I'm running a NR Toro Nero with 30% nitro, medium plug(McCoy), and a JP-3 in a D8. It runs beautiful and handles great. Trouble is I'm having trouble making a 7 min run. Will switching to 20% make a big difference. Any other suggestions?

JP-3 is a fuel hog. Good pipe to get a tune with it, but it has poor economy. I suggest running a different pipe and you'll be surprised. In my Go 3-port I was having trouble with 6-7 minutes as well; when I put a Dynamite 007HT on and re-tuned I gained 2-3 minutes.

the pipe is probably your problem.for a cheap pipe try the ae 2035.i got 10 minutes and about a 1/4 tank of fuel left in my truggy.i am not a fuel mileage minded driver either.temps were around 230.

no jp pipes on novarossi!!!!
use a 9853 w/ 41001 or 41005 , for budget use ofna 053

Yup try different pipe, go smaller on the carb insert and try to be smooth on the throttle.

Thanks a lot. Ordered the 053. I'll see how it does next race.

I'm having the same problem as well although it could just be because the engine is pretty new. I ran my first races on Saturday and was barely able to make it through the 6 min. As a matter of fact, it ran out just as I finished my last lap on my second race. I am running a tuned GRP .21 and a Dynamite 053 pipe.

just an fyi, I ran a plus 4 with a losi re11 pipe and it ran great.
10 minutes in buggy and smooth. have yet to try any nova pipes but for some this may be an alternative.

Mo,

did you pit at 10 minutes also? Did it have enough bottom or just controllable. Give me some info as I am trying to find an alternative to the Nova pipes.

Whats the reason behind not using JP pipes ?

thirsty, jp-4 is not that bad. but the RE11 gets my vote. I get close to 11 min on a v-spec.

Go to a 6.5mm restrictor and try the Trinity Big Boy pipe. That really helps with fuel mileage. I am getting 12+ with my Murnan Modified +4.

Same here...RE-11 is the same specs as the OS 2050 pipe which is no longer made. I can get 10 mins as well depending on the track with the v-spec. Another option is to limit WOT to 50-75% so long as top end is not sacrificed.

I have heard 20% will help, but have not tried it.

rfleck and i race together and he was the first to make the 10min heat with no pit stops. i did give him a hard time about the 4 feet of fuel line in his car, but had to shut up when it teched dead on at 125cc. but both of us can make the 10 minute heats. i use the stock 8mm restrictor and can get full throttel if i need it, i'm not sure what restrictor ron is using
