Thinking of suitable pipe for my coming WS7II that will run on a medium sized track. I'll say bottom end is the play. After reading many, I'm quite confused. Many commented the 063, JP-1 and T-2050 are good with this motor, but never mentioned about the length of manifold to use. Someone says WS7II cannot blast like S7 at the bottom end, unless getting a longer set of pipe. So, that guys recommended to adapt a longer manifold. But I didn't see JP-1 and OS had a longer manifold on the market, expected RB. Now, I have my choice here, RB 063 with short manifold and T-2050. Is longer manifold really the case?

hi,

i got a s7 (not ws7) and rb 063, 086, 1 peice inline, 2 peice, power adapter and jp2, i got pretty much all the pipe the combos that are available, and the s7 just doesnt have alot of bottom end as other engines.


it is just adequate enough for a bit of 4 wheels spin using a 13t bell on hard loose surface i run on.

kind regards
J

You can use the RB Long Header on any of those pipes you stated. They are compatible.
