There are alot of variables.

engine/tune
pipe/header
tires
driving style.
track conditions
crashing

How long are you trying to go and what are you doing now?

First I would try a smaller carb restrictor then you can turn down your endpoint on your carb. Works for me.

+1.

Also, are you running the RTR pipe? If you are, chuck that thing in the trash and buy a new one. Any one. It is one if not THE most unefficient pipes known to man

Ditch the .28 and grab a good .21 engine....most racers run a .21 in Truggy for that reason. Runtime is much better and the power is just as good.

Reedy 121vr, Werks B5, something like that.

Smaller restricter and reduce your EPA on the throttle. Most pros run only 85% throttle, so they can run leaner, thus getting better fuel mileage.

That engine is a gas HOG. If you are serious, you need to look for a .21. I run a stock Nova p5 and get just under 9 mins per take..

Most times 85% is all you need. Depending on what size restrictor used, full throttle can be as low as 60% of full movement. Once the throttle barrel clears the restrictor, you don't need to pull any more.

I was n your situation. When I started I bought a RC8RS RTR. It came with the .28 that u have. It had great power but really loved fuel. 5 to 6 min was it! There no good way to stretch the time much on that engine. I tried pipes, retstrictors with some gains but just not worth it. U can get a Werks B2 and a pipe(can b used pipe to save money) and you'll get 10 plus on a good tune. Or for a little more power n a truggy, try a B5. Unfortunately, if u want more run time, you're gonna have to change engines. I sold my .28 with prostart for 100 bucks and that'll at least cover close b half of a new engine/pipe
