I know this is quibbling in the details, but no 370z has ran a 12 second quarter mile and when they starting getting close to hitting the 12's, people will be quibbling over thenths of a second.

I love my Z, but they are just not that fast....At least until someone gets a forced induction kit to market.

Sorry man got my mags confused here is the link. Its was C&D. Also the auto did 0-60 in 4.6 seconds and did the 1/4 in 13.1 @ 108mph. That is the fastest time recorded yet for the 370z. Im betting that at a prepped track an Auto 370z will be close to hitting 12's @ maybe 109-110mph but Im probably being too optimistic. Teh mags dont test 1/4 at prepped tracks thus my argument for the 370Z doing better numbers at a dedicated 1/4 facility. This is all speculation however but with the C&D results it looks like a 12 sec bonestock 370z is at the very least a probability. Thus also my entire arguement as to why a full bolt on 370z may just give that V8 M3 a run.

A bone stock 370 straight off the showroom floor, of either transmission type, isn't going to hit 12's even in ideal circumstances. I find the C/D numbers questionable honestly. My runs were 13.4xx in the 7AT, and that was with bolt-on power mods (Gen 3 intake, headers, HFCs, CBE) at a DA of ~1500, on a really good track (Houston Raceway Park). Granted, I had some extra junk in the car (large bag of tools, etc) and didn't mess with my tire pressures, but still ...

Soo you got two tests. One with manual and the other with auto and both are low 13's at over 107 mph, on a typical unprepped non 1/4 track surface, and you still dont think this car has a probable 12.9 in it on a prepped track? All it has to do is knock out a good 60' time. 108-110 mph can be enough to hit a 12.9 if you kill the 60'. It may take one hell of a launch but its at least "possible" imho. But until its done cant really disregard what you have said either. I guess time will ultimately tell.

BTW you have Sport/Touring and auto. Maybe that little extra weight cost you a few 10ths? Maybe?

Car in this test I believe only had the sport package I believe and I have no idea what the da was where they ran.

I'm not sure how they're getting those numbers, but they're not gonna happen on a completely showroom-stock 370Z on a real track. Perhaps they're using some method of estimation for their results that doesn't jive with a real track's timing methods.

You may be right Ive heard one of them uses some form of correction factor. Not sure on the particulars of that other than it sounds liek they make up numbers based on variables instead of cold hard test numbers.
