I agree.
I know the supra boys go to great lengths (i.e. 29.5in tall tire) to stay in 5th in the mile.
I'd recommend along the same lines....3.3FD, 8000rpm, and a taller tire.
A 28in tire in 5th at 8k rpm and the 3.3fd is 202mph.
I just don't think that an overdrive gear is gonna like that stress for that long.
GL though, let us know how it goes.

Lol.... XKR checking in...
I agree with what most are saying.... Whp, gears and aero is the key. Going 200mph can be done in most any car with the right setup.... It's going 200 in a mile that crazy hard.
None of the super cars ( lambo, PC-GT, Kona) can do it without the help of some serous power add ons....I have tried it.... 180+ is not hard.... But 20 mph seems like impossible to make. This was done with 800whp DJ.
I have done 188 + in the G.... It's not stable at those speeds ...and it took way more than a mile to get to that speed. I have hit the 200mph in a mile driving a friends Ford GT TT... This is my reason for my other build.... And still there is a chance it may fall short. I am not into the Supra thing... building a car I can't drive in traffic.....200 in a mile is not important to me ....YET
... But making 200mph period is.
OP......you will need some serious Aero work.... Under body mostly or the car will lift or float.... Not a nice feeling right Alberto It has happen to me in my G....Traction of course.... And way more than 600 whp... Remember.... If you had more than 2 mile to hit 200.... Then you have enough.... But in a mile.... Power is 70% of this puzzle.
Good luck

What some will find hard to believe is that the car went faster 191. The timing equip they had at the event fell short and read bad numbers across the board all day. Everyone at the event was scrambling to get gps's to read mph. Mike was able to run 197 via gps. There were several cars able to break 200.

Hal...have you looked into swapping in a Ford 8.8" from an IRS 2003-2004 Mustang Cobra? That'll give you the ability to choose from all sorts of gear ratios.
I am with you on the 6th gear. You don't want to be putting full load into 6th gear, or an overdrive gear for that matter.

I agree,
I am bone stock aero on my 04 Gc. I get to 180mph in a hurry. Never really pushed it further than that.
However I did find the limits of the stock G front clip!!!!!!!!
I think folks really need to head the rpm levels that SP and Injected are playing with (don't forget you are gonna need a big girdle for those rpm's).
Remember SP went 160mph in 4th gear on a 3.5FD, and 28in tire.
Thats 207mph at 8700rpm in 5th gear (capable).....imagine how much speed you don't lose by saving a shift at 160+mph?????

There is nothing that is a "bolt in" for those gears.
Now I'm sure there are places that will be more than happy to cut your whatever gear you need.......for the right price of course lol

Mike...... I was talking to JOsh the other week, and he was telling about you guys going to the next milemarker-1.com event. Sounds like a good time! I hope you can accompish your goals!
Question for you though....... you stated you Hp and TQ numbers back on the 1st page. I noticed that the torque was a little higher than the HP.....that's usually an idicator that you aren't making peak power much higher than about 6000 rpms (since HP is a mathematical derivative of Torque and RPM). You also stated that you will need to rev out 6th gear to close to 7500 rpms. It would seem to me that you are going to to be well past your optimal power band while going for 200. You might want to look into some taller race tires if you can't get a taller (lower numercial) gear set.

6th gear has really small teeth compared to 5th gear in the 350Z/G35 transmission. Here is a picture of it. 5th gear is the one on the end of the shaft in this picture. 6th gear is the one with the finer teeth to the left of 5th gear (also on the shaft). The other gears I am holding are from other cars just for comparison purposes.

Makes sense. OD gears (6th in our case, believe it .794:1) are not meant to be "pulling gears". They are inteaded for mileage...hence in most tranny's they are physically smaller.....and the oiling is generally not as good cause they are not expected to be dealing with high-heat that is associated with high load....you are just "supposed" to cruise at a speed in that gear not accel.

Is it larger diameter gear/carrier or thicker.
Thicker is better. On that point, the Auto 3.3FD carrier is a touch thicker than the 6spd 3.5FD

I wasn't referring to swapping the gearset from one pumpking to the other. Hell you can't swap from the auto 3.3FD gearset to the 6spd 3.5FD (gotta swap the whole pumpkin).
What I meant was are the gears thicker/stronger in the 230 vs the 200 or are they just a larger diameter?

The R230 is a 230mm ring gear, R200 a 200mm ring gear (diameter).
The R230 in the 300ZX never breaks, I've seriously never heard of a broken one, given that the R200 in the Z never breaks either, I think it's safe to assume that the R230 in the Armada is stronger as well.
