So I have concluded that dual stock systems is a really nice way to go. I've been running it on 2x6s this whole time and its been great runs about 130mph, and rarely cuts out being I don't speed run it, I stay in the throttle hard start to finish on a battery. Tried 2x4s today and think I like it more as primarily I parking lot bash and race with many other friends on the weekends. No real need for me to make this a dedicated speed run car. It did 80mph, I stayed deep into the throttle the whole time two different battery full charges, 100% batt all the way to lvc. 0 over amp cut out and very very low heat. LOVE IT!!! I think I might build my limitless the same way.
