Has anyone tried an 086 on the Fire 11? Looking at an RB 086 with the bent header..

I tried n 086 once on the Fire but it was when the engine was in a truggy and it did not have enough bottom end rip for me at my altitude.

I run a 9886/41021 when i need more bottom and an ofna 086 which has a short dbl bend manifold for more topend in truggy. But it's a clockwork modded engine that has had the sleeve dropped down to deal with the stockers excessive exhaust timing. It's one of my favorite engines. The stock engine suffers from a soft bottom end just like Chris eluded to.

Well, I already have a nearly new 053 that's just been sitting around for about two years.. Maybe I'll just try that, or an 0801..

The 053 will give you more bottom, but I think the top end will fall off, and it will just be all bottom. The 801 will probably be your best bet. How does the 2045 work with that engine?

Years back before the C6 was out, we all ran the WS7, and we used the 086 pipe, in buggy, very control able, with tons of top end.

WOW.. my fire 11 has too much bottom end

My F11 was too much bottom end for me in a buggy, it felt perfect to me in truggy!! Altho it just doesn't make the same awesome power my trusty old C6USA does so I stick to the USA for truck. I think a lot of guys run on really high bite tracks with a truggy and they need more bottom end.

Chris, how does the 2045 pipe work on the F11?

I think it works great and is what I ran on the Fire almost all the time. On some engines the 2045 almost tones down the power too much but with the Fire it felt perfect to me!!

What header were you using with that pipe? 192?

I ran the 192 header on it for both car and truck. Never did try a 198 as I never felt I needed any extra bottom end. I did also try one of the Tecnopower pipes on the F11 and that ran awesome as well!! Very similar to the 2045 and it had the same shape/length header as the RB (192)

Tecnopower pipe, I have one of those also, 2034? I think.

I got an Orion 2057, with a pipe adapter, to make it longer if needed, how does that pipe work? Is it much different than the 2058 pipe?

Thats the TP pipe I did try and liked!! I have never ran a 2057 but I think it's an older pipe design. I know the 2058 works well but not sure how the 2057 compares to it. I would say between the 2045 and TP pipe you would be good to go!!
