With a Holley this is what I used. I've researched this before and have found that 75% say go with a divided spacer for a dual plane intake and 25% say it makes no difference. When do I use an open spacer? This got us wondering if there is a better compromise to be had with carb spacers, instead of replacing the entire intake? A few "experts" have said that there is a scavenging affect when one half of the engine starts to take the fuel from the other half since it's a "dual plane" system. For maximum power on dedicated racing applications, you want the tallest spacer possible as long as the engine accepts the added volume -- often this will be a 2" tall spacer. Joined: Jan/09/2011. Content intended for mature audiences. I'm no expert, but I'd match the spacer to the manifold.
We do not recommend the use of open spacers on dual-plane intakes. The idea is the throttle plates are closed most of the time so your blasting your fuel mix right into a wall when you use a four hole adapter. 0 5 200, 000 miles driven in Four Eyes, and over 350, 000 in Fox Body cars. I prefer the standard spacer designs, but in some applications you might see gains from that anti reversion lower spacer design. These are mostly closed but have a gap since they are meant for an open plenum intake.
Anytime the air/fuel charge has to turn sharply coming off the carb, it increases the chance of separating the fuel from the air. After replacing the open spacer with the 1-inch, 4-hole design, the peak torque once again remained at 370 lb-ft, but it occurred back at 4, 300 rpm. Along with the extra plenum volume, the intake runner volume is also increased, potentially allowing the engine to breathe more efficiently and ultimately make more power. Whether a spacer actually will benefit any particular combination is kind of a crapshoot. Spacers are said to improve air/fuel vaporization through and out of the carburetor. If I take a 600cfm Edelbrock Performer carb, put it on an open 2" spacer, with multiple gaskets at the bottom to keep the heat from going into the carb, and put in on a dual plane Performer 289 intake, will the "open" of the spacer affect performance on the "dual plane" of the intake? The best spacer I found was a newer design tapered spacer -- these have cnc machined transitions to the plenum. Sustainability goes the other way: from aluminum, plastic, and wood.
Re: Effect of open spacer on dual plane manifold. As Wilson Manifolds' Keith Wilson puts it, "An intake is like a camshaft—they're both infinitely adjustable. It's like an entirely different car. Get them from half inch to three inch and have a mix of open and closed plenums. Dual Plane Intake Manifolds. Search by Make/Engine. Spacers are used for various purposes.
Posted: Mar/26/2013 at 2:32pm. The dual-plane design promised ample torque production with plenty of peak power and delivered just that. But there's still the issue of total system volume versus engine airflow requirements, so in that sense spacers could still prove to be of benefit on EFI setups, although less so than in a traditional carbureted application. A spacer with 1" height will pick up power and improve distribution throughout the powerband without any compromises. In that the dual plenums are linked under the spacer, they appear to be designed to add plenum volume to a single plane intakes plenum, and smooth the air flow transition from carb to plenum, so that will have a similar effect to this[/b]. I was told by a guy to run a different carb spacer. There's a nearly endless amount of potential intake manifold, camshaft, carburetor, cylinder head, exhaust headers, engine bore and stroke relationships, and spacer configurations and heights, so no one really knows "for sure" whether any given spacer will help or hurt a specific overall package. Intake Flange: Thickness: - 1 INCH. Ill also add that if you have the room under the hood, adding a second phenolic 4-hole 1/2" tall carb insulator or swapping to a 1" or even a 2"phenolic 4-hole spacer may further improve the carb cooling and may help the fuel atomization slightly, but the correct spacer must be matched to the style of intake manifold. Transmission & Drivetrain. Like NDA says, it depends on the engine, signal at carb and manifold entry.
The object is to increase the plenum volume and effectively reduce the abrupt angle change the airflow leaving the carburetor venturies must make to enter the intake runners, because reducing the abrupt angle change tends to reduce fuel, droplets from falling out of the intake runner air flow and puddling in the plenum floor area. 9 [typically for Tunnel Ram Intakes]. If your carb ever gets really hot while driving, downshifting and reving it up to increase airflow helps. There are a few crucial questions that will help to narrow down which spacer you should be looking at: - What is this spacer going under (Carburetor? Increasing plenum volume in the intake with a spacer tends to make the engine run as if the carburetor your using is slightly larger than it will without the spacer, generally reducing the upper rpm powers curve and slightly reducing the low rpm torque, but each application will have slightly different trade offs, sometimes the gains far out weight the losses. HVH Super SuckerHVH Super Sucker. A carburetor spacer increases the intake plenum volume by creating a taller neck on the manifold. Height: Many variables are at play when determining how tall of a spacer to use for a specific application, such as camshaft specs, manifold size, cylinder head specs, hood height, etc.
This design ensures the mixture entering the plenum has the least amount of air/fuel separation possible, which results in improved horsepower, torque, acceleration, and fuel mileage. They are a MODIFIED open plenum design, like this. The extra distance helps the fuel/air mixture to remain more consistent. I noticed an increase in torque myself.
I've seen carbs get so hot, the accelerator pump shot vaporizes before it leaves the discharge nozzles. What a spacer does is add both distance from the carbs base to the plenum floor and extra volume to the area of the intake manifolds plenum(s) (in the case of a dual plane split plenum) adding distance and volume tends to allow a smoother more gradual change in direction to the air flow volume, this tends to allow higher engine air flow to effectively enter the individual intake runner passages thus potentially raising engine rpm. The primary way a carburetor cools itself is by the intake air flowing through it. These are available in different types, but the best heat blocker is the 4-hole variant. How would this affect carburetor tuning? If there is still a heat problem, a heat insulator or spacer can be the solution. Watch out on 327's with factory Holley 4bbls. 2, bought a plenum devider kit for it and dropped to 14. When it comes to 4500 (Dominator) carburetors and throttle bodies, there's a bit more to it. We make our spacers for both 4150 and 4500 (Dominator) patterns. I installed a 4 hole phenolic spacer and proper gaskets to match.
1976 Sportabout X, 304, auto, air. They seem to have an anti reversion design to limit reverse flow from the plenum which can be useful. What type of question would you like to submit? Some engine combinations benefit most from a tall spacer while others will perform better with a short spacer. 0L bump stick from COMP Cams, the XE274HR grind that offered.
And that, of course, is exactly what the Lord does. Here are a few suggestions.
