72 Dart Swinger 3.6L Pentastar +T5
I was curious to see how the 3.6L Torque and Hp curves compared to common 340/360. I couldn't find a decent factory dyno curve of an old combo but the factory used a different SAE test standard back then anyway, so I replotted a 1999 5.9l Magnum.
Stock for Stock, the Pentastar loses out between 1500-4000rpm but kicks in after 4k and pulls hard to its peak Hp at ~6500rpm.
At 5000rpm, the little 3.6L is up a whopping
150ft-lb and
20hp over the 360!
By 6000rpm the Pentastar hits its peak Hp but the 360 went home early.
4.56 rear end should help out the low speed torque and keep the revs in the power band, while the .63 over drive will turn those rear gears into a cruise friendly 2.87,,,

I had two friends visit my project yesterday, both are ex-Chrysler Australia Engineers who also did time with Chrysler in Detroit. One of them joined Chrysler in 1964, the other in maybe 1967. They love MOPAR and it's locked in their blood. They are both so impressed with the Pentastar 3.6L.
One of them keeps a Dodge Van with transverse Pentastar in the USA and travels from Australia then uses it for three summer months holidaying as though he were a Gypsy, every year … that was his intro to the 3.6L and it was unconditional and undying love within the first 30 minutes of driving it, and that has remained for the past 5 years. He's 70 years old and he'll be back in the 2018 USA summer yet again.
I have introduced them to this forum and they like it.
After the visit to my shop yesterday and lots of talking over lunch, one sent this email after going home to the other engineer who visited …
"It is a shame I do not have the Specific Fuel Consumption for each engine, which really completes the Pentastar 3.6L comparison with the Motori 2.8L Turbo Common Rail Diesel.
I love the flat torque curve (Variable Valve Timing) of the Pentastar, which is really noticeable in terms of the driving experience and fuel efficiency, like a diesel!
Also I would like to get hold of a plot of HP, Torque and Brake Specific Fuel Consumption for the un-liked 2.8L L4 VM Motori Turbo Common Rail Diesel in my Australian Chrysler Grand Voyager for comparison.
And to top it off for the Pentastar, 150 kgs and so small. A real shame we couldn't get that Pentastar in the Australian Chrysler van.
That 'myduster360' graph picture tells the story, a great story!"
So, MD360, for the Chrysler 2.8L L4 VM Motori Turbo Common Rail Diesel, I wonder where we can get the same info you plotted in your V6 vs V8 graph. With that info, we'll have enough info to carry us through another lunch engagement. :-)
