very KOOL!!!

I just got done reading the article in XRC about head clearance & tuning with shims. In our lil .12s what is the magic number for head clearance?? And while we are on this topic... what about .21 engines as well

Thanks Dino for bringing this forum to us !

Ah,was this Dino's idea?

Yes,because I don't need to spend many time to search engine's threads.

Questions on fuel.

How much % oil ( Castor / synthetic) content do we really need in our Fuel? I have heard from as low as 3% ( wow!) to as high as 18%.

Which is better, more castor or more synthetic?

I just used a very bad batch of fuel
very bad......

corse-r might want to share his valuable insight on fuel.

Hello buddy,
You need to set up a new thread.

Corse-R

I've just answered to this question on the fuel thread, you're welcome to ask anything you may need on those thread.

But will tell you that Castor oils are more suited to withstand with high rpms, a synthetic oil burns at a lower temperature and leaves none, castor leaves some residues that still lubricate and saves you from a very big ouch at the end of the backstraight.

This should be a very cool forum, I have been out of nitro for a while, but just getting back in, so I dont know what the hot engines are out there, but I can share my knowledge in tuning still

Hey kitracer, you and I had a short discussion on fuels... Which fuel is this are you referring to?

Synthetic oil provides less friction than castor oil due to it's properties. So for serious racing, more synthetic oil is better. For bashing, more castor is better as castor protects engine better.

I believe in the recent 1/8th WC in Ohio, Team Kyosho used 4% of oil in their fuel. This is actually another way of getting a higher percentage of nitro methanol in. Of course this is strickly serious racing and when the sky is the limit when it comes to piston sleeve replacements !

Sorry to pinch your bubble, but Castor oil protects a long way more than Synthetic, because after burning, keeps some residuel that still provides anti seizing protection (Synthetic, just not). Just ask to MS who is now by those forums how much Castor he used on the last Euros in Madrid with more than 35ºC air temp and engines going to sky-high when to temp is related (just a hint: he used more Castor than synthetic, like did Andrea Rossi with their Sirio engines and others...

Castor is the ULTIMATE when to high rpms protection is related, just ask it to Kart racers and MX racers.... and their engines spin at roughly half the rpms than our engines (Some kart engines can spin up to 19000 rpms).

The main tradeoff for Castor and is why is less used is because he leaves residues on the engine, but afterall those residues are fine and shows you how fine is burning your combustion chamber.

There is already a fuel thread!

BTW,EVO where is MEGAs thread? Are you take sides....

EVOLUTION

We will let Salven personally come and start the novamega thread!

Or maybe we need the master to start it,where are you manti?
