I run an Orion engine and i can barely make 7 minutes. Are there any tricks to getting more minutes out of 1 tank?

-Lean out the bottom. Tebos youtube vid helped me a ton with tuning.
-use the right tires, no fishtailing around the track
-drive smooth, not drift
- thinner clutch springs, grippier shoes, maybe even a steel flywheel
-absolute correct pipe for engine even if it's a $100 OS pipe
-drive on a smaller tighter track

There are many variables. Roll resistance of drive train is a part. Clutch, fuel, engine tune, pipe/header etc... How you pull the throttle. EPA set-up, Carb insert. Even the surface you race on and size make a difference. I don't know what you use and where. Never mind how everything is set-up.

Ignoring everything else you are probably running the engine to rich. But you can't just ignore everything else and expect to get 11-12 minutes a tank.

i know my engine is tuned properly and im using the pipe the engine came with. I dont expect to get 10 minutes out of a tank but i know i should be able to get 8 minutes but anything less than 8 minutes hurts me in my race because in 30 minutes if i come in at about 8 minutes i only have to do 3 stops but anything less than that i have to do more stops.

Use a inline filter cools gas and can ADD ABOUT 30 TO 45 SEC to run time check out Adam Drake tips team Losi also you can wrap your gas tank with metal tape to keep your gas temps down check out lutzinator.com Ryan Lutz Team Durango hope this helps

I am working on a small scale version of one of these... it will slide into your carb in-place of your venturi.

You can add a 30 to 40 sec of run time by keeping your fuel cool add a cooling filter check out Adam Drake Team Losi tips on You tube also you can wrap your gas tank with metal tape to keep the fuel cool from the pipe and body of the car check out Ryan lutz tips at Lutzinator.com hope this helps a little with run time or you can switch to a Alpha A852 with the aplus 0801 pipe guaranteed youl get 10 + min a tank and an easy long lasting tune

Also can check if there is a limiter in the tank,if the track allows this then you have an extra minute right there.

That's a Tornado fuel saver for full-size cars... they were a huge rage about 5-8 years ago boasting more MPG and power, but never worked because the intake manifolds themselves are designed to smooth and optimize airflow. When independent media/companies did testing, they actually reduced HP and increased MPG on some cars.

I doubt there'd be any significant gains on our cars, just because of the nature of 2-stroke nitro engines.

lol i knew that had to be a joke.

Theres no way it worked then, and i cant see it doing anything now but falling down the carb. Surely there is a lot of turbulence and flutter in the crankcase, which is well beyond the carb. Even if it did work in 1:1 i cant see it working here.

As mentioned a proper tune goes a long way. It may be slightly leaner than you are used to, but leaning the bottom end a tad helps some. Dont forget about your pipe. It can make a huge difference in tune and mileage!

I havent tried the pressure line cooler/filter yet myself, but there are plenty of folks boasting about an extra 30 seconds give or take.

If you are willing to try it, you might want to try a heavier flywheel and/or a lighter clutch spring setup also.

There's lots of little things that pair up to increase tank time.
