People can say whatever they want...that's what makes this forum so great... Personally, When the owner of a 80's corvette that I'd been racing on I-75 last weekend (and beat by the way) pulled in behind me at the gas station and asked what was in it. I got a big ol' grin when his jaw dropped when he found out he just got his *** handed to him by a v6! He didn't believe a 6 cylinder could go faster than 145 mph and made me prove it to him!!! (he actually tried counting the spark plugs!) Before I get angry mail saying I'm dangerous let me say it was in northern michigan where you can see down a straight e-way for miles and miles!! By the way, when they say x-fires are good for 155...believe me...they are good for at least 163 mph. (my buddy's a state trooper and clocked me on laser!)
