I understand that a single turbo is going to make more power... The goal of this wasn't to make a large amount of power, if that was the intention, I wouldn't be starting with a 3800... The goal here was to do something that hasn't successfully been done to this point. You can find Grand Prixs for $1000 all day now, why not have some fun and see what they are capable of? The only downfall is that the used market seems to be gone, so more fabrication and creativity will be required.
