what if that shortness of gear is in the power band...
what im trying to say is that i think a 350z with gears is more likely to be ahead that then without all the way to max speed

umm... i dont think im saying it right...
ok well...
think of it this way ima try to make a picture for ppl..
your racing righttttt.......
ok.. 4 gear ends say< 110-120ish.. 5th pullss. obivously harder
k.... well 5th gears just ends..
right when would shift into 6 with 4.08 gears say bout 140ish.
will the sixth gear drop into the Z powerband (mrev/spacer more like)
and keep pulling..
i've raced a mach 1 with 4.10 gears and he had me about 1-3 cars depending on how i drive, and about 135ish i slowly gain and then pulled by him because of his gears..
my question is: knowing that it will drop the rpm when shifting into 6th, will it continue to pull hard and strong givin that the powerband is where the 6th gear drops in...
i love the top end of this motor ad i dont wanna loose it because of gears

you really need to re-read this entire thread, because you're confusing yourself (and everyone else reading this 
)
as I've mentioned, it will accelerate 14% faster in every gear than it does with the stock ring and pinion
you love the top end of a Z? You must be driving a different car than any 06 Z I've ever been in...top end is not their strong suit, mid range is. The top end of a nearly stock Z is nothing impressive. The top end of a built Z is a totally different story

this is now the 3rd or 4th time I've said this 
the 4.083 final drive is 14% shorter than stock. As such, it will accelerate 14% quicker in EVERY gear, vs stock. It will also have a top speed 14% LOWER than stock, in every gear, and overall. I can't make it any clearer than that sorry

but if its 14% shorter like u say. than
6th will go therw the gear faster..
but slow down near the last rpm because its gear is shorter, and also the powerband dies down saldly..
have u actually tested this or are u just going by numbers and facts..
easier said ya kno.

First, 2nd and third gears are amazing. The car pulls sooo much harder now. I cant wait to get it to the track rental next friday. I have my ECU reflashed to the 7200 Rpm Redline.
Here is a break down of the STOCK gear ratio's
1st Gear Ratio: 3.794:1
2nd Gear Ratio: 2.324:1
3rd Gear Ratio: 1.624:1
4th Gear Ratio: 1.271:1
5th Gear Ratio: 1.000:1
6th Gear Ratio: 0.794:1
-Reverse Ratio: 3.446:1
This is calculated using 255/45/17 Tires

ah very nice...
this tells me nothing,,
i want knowledge of actually driving ..
no one can tell me unless they know..
say 06 4.o8 gears with a flash so it goes past 160, will
it pull harder,,,,,,,
past 140 and up or will i die.. its easy to say it will, than knowing
