On throttle differential on start

On throttle differential is just how much the 2 rear wheels are allowed to spin at different speeds. This does not depend on whether the car is in a corner or on a straight. Its mostly in traction zones, which the start is also one of. But overall 65% diff for the start is a good number and then you reduce it after the start.

@DaanRzThanks for your reply but technically a differential (hence the name) makes the inner and outer wheel rotate a different speed to compensate in a corner, not on straight where power is distributed equally on both wheels.

People spinning out at the start do so due to turning while accelerating, so a differential change to reduce the chance of this can help.

When you get wheelspin on a start, of course the rear wheel speeds can still get out of sync. More diff will still mitigate that. Of course, the ideal scenario at the start is to not get much wheelspin at all, in which case of course the diff shouldn't make much difference if your steering wheel is straight, but that's a rare and perfect scenario, or a bogged down start.

Very welcome 🙂

Differentials allow the wheels to rotate at slightly different rates while cornering.

On a straight (or corner), under heavy acceleration (with some wheelspin) each side will have a different amount of grip and the side with less grip might just spin up really fast while the other maintains traction but does not get much torque.

A limited slip differential will limit the one sided wheelspin and provide more torque to the wheel with more grip. 

The operational parameters of the differential are important in corners, on straights, while accelerating/decelerating etc.

I recommend researching this yourself as how a differential works is fascinating from a racing/engineering perspective.

Hmmm not a bad reply from  @EA_Barry  maybe I was harsh in just dismissing you as imposter @BarryBL …… 😜😁

I know I know 

but 

im playing I’m playing please take my comical awesomeness as me just being friendly😍

Ask @BarryBL  we are bff’s😍

Just woke up and thought this would be one of those topics. Turns out @EA_Barry just cleaned the whole house 😂

It is one of those things we should recheck for risk of practically creating a metonymy for ourselves, mixing up cause and effect.

Differentials were made to allow the wheels to spin at different rates, as the alternative would be a solid axle with a single turning rate forcing one wheel to spin in place or to drag behind when maintaining the same wheel speed is not possible.

The main use case is cornering, yes, but it's actually whenever the spinning rates differ.

Kevin Magnussen released a book after being booted out of the F1 circus, don't know if it's available in English already but the media picked it up. There's a part where he goes like whatever, I'm not coming back to F1 anyway, so here's my race start procedure - and he goes on to mention how he would always open his differential and how he found it odd that people didn't talk about it that much.
