The great transmsion debate.

2 I have a 2700 rpm GTM torque converter big difference over stock
3. I have a Moterdyne intake madifold
4 My car with me in it is 3372 lbs.
5. I have every bolts on that there is
6. I ram more air into my stillen G3 intake.
7. it also has skinney front tires, 305 35 18 drag radials and 2 piece racing brake rotors
8. there is no passenger seat in the car.
9. i have a racing seat but no seatbelts for it yet car will then be 3350 lbs.
10. i run a very agressive Cobb map in the car on 94 octane + lucas octane booster
11. the timing has been advanced by 2 degress.
12. I also now how to launch my car and shift it in the MM and not redline it or hit the limiter 8100 rpm.
13. the line lock is being installed and i need new back brake pads so that i can launch at 2800 to 3000 rpm.
14. I now am swithcing to the uprev where i can ajust the line preasure in the tranney
12.42 is a very fast time. The only car that is quicker is J nauts 6 mt. I can a sure you that his car is very light and has more mods, and power than mine.
If you look at the 1/4 mile formulas you will see that it take 347.5 RWHP to run a 3372 lb car down the 1/4 mile in 12.42.
My best dyno pull was 322 rwhp.
Im almost 1/2 second faster than the next closet 7 AT. except fot J's car there is not a 6 MT close to mine.
When I get my GTM
VB it will shift a lot quicker. The only bad delay is 4th to 5th it take's 0.68 seconds compared to the 0.31 shift time of the other gears. Just reducing the shift time in 5th to .48 will put me at 12.28. with GTM's fulley built 7 AT (coming soon ) i can see a my car running 12.0 to 12.1's.
I also trap at 114.37 mph.
If it improves the other gear shift times it will even have a lower time.
My bone stock time is 13.201.
Its not fair to compare my car and J nauts car to other 370 's.
they are both done to the 9's.
When you drag race the weather has a lot to do with your times
a really hot night and you will slow down.
There is a down fall to the 7 AT. if your driving at 60mph and you floor it . It take's forever for it to drop a gear an boggey.
I also own a 2003 5 AT 350 z with a stillen SC pushing 10.5 lbs boost.with high speed stall and a
VB in it with 3.353 gears. up to 60 mph the car is really quick.
both cars have the same problem at 60 mph, floor it and nothing happens. There had been no improvment in either tranny.
The 7 AT shifts fster than the 5 AT.
the 350z is about to become a really fast car as i have a GTM 4.2 stroker with a wolf 850 ttbb for it coupled to a speed force built 5 AT.
Getting back to the debate. I can tell you that nothing takes my 370z off the line. It lightning quick.
Im going to the track this monday and hopefully it will go faster.
If you let me drive a stock 7 AT and run a stock 6 MT i will beat it in the 1/4 mile .
the whole secret is knowing your car no mater what tranney is in it.
J naut has a really fast car, just look what the closest 6 MT is to his time. he has done his home work and his time slip proves it.
