In previous Races, Qualifying or FPs...I've heard Alonso's engineer refer to a gas gauge. I don't think it's on the steering wheel. I think it reports back internally to the engineer. I wonder if that was malfunctioning and had them concerned.

Why not? The wheels are driving the crankshaft on lift off. The crank is rotating the pistons and the pistons are pumping air at 10,000 RPM out of the exhaust manifold. There's some energy in that which would cause the turbine to spin. If the turbine is spinning, there's energy to take from it.

I know some superchargers require 60 hp to spin @ 12K rpm and generate 10 psi of boost. I'm sure the MGU-H would require around that. if you take any car or Turbo charged car like a RS5, there is a ton of back(reverse) pressure when they come off the throttle.AR3-GP wrote: ↑20 Jun 2023, 23:28Why not?

Hot blowing was burning fuel to generate hot exhaust gases while off throttle.Zynerji wrote: ↑21 Jun 2023, 00:09Ooh! Hot blowing?AR3-GP wrote: ↑20 Jun 2023, 23:28Why not?

The wheel are 'rotating the crankshaft and not driving it on lift off. And, the crank is 'moving the pistons up and down' and not rotating them.
The formula 1 turbocharged ICE will have no 'ton/s of back (reverse) pressure in the exhaust system when they come off the throttle, because intake to pistons will be totally shut-off. And when the intake to pistons is totally shut-off (throttle lift means throttles closed) fuel to engine (fueling) is also shut-off, So the exhaust system is not only 'cold' and not 'hot' blowing, but blowing at i's weakest of pressures. Cold and at its weakest exhaust pressure is useless for the turbine to do any useful work.diffuser wrote: ↑21 Jun 2023, 00:23I know some superchargers require 60 hp to spin @ 12K rpm and generate 10 psi of boost.

Are you suggesting the Mercedes engine people assigned to AM would communicate AM engine data to the Mercedes team during the race? That would be blatant cheating.
No. That has nothing to do with the chassis constructor in Brackley. The engine constructor in Brixworth is a separate entity that provides embedded engine technicians at each customer team.
Which would spin the turbo, and allow off throttle MGUH regeneration.diffuser wrote: ↑21 Jun 2023, 00:26Hot blowing was burning fuel to generate hot exhaust gases while off throttle.Zynerji wrote: ↑21 Jun 2023, 00:09Ooh! Hot blowing?AR3-GP wrote: ↑20 Jun 2023, 23:28

While 'hot' blowing was burning fuel, 'cold' blowing was not. They both were used before the hybrid era, because at that time there were no rules re ICE throttles and throttle pedal relationship. Those two modes of blowing the diffuser are not possible nowadays, and neither 'off-throttle' cold blowing of turbine, this as when driver goes off-throttle, ICE intake throttles are ditto-closed. and when cylinders cannot breath, cylinders cannot pump-out into exhaust. meaning the turbine is as good as useless in so much as generating any energy.
IMHO problem with Lance is, apart from RBR who is on a different league, all the rest of the grid is as close as ever, so even a normal gap between teammates about 3-4 tenths put Lance a lot of positions down Alonso when traditionally, that gap only meant few positions differenceKimiRai wrote: ↑20 Jun 2023, 10:53If Australia this year doesn't count then it would be Qatar 2021.
It's likely they haven't fully optimised the car yet as Krack says after the upgrades.peewon wrote: ↑19 Jun 2023, 21:33Ive noticed the car being a looser on the rear end as shown by Lance spinning and Fernando with that uncharacteristic wall hit. Compare to the start of the season when it looked absolutely planted when Stroll drover around the outside on Sainz at the hairpin in Jeddah.
We need Lance to have more consistent weekends, I hope it starts from Austria. Wish I'd know what is the problem if there is any. No one is asking for him to beat Fernando but he needs to be in decent points scoring positions at least. He's not as bad as his last races would say, so I trust he needs to get into a good rhythm.
there is a lot of energy in the turbo and MGU-H rotating at c.120000 rpmsaviour stivala wrote: ↑21 Jun 2023, 06:07While 'hot' blowing was burning fuel, 'cold' blowing was not.
