They decided to go long tube headers to reduce heat going back to the cylinders it seems.

The airbox is a monster. I have no idea what is underneath.

So I think the compressor is still at the rear of the engine... and that silver duct is going 'forward' not backward, either for a Merc like w-a intercooler or for the intake plenum

Agree. It wouldn't make sense to run your cooled charged air into the rear of the air box.

Does anyone have some info/updates on engine vibrations? Were they fixed during today's testing or do they still can't turn up the engine to full power for the most part?

Ferrari statement said nothing is wrong with the power unit.

Of course they did. They always do. Everyone does.

McLaren minor coolant leak. Remember?

Well once they switched PU's they started racking up more laps than before

telemetry from Haas F1 team:

Can someone analyze?

V-ERS-BATT 380V So it's the more less classic 400V system...

Seems that teams can and do carry more than 100kg on runs, sneaky, also wastegate target?...Interesting, I'm sure Ferrari is gonna have a field day with Haas.

Thats been the case from the start. They are only allowed 100 kg for the race, but they send the car out before the race to do a couple of laps including the formation lap, which they carry additional fuel for.

this is from in garage warm up..... pressure and temperature controls

Water based intercooler then.

Variable trumpets confirmed.

135 bar fuel. (could be just start up pressure though).
96*C fuel? What?

Yeah I was going to say, the air box is so big because of the variable trumpets. You need to build up pressure inside the box to take advantage of the increased torque from the variable length intakes.

TFuelRailGDI = 96.7
TFuelRailGDI 1= 46.1
TFuelRailGDI 2= 96.7
Not surprisingly, they are running heated fuel (as did Honda in the RA168e). This system looks even smarter. Seems they have two fuel supplies - one at the max temp they need (TFuelRailGDI 2) and one near ambient (TFuelRailGDI 1). By varying the mix they can inject at any desired fuel temperature (TFuelRailGDI ) in between, and change the temperature - almost instantly.
