I need the best bottom end pipe/header combo for my Bonito in my truggy. Small/Med sized track not a lot of run up length to the jumps. Please advise, thank you.

I have a 9853 and understand increase of bottom end with the 41005, but I read the 41021 is more for top end right?

9853SS/41005 is pretty unbeatable on a stock bonito. 41021 will stifle topend.

personally I thought the 9853, 2084..41005 and 41021 all performed poorly on the stock Bonito.... We run on high grip and these combo's made the engine feel very soft..From every bit of testing I have done with the Bonito it prefers to have the shortest manifold possible, especially if you are wanting it to make good power with lots of snap....The longer the manifold the lazier the engine feels and responds....

note. Lower traction conditions can make the engines react differently...How early and how hard the engines are put under load can change how different pipes react and feel to throttle input....

on our track conditions there is no other combo worth running but a 9886/41001/41019 on a stock or modified Bonito...this combo gives the best bottom end kick with the largest overall powerband... SO if you are running on higher traction I wouldn't be looking at a 2084 or a 9853 or a long manifold...maybe its great for slick tracks, but for anything like what we have those combos are not that good.....The very first time I tested a Bonito it was on a 2084/41005 and my first thoughts were that no wonder nobody likes these engines as it had no pop whatsoever. But as soon as a 86 and short manifold were put on the engine woke right up with all kinds of bottom end power and snap.... true story !

Thanks for the guidance Neal. I will be trying the 9886/41001 with my truggy/Bonito. I also will take your advice on the clutch setup too. Much appreciated :)

I was thinking of putting a Novarossi KEEP OFF 21-4 4-Port in my truggy. What pipe/manifold combo would you recommend for tighter/smaller tracks?

Thanks.

My Novarossi pipes and headers look like crap. Is there a polish out there anyone can suggest from experience of making it "bling" like it did when it was new? Kinda bums me out lookin at it!

Hello! I use the Novarossi 2096 pipe with the 41029 (short manifold for Mugen) and 7,0 venturi in my Maxys Cinco BT. What will happen to the powerband if i change manifold to the 41001 manifold? The engine realy came alive when i changed venturi from 6,5-7,0. But for my local track i need some more power in the midrange powerband. When i come out from a pretty high speed turn i need to go to full throttle to clear a huge jump. But when i go to full throttle the power realy isnt there. I often land short.

I have had good luck with the crock pop with coolant to clean off all the crud from the pipes. I then use the abrasive side of a dish sponge and it gets them pretty good looking again. Not the exact same pop as a brand new pipe, but a good 90-95% of it back.

Yeah, I used to do that. I was hoping someone ran across a good polish and could save me time/money.
