DC-9-11 and DC-9-15

[1993matias]

May I ask what the difference is between the DC-9-11 and the DC-9-15?

As I can see, they both carry 90 passengers at 487 knots a distance of 1310 miles since 1965 costing 33,769,031 and using 738 fuel. The only difference is the engine, which apparently is named P&W JT8D-5 in the -11 and P&W JT8D-1 in the -15.

According to the greatest DC-9 books of them all, Squadron/Signal DC-9/MD-80, the difference lies in the engine. The -15 (i believe) has more powerful engines for hot and high performance, compared to the "Standard". Of course, nowhere as powerful as the DC-9-20 which featured DC-9-30 wings and engines.
