kengeorge:
I have had an idea to bring back the TSR.2, and need some advice about what engines to power it. Are there, or have been a comparable turbofan built in the West to rival the Olympus BOl.22R Mk.320 that was intended for the TSR.2?

GTX_Admin:
What era are you looking at?

apophenia:
If you mean fully modern Western turbofans, the the closest match for the BSEL Olympus Mk 320 is probably the F110-GE-132.

BOl.22R Olympus      F110-GE-132
Reheat turbojet      Reheat turbofan
L = 152.2 in (no A/B?)   L = 181.9 in
D = 40 inches      D = 46.5 inches max
Dry = 3,615 lb (no A/B)   Dry = 3,920 lb
T/O = 30,610 lbf reheat*   T/O = 32,500 lbf reheat

* Some sources say 33,000 lbf 'wet' for the Mk 320.

kengeorge:
The era I'm looking at is around the early to mid eighties. If there isn't anything suitable then I'll go with the Olympus as in the original. I did consider the Orenda Iroqouis, or a Conway with afterburner as an alternative.

GTX_Admin:
Given Concorde is still in early service at that time you could just use a variant of the Rolls-Royce/Snecma Olympus 593 to get both greater performance and known capability.

I wasn't able to find the full length (with AB) or Weight (with AB) of the Olympus MK.320 but I am going to hazard a guess that they would be close to those for the RR/SNECMA Olympus 593.  Based upon this, and looking at the time period, I believe the F101-GE-102 which is the engine from the B-1B would be a good choice.  It's thrust might be a little lower but if you factor in probably much lower weight and more modern capability and probably better SFC you would come out on tops.  Plus having some commonality with the USAF can't hurt.
