I'm not experienced with the losi clutch.
However, I would look at a softer spring for the 4 port motor over the 5 port. This should also help with mileage, though it isn't going to be some miracle that'll give you an extra 2 minutes.
Truth be told, there's no single miracle cure. It's in car setup, throttle control, track size, and then it will fall back on mechanical things.
Personally? I'd be happy with 7-8 minutes. 1 less pit stop is only advantageous if you never crash. A single crash and you've lost your advantage.
