Well as promised my bro arrived at my work on tuesday with his imporved GSI. The bottle of Nos looks like a divers bottle in the back of the car but he assured me that it made a noticable difference. The induction Kit sounded great it was like a fighter plane flying 200 feet above your head. It looked like a massive flying saucer under his bonnet Custom made for him by the wizards of NOS but did it make a difference other than noise.
So the badgering started come on finish your work I want to see if it is quicker than yours. So evetually I finished and got in my signum. I would like to point out at this point no speed limits were broken . SO we started our journey home, I was in the lead. As I came off a roundabout I give it throttle my brother was 50 feet behind me and guess what that is where he stayed he could not catch me even with the induction kit giving him another 8-10 BHP. Rather disconcerted he phoned me on Hands free and said I cant catch you this is C**p . My reply to this was what a waste of money.
Considering he had the nos in his car less than a week he felt he should not have run out. But you guessed it he had . So after spending another £60 on a refill we went to see if his car was faster. This time I have to admit defeat he did out accelerate me to 60 and I reckon he was about 100 feet in front from a standing start to 60 . It is a bit rough but his 0-60 time is about 6 secs. Respect to Nos but I think that it is a bit much to pay for 6 miles of pure speed thats how much the guy at the garage reckons it would last on all the time.
So GSI vrs Signum with out NOS the same with NOS Beaten.
Respect to my BRO for spending all that money just to beat me.
