Here's a quick report on my new Stock FX12 T03. Wow is all I have to say. I ran two tanks through the car on the bench, warming it up to about 200*, letting it cool each time with the piston at BDC. Then i put it on the track and ran about 6 tanks, leaning it 1/8th after the first 3 tanks (didn't want to really lean it) and letting it cool each time at BDC. I didn't give it full throttle until the 5th and 6th tanks and WOW what an Engine. The engine never got above 215 and it was absolutely flying. It has monster bottom end and of course blistering top end. It sound like it reaches high rpm's VERY fast. I haven't even started playing with different plugs yet either. I was amazed. I had a guy with a Maxy Modified X12 Turbo out there and I had no problem keeping up with him. The track was loose yesterday so we couldn't do a true head to head test, but I like what I saw. I was a little worried that maybe I should have stretched the wallet and gone for the mod version, yes I've seen it in action, but I'm very happy with this "Stock" Engine (I put it in quotes because it's so damn fast.) Anyone considering an X12 or NSR12 Should definitely consider this engine. Can't wait till my next race!
