RB did make a .23 and a. 25, the .23 I believe was made for the Traxxas Revo, didn't really sell to many to the Revo guys, the. 25 was a monster, was not fuel efficient, but it was very fast.

I smell a new BXR over the winter!

beeeeeexxxxxxxxxxarrrrrrrr eh ! LOL

Get out hosehead!

Hey Rob, what is the main bearing size for the F11? I'm looking to replace it with ceramic bearing.

Just ran my Fire 11 on the track for the first time - in my RC8.2. 2058 pipe, stock AE clutch, stock gearing. Ran into some tuning headaches.. Kept cutting out. Today was probably 8-10C colder, and more humid than the last time I ran and had a decent tune, but on a parking lot. Even then it was cutting out sometimes. Weird.. Anyway, after lots of back on forth on the needles and changing in a new C5TGC I got it sorted.. Really good engine. Was comically rocket-like on the back straight. Not enough room even to really open up. Next time I might even go down on the CB... I think it's probably accurate that a Fire 11 is too much for a buggy.. Was fun though.

On a bigger, more flowing track it'd be really wicked.. Unfortunately the local track here is a short-ish, treacherous minefield..

Tony, mine has a 14x25.4x6. But who knows if they're all the same, lol.

Never mind, I found it.

Amain is showing the same size you quoted. Did you see the 2097 pipe Rb has out now? It looks like a 9901!

Yes i have. A guy i race with has a stock F11/2097 in a truggy. It's tamer than the 2045 IMO. Probably good choice for slick tracks.

i am going to test the 2097 tommorow..... i will report back....

I would guess, it depends on the manifold you use, on how it works, the RB manifold looks long. maybe like the 41021 or 41020?

Sounds good, do you think it looks like the 9901 pipe? what about the header length? What engine are you trying it on?

it looks like a 9901 or 9853...the manifold is very long, I likely wont use it but rather 410001...the engine will be a clocked BXR

I didn't think it looked like 9901. My friend uses a 192p and so do I. I use 9886/41001 also.
