Doh said:thats not too bad then, just gotta convince the missus
do you have any video clicks of said "cannon fire" ?
Not yet but I will give it a try. I just have to find a place to drive the ass off my car at night with somebody behind filming and not get arrested. I did get it once when stationary. I bounced the engine off the rev limiter when I accidentaly pinned the pedal to the floor getting out of the car. The result was lots of flame and an engine check light for air intake volume out of limits. I don't really want to do that again! I think the Alpina does it because it has a tendancy to dump raw fuel down the pipes on overrun and of course straight through pipes do nothing to contain the burn. Might be something to do with the high lift cams, they tend to cause a rough idle too which is an unfortunate side effect. Oh well, can't have everything! I might try to record the sound from inside the car over the next couple of days, that would be a good start I suppose.
