I'm just wondering why I don't see anyone in my area running theses motors? I race in the northeast area.
i used both , the Factory tuned and the RS 3 ports.
I used the RS 3 ports during my last race and 3 days racing without a single glitch.
The RS 3 ports has a tremendous power , very linear , a very good bottom and very decent top speed.
Fuel efficiency is good and manage to pit at 9 minutes and i have a 10.30 to 10.45 runtime.
One of my good friend is using the RS 5 ports and he is more than happy with this engine and already completed 3 races. The engine still have a very compression.
i used also the Factory and sorry to say that the gap is significant between the 2 engines and my Factory did not last long unfortunately.
I am using also the Alpha Lutz and Dragon and difficult to compare engines together , but regarding the pro & cons , the Orion RS has a better fuel efficiency for sure (even the 5 ports RS) and the running temperature is far lower compare to the Lutz (130 to 140 celcius for the Lutz and only 105 to 107 celcius for the RS 3 ports) . after saying that both brands are not so bad at all.
if you have the choice, go for the RS 3 or 5 ports IMHO.
Cheers
