the panoz is a monster. last year, at the now defunct dc alms race we were next to the panoz pits when the fired up that bear. it like to knocked you down. the sound reminded me of a P 51 fighter plane. the luodest i've had was at montreal at casino turn one of the saubers rapped his throttle coming out of the turn and banged my right ear so bad i couldn't hear for a week. cool!!
