so it's been a few years since the Pug
0:02
engines the pentastar upgrade engines
0:04
that is have arrived and they got
0:06
revised heads with new cam phasing twole
0:10
valve lift and a lot of friction
0:12
reduction there is no direct injection
0:15
even now and what's kind of funny is
0:17
that they're still selling the original
0:19
engines as well as the pugs so the nice
0:21
thing about the upgraded engine is that
0:23
you get 15% more torque at low engine
0:26
speeds and better gas mileage on the
0:28
Grand Cherokee 5 more horsepower came in
0:31
and on the Challenger already by 2023
0:34
you had 305 horsepower from this engine
0:37
which is pretty good so the two-speed
0:39
variable valve lift reduces pumping work
0:42
at low speeds and doesn't sacrifice top
0:45
end power a new torque driven cam
0:47
phasing valve timing system Cuts oil
0:49
demand and is hard to talk about and
0:51
increases its range from 50° to 70° the
0:55
valve timing was re-calibrated to take
0:57
advantage of the new intake manifold
1:00
other updates include cooled exhaust gas
1:02
recirculation or EGR a new intake
1:05
manifold with longer Runners for higher
1:07
torque boost higher compression from
1:10
10.2 to 11.3 to1 new fuel injectors have
1:14
eight holes to atomize the fuel better
1:16
and there were a bunch of things they
1:18
did to reduce internal friction so
1:20
overall they managed to cut 4 lb out of
1:22
the engine down to 326 lb kind of makes
1:25
you wish that they would only make the
