Well I did a search ...........keywords are too general to really come up with anything so I apologize for starting another topic .

I have a Axial .28 spec rr ....in a Losi......it's just a cheapy $160 motor but it runs real impressive , holds a tune well , and so on .

Only bummer is........ in offroad racing outdoor I am only getting like 5 1/2 minutes to a tank of fuel . I would really like to see 6 plus minutes only to get 1 less stop if I am ever fortunate enough to get in a 30 minute main I want to take advantage it . Right now I am running a Dynamite ht700 which is like a carbon copy of a JP1 ...........

Looking for your thoughts ...........the only pipe I won't buy is is one of the OS ones ............simply becuase they cost more than the motor .LOL LOL .

TT2035?? Ofna 086 ?? I am hearing all kinds of stuff .

Thank you all in advance for your replies . Dave

i have gotten good fuel economy with the tt associated 2035 pipe with every engine i have tried it on, another way to get better economy is to be smooth on the trigger, its hard to get alot of time out of a .28 but the jp1 style pipe definatly wont help with the issue

If all you need is 30 seconds, don't bother with a pipe. Add a big fuel filter, or go to a smaller venturi or add a head shim or drop the nitro %. All cost less then a pipe.

If your only looking for 30 seconds more run time, increase your fuel tubing, then top off the engine, after you prime it

Thanks guys.............. those are really easy cost efficient things to do . If I still wanted to get a pipe as well what do you recommend ??

I just got 10 mins using a jp4 with an eb modded v-spec.

Was bq got a horrid start went a lap down and decided lets play the fuel mileage game ended up 2nd and just bout won. Everyone I know with the jp-4 gets at least 730 run time. It does choke the bottom a bit(not a problem for me eb has to much anyway) but thats the price you pay to go 10 mins plus.

If you didn't have one of each motor available on the market, you could afford a decent pipe. Try the 2050 OS pipe I have, if you like it, find one that's close to the same.

werd on the 2050...

+1 on the OS pipes! They are the SHIZZIE!
But...
They are hard to find and cost an a$$ load!
Almost as much as RB pipes...

But they rock!

dead1dave,

Yeah, JP-4 does give super mileage. And yes, it does choke at the bottom...helps me out a lot from getting over excited while exiting the corner though

the os pipes work good on os engines, i have tried on a few other engines and they were not good for them, i would try the 2035 its cheap enough, and if you decide to upgrade your engine, it will work good on just about anything, i have run it on os speeds, grp, novarossi it was good on anything i put it on

The OS pipes are good no doubt. However they are fuel hogs.

JP3 i would suggest as well as goung down to a smaller venturi as the .28 has ample rip as well as maybe go up a tooth on the clutch bell to smooth out the power band.
Biggest improvement would be to discipline the throttle finger.
All other suggestions above would also contribute.
