For USD$200 below - The Sirio EVo2 is a screamer, i have the new EVO2 5 Port AAC, run it in WOT for 3 tanks, put it down on the track and race tune it for the next 2-3 tank, my car fly and have no problem catching those guys running JP NS12S5. The new carb is also very nice and easy to tuned.

My last Sirio AAC last me about 4 gallons and I expect it to last longer but unfortunately a blown plug spoil it. However I do have the new JP FX-12 5 port will get it run in and test it side by side with my EVO2.
