Post: [Help] Transmission for Modded Cars
03-04-2013, 12:23 PM #1
(adsbygoogle = window.adsbygoogle || []).push({}); I'm messing around with them In-game, but as Vectriixx said, the transmission must be modded for it to work at high speeds.
Must this also be done in the HxD? Or can it be achieved In-game? If so, which way do i mode the pointers xD

It really suprises me how many people that are modding Gran Turismo don't know how a car works. Or levers.

Editing the Transmission in HxD, even if you found a way, wouldn't do anything different than changing it in-game, unless you changed the physics on the game data.

Research Gear Ratios, that should tell you everything you need. At some extreme point, more power n the same transmission will actually reduce top speed, but this isn't something relating to hacks, this is just normal driving physics in real life.

these things are very true however this morning i got my black edition to go 999+mph on SSX on the 6 speed tranny. all im saying is that sometimes you can get lucky Happy

Are you fucking retarded?

I'm sorry I lost you when you hit the reply to thread button, what are you getting on about I am seriously confused and it hurts.

HxD has the find/search tool for a reason. If you search the right thing with the right settings you'll find what you need.

Read up. Unless you can hack the game data and alter physics, not just save data, you'll need to work within the framework of 'real life' in GT5 to produce high speeds. There is a reason high speed land vehicles use thrust (rocket propulsion) instead of wheels.

To give you a starting point, those graph numbers for HP and torque in the tuning screen? Those mean how much power is being produced by the engine in your car before the transmission and wheels. That torque is multiplied by the gear ratios, giving either more torque over less distance (higher acceleration, lower speed at a given RPM) or less torque over more distance (less acceleration, higher speed at a given RPM) The trick (and its not hard) is to find the happy middle where the torque is not so great that it spins the wheels and wastes power (every bit of tire smoke is lost speed) but it sufficiently high enough it can overcome insane air resistance.

Lastly, if the body of the car doesn't produce downforce at high speeds, the wheels won't grip the road as well, and you'll get less torque (thus less acceleration and speed) to the road.

It's not like torque calculation and gear ratios are complicated, its just that I'm surprised that people who can see a wall of hex code and figure out individual values through intuition and trial and error, complain and don't seem to understand basic driving physics, stuff you can easily figure out by just playing the game (or taking your own car around the block).

EDIT: I will concede that the in-game transmission may not allow ratios high enough to read extreme speeds for cars under, say, 10000HP, but I doubt this is so. While more power doesn't always mean more top speed, it can if everything else is made as best as possible. Since it's obviously possible to get 999 mph, then this should work without you having to tear apart the save file and adjust the way the game models air resistance.






tl:dr: remember you're playing a DRIVING SIMULATOR. No matter what Frankenstein mods you do in your "garage" when your car is on the track, it has to work within the game's physics, at least until someone manages to hack the disc or game data and modify them.

Or just import the Redbull transmission data Not Happy or Sad"

See, you make a statement like "It really suprises me how many people that are modding Gran Turismo don't know how a car works. Or levers.". Essentially bashing the whole community and then you elaborate by giving a bogus fact about power reducing top speed. Then, you tell US to spend our time researching a fact you just made up!

When you get called out on it you give an explanation of torque, which by the way has nothing to do with you claim of, "more power n the same transmission will actually reduce top speed, but this isn't something relating to hacks, this is just normal driving physics in real life."

You start off your second post with listing completely bogus sources that anyone could sign up and edit. Then telling us to, "read up." saying we have to "hack the game data and alter physics" in order to "to produce high speeds." As if Wikipedia stated it.

You then burst into a three paragraph explanation of reading our cars power on GT5, down force, then finishing up with an edit about reaching 999mph being easy when just 4 paragraphs you say we cant reach "high speeds" without editing the physics.

tldr: Your dumb.

Maybe I took a while to say it, but all I am saying is that there are extremely basic vehicle physics that answer people's questions (what I've said is accepted and understood universally as true, if you think its wrong, its because you haven't tried to experiment with it yourself, trust me, just try it) that are being completely ignored by otherwise intelligent people. That surprises me. Wouldn't it you?

I don't need to prove why more power can reduce top speed for a given transmission, thousands of others have done it for me in the last 100 years. Its mechanical grip.
