Re: Which Motor
 

I bet the following legal motor is better in all aspects,

NRS-RR12L3 L3 Long Stroge .12 Engine

Just to make it turns smoother... Making the inner hub diameter bigger(to host the thrust bearing) is more important than putting that bearing in between.

make the diff turn smoother or the car overall?

It will sure to make the car overall... but if you are talking only putting the bearing in that spur gear which will take a difficult work (to make the bearing sits absolutely center), just do the other parts (bigger inner diameter and polishing) that generates 95 percent of the smoother running diff aspects.

I one of those guys if it aint broke don't fix it. the nova mega work so good in my impulse for 6 years no problems, i won't to stick with nova megal. Michael S turbo motor legal and which one do you think?

what are your thoughts on the 3racing diferential gear. do you think it will be smoother compared to the kits plastic one?

how can i have the hole bigger?

thanks!

2105MCP should be the better one among your choice. Is Maxpower MAX-MX12MAX5MF NOVAMAX U/C 2,1cc 5P.TRB also consider legal? RR12L3/L5 will still have more power from low to mid range. I believe this is the engine that Fukuda (and Swager?) gives MS someting to remember on winternats...

Our concrete wall is stronger than 710 ??:D :nod: :nod:
Been there, done that... many times..:lol: :lol:

You just too fast, the 11.347 is unbelieveble !!
For others information, another fast guy in the second fastest lap is only able to makes 11.746.

45T Aluminum Pulley? it will never be since those diff balls will be in friction directly with aluminum. Using those aluminum pulleys will make the tranny runs smoother...

Bring it to the work shop.. a decent lathe machine should be able to do it. Furthermore, in order to help the bearing sits in the real center of pulley, bring used drive belt to cover the tooth for lathe`s chuck to hold the diff gear (45T) better. Idea courtesy from Gold Finger...

pyramid, so the alum 3racing pulley is not a good idea?

Ummm, that's a sensitive issue ! :lol: More like % nitro at work.

Anyway, I think Rene C gave a report on the Pre-Worlds at Brazil. He mentioned that the engines used by the Japanese (assuming those were RR12L3 Kondo ones) were around the same as what they had.

;) If you need any help, you know where to find me.:lol:

Man Salvens excuse factory was working overtime there. If the Mugens were running 40% why did not he? Is he not Serpents best racer? How could the "unbeatable" Serpent factory team get out motored? It is no excuse in my book, he just needs to accept that the Serpent guys had not done their homework on that weekend when it came to motors, the Mugen guys had the car speed.

The pre-worlds was run to IFMAR rules, 16% nitro. This will even up the playing field when it comes to "funny fuel".

Hey Pyramid, next time slow down and don't assume the 710 is invinsible OK?:sneaky: :lol:

That looks like the old rear shock tower doubled up. I think the new 3.5 mm single piece rear shock tower is stronger.
