Ok back to Transmissions

[[XR](\/)power]

Someone started a topic about transmissions, which now ended with Chey being an angel and walking while flying or something, not like it really matters anyway we all knew that :). My question is:"Is there need for low speed or close trannys??". I've only now started to see some of the differences, which are minimal to say the least. Since the game started it was always high speed tranny for me and nothing else.

So I guess this question would be adressed to some of the veterans of the game, or ppl who have played it more than me :) to shed some light on this matter...this is ofcourse not including race versions...

welll.. i have also always used hi speed.. except in 73 RS, i use close ratio coz its faster......

L.ZD, a fast racer who lives near me. once told me that the low speed gear box is quicker.. hes probably right, but I never raced on Cote much especially in 95.. that seems to hate me.. all I have ever done is 2:00.75.. which is 3 sec slower than RJ_prizes great 1:57.90...

I imagine once you get within a second of the world records then you better start checking to make sure your transmision is correct, otherwise I think the high speed tranny is usually fine. :) Just my thoughts..

[Cheyenne]

Yes, Josh is exactly correct.

The low speed trans will make you faster, but only just a tiny bit on low speed tracks (cote, corsica). In generaly, unless you are really very, very practiced sticking with the high speed transmission will actually be faster because you will know when to shift by feel. Switching to the low speed trans can throw your timing off. Same with close ratio. If you're looking for that last ounce of speed, use the slowest transmission you can without hiting top speed (in which case, go to the high speed trans).

That's the best advice I know how to give on this. I know both L.Q and ZD have explained it to me in these terms and showed me firsthand how it is effective. -^

I have found that on a few tracks (Corsica and Pyrenees come to mind) I get better times with a close ratio or low speed transmission. Obviously, they do require lots more shifting. For this reason using an automatic/close ratio transmission often works well.

With the 73 RS (as Wazza said) and I believe the 65 and 67 911s the close ratio trans is quicker and has a higher top speed than the high speed trans.

[[SK]HiLL]

:D

IMHO the first thing one needs to consider is...What is the highest speed obtainable for any given car, track and direction combination?

OH...BTW!!
A manual trans is faster than using an automatic trans. The auto transmissions seem to upshift prematurely...losing valualble RPMs

EXAMPLE:

Corsica backwards with a 95T 993....the highest speed that you can reach is about 180 MPH...approximately.

High Speed: Max speed 197
Close Ratio: Max speed 187
Low Speed: Max speed 182

So, all 3 gearboxes have the ability to go faster than the track will support..(in this case)&(

The Low Speed gearbox is the fastest accelerating...the Close Ratio is 2nd, and the High Speed is the slowest accelerating.(with highest top end)

So, you want to pick a gearbox that has the FASTEST possible acceleration and the required overall top speed....

In this case it would be a Low Speed gearbox.

I consistently do sub 2:00.00s OFFLINE with a Low Speed gearbox in my 95 Turbo 993 on Corsica backwards...8)~

I hope the ramblings of this old man will be of some help to you...

Good luck with "The GREAT Tranny Debate"!!!

as jtace said , the box maybe cause only a second difference.
in my opinion , the different gear box is different of the gear ratio.
the car's engine is not change. so the car's power is the same, no matter the gear ratio changes.
so the choise of gear box is lie on the road's length between the turns.the shifting waste time, although just a little little.
assume there's a 100 metre straight, and you useing low box, the car's gear 4 come its top speed while it's in 80m of 100m, then you need shift up to gear5, and a little later you must break ,
shift down to gear 4 ,and turn. Oh, what a bother matter! In fact, you just choice the high box , is all ok ,the gear 4 go to its top speed while break point.
And if opposite ,the straight 's length is only 60m, then low box is perfect, because:
the engine speed is more high ,the accelerate is more fast.. so in the turn, like 95T in the cote 's last two right turn , low box or the high box is both in gear 6, but the low one has more accelerate, because the engine speed is faster than the high one.
except for the low and high ,the close and the standard box is useful. My team-mate RJ-xxx or HK pclive, always use standard box of 95T , except zone and bahn. he said standard is the best choise, hehe.
i think the other cars is in the same elements.

the accelerate matter, low>standard>close>high, is a say
,it's correct when in conditions.it's related engine speed,the rpm.

if speak to the 0-xxxkph(mph) accelerate, i can bet the high box would win.

Personally for all of my 93-02 cars I use a high speed gear box. With my 993 and 996 Turbos I constantly run about 3.4-.3.7 0-60 but I'm kinda dissapointed that like I only get 197MPH top speed out of the cars when I have wayyyyyyy over 600HP and I only am getting 197MPH tops, I wish they could do something about that.
Also wouldn't that be great if they had this thing to like tell you ure 0-60, 1/4, top speed, and breaking distances after u mod the cars?

[Cheyenne]

Hi, Prize!

Yes, I agree with all you say. The differences are minute/small and it does depend on where the "shift points" come. The faster accelerating low-speed tranmissions can be not as good if you have to shift say, right during a turn, affecting the stability of the car. Also, to some extent the driver can adjust how they drive to make up for deficiencies.

Hi, YAUNDERSTAND!wouldn't that be great if they had this thing to like tell you ure 0-60, 1/4, top speed, and breaking distances Yes, I agree completely. In a game like this we need to be able to see "telemetry" reports. Without that it's just kind of "seat of the pants" feel and since it's a computer game, we lack even that! &(

Hi, Prize & YAUNDERSTAND...

Hmm, I'm very "agreeable" today! :rolleyes:

[prize]

wish you agreeable every day , Cheyenne and all friends here ...

QUESTION:

You know how in POrsche Unleashed when you reach the top speed of your car say a 993 Turbo at like 197 MPH and then the car kind of hesitates and the RPM's drop and you loose some speed? Is that necessary, and does that happen on real cars? I wish the car would just stay at Max RPM and not slow me down when I'm goin as fast as I can.

ya, i want to know it too.
i guess.... i cant guess, never drive a real car.:mad:

[Cheyenne]

Well, yes, that happens in "real" cars but not quite that way, usually. Some cars cut the flow of fuel when the engine reaches maximum designed rpm, causing it to sort of "bog", much like the cars in NFS-Porsche. Other manufacturers use much more subtle means like cutting off the spark to a 1 or more cylinders to accomplish the same thing in a more gentle manner. Most race cars with high performance upgrades do it this latter way as fuel cut off types can cause a sudden temperature rise due to extremely lean fuel flow, causing engine damage. So, yes, real cars do have rev limiters.

Now, YAUNDERSTAND, is it necessary? Not really. in NFS Porsche you'll notice that the engine has the same maximum rpm stock as it does modified. Most modified cars are using parts of much greater strength and can have, generally, a higher rpm than a street car. Another way it's not necessary, is say you had a track like autobahn or zone industrialle in real life. Someone would manufacture a transmission with gearing that would allow the car to reach much higher speed without hitting the rev limiter - why would someone make that? Because everyone racing there would HAVE to own it because otherwise they would be guaranteed to lose the race.

[YAUNDERSTAND]

Thanks no one could've explained it better

[[XR]Moxi]

How about the transmission quick shifter? Does that have any effect at all, positively or negatively?

Thanks.

[Cheyenne]

The arguments I've heard go like this...

1) The quick shifter cuts the time it takes to shift the car more than 50%. It's well worth any other penalties it my have to be able to get back on "power" sooner.

2) The quick shifter doesn't shift fast enough to justify the weight it adds to the vehicle.

Personally, I go with argument #1. The problem with PU is there is no real way to tell whether something is faster if it's very incremental. There is no telemetry, so there is no way to genuinely analyze how the part affects the car other than feel. If you try and go by feel, then you can't rule out "inexperience" with the part. Without telemetry you can't rule out chance, driver error, driver success or dozens of other factors in evaluating a part. Only when the effect is very significant and you really make a more solid judgement. In my opinion the difference in using the quick shifter is minute. But, just going on "feel" and opinion, I much prefer to drive with it. 8)~

[jtace]

Chey summed it up rather nicely.. I dont' think we'll ever know if it really is of much help or not... :)

[Wazza]

mmm...
well.. i tried short gear on 95 on COrs bkw not too long ago.. maybe 2 months.. anyway.. i had that problem where I had to shift nearing the end of a straight, which was pointless because 0.5 sec later i was on the brakes!

I couldnt seem to get it faster. so now i will try racing Cote offline today with short and 80/0.. i will try to finally break the 2:00 mark..
and posisbly 1:59.. j/k :D

[D_Man]

I found the Quick Shifter quite detrimental to the 944 cars and quickly dumped it for them. On other cars the jury is still out, but I have removed it from all my cars now.
