Sorry to bother you with another re-engining post, but I'm wondering what modern engines could be used to completely re-engine the 727. I know RR Tays have been used, but what other engines will fit in the center hole and produce adequate thrust?
I'd imagine BR715s would work, possibly PW6000s, but will any other engines fit the center hole?

UPS uses the Tay in all three positisions. Check out the modified #2 engine intake with the "hump".


You're only as good as your last departure.

The 727 super 27 mod that Sun Country uses I think uses the -200 version of the JT8D... I think. I don't see any reason why a JT8D-200 would not work in a 727

The UPS conversions with BR715 fits in the holes of the short 727-100. But they are not considered powerful enough for the long 727-200.
The "Super 27" conversion of the 727-200 consists of JT8D-2xx on #1 and #3 positions, while the centre engine is retained as a hushed JT8D-15/-17.
The JT8D-200 is too fat to fit in the centre position.

AtlasAir is right about the RR Tay in UPS B727-100. I was wrong about the BR-715. Sorry.

You couldn't fit a BR715 on a 727, at least not the centre position, the engines have a very wide fan for their size. The Tay is the right size, it is also used on the F100.

Rolls Royce are looking at new deriviatves of the BR715 for the 717-100 and 717-300. They are also looking at a derivitave engine to re-engine MD-80s with which will probably fail to meet Stage 4 rules.
