Hmmm...are you running the small SVR batteries? Their internal resistance is too high and they heat up fast. If you're running 16ah (13.5 lb ea) Hawkers, I don't understand why they heat up so fast. John Wayland runs those all day long with 250 amp dump charging in between runs and they get hot but not 160 degrees in three runs. People sometimes wonder how I can get a 3200lb car at only 144V to do 14.67 in the 1/4 mile. Having two 8" motors helps, but the big thing is really the two strings of 42ah Hawkers (800lbs) that barely notice a 1/4 mile run and give a combined 1400 battery amps out of the hole. Dennis, the CE weighs lass than half what my Dualin'7 weighs. I bet the right string (right size) of Hawkers would give you the consistant 12.0 second runs you want. Of course it's always a challenge to go faster. Keep up the good work with those ICE guys. Rich Brown
