Welcome to the board....I'm not going to beat around the bush.... Due to the influx of internet posers who claim to have cars that can do "this and that", we must now individually ask you series of questions to better determine if your lying or not. Please take no offence to our skepticism, the posers have ruined it for everyone.

1. Did you dyno the car or did the guy you bought it from say it made 408rwhp?
2.Where was it dynoed?
3.What pistons are you using and whats your compression?
