I have a Fiesta RST and wish to install NOS in the car as I want the immediate surge of power it delivers for overtaking. I want to run about 40 bhp of NOS on top of the 185 ish I have in the "engine"

I phoned up my insurance company asking about this and Boncaster said they could no longer insure me if I were to install the system!

who insures cars running NOS and what are the excess and prices I should expect!
