Noir that's a rather misguided attempt to fix problems with the BOB scenario. There are far bigger problems.
I think you read a claim on these forums and parroted it back. I don't think, however, the claim is all that noteworthy to begin with.
There WAS a variant of the 110C-4/B that had DB601N engines. These produced 1200 horsepower. The variant before this produced 1175 horsepower. Total (2 engines) of 50 extra horsepower. Not all that much. However, the 110C-4B had extra drag due to the bomb rack (the "/B" denotes it's capable of carrying bombs).
The small increase in horsepower was only to make up for the lost speed in drag. The 110C-4 and the 110C-4/B were almost the same top speeds. If you removed the draggy bomb rack it would only add about 15km/h.
However, there are a few things to note.
A number of sources say the top speed of the 110C-4 was about 348 or 349 at 22k. Ours makes about 345 at 19k.
This (citing 2 sources) shows 110c-4 top speed separate from 110c-4/b:

always the best but in this case cites 3 different sources at the bottom:
http://www.airpages.ru/eng/lw/bf110c.shtmlNote it says the engine type and speed of 560km/h, not too far off from what we have in-game.
Here we see AH's performance tops off a bit under 350 at 19K or so:

http://bbs.hitechcreations.com/scores/genchart.php?p1=59&p2=-1&pw=2>ype=0I find this VERY strange since in older versions of AH charts supplied by HTC we found the FTH at about 23k or so. The Musketeers archived one of these on their website here:
http://www.musketeers.org/kumori/images/110c4speed.gifNote that the speed didn't change, just the altitude it best reached that.
On ww2aircraft.net and LEMB there were some comments about 2 types of superchargers on the 110C. The "early" models topped out 4km (4000 meters altitude), and the later were 4.5km. It looks like we have been given the early FTH, but we have late-BOB full-powered spits and hurricanes with +12 boost and 100 octane fuel. Note that the 1100 hp version of the Bf110C was from 1939, as well. This was the same DB601A engine as found in the Me109, basically speaking.
In short: I think somebody read something on paper and freaked out, assuming that's what we had. I think the performance difference is minimal, even IF we had it. In fact, it looks like HTC hamstrung the 110C-4 at one point by lowering the FTH by some 4,000 feet. I don't recall when that happened!
Please consider this plane was a very very early introduction to the game. HTC made several compromises back then to enhance the planeset and include more functionality. We had a K-4 they named a G-10 just to give you more guns options. We had a hybrid typhoon. We had gunpods and bombs on the Bf109F-4. We had bombs on the Bf109E-4. We had a frankenstein Spit9. The P-47D-40 was really first named P-47D-30. Not all aircraft were 100% correct in their naming or their loadouts.
It's most likely they modeled a normal Bf110C-4 and added the /B on the name just because it has the central bomb rack, allowing this plane to perform over a much wider scenario time frame. A Bf110C-4 on the eastern front or in the desert would be nearly useless without its bomb load. HTC could get away with making combined capabilities back then. Today they have a much stricter adherence to specific types.
In short: Quit freaking out about the 110C-4. It looks right compared to all the references I see online. The DB601N issue is a snipe hunt in regards to BOB performance. The real problems are the Hurr1 overmodeling and the bombers being too fast for RAF fighters to chase.
