I don't think the dude is stock, i think he just has a stock clutch. I didn't hear a chirp either, btw.

Guys have run 13s in 3.0s NA (I was the first one to ever do it btw, more than 10 years ago now lol nostalgia), Dandymax even got in the 12s in his NA 3.0 with cams and worked heads. There are plenty of 3.0s that have the power to get there, whether or not they have the driver or traction to get there is another story. Bolting parts on to your car and messing around a bit with a VAFC is easy. Drag racing is easy. Drag racing really well is not.

I just think it's funny how he's talking all kinds of smack and has no hard numbers to back it up with. He's got all kinds of street racing tales though, as if running some joker on the street means anything. I hope he comes back with some good numbers, more fast maximas are always a good thing. Not going to hold my breath though. Guys come on here and talk about how fast they are all the time, and then disappear from the .org a month later without ever producing proof of how fast they are.

Only when it was cammed.

If he is bragging about chirping i saw a 240 with no mods just a stupidly aggressive clutch chirp 4th gear....nothing to run home about, it was actually stupid. My car with cams and a stage 2 clutch chirped 4th.....WOW, ground breaking stuff we are talking about here. Car still would have just run 14s with the tune it had.

now if he spun 4th that would be a different story. My old turbo car did that once on 215s on summer tires when it was FREEZING outside so it kinda doesnt count but still.

i got nothin to prove. i was just trying to point out to everyone that they could easily experiment with ram air intake setups its not expensive at all and you could build your own custom setup for under $50 bucks. throttle response is improved and highway driving is fun in 6th passing is a breeze leaning on the gas if you leave the vias in place. this is my daily driver i'm not about to go break something trying to prove a point.

wheels are light 19s on fat rubber no low pro nonsense the only thing stock is the clutch/flywheel

so i talked some smack like you arent big whoop take it eezy fellas dont release the hounds im allergic to dogs

Yeah, I should've clarified my post a bit by adding the line "with stock internals". Of course if you upgrade internals you can get the VQ30 into 13's. The 12 second N/A times that have been brought up, I refuse to believe with N/A engine even with upgraded cams or anything else.
I don't even think the stock body is able to go that fast without forced induction, due to drag resistance, so unless you did some serious weight reduction you really just can't run 12's in any N/A VQ30, stock internals or not. You would need ~ 300WHP to get the VQ30 into 12's, and you're not running 300WHP on any VQ30 without forced induction. I think the highest WHP for an N/A VQ30 (DE-K engine) that I've seen around here was ~ 270whp IIRC, and you're not running 12's at those #'s in the 5th gen body, an N/A 4th gen with weight reduction and ~270WHP can maybe do it, but those don't exist.

My statement holds true. You can't run 12's in ANY N/A VQ30 without forced induction. And you can't run 13's on any VQ30 N/A without upgraded internals and/or good bit of weight reduction. You can, however, run low 14's all day with built up N/A VQ30 on stock internals and no weight reduction or very slight weight reduction. The math doesn't add up, you need somewhere ~ 300WHP and under 3000lbs to achieve anywhere close to 12's and this is with perfect driving and perfect traction.

The 2011 M3's run mid 12's 1/4 mile, having the lightest V8 ever produced with the following stats:

- Power (SAE): 414 hp @ 8,300 rpm;
- 295 ft lb of torque @ 3,900 rpm
- Curb Weight 3600 lbs

That said, I'd be willing to bet $1000 that there is nobody able to run 12's in their N/A VQ30 Maxima, and I don't care how much you build up the engine internals or how much weight reduction you do. Without forced induction/lots of Nitrous, a N/A VQ30 is simply not doing 12's in the 1/4 mile, ever. Unless, you take apart the whole car and leave it as just a shell with very little weight, it's just not possible.

Stock internalled, mild headwork Cammed VQ30:

So I got out to the track yesterday, managed to get 7 runs in and set some new PB's across the board on pretty much every 1/4 mile stat. I had a few issues during the day with traction and even some clutch slip now (uh oh) so I wasn't uber consistent but not too bad.

Anways, the new best sixty foot is a 1.73, and best ET and trap is now 12.61@108.98. My runs went as follows:

Run . . . 60 ft . . . 1/8 ET . . . 1/8 mph . . . .1/4 ET . . . .1/4 mph
#1 . . . 1.8020 . . .8.2049 . . . .85.40 . . . . 12.7579 . . . 108.17
#2 . . . 1.7501 . . .8.0960 . . . .86.50 . . . . 12.6130 . . . 108.98 <---- bold = new PB's
#3 . . . 1.7611 . . .8.1882 . . . .85.68 . . . . 12.7510 . . . 107.95
#4 . . . 1.7608 . . .8.1177 . . . .86.20 . . . . 12.6489 . . . 108.16

45 min lunch break

#5 . . . 1.8401 . . .8.1332 . . . .85.71 . . . . 12.6820 . . . 108.46
#6 . . . 1.7738 . . .8.1527 . . . .86.03 . . . . 12.7218 . . . 107.09
#7 . . . 1.7372 . . .8.2161 . . . .84.94 . . . . 12.8351 . . . 106.39 <---- bold = new PB

I was really disappointed in #5, since that was the run after the longest cool down break of the day, and I got stuck in the lane I don't like (the left), that always sucks and gives traction problems off the line. As you can see the car ran pretty strongly that run once it got going, so with a 1.75 sixty foot or so that pass would have been a high 12.5...

Runs #6 and #7 I had issues with some clutch slip, unfortunately. Not severe but you could smell it afterwards and my ET and mph dropped quite a bit on those 2 runs, although I did manage to somehow hit the 1.73 by playing with tire pressure. So #7 was a bummer too, because a good launch like that should have gotten me a high 12.5.

Here's the timeslip for run #2, and as always I have video but don't have it edited together yet, so that will be added in the near future. All in all, I'm happy with the results but being only 2 hundredths away on the ET and trap from a 12.5x and 109.xx was a little disappointing, and I do feel the car is capable of it, although I would say that's just about the limit, unless I can somehow drop half a tenth further on the sixty foot.

Soild 12.6 @108mph. That car dyno'd at 270whp aswell for a little while it was the fastest N/A Maxima, full interior at that. I believe it was sparks that broke its record IIRC, then the 3.5s started taking strides at cracking 11s N/A, Aaron92SE is working on that as we speak.

You are unequivocally wrong. Myself and quite a few others have run 13s with 3.0s NA without "upgraded internals" (I went 13.42 on slicks and 13.82 on street tires back in April 2004, and 96sleeper was a few hundredths of a second faster than me on street tires, he went 13.79 or 13.78 or something like that) and Dandymax ran 12.6 NA with cams and head work after that. Dandymax always ribbed me for my car being lighter than his because it was a 96, and all my car had removed was the passenger and rear bench (40lbs for front seat, and like 10lbs for rear foam bench). I was thinking he was full interior but I just looked at his old thread and he removed the passenger seat and had a racing seat as his driver's seat, so that's probably about 65lbs of weight reduction. I believe 96sleeper is a big guy even iirc.

I'm sure Dandymax would be happy to put that $1000 you are willing to bet to good use, since what you are saying is impossible was done like 6 years ago, lol.

edit: edited info on dandymax's car after reading his thread again.

Im really interested in trying this, can you explain what sensor you are taping into to get the manifold pressure readings? And please also get a picture and circle this sensor on the manifold after the throttle body so I can make sure I am working with the right sensor
