It boggles my mind how much $$$ it takes to make the viper motor fast in our trucks. I loved my 06 QC but i'll be honest, my new diesel with just a programmer $500 and a trango kit ($100) is faster than my srt10 would have been with $4K in mods. To me it just doesnt make any economic sense to make an srt-10 FASSSTTTT. The $ to horsepower ratio is brutal and they are just too heavy to be a fast contender, let alone safe on the streets at high horsepower...i.e. handling characterstics and traction. Just my 2 cents. Im just glad the srt-10 boys dont spend all this extra money they got on diesel upgrades or the diesel world would be a whole new ball game. Spending 20k on a diesel in upgrades would be insane!
