, simply putting bigger/more carbs on an engine doesn't make it faster.
Dog ass slow - that thing is way over carbureted ! The air speed in the secondaries is so slow that the wind blowing over the air horns pulls the gasoline right onto the windshield! Car would be faster with a toilet filled with gasoline.
The afr needle only 14 or 15 to 1 at wot she definitely lean at wot them secomdary definitely aint opening like they should definitely need to modify the secondary springs on the air valve

yo dawg, we heard you like quadrajets, so we gave you quadraquadtajets lol
the quadrate needs the air cleaners to be on so the wind does not blow the secondary fuel feed away.
good luck making an air filter manifold that fits that lmaoooo
@@Sg-jt6gy I mean if he build an intake and everything else, a custom air cleaner should be simple 😁
An air cleaner isn't the answer. Solving the reversion issue is.
I agree, those carbs need air cleaners to keep the feul delivery on point.
It would appear the windshield and top of vehicle are covered in fuel……
it's "around the corner per gallon"
A CAFE standards author is having a pulmonary edema right now.
Meh its CAFE. Put it in a massive heavy vehicle and this is instantly becomes technically more fuel efficient than a Kei truck by the standards.
I can see only one reason to put four of them on one motor, it's because its freaking awesome! It looks great, and what other reason would you need ;
I'm not going to lie this is pretty badass
Monday I had a 67 Chevrolet Impala 327 with a quadra jet I love that cordinarily I am 72 years old now
FYI, the gas should go in the intake manifold, not on the windshield.

I am amazed that the secondary air valves actually open for several seconds. Intake manifold vacuum is very low at open throttle. Low spring tension.
now I see what tyler was saying about loose air doors flapping and causing a bog
I knew someone else was thinking that too,.
yep you b right!!!
at what point did the engine bog in that video boys????
@@ednowaski1460 When the major reversion issue was happening. Watch again..
90% of the secondary fuel is going to the wind
you get an a+ for innovation
Must be fun watching gas gauge drop at wide-open throttle. LOL Tho it is a crazy awesome setup.
How this got in my feed I'll never know.
This is literally a "Hold My Beer Moment".
Never seen anyone drown a BBO in Quadrajets before😊
