I got to race my Clockwork modded JL .21 today at my local indoor offroad clay track. The power is there! The throttle response is so smooth but can get violent if you grab a handful of throttle. This engine has no lack of bottom end that is for sure. With a Dynamite 086 I was able to easily do a 8min main and had at least another minute in the tank. Engine ran consistant and held a great tune all day. My temps only got up to 208 on the exergen temp gun. Unfortunately, I was not able to get any video but I impressed alot of people today with this engine.
