i have an '06 A/T, touring, non-rev engine, 6.5k redline, and i only said non-rev engine because i've read many posts on the forum that says '06 A/T are non-rev.

so, when i was on (P)park, i wanted to try to rev it to the max and see how it sounds, so i floored it, but i noticed that it just goes to the 7k and stays there screaming!! i was like . cuz usually in most of the cars when i floor it, it goes to begning of the redline and goes back and forth between 6.5k and 7k, gives a nice sound.. is that normal in my car? is that the reason why it's called a "non-rev" engine?

I want to know why my car does not do the back and forth on 6.5k - 7k rpm?
that's a vid of what i mean. http://www.youtube.com/watch?v=4NThfzuMGPg

another thing i've noticed is, when i'm on any gear, and floor it, it accelerates and rpm reaches 6k and i lift up my foot, it takes a second or 2 then it shifts to the next gear. is that normal? probably it has something to do with securing the gears?

actually, i did search but i couldn't find someone asked the same question, probably it's dumb, but tbh, i still don't know what means what.

Thnx in Advance

 

traditionally when we talk about rev or non rev up motors we talk about the difference between the 04 and 04.5. 04 had a non rev up motor (the redline is 6800 i believe.) 04.5 had the revup (7200 RPM redline). your 06 most definitly has the revup.

as for the gears, what you are describing is normal. it happens in all automatic cars and has something to do with the torque convertor. my Lexus IS300 does it too. It may be a function of the computer waiting for you to hammer the pedal again. if it bothers you that much, take your car to the dealer and trade it in for a 6MT or drive your car in manual mode.

 

'06 A/T = non-revup
'06 M/T = revup

 

i think that's most probably in most cars, yeah. so probably it's normal, but i want some more techy details on this.

thnx anyway.

but for the first part about reving up, i still didn't get it.. why it doesn't go back and forth between 6.5k -7k.??

 

Wow, seriously... . Rev-up motors = variable intake and exhaust cams with 7000 rpm redline. They came ONLY in 05 35th anniversary cars and 06 6mt cars!

OP you are right, your 06 auto does not have a rev-up motor. It does not bounce off the rev limiter because your ecu has a soft rev limiter that controls the throttle to limit rpm's. This kind of limiter is smoother than the "bouncy" kind as you describe that usually cut fuel to limit rpm's

BTW.. revving it that high without a load on the engine is pretty rough on it!

 

thnx..

1st, what's OP? secondly, i was just trying to see if it does that or not, i don't do that often, it was my first time today and i'm not gonna do it again..

thnx again for letting me know that this is normal stuff..

 

Try it without taking your foot off the gas. It took me a while to get used to that as well, but with the tip, you don't need to lift your foot off the gas when shifting gears. If you keep it on there it should shift faster for you, when I redline it and shift, it shifts instantly.

 

OP means original poster, as in the person who started the thread.

 

thnx again guys..

can anyone direct my to a link with more details about the non-rev engine?

thnx

 

You sure about this man?? Cause I have 04.5 M/T and I dont think its the rev-up motor cause it redlines at 6600 RPM.

 

again the only revup motors were the 05 35 anivers and the 06models thats all previous there was no Z with a revup motor in the US . There was actually a model called the S1 that was a model that had the revup 30% change aswell as more internal changes aswell but this was a extremely limited model.

 

+ 05 track model

 

its 05 anniv and 06 M/T

 

Is the 2007 MT a high-rev motor?
I was under the assumption that they had 7K+ redlines.

 

non-rev engines.. are we different?

Women that r spitters, women that are swallowers is there a differnece????

Rev up engine redline onthe tach 7000rpm's

non- reveup engine redline on the tach 6700 rpm's

different ecu settings, that I am aware of. I rarely get my Z to reline 6700rpm's, but I have the shift indicator light set to 4600 rpm's this is +/- 600 rpm's. Yes I have found the limits speedwise for more than 45 mins at 156 mph this is the speed that the Nissan engineers have set for the US based Z cars 2005 model enthusiast.

 

07s have 7.5k rev capabilites.

 

Its not know as a rev-up its an HR (high rev ) or whatever. Its an 80% different motor, than the prior VQ's .

 

What are some of the differences, & why does Nissan not denote the engine with a new designation not just VQ35DE???

 

VQ35hr and lots of info about it here https://my350z.com/forum/vq35hr-479/

 

okay UNCLE I give....What am I looking for??? This is 3 pages of recent posts, none seem to be telling me about the 80% engine internals and engine differences.

Most people who use a link within this site actually open the link then copy & paste the address from the correct post they are quoting, most of us are even smart enough to make sure that in our replies we check to see if the link we used is actually working. I suppose I could just take the time to read each of the 3 pages of posts hoping that I have enough time & patience to find your info.
