It has the oomph but I think I could use more bottom end. I've ran it with the 9886 so it could be the reason. I will try another pipe later when I have the chance.

other brand rods break because they aren't tempered good like Nova and OS, and not the same quality.. and Nova make RB so.. I wouldn't worry..

As a matter of fact, I just remembered. One guy did indeed lose a rod on an RB C6 about a month ago

Use a novarossi R7 rod,The Rb rod is a 5.02mm crank pin and will not fit.

Man I'm really tempted by that RB Rally engine to put in my buggy for shxxs and giggles.. Just got some Amain discount codes too. At minimum I'd get 12 bucks off - it'd be like $178... I guess if it's a rally eninge it's designed to rev high, with not so much torque, so I assume something like a 2013 torquey pipe would be good for it......

that engine is likely the same as a Fire 11........The Fire 11 was just a offroad dressed Rally 11....

V19 has Nova crank and nova rod with smaller pin. At least mine does.

And on road motors traditionally have way more torque than off road motor, as the cars have the potential to generate a lot more grip and actually use the power.

I have a friend that runs a Speed in his buggy and it's pretty nuts.

Kinda wish I had gotten the Rally instead of the V19 as it's gonna most likley end up in my truck.

Herrsavage 02-07-2014 11:21 AM

If it's a F11, it at least doesn't have the good front bearing... However much a difference that makes..

The Rally also says 14.5mm crank, the Fire 11 14mm....

Herrsavage 02-07-2014 09:51 PM

BillyT, you don't like the V19? Not enough for truggy? You had the V11 right, and loved it?

BillyT. 02-10-2014 09:31 AM

V11 in my truck was cut. Been running it with 6.5 nitromizer insert in buggy to slow it down.

Verdict still out on V19. Just haven't had enough time to run it...

Herrsavage 02-16-2014 06:06 AM

Just got three tanks through that used Fire 11 I got (and had pinched..) Ran great.. The 2045 (with different, longer header) was kind of lame. Put on an SH "High Torque" pipe, and it was much better. No EFRA number, so not raceable I guess.. Need to get me a 2013 pipe...

aznitronut 02-16-2014 06:22 AM

Try the 2058 pipe on the F11, I ran it on mine, I got over 10 minutes on a tank, using it in the new Losi T 3.0 truggy.

Herrsavage 02-16-2014 06:28 AM

I have a 2058 on my other Fire 11 in my RC8T for racing - love it.. For bashing around in the SC8 though I want something with more top end.. The 2058 is great on a track, but it's not quite the top-end screamer I want this other F11 to be.. Though yeah, I probably ought to have something with an EFRA number on it, in case I need to throw it in my buggy or truggy at some point..

aznitronut 02-16-2014 06:35 AM

Try a shorter header on your 2058 on the F11, that should give it a little more top end. I don't think the 2013 will do As good as the 2058, have you tried the 2086? That's more of a top end pipe.

Herrsavage 02-16-2014 06:40 AM

I have an Ofna 086 on a Nosram/Picco.. Might try that. Like this SH pipe so far though..
