Which pipe is better in fuel mileage, JP-2 or......
 

I have a Jammin JP-2 pipe and Dynamite 007HT

Which would be best for fuel mileage?

Engine- Novarossi N.21R - hot modded

Track- Dirt & clay, hard packed.

THANKS!!!!

both will suck the fuel, the JP2 may be the best out of those two, but a dynamite 053 is the best IMO ;) ....

check with the person that modded the motor....they'd be able to tell ya better than anyone....but i'd say use the jp2 for larger tracks and the 007 for shorter ones....that's my .02

OK, so that 2 for the JP-2 pipe, Its a pretty fast track but the only place to hold the throttle full open for more then a second is the straight away, about 40 years maybe less, still JP-2 pipe?

yes... the 007 pipe is pretty much useless IMO, i have one and tried it on a bunch of engines and tracks and never ran it for more than a take, seemed to have power for 5 feet and then be slow and also killed run time... the Nova you have loves the 053 or 086... medium to small tracks the 053 is perfect. had a stock and mod version (murnan Modified) of what you have... i could pit at 8-9 min with a heavy HB and jammin x2 truggy with the 053 and gave the power from bottom to top... alot of novas seem to like the 053... just my opinion though
