It a bit small that intercooler rad? So they must be same arrangement on the other side?

I think all the renault engined cars have split the intercoolers into both sidepods. Merc too, but Ferrari appear to have the intercooler on one side.

[Blackout]

So twin scroll compressors for the Renault and Merc?

Is that a weight balance issue, assuming they are air to air intercoolers? Since the Ferrari is rumored to be air to water, the weight balance would be closer between the radiators.

[scarbs]

The intercoolers are very thick, about four times that of a water rad, so to have one huge intercooler will take up too much space for the ductwork to be efficienct. Twin scroll turbos are not allowed, the exhaust inlet\air outlets are siamesed before the turbo housing

[Blackout]

Does that mean the Renault V6 turbo pics are BS? their turbine has a dual entry (are we confounding twin scroll with dual entry?)

The 2 Pipes could still be merged internally before entering the turbine Area.

Wastegate on top of the turbo ?

I dont undestand what you mean exactly

[Holm86]

Wastegate on top of the turbo ?

Yes.

[Henning]

I would have thought the teams would prefer the air-to-air (if they are using it) cooler to be the higher and keep the air-to-water lower to help center of gravity.

Maybe it's a packaging issue (what isn't in modern F1?) and the extra pipes to mount the air-to-air cooler high, outweighs the center of gravity benefits.

Have I just answered my own observation?

[JDC123]

Wastegate on top of the turbo ?

Yes.

I didn't thing these turbo's had a wastegate, and instead the extra exhaust gas flow once the turbo had reached its maximum RPM was used to charge the ERS?

Renault said it is just a safety feature for transients and in case the mgu-h fails

Toro Rosso brings a new bodywork and steals one of my ideas again : P
Might act like a wing and rely on a lower pressure area for better air axtraction IMO
