For example, the large hi-po air cleaners used on musclecar-era Chevrolets (like this L88 Corvette baseplate/element combination) are ideally suited for single carburetor applications. Manufacturers such K&N offer similar air cleaner configurations. Shape and size dictate the ability of the air filter element to flow the maximum amount of air into the engine.

In the case of a K&N element, you can use the diameter of the air filter to help determine sufficient area for the airflow required. K&N’s testing has shown that for most two and four barrel carburetors, airflow is greater when the diameter of the air filter is large in comparison to the height. For example, a 10-inch diameter by two inch tall element will generally flow better than an element five inches in diameter and four inches tall. ionic pro turbo ionic air purifier reviewIf space permits, K&N advises using a filter element with a height 1/5 to 1/4 that of the air filter’s diameter.benefits air purifier ionizer Back in the day, if you wandered over to the NHRA Pro Stock Truck pits between rounds you’d find something pretty interesting. air purifier electromagnetic field

Nine times out of ten, those race trucks used some form of filter element in their air intake system. They were there to filter out dirt and dust, of course. But more critically, those filters were being used to straighten and diffuse the air before it entered the carburetors. The air cleaner elements weren’t hurting performance—they were improving it. And an air cleaner can do the same thing for your high performance street or race car. Obviously, you need to select an air cleaner with a filter element large enough to do the job. For example, the 14-inch by three-inch element in 1960s-era Chevy muscle car air cleaners is ideally sized for many single carburetor applications. It’s so good, in fact, that aftermarket manufacturers offer clones of the Chevy filter. Companies like K&N offer many different types of air filter elements and air cleaner assemblies to fit varied carburetor sizes and shapes. Some (especially circle track models) are even offset to clear distributors and other engine hardware.

What’s more, the properly-sized air cleaner assembly with a high-flow element can actually increase the amount of airflow into the carburetor. Shape and size dictate the ability of the air filter element to deliver maximum airflow to the engine. When it comes to the shape, K&N’s flow bench data has shown that for typical two and four barrel carburetors (and fuel injection throttle bodies), airflow is greater when the diameter of the filter element is larger in comparison to the height. For example, a 10-inch diameter by two-inch tall element will generally flow better than an element five inches in diameter and four inches tall. If space permits, K&N advises using a filter element with a height 1/5 to 1/4 of the air filter’s diameter. Element diameter in relation to carburetor or throttle body throat is also important. The element should be at least three times larger than the throat. The one exception to K&N’s rule is when a filter element is clamped to a long runner, like with cold air intakes for EFI engines.

The straighter the airflow shot into the intake tube, the less restriction there will be. In this case, an element that has a height two to four times greater than the diameter will work best. Once you have determined the proper shape, you can determine element size. Two factors dictate the filter size: the engine’s cubic inch displacement and RPM at maximum horsepower. Knowing those figures, use this formula to determine the minimum effective filtering area an engine requires, where A equals filtering area: A = (C.I.D. x RPM) / 25,500 With the effective filtering area established, we can determine the required element height (including the rubber sealing edges), where H equals height and D the estimated maximum element diameter that will fit in the engine bay. The .75 figure is to account for the element’s rubber sealing edges: H = A / (D x 3.14)  + .75 Let’s apply these formulas to a carbureted 454 cubic inch big block V8 with a 6,700 rpm horsepower peak.

Applying the formula for filter area, we came up with the following: 119.3 = (454 x 6700) / 25,500 To determine element height, let’s assume the element will be 14 inches in diameter. The correct height is as follows: 2.71 = 119.3 / (14 x 3.14) If you refer to the Summit Racing catalog, you’ll note that K&N part number KNN-E-3027R is 14 inches in diameter and 3 inches tall, so it would be suitable for our 454. We should point out this formula usually produces an odd element height. If that’s the case, simply select a taller element.

Complete System Includes Everything You Need Supports Return And Returnless Fuel Pump Systems Made In The USA 1-Year Limited Manufacturer's Warranty Your classic vehicle is likely to be equipped with a carburetor. With millions on the road, carburetors "can" work great. If you drive your carbureted vehicle, you're familiar with the issues that come with it. Drivability is not great in cold weather or when driving in high elevations. They can cough, sputter, and even stall which, can be dangerous. And, they are prone to carboning up which leads to even more problems. Often, a re-tune can solve your problem for a little while but good luck finding someone who "knows" how to tune your carburetor right!  And, the tune can even change over time requiring another re-tune. The all-new MSD Atomic EFI master kit was designed to solve all of the problems. In a matter of hours, you can have modern fuel injection technology and solve your carburetor drivability and reliability issues once and for all.

The system works with all 4150 style 4-barrel square bore intake manifolds. You'll be able to retain your throttle linkage and kick down linkage (if automatic equipped), air cleaner system, and your mechanical or electronic distributor.  Installation takes approximately 1-day with basic hand tools. Once installed, the initial tuning setup takes only 5 minutes...just answer six simple questions and you'll be up and running! It's compatible with today's ethanol fuel blends. You can even electronically control your timing curve (see TIMING CONTROL REQUIREMENTS below)/ MSD's Atomic EFI system includes everything you need including a cast aluminum 1000 cfm EFI throttle body with exclusive annular booster rings for perfect fuel atomization, 1.75" throttle inlets with roller bearings for smooth pedal transition, integrated leak proof fuel rails, an integrated ECU with sensors (self calibrating TPS, 2-Bar MAP, IAT, WB02, & Fuel Pressure), fuel based rev limiter, high quality pre-terminated wiring harness with only 8 connections

C.A.R.B. 50-STATE LEGAL:  The Atomic Throttle Body EFI system, PN 2900, has been granted Executive Order number D-722 from the California Air Resources Board. This E.O. number permits the installation of the Atomic TBI system on 1987 and older GM passenger cars and trucks with a V8 gasoline powered engine originally equipped with a carburetor. Other vehicles and manufacturers are pending approval. For emission compliant installation, all of the original control components must be retained including the catalytic converter, EST distributor, AIR pump, EGR, etc. An addendum outlining specific installation steps and settings for a CARB compliant installation are included separately with this kit. COMPATIBILITY:Not compatible with engines over 800 cubic inches, distributors that produce hall-effect 5V signal, engines producing over 525HP at the crank, DRY nitrous oxide systems, forced induction systems producing more than 14 psi. 

Injectors sizes are fixed and cannot be changed. TIMING CONTROL REQUIREMENTS:  MSD recommends that those who wish to use the Atomic’s timing control feature first get the engine to run without timing control. Splitting the timing control into a secondary process will add very little time to the total install, but could significantly help with trouble shooting, should it be needed.The following are a list of items that are required to use the timing features of the Atomic system: An MSD Ignition control (such as a 6A or 6AL Ignition) The distributor must be locked-out (instructions included with Atomic EFI) An adjustable distributor rotor to achieve accurate rotor phasing. The balancer must be degreed or use timing tape on your balancer. EXHAUST AIR LEAKS:  The Atomic EFI is extremely sensitive to air leaks in the exhaust system. Any air leak between the engine and the WBO2 will cause the Atomic to have false readings, which can lead to poor engine performance, misfires, and an inability to properly auto-tune.
