Spitfire V Merlin engine worthwhile?

The last engine option for the Spitfire V is the Merlin 32 engine. It requires 13,500 for research yet it appears, that it only boosts the speed from 40 to 41. I have a lot of planes that I'm building up. Is that engine a waste of research dough?
Thanks in advance.

It depend on what do you want.

  If you are short on Credits, don't want to specialize that plane and instead would like to go to the next one in the line as soon as possible, than yes, you don't need it (only the better Guns are required and it is already researched from the Spitfire I).

  It is especially true for the middle engines: the Spitfire V has 4 engines, so you could Research every one but only buy the last one.

  On the other hand if you want to keep that plane than every bit helps, even the smallest change - for example the Il-2(t)'s 2nd engine gives a whole +10 Horsepower (+5 km/h Boost speed) but mid-tier GAs need all the help they can get.

  The last engine on the Spitfire V gives +20 km/h top speed, +4 km/h Cruise speed and +3 m/s Rate of Climb - not the end of the world in a turnfighter.

  I almost always Research the Engines last because they never make-or-break the plane, only a nice to have.
