That add's some spice to it i wonder what the speeds are going to be anyone have a rough guess?

Ludicrous speed

My guess:

Cars without KERS: 350km/h
Cars with KERS: 355-360km/h

With regard to KERS:

On the outlap, the only place that KERS will gain you an advantage is any point where you do not have to brake before the start/finish line, because as soon as you brake, you are taking away the energy that KERS has put in: If you use KERS and then brake before hitting the line, you wont carry any extra energy into the flying lap than as if you didn't use KERS.

However, once you're on the flying lap, you can use KERS anywhere you want, not necessarily only as soon as you pass the start-line.

Would that suggest that we will see it being used on the exit of the parabolica, and then wherever it is most efficient to use it thereafter?

----

Where would KERS get used on the flying lap? Would it be on the exit of the slowest points? If so, would that suggest it would be split between the exits of the two chicanes?

----

edit: Also, with regards to people thinking that kers will cause the cars to hit their rev-limiters: Do you think they would just gear 7th slightly longer, allowing for increased top speed with KERS? What are the benefits/losses with doing this?

they can store Kers worth of 2 laps in one recharge in braking zone
so they can double boost in S/F straight

They've gone to plaid!

What I tried to get across is that although they could double boost in the S/F straight, that's not necessarily what they will do... If it is more efficient to use KERS somewhere else, they will.

Just a Kers thing.. It is not "linked" to the brakes directly. It is directly connected to the crankshaft. It would seem an obvious step that to charge it they leech some power from the crank when under braking. If they wanted to charge it up for an outlap then they should be able to do it directly from the engine without an application of the brakes. The motor would labour a touch but why not?

Does that make sense?

Ref the specific point of double use - it is a no brainer to give it the full 6secs out of Parabolica and up into the main straight and then use the next set of 6.6s as soon as they are not traction limited onto the curva grande and out of lesmo 2.

We'll soon see anyways!

the rule specifically says the kers shud only be charged using rear wheels , nothing else.

[CMSMJ1]

I know this..but the unit is at the front of the engine and so technically is being charged by the motor rather than the wheels.
Is it only allowed to charge under deceleration?

[ESPImperium]

This is what im envisaging for KERS Deployment for Monza:

Yellow = KERS Deployment
Aqua = KERS Recharge Zones



I think they will deploy KERS out of Parabolica and once over the start finish line, when the system gets refreshed, they will deploy then, hence double deployment.

I think the best place for non-KERS cars to pass KERS cars is from the exit of Varianti Ascari down to the Parabolica, as the KERS guys wont want to use it there as it will hamper them down the main straight.

AFAIK the kers motor is behind the engine [correct me if i am wrong]
and its only allowed 2 b charged during braking

Yes the unit is charged via the engine - but it would be detrimental to straight-line performance to charge it during acceleration. I think the regulations only allow braking anyway...

This is possible KERS deployment zones?
Otherwise full throttle time out of Parabolica lasts about 15 seconds and there's no way they can use KERS all that time even using is twice.

Thats why they will try and save as much as they can of their 6.6 seconds for this area. Posibly only use a little out of Retifilo, but mainly they will use it out of Paribolica and just after the start line, abouot 3 seconds each time, with about .6 of a second out of Retifilo.

But if used spairingly thruout the lap, i could see more gains than just the high speed secions in Quali. They will change to use the KERS systems in the high speed zones in the ract tho.
