[QUOTE=Funner567]"gthirty" leave it in "D" and let it do its work it will not redline the car in "D". it will automatically upshift for you. Its fine if it reaches right before redline or the first tick of redline cause in "D" the computer does the shifting at the correct moment itself, thats why for racing many people perfer leaving the car in "D" in Automatic cars. Now in manumatic, the car can go past redline and hit the revlimiter and stay there until the fuel shuts off. In manumatic mode the computer will not upshift for you once you reach the red-line area so be careful, you have to upshift yourself. You get me? [/QU
Thank you very much. That was very helpful and you just made a lot of things clear for me. I appreciate all the help and info you guys have given me. Thanx again.

 

by your logic i shouldn't have headers or cams in this car

mine doesn't shift into next gear, it just sits there bouncing off of it

 

I've had the a loaner on the freeway in manu-mode 2nd gear. It is actually pretty damn smooth after you hit the limiter. If you continue to floor it while holding the gear, it almost maintains the rpms bouncing between 7K and 6.8-6.9K (in the red!). Of course, the gearing has a lot to do with this... you bounce off the 1st or 2nd in a 6mt and you're going to feel it a lot more than in manu-mode 5AT.

The limiters are there to protect the engine from accidental over-reving. Not foolproof, and by no means not a good practice in terms of driving. Practice to shift just before the rev limiter, if you hit it, you're loosing power and momentum. Better yet, get a dyno and shift at the peak points with the most power from one gear to the next.

 

A lot of talent it takes to smash the gas pedal...whatever--waste of money imo--I'd take a bone stock 6 m/t over your lightly modded slush box any day of the week buddy...

 

go for it


my old pi stallion 2800torque converter + 4.10 gearing + valve body shift kit on the hardest setting would rape your pos m/t from here to sundown in every gear

 

Calm down cockboy--no need to mention rape--I though Canadians were supposed to be polite. Anyways--like I said, what a waste of money to have to go through all that to get the performance and "feeling" of a manual.
Sorry, but unless you have a DSG, your automatic will always have smaller ballz than a comparable m/t--you have no streed cred..I feel sorry for you..really..

 

a built auto will smoke a manual 6ways-til-sundown. There's a reason sub 10second cars arn't manuals usually, heh

 

Ok, a "built auto" v. a 6 m/t not a stock auto v. a stock 6m/t. How about a "built auto" v. a "built 6 m/t" would an auto still smoke the manual? No.

Yea, like I said DSG autos (sub 10 sec. cars) are fast and supposedly can shift faster than a human can. BUT, the G35 is NOT one of those cars. Sorry buddy, but you don't own a DSG, you don't own a porsche, you don't own a car w/ paddle shifts, YOU DON'T OWN A RACECAR, You own a luxury coupe w/ "manumatic" that you've poured lots of money so don't front like you have anything better.

Like I said, you have no street cred. Have fun w/ ur auto. But all things aside, I am really just busting your ballz. I used to drive auto's before I learned the enjoyment of manuals...

 

btw, i also have a 911, so your staement isn't all that accurate

btw, have you ever even driven an auto with a high stall tq converter and valve body upgrae?

 

My car tends to hit redline really quick too, I'm not sure why

Check out the KPtechnologies shift light, they work great for autos and manauls and are much more visable (yet still stealth) then the stock 'shift' indicator. You can program them to blink X rpm before redline to give you a chance to shift before you hit the rev limiter.

 

a lot of cars on here are Auto and have INSANE mods including turbos, TT's, S/C's etc and are faster than a lot of manuals as well. some people by autos for different reasons. also keep in mind a lot of people arent that great at shifting. an auto will shift perfectly everytime whereas a stick can have driver error. the Z i had was an auto and i spanked M3s and porsches all the time on the highway. our trannies have been known to be pretty good autos. just playing devils advocate here not taking sides

 

Good point papagaz. Many people buy an auto for different reasons: but who buys an auto g35 to "race" when a 6m/t is available? Also no matter how good the tranny, I'll never trust a computer to shift for me unless it is a DSG.

 

then good thing you got the 6MT

 

I agree. How can anyone trust a little black box that can only run 20 million calculations per second and has direct access to every vital engine parameter to shift the transmission at precisely the right time?

A properly setup auto tranny will elimnate one area of driver error. Also, when you get in to high power cars they rev so fast that you can't physically shift the gears fast enough when going down the track (like in my car). An auto tranny would probably help me more then it would hurt me, and I don't consider my car high powered (~500whp).

Its great to have opinions, but take a second and research some of the newer computer controlled trannys and how they act when they are built for drag racing!

PCNA claims that the 997S turbo with an auto tranny will accelerate from 0 - 62 in 3.4 secs wheras the manual will require 3.9 secs. This despite the fact that the auto adds 100 lbs to the turbo's curb weight. Porsche claims that the auto better optimizes its Variable Turbo Geometry feature which allows the turbos to spool more quickly under hard acceleration. Hell, I prefer manual trannies too, but if autos are faster, I'll be buying them.
