The Atomic 2 EFI system
from MSD features 4, 100LB/HR
Fuel Injectors capable of
supporting up to 650 HP
naturally aspirated or 635 HP
on forced induction
applications. The Atomic 2
ECU is capable of fuel map
self-learning and ignition
timing control, improving
idle stability, drivability,
and wide-open throttle
horsepower! Designed to fit
on 4150 intake manifold, with
ample clearance for factory
air cleaners.
The
Atomic 2 EFI provides the
performance and drivability
benefits that you expect from
fuel injection. Quick starts,
smooth idle and great
throttle response just to
name a few. Combine the fact
that the Atomic 2 will
support ignition timing
through the ECU and you have
a win-win combination.
Initial timing is handled
through a compact handheld
monitor where you simply
answer a few car guy
questions about your engine
and you're off and
running!
