im not an expert but my friend with a gn has one gn doing 9s. then he did a whole new setup. now he has a twin turbo gn. he did a 8.xx in the 1/4 and should be breaking into the 7s within the next couple weeks of tuning and wat not... i have a couple other friends with twin turbo v8s and they are doing 9s and daily drivers. i heard both that either on or the other is better... i wouldnt mind seeing 1 or 2 on a contour...
