Wolfhound V.S Tweakscaled Terrier

[Misguided Kerbal]

This question has been bugging at me for a long time. Which is better, the Wolfhound, or the Terrier tweakscaled to 2.5? Sadly, I don't have making history, so if you are willing to, could you test out the differences?

the wolfhound, because of It's MUCH higher Delta-V (412 on the Xbox, I think) and cool looks/name. of course I don't have tweakscale, because I play on le Xbox, so, can someone tell me how much thrust a 2.5 meter terrier has?

Definitely the wolfhound.  Pretty sure the Isp is 380 vs. Terrier 345.  TWR on wolfhound is better than terrier also.

For OP engines through Tweakscale you should usually scale down, because the bigger parts are balanced with better economy of scale. In this case however there isn't a better vacuum engine in the game for most use cases (unless you use a 2.5m LV-N or ion). A 2.5m Rhino would mass 6t and have 1333kN (calculated, not checked). This will still normally be worse on grounds of higher mass and lower vacuum Isp, but on a sufficiently massive stage it would be better purely down to lower gravity losses.

Assuming you won't be landing with it, you should compare it to a non-scaled Terrier if you want a real competition. I have regularly found the Wolfhound to be a poor choice for deltaV on deep-space engines. A poodle will even beat it on smaller 2.5m crafts.
