I've now managed to build ships with over 100Km/s delta-v and useful thrust.
Meet the fastest ship in my Courier class, the "H" model. Fully fueled, a Courier H has 137Km/s delta-v and space for 48 passengers! Weighing in at only 690 tons, it slips easily into any spare space-ship bay so it's always ready for weekend trips to the tropical Venusian Trojan asteroids! A steal at just 10.3 mega-credits! (other uses for the Courier H include: lighting small moons, or powering large cities!)
So I propose a race. Who can do the Homecoming mission in the least amount of time! So far my best is 6M 10D.

Well, just ran this mission again. The Courier H got the transit down to 4 months and 28 days.
Setting up the rendezvous burn with Mars is a challenge. Ideally, you's be able to adjust the start of the burn earlier or later. But until that feature is added, I've found that splitting the burn in half makes it easier to get the timing right.
Also made an NTR design to try to see if a slingshot close to the sun is faster.
Christ! Finally got a gold-star on this mission using a 1GW methane resistojet ship. It's hard to go fast on this mission because of celestial mechanics! I have a lot of work to go to even start competing
It's amazing how quickly dV requirements escalate the further from a Hohmann transfer you get
Theoretically it should be possible to do it in under 4 months. But that would require some very efficient and tight maneuvering. This took me a few tries, and even then I am still wasting a lot of deltaV. The "shuttle" has 437 km/s DeltaV and little over 5 mG of acceleration when the tanks are full. The thruster has an exhaust velocity of 200km/s and is powered by 7 modified 24.7 GW Apophy's reactors (173 GW total). The first version had more deltaV but slower acceleration. If you're building ships with a lot of deltaV I recommend keeping the burn time at around 1 month. I sacrificed about 50km/s deltaV, but I compensated that by pulling more Gs, which in this case means I reach max velocity twice as fast and have an easier time making the insertion burns.
So, now that we have drop tanks, can anyone make an even faster ship? Or do those drop tanks not have a meaningful effect when your design is already this extreme?
Drop tanks should help, They'll make it easier and cheaper to get a large mass-ratio. May also make the braking burn easier due to higher acceleration after dropping the tanks. That said, Tukuro could already shatter my 3M 4D record with the ship he posted. He just needs a better trajectory. (which is why I posted my trajectory with my last record)
Bravo Apophys, bravo. You crushed the 3 month limit, and gave us a very nice picture of your trip and ship to boot. Excellent showing sir Apophys. Someone clearly felt, and delivered, the need for speed. Remind me to call you next time I need to get anywhere fast.
Well, 2 months 13 days is the record, and it seems to have been achieved on a fairly good rout. It looks like you already are thrusting along almost the entire length of the trip, which seems to suggest whoever the next winner is will need higher thrust, possibly more so than they will need higher delta v.
But, enough of that, everyone give a hand and thumbs up to Apophys for the greatness he's already achieved.
