how is this different than sniper? is atomic better? after holley bought msd.... how is one better than the other?

[@KalaniMusic]

Where do you place and secure all the wiring?

[@exotecpro90]

is there any additional information on the fuel line plumbing? which fittings are required to connect the fuel lines to the MSD atomic 2 body? is it 2 times -6AN female?

[@djverhulst]

I like to have one of these on a Chevy C20 350 small block

[@6T7CAT]

Will the system adjust timing as well??

[@aw9680]

I liked the pwm fuel pump of the atomic 1.

[@ericholden1888]

How do you set these up for a roots blower- this kit need to come with better instructions

[@serpentza]

Will this be CARB legal like the original atomic efi?

[@ethanmoss3136]

No

[@jefferyliang1941]

okay this is sick, I want one and I don't even have a car !

[@brentonk461]

Nice if you're going to give me one to try, but I can already tell you that even two 255 L/hr pumps still won't flow anywhere near as much as one maxed out Holley blue pump.

What part#is the ford kickdown adapter

[@kevinkuhlemier5823]

Never buy a Efi kit with the ECU on the throttle body Heat and vibration will kill it 2:46

[@ronsmith7739]

This is a mass intake injection and is dependent on the intake manifold.

[@Jiggabuu777]

When paying that much for a system it should come with everything shouldn't have to buy accessories

[@dividingbyzerofpv6748]

Just admit it. This is a holley sniper that you guys rebranded

[@travisbeagle5691]

It isn't, at all. First of all, the atomic came first so if anything the sniper is a rebrand. Second of all, the way they operate is different. The sniper works like any port injected efi system, it just bolts on to a carburetor manifold. The atomic on the other hand uses efi valves and controls, but instead of just misting fuel into the intake, it uses venturies to thoroughly mix the fuel in the intake air like a carburetor. This gives you the best of both worlds.

[@wolfthornhawkridge5705]

That’s exactly what I thought looking at the hand held and interface. They changed the logo, WTF?

[@coolhandluke1503]

@@travisbeagle5691 What do you mean when you say efi valves and controls? It clearly doesn't have IACV

[@travisbeagle5691]

@@coolhandluke1503 It has an integrated IACV in the body. You can see a small, fifth air intake port near the rear of the valve body for it. What makes any EFI is having computer controlled valving for air and fuel to provide precise control over the air-fuel mixture. This has exactly that. The only other way to have any sort of control over the mix is to have a mechanically controlled system (like a carburetor.)

[@coolhandluke1503]

@@travisbeagle5691 Does the Holley sniper not have this? What I like about the Holley is the integrated fuel regulator.

[@TrentGustus]

Msd wouldn't sell at close to the price of the sniper because of the hand held, they didn't want to reduce the price of the reliable msd system against the more expensive sniper, so they made the msd into a sniper, buy the competition, then scuttle it.

[@anthonyhenley9570]

Brake vacuum on msd

[@Мистер_ЗМЗ]

Прикольная штука конечно, но блин дорого, да и дрючат в России за тюнинг.

[@Celticman197]

MSD Atomic EFI's are junk. First one I had lasted less than 500 miles, it was replaced with a new one which lasted less than 8000 miles. I have a Holly Sniper now, 100% better performance
