What pipe for a RB S7 .21 engine?

if you can get by on milage, i always liked a jp-1 on this motor, it gives it a noticable boost on the bottom, but you will be pushing it to go 7 min. on a tank of gas.

RB 9863 pipe is the two chambered loder version of the 2045. Less restrictive and plenty of bottom end. JP-1 is a fuel hog. Pair it with a short round header.

+1, when i was running this motor before i started running Trinity products, i researched this a bit and the other option seemed to be the RB2020...if you can still get one im not even shure... it was supposed to be the bottom end pipe from RB

With the JP3 pipe durning practice im getting about 7-8min. I am only running local club races and in the 10 min heat i pit at a 5-6 min window, and i use the same 5-6 min window durning all mains just to be safe with no flame outs. I would rather take an extra pit than have a flame out.
But i might try the 2045 pipe and see, Anyone tried the new JP6 pipe yet?

Try this pipe it really wakes up the bottom end and gives great run time. I can do 9 mins easy on my S7.

So would these pipes work on the S5 to? I have a jp3 that im goign to put on my S5, will it have good power and bad fuel mileage like ive heard?

i think the s5 has a better bottom than the s7 but dont have the top end, so pipe selection could be different. i think the jp-3 is a mid to top pipe so it should work ok.........but then again i ran the s7 for a while never tried the s5......to get the best milage you need the RB pipes.....at least thats what the experts (RB) say.....

On the S7 i run the JP-4. It gets the best bottom end and race speed of all of the pipes I have tried. I have prefered the Losi RE-11 as of late for fuel milage and smooth power band. It will push 10 minutes with a 7mm restrictor.
