lol please refer to the other post where I posted several dynos of 5.5gen and 6th gen Maxima as well as V6 Altima, as well as Accord V6 and TL/TL-S. I understand every dyno is different and conditions will affect how cars perform, that's I didn't just post one dyno, but several dynos from several sources to ensure accuracy. Based on those dynos the Max/Altima makes about 190-220whp, torque is at a pretty constant 220wheel lbft for most of the plots (which indicates Nissan was possibly underrating the torque, this was also suggested by Maxima owner/engineer), however, hp seems to be overrated. Note that early 3rd gen TL 5AT puts down 212whp to the wheels, I think it's safe to assume that TL-S 5AT puts down at least 10whp more (given that TL-S 6MT has 20-30whp more than TL 6MT, again refer to those links I posted before). Torque wise the TL 5AT puts down about 200 to the wheels, which is indeed less than the Maxima, but the TL-S 5AT, I believe it would also put down at least 10lbft to the wheels more than a regular TL 5AT. Also again, as I said earlier, the transmission in 2007 TL AT has been beefed up a bit and is also more aggressive than older 3rd gen model, all these little changes add up IMO.

I think most Nissan drivers think their cars are faster mainly because of the torque advantage, I mean it's the torque that does the work in city driving etc. I mean I've driven a 5.5gen Maxima a lot when I was working as a lot boy (not just parking it, but actually drove it for long trips too) and I know how that torque felt. But rev it higher and it just didn't feel as torquey, still strong, just not as strong as at low to mid rpm.

As for the 5.5 gens and their dynoed power, most 4AT 5.5 gens make about 190-195whp and 210wtq. Some as high as 200whp. The 6MT cars make about 10whp/10wtq more. Let's also not forget that the 5.5 gen only weighs 3,200-3,250lbs too. With headers, ECU, and a couple other simple tweaks, it's very easy to put the 5.5 4AT into the 230-240whp range. Weighing in at 3,250lbs, the 5.5 gen 4AT with 240whp have the same power to weight ratio as new TLS 6MT if it's really putting down 255whp. There are 6MT 5.5 gens with 260-265whp with just bolt-ons and a little work to the intake manifold.

dave. since you know so much about infiniti/nissan. i selling my TL. I am thinking about the g37 . people say the g35 is still faster than the g37. the g37 is a rip off though. fully loaded for around 45k. about the same price as the 335s and is350. gonna go test drive a g37 this weekend. people say it does 0-60 in 5.6 seconds and 1/4 in 13.8 ? i believe? not sure.

dr_brains510, thanks for the support! Anyways, I'm pretty sure the 335i makes a lot more than 260lbft, as even the 335i makes 300lbft, if I remember correctly, it's close to 400lbft, while hp is around 250.
Dave, I saw those curves of the VQ too, and they are indeed quite flat, however, the DE engines have a lower rpm than a J-series in general, thus, while the J-series is making less torque throughout, it's making that torque "longer," thus contributing to the higher peak whp.
I have no doubt that the VQ has high potential, but back on the OP, I think the Maxima mentioned only had a intake, and I believe that intake on VQ actually hurts output (or is it only for G35?), I'd imagine 200whp for the mentioned Maxima won't be too far off, as opposed to 220whp-230whp TL-S 5AT. Assuming 225whp for the TL-S, that would be roughly 16lb/hp, as compared to 16.3lb/hp of the 4AT Max. That's pretty much negligible, but the TL does have one more gear ratio, and the AT on 2007+TL has been tuned more aggressively than before. So, like I've said in the 2nd post, it's gonna be a close race.
TwinTurbo335, G37 is too heavy, there's not much low end torque (tuned to produce max hp of 330). Why don't you trade in your 335i sedan for a 335i coupe?

1) The coupe rides on the same chassis as the sedan. They share the same wheelbase.
2) Due to stringent crash regs, the coupe needs a lot of reinforcement in the structuture to contend with the large door opening. Nissan admits this is where most of the weight gain comes from.
3) Most coupes are shod with large 13" rotors and large 19" rims/tires.
This week the rumors were confirmed that the G37 sedan will arrive next year as will the 370Z (same body style for now). The G37 sedan will flat out move. Seeing that people are getting 13.6-13.8@102mph out of stock G35 sedans (regardless of tranny), I fully expect the 330hp G37 sedan will see 13.4-13.5@104mph which puts it in the same league as the 335i and IS350. Bolt-on slicks and you're looking at 13.1s or so. Better yet, you should be able to pick up a "base" G37 sedan Sport with 18s, 13" rotors, leather, LSD, HIDs, and 6MT for around $36K.
If you have your heart set on a coupe and have $46K to spend, I'd be at the BMW dealer. Honestly, if I had $43K to spend, I'd be at the BMW dealer too getting a 335i sedan. It's still one of my favorites.

Dave: I always wanted a 6mt car. but coming from a fwd to a rwd, makes me never want to get another fwd again in my life. Still nothing is easier to mod than a 335i. A $1000 mod will get you in the 12s. I feel like swapping someone's lease on a coupe. Going to think about it first.

One concern I have with the I6TT is how well it can last under increased boost, The engine already has some pretty bad heat soak issues, even on the ones with the "fix".

I just heard thats a issue for the 2007 early batch of the 335s. the newer one does have any problem.
what about the g35 sedan 6mt? what do you think about that? its way cheaper than the g37 * thank god * and its cheaper than the is350. going to lease one for just 2 years.

This thread has gone too far and I'll be the first to predict the most likely outcome:
It will be a close race.....until the Maxima driver takes one glance at his car's interior and projectile vomits all over his lap, steering wheel and gas pedal, thus causing his foot to slip off it. He will run roughly 17 flat at 80mph and the TL will prevail with class.
