Help on Drivetrain!

[DaDDyMELO]

When tuning AWD cars. The Drivetrain Torque split should be higher where? Front or Back?
Best solution for a torque split for an AWD car such as a ZZII?

Hi sir i think for this zz11 more high in the back like 30F 70R that what i have in my car .

Yeah I have 35 65. Works GREAT! I was just wondering

If you want a good tune for it with aero or not take alook of praiano's tune he have 3 tune 1 with aero online play and two with out aero 1 of them online :-).

No I have a great tune I was just wondering cause some one told me that he put more torque in front and I was a little freaked out by it.

Torque bias depends on your suspension and your overall preference. Generally I run 30/70 for a RWD-esque feel with front grip. A higher front bias generally creates understeer, while a higher rear bias creates oversteer. Some cars will require more bias in other places than others. It's up to you on how you want your car to feel, so there is no real specific place where the bias "should be."

 

[NEWDRIVER2]

Like Sir Robrabitman said its about your suspense some time so it can be 25/75 or 30/70 .

I won't advertise, but, my Winter Stars Tuning Garage won first and second in the Driver's championship last year in the Rolex Sports Car series, in GT class, and clinched the manufacturer's championship after 6 of 8 rounds. There was an Audi R8 on every podium of every race, and more often than not, BOTH R8s were on the podium.


We generally used between 40/60 and 30/70.


My rule is: 30/70 during qualifying, and 60/40 during a race. Also, the LSD can help you get the front to rotate, while controlling the rear at as much as 20/80.


I hope this was helpful. "Hanna" was a great car last season. I gave her a 15 hp bump, and now the tune's up on the Winter Stars Tuning Garage thread.

I'm looking to drag. But, it was helpful for races. Thanks

Woah, 50/50 works great for drag, IMO. Sorry, I didn't see anything for drag specifically. However, the 50/50 means that all four of the wheels are all working to give you as much forward propulsion as possible.


In real life, in order to run 50/50, you really have to beef up the transmission and drivetrain in the front of most AWD cars, but, we won't get into that for GT5.

For dragging, like previously stated, 50/50 is ideal.

No that's alright I should of specifically told what I was looking for but when I run 50/50 it doesn't feel as great as it was when it was 35/65

DaDDy can i ask you about you ride hight if its 35/65 i think your Front ride is more than the rear maybe like this let say F -15 R -25 correct me .

That's somewhat surprising, actually. I find that 50/50 AWD cars take off faster (at launch) than any other cars in the game. A Skyline R32 with a custom center diff can out accelerate a McLaren F1 up to 60 km/h, at least. Then, it depends how many times people upgrade the motor of the Skyline. I disapprove of adding more than 400, because the car isn't aerodynamic or efficient enough for much more than that, but, I must just say, the 627 hp BMW V12 is a good motor.

 

[robrabbitman]

That could depend on your transmission. If your gears are not right, you may bog down. Shortening the gear could fix this. Otherwise, you may need to start biasing torque to the rear until you get the fastest launch with the least amount of power lag.

Front lower than rear!

I actually have an amazing start.

I have no bog what so ever! Perfect launch most of the time

I suppose it could allow for more weight transfer to the rears. I stand by my theory, that, as long as you're at your ideal rpm's at launch, your car will do best with AWD 50/50, but I could be wrong. I've never tested it.

One day we should run. We can both test our theory's.

In the same car/tuning setups?

Same tranny tunes different torque split.

I'd be down for that.

Sure thing I'll be on tomorrow ! Need to go to bed its almost 3am over lol

I'm currently in Canada. It's 3 A.M. here too.

Wrong, in GT5 a torque split of 45/55 is the best choice for the most cars. Only a handful cars work better with 50/50.

Okay, we'll test that too.

Who can explain the R32 with a stock drivetrain its torque split is 150F I believe -50R its crazy makes me laugh every time.

Because it's not a 4G63 CT9A... Nissan's don't compare.

Changes from car to car but my rule of thumb for track tuning is that I only want the minimum amount of grip at the front to keep the back wheels from spinning at any point. This ensures the car remains planted under hard acceleration, but minimizes the understeer that comes with high front torque loads. I believe it also helps with front tire wear, the bane of 4wd setups in general. I've run 4wd cars in one series with a 15/85 split and in another with more power and harder tires at 30/70. The only time I'd use more front torque is on very high PP/HP cars with very low grip, but even then, only to the point where the rear tires stopped spinning under hard accleration.
