The thing is, a V8 Altima engine can run between 3,000 to 5,000km without major rebuild (except for valve gear updates), with few moving parts needing regular replacement. Kelly Racing back in the Holden days never usually laid a spanner on the engines, unless they were scheduled for maintenance, between rounds. Cheap performance, relatively.

A V6 biturbo engine is more highly stressed as a racing engine. Far more susceptible to temperature, inambient & oil and water and air. With vulnerability in inducting dirt and sand in the intakes. In having those 2 snails on there that are prone to falling out of balance, perhaps more especially in a variable boost environment we might see in the future. Data from the engines will probably need to be pored over, see where overboosting happened, temperature, and any other thing that could impact reliability

If you are 888 and throwing a fresh engine in for almost every event, the budget impost wont be a whole lot. If you are running the long life method like most other teams, the goalposts will shift.... in the hip pocket..

Of course. They could do worse than to mandate a Chevy LS7 crate engine for everyone, as trialled in NZ's V8 Supertourers.

Commercially, a problem I can see is the width of the space between the grille and the air mistake for the engine/brakes. Just like the FGX, this space is significantly smaller than the previous model... meaning less space for a commercial brand to land

Bet half that time was unpaid overtime knowing the industry.

Looks like a good product, hopefully aerodynamically superior to the current car to bridge the gap in that department.

Oddly, the bloke in charge of two of the slipperiest cars on the grid, designed the two iterations of the VF aero.

Always compromises when it comes to maintaining the styling of the brand so one optimised vehicle can trump another.

650hp for a 3.5 litre turbo motor (On E85 at that) is not stressed. It is not even close to being stressed. An R35 you can buy from your friendly Nissan dealer has near on 600hp and runs on petrol. Comes with a warranty too.

And overboost? Their biggest problem is likely to be turning the thing down far enough to get parity with the atmo motors.

How much longer can the VF be run? Is there a set date or its up in the air at the moment?
