I am curious if this motor is at all related to the IRL or older CART motor.

Probably not, CART motors are turbo 4 cylinders and IRL are pushrod lumps.
IRL motors are NA 3.5 DOHC V8s. Naturally aspirated. They were 4.0 liters until 2002 I think.
NASCAR is still pushrod. NHRA is still pushrod. The Pontiac and Ford (I think) motors in the Rolex series are pushrods. The GTOR, C5R and C6R corvettes still run pushrods.

CART motors are DOHC 2.65 liter turbocharged V8s--some teams use a turbo fed by only one header for oval track racing. Have been for over a decade.

The paddles shifters for the Acuras, yes the article is long, but what are ya gonna do:
"Electrically-operated gearshift system to be supplied to Acura endurance race teams
Motorsport engineering specialist Zytek is to supply their
electrically-operated gearshift system (EGS) to Acura teams for their
assault on the American Le Mans Series next year. Acura will be involved
with three teams in 2007, all competing in the LMP2 class using 3.4
litre V8 engines fitted with EGS.
The Zytek EGS is lighter and simpler than alternative pneumatic or
hydraulic systems and the all-electric operation offers reliability,
straightforward integration and improved gearbox life. The EGS can
produce individual gearshifts in less than 40ms and up to five
downshifts in less than one second.
The precise movement of the electric actuators also means that there is
very little wear on the gear selector mechanism and dog rings, extending
gearbox life and improving reliability and shifting accuracy. The fully
electric approach removes the need for a separate hydraulic or pneumatic
system, reducing vehicle mass and complexity. Once fitted, the system is
essentially maintenance-free and there is no potential for leakage of
air or hydraulic fluid.
The EGS requires extremely precise control and state-of-the art energy
management. Zytek has made use of its long background in control
electronics and software and the electromechanical design expertise of
its electric vehicles division to engineer a system which can operate
reliably in the most demanding race conditions without excessive power
consumption. The EGS control unit includes built-in energy storage,
which accumulates electrical energy from the vehicle alternator between
gearshifts and delivers high power extremely rapidly for a super fast
shifting action. All system components together with the control and
calibration software have been developed in-house by Zytek.
Zytek's EGS has already demonstrated its reliability after successfully
completing a combined 1.8 million shifts in the first season of the A1
Grand Prix series. The lightweight, high performance system has also
been used on Zytek's own LMP1 sportscars in 2004, 2005 and 2006 in
endurance racing worldwide, as well as the renowned Le Mans 24 hour
race.
Following the conclusion of the new deal, Zytek's motorsport products
applications manager Phil Lord said, "We are delighted to be working
closely with Acura for ALMS next year. Our EGS is well suited to
endurance racing, providing downshift protection over long distances to
prevent drivers over revving their engines. It can cope well with varied
driving styles, providing a more consistent performance for endurance
racing."
The new contract with Acura will see Zytek working closely with engine
specialists at the Honda Performance Development facility in Santa
Clarita, California, to ensure that the EGS interfaces well with their
new engine before official testing. All three teams with the Acura
engine and Zytek EGS will be racing for the first time at Sebring ALMS
in 2007."
