Street- if many road hours are going to be logged i would go mechanical simply because it will last longer then electric...go with the deep pulleys if you go this route..nothing worse then throwing water pump belt after burning the tires off..
Strip- i would go Electric...
#1- it saves hp
#2- you can leave it running after car is back in pits..allows car to cool off
much much quicker....How much HP does this make up ????
you will know if it stops working...Most drivers including myself stay glued to the gages..if not you better...My oil and water gage stay in my side vision from the time i leave the line and 5 seconds later...
i knew what you meant Charles...lol
i run a CSR and i am 100% happy...it cost a little more but ..you get what you pay for...Plus it looks GREAT !!!..
