Default OS 18 or SIRIO .23

I have pretty much decided to go with the .23 for my next motor but i would like to know if any one can tell me how easy to these motors tune, how well they keep a tune and which one is easier to tune. I read about this in the forum a while a go and i cant find it so im sorry if its a repost. thanks

I would say the TM, I have had personal experience with this engine and it ranks right up there with one of the best engines I have ever bought.

sirio .23. if you put a trinity pipe on it, it is unworldly fast.
it is easy to tune, it has so much power you can run it a little fat and still wheelie down the back straight and blast out of corners. i didn't think it was that fast until i put it in my revo last week.
it was way faster than my LSP with a wasp .28.

Allright i have the sirio .23 it is the greatest engine ever.i have gone through 2 gallons of gas and have never blown a plug.you should see the look on people faces when they see a 13 year old kid whoop their ass around the track.No other pipe will work with the .23,it does not get enoguh pressure to the fuel line,just get the traxxas blue exaust and it works perfect.I have never blown a plug or overheated.

your saying u have a traxxas pipe on the .23 and thats the best no other will work. I might be misunderstanding you but didn't trinity make a pipe with there own engine in mind? so wouldnt that be the best own for it? the trinity pipe is the best out there from what ive read and been told anyway. feed back?

the stock traxxas pipe does NOT work well with the .23 , I know , I ran one , it starves the engine of power , if your running the revo stock pipe with this engine , you dont know what your missing

as far as the trinity pipe , great pipe and now comes in a kit where you get the 2.5 header and stinger , or a BB header and the stinger screws out for the BB guys

well, my revo with TM323 would get destroyed by freez' beast, and my TM323 would destroy a sirio .23 ( drag raced 2) So if i were you i would go TM323. or just go full BB.
