Fyi , i have NEVER once been underpowered using 2096 41021 setup ,EVER and no im not a slow guy , i dont "bash" my cars in a field , I RACE RC CARS
I have had issues with bearings in chassis that made it feel like the engine sucked ,put 4 or 5 engines in and they all did the same thing , replaced all bearings and voila , issue solved , felt free with no load buuuut ....... Viva la novarossi |

How does the 41001 compare to the 41020? Not on this specific engine, but just in general? |
Today I tried the 2096 vs 9901 and I preferred the 9901 although I'll probably not buy it.
With the 2096 you sort of have a "lag" between the moment you pull the throttle and the engine reeving up. It's small but with the 9901 the engine feels way more connected to the car. It's instantaneous. Funnily the 9901 was faster in the straight even against the 2096 + almost 1/2 leaner on the HSN. Weird as everybody agree on the oposite. The 9901 is much louder. Apart from that the lap time was pretty close and not worth me rushing to buy the 9901. Maybe when I'll have some spare money laying around... Thanks again for all the help |

With a P5xlt ?
The bearings have all been changed with the P5xlt and are regularly checked one by one every two weeks or so during the full disassembly for cleaning purposes. So I think I'm clear for this problem (gear mech is ok too everywhere and I'm using the std spur with a 13t pinion) . I just don't understand why my engine doesn't sort of leap forward like the other guys do :(. The lsn has been set 1/4 turn rich when the engine started to be a bit lean. It was actually set 1/8 leaner than what I have by the local pros but I found was then a bit of a pig to start. I'm going to strip the clutch to double check the spring thickness. Thank you again for all the inputs ! At least thats what it sounds like If youre richening your lsn to get rid of a "lean bog" youre doing it wrong |

9901 less topend, different bottom end.. I just don't like it much. |
We tried on both my mate's BTT4 and my P5xlt with two separate 2096 so it's unlikely a faulty 2096 I think :(.
He retuned his BTT4 when he changed the can (going from 9901 to 2096) he had to lean quite a bit. I didn't change much my tuning going from 2096 to the 9901 the top end was ok but it's true the LSN (?) was a tad too lean you could almost hear the engine bog but only at the end of the long straight when closing totally the throttle at full rpm. Wasn't sure to touch the lsn or hsn and as it was just a lend I didn't wan't to upset my original settings, maybe I should've been braver. One thing I discovered yesterday is that I'm the only one with a 13t bell... everybody has a 14t on their car. It could help as the surface is very slippery (1/2" very thin dust on hard pack almost like flour). |

And here is another graph from the same engine comparing the 9901, 2096 and a RB 2097..
