Default Which Axe Rossi?

I saw pics of an Axe Rossi's sleeve and internals on here the other day that looked insane. I am interested in getting one now but can't find the thread I was looking at now. Which one is suppose to be the fastest?

I have a Cobra and Cobra Evo, they are their flagship motors... not insane top end power but good race engines, can stick with the best of them... good fuel economy, easy to tune, hold a tune well and if you look after them excellent longevity. Easy to get 30 - 40 litres out of them.

Yeah gotta agree there, I have a mamba and it has had around 30 litres put through it, and still has good compression.

The Mamba is more of a tuners motor though, not as good for a beginner... still an excellent motor though.

So the Mamba is harder to tune and not as fast? Sounds wonderful.

Wauw, 30 - 40 liters!!
Did you replace anything on the engine, like bearing, conrod?

Please tell your secret to get that many liters through them!

I changed my Cobra's internal with the X1 intestines because there was a crack in the conrod's bushing, after 7 gallons.
The engine became impossible to tune.
No power when cold and rich and become too lean and stalls after several minutes caused by the heat.

Also replaced the bearings with ceramics version.
Runs like a dream now. I have 1 gallon through it and just want to extend its life as long as possible.

I must say, I ran the Mamba for quite some time and it was excelent. It was VERY easy to tune and dial in. It was a rocket on the top end, it actually has more top end than the cobra but a little less grunt. The AXE engines have insane pinch out of the box so if you dont plan on replacing the rod after the first gallon I would use a heat gun to get it nice and hot for the first 1 or two gallons.

Great Mills.

Change the bearings and conrod every 15 litres, dont run them lean and the Cobra will serve you well.

The mamba is still easy to tune just a little harder than the cobra.
