First off, let me say, this is my first non-Mustang "sports car" I have owned, so please forgive my ignorance about the car. I just bought a 2003 350Z 6 spd Touring with a Vortech supercharger/intercooler on it. I was told by the guy I bought it from that the car has 500 hp. I told him over the phone that I found that hard to believe without a built motor, (and at only 10 lbs of boost). When I went to look at/buy the car, he showed me a dyno sheet, but it looked very generic, (no shop name, no vehicle printed on it, etc...). The car has headers, mid-pipe, utec, 650cc injectors, fuel rails, walbro fuel pump, and I think that is about it for engine mods.


My question for you more experienced Nissan guys is what would you give as a ballpark guesstimate for this car given the mods on it. I a nmot asking you guys to dyno the car over the computer, just give a rough guess what you think it should be. The car does feel pretty quick, but not that quick.

One last thing, who tunes these cars with utec? Keep in mind I am in Gainesville, and don't mind driving to Tampa, just would like to not go too far.
