Problem - Slower than it should be.
Hi all. First post. I apologize if it is in the wrong section as I am new to the site.
I just bought a 2003 Enthusiast 350z with 70,000 miles. The numbers float around a bit, but online it says it should get to 60 somewhere around 5.5 or so. I'm consistently getting 6.2's. The only modification was a aftermarket grill that the previous owner put in and a K&N drop in filter I put in.
Does anyone have any idea what the problem might be?
Or a solution?
Is 5.5 a correct estimate for what it should be?
I'm looking to start adding mods, but I want to make sure I'm starting from a good baseline. WHY IS IT SO SLOW!?

While I appreciate your constructive criticism, I disagree. I know that you know nothing about me, but I know how to get a car off a line. There is something wrong with the power. It just doesn't seem to be there. Is it something that a tune-up could possibly fix? and what would it be fixing? I'm not a beginner at driving quickly, but I'm just starting out at tuning. Actually, I haven't started yet except for dropping in a K&N filter into the air box which is more of a joke than anything. I just want to make sure I'm getting the most out of my new car, that's all. And while it sounds great (still stock), it's not moving the way I know it should. Any help?

There's way to many variables on a 0-60 run. Worthless imo. Run it at the drag strip or throw it on the dyno. A general tune up can't hurt anything. Let's also not forget that every car is built different.

So an 11 year old car that might have been started thousands of times would have the rings, cylinder walls, bearing clearances, cam lobes & much much more stuff in the same condition & performed as an almost new car that was tested by car magazine's expert drivers in 2003 ????
OK.

If your car normally runs well (as it should with only 70k miles) but seems slightly off the mark with full throttle high RPM sprints consider checking for proper operation of the knock sensor. It could be that Knock sensor is pulling the spark timing back from full advance at high RPM.
A man in my neighborhood has a Subaru WRX sti that was more than a match power wise to my Z. On a long steep hill near us I was able to not only pull around and pass him, but I kinda blew his doors off as I went by. It turned out an overly reactive knock sensor was the problem.
I don’t know how you can check for this. Or even if this is as common an occurrence with the Z as it can be with Subaru’s, but both cars use a very similar system.
