Frankly, I agree with Ranzear: At -least- mention that you are using highly modified thrusters, because otherwise you are not setting a reachable standard. The reason I am dismissive of this creation is because it is not anything like actual space rockets in that it's fuel canisters would long exhausted from that many engines. The fact that you have a limitless supply of fuel with the fuel collectors -and- a far higher trust engine, means you could reach any speed and any distance. It's well known that the e-xxxx line of engines was modified to provide unrealistic thrust, most of the other added mod parts are more in moderation.
