ok thank u, thats all i was looking for.
i know that it limits more than a 6spd. but i thought with the new engine and more power it wouldnt matter, i thought it would still take me no matter what

 

i think thats it.

2004 track vs 07 enthusiast AT

i think the weight has to do with it. isnt it true (what i heard) every 100lbs takes 10hp?

 

yeah listen to liljim he has no clue what he is talking about.

 

joe the auto's are a little lighter than the manuals but not by much.

 

i dont get it though, why would the nissan manual lie?

 

AND what i dont get.

if the 04 track model was nearly the heaviest, why would all of those videos reviewing and racing with the car choose it?

all the touge battles are with the track model and what-not.

AND NO I AM NOT HATING ON OTHER Z'S OF COURSE. i just dont think ur right about it being the heaviest. heavier than the touring and all. u guys go to edmunds about ur facts. just call nissan

 

joe they also use the same car for road course track times they do not just do drag racing times and also stopping distance and all of that and the brembos on the track gives it advantages and the suspension setup and light wheels. If they were using the car just for drag racing they might not pick the track model.

 

what you must understand joe is that you could of beat him for numerous of reasons. His car's engine might not be broken in yet that can make a big difference in speed. His auto has higher gearing than your 6 speed alot of different factors but its not just because his auto.

 

OMG! cars take oil?!!?!?!?!??! where does it go? in the cd player?

you toolbox, can you even read?

i already told you why an 07 auto will not fare so well. the HR engine has an advantage over the DE almost solely based on the fact that you can take it up to 7500rpms before you shift again. but only in the 6spd. in the auto, the 07 shifts at 6600rpms. so again, you are losing out on 900rpms worth of acceleration, right where this new engine makes it money, up top! how can that not make any sense to you. the auto on the 07 takes away a lot of power that the engine puts out.

if you have even driven an 07, you would understand that the car keeps pulling hard all the way to redline. i think if the rev limiter was bumped to 8000rpms it would still keep pulling.

now calm down, get in your car, put it in D and take a spin!

you don't like the hood, some people do. and the world keeps spinning............

Well either way its a Z and you can have fun with it either way. but my idea of a sports car in my hobbie which is road racing, ..a auto just doesnt cut it. But that doesnt mean u cant enjoy it and life goes on either way.

 

You cant go by those numbers, SAE came up with new standards when messuring HP for the 07s. Theres about a 25hp difference to the wheels on the 07 when dynoed compared to the previous years, and the torque on average is more to.

the average dyno numbers I see on an 07 from a dynojet are:

265hp
230tq


On a pre 07 I would say the most common is

240hp
222tq

If you want to go by this the 07 has 25 more hp and 8 more tq, to the wheels. Now this is by no means 100% accurate, as theres a lot of varibles involved, and I didnt take a proven average of the hp and tq for both cars. The right way to do it would be to take at least 25 samples of each car(pre 07 and 07) and find there averages on a dynojet.

The point I'm trying to make though, is that there is a bigger HP difference between pre 07 Z's an an 07 Z to the wheels, then you get by finding the difference of the numbers nissan put out. Also the torque on the 07 Z is at least the same or more then previous years.

 

whats more important then that is at what rpm is it putting down its power. The HR i believe puts down 80 percent its power at a lower rpm then both VQ35DE and VQ35DERs . When i had my old revup oil eating engine . Racing a HR which put 2-3 cars on me. Consistantly will pull on you because it makes its power sooner then u forget the hp differences, you can have 2 engines have the same output but ones tuned to output it sooner at a lower rpm then the next.

Just like the revup and the reg de

if you look at them all the revups 30% change did was make it more of a topend engine. Most of its power is higher the the reg DE. I knwo this because everytime i race a DE even when i had a reg DE at pocono. REvups would consitantly pull on me on the straights. But in the corners it was a great slug match. With them always coming uptop on the straights and the ability to keep themesleves in there power band more because of the increased rev limit.

Now with the HR it has best of both worlds. The lower TQ of the DE and the Top and of the revup with a revised plenum and duel intake system which gives it a great mix of both worlds. A HR would dominate both engines ona track in there stock form. Modded well anything goes when modded.

 

the reason the auto lost is probably car he didnt race you in manumatic mode... the car shifts around 300 rpm's earlier and at the beginning of the race hes probably sitting in like 3rd gear then the automatic will need downshift and you lose time there. try it again in manual mode and him redlining each gear. guarantee you different results.

 

Dude he was racing in tiptronic. The car would be a dog without it. I dont think anyone in ther right mind would not be using the manumagic mode on a course. If ya got it use it.

 

does he mention that somewhere? I didnt feel like reading through this entire thread.... i mean my auto went 13.7 with just intake and exhaust and its an 04... thats why i dont see why he should EASILY beat an 07. the only logical explanation is that he wasnt in manual mode.

 

dude, you realize a 07 does 13.3 right stock in a 6mt. And times are getting better. im out of this thread some people are just insane.IF you think a previous Z in a auto thats nearly stock is going to beat a new 07 HR Z man..wow....take the other pill man you guys are stuck in the matrix.

 

Rblover He Is Trying To Say That The Pre 07 Are Faster He Is Saying He Ran A 13.7 In His Auto So Why Would The 07 Loss To The 6 Speed.

 

what in gods name are you talking about? im stating that a 07 auto at worse should be a dead lock with a 04 track... saying that if my 04 went 13.7 the 07 should go faster... why are you completely flipping around what i said?

 

I Tried To Correct Him Bhk1004 Some People Lack Reading Comprehension SkillS Lol Jk. IM PRETTY SURE ALOT OF THE MEMBERS IN THEIR 6 SPEEDS HAVE NOT RUN 13.7 THEY JUST LIKE TALKING A WHOLE BUNCH.
