43.7 pounds to be exact of extra wieght(+the no2/co2 bottles)  ,not to shabby considering its worth 100-250 hp depending on how high the boost is set.the intercooler isnt that tiny ,it just hard to see its size in the pics.and its not twin turbo,its only a single turbo setup for now,until i get my real tim eprogramable ecm,and do the speed density swap
edit btw i got rid of the ac stuff to offeset the wieght,i just gota buy the right serp belt so i can ditch the ac compressor now
