Seeing as i am in a realtivly good mood tonight i'll give you a non sarcastic answer.
If you fit an electric supercharger you will see about 450bhp. You should have saved a bit more and got an 07 car, twin intakes, twin superchargers = 750bhp
real answer = depends on what mods you have done
More patience than me tonight clearly Ian
We're not being nasty mate, and Im sorry if we have came across as a hostile bunch.
But you have to understadn you are asking quesitons that have been asked many times before, which is why I say USE THE SEARCH FUNCTION!
And depsite telling you an answer to a question clearly. You ignored it and asked something which I had already answred.
I hope you enjoy your Zed as much as I have mine, and I hopeyou get the power you want.
