Default BPs in F1?

Woot! Proof that '90-'93s are better than '94s and up.

Technical changes for 2012 will include the use of biomass-derived fuels and tighter suspension regulations. The biggest changes, however, will come in 2013 with the introduction of a new engine formula (see related story), replacing the current 2.4 litre V8s with 1.6 litre four-cylinder units.

“Following dialogue with the engine manufacturers and experts in this field, the power units will be four cylinders, 1.6 litre with high pressure gasoline injection up to 500 bar.”

500 bar = 7,252 PSI.

Huh.


“An additional revision to the 2013 regulations will see a drop in the number of engines at drivers' disposal. Currently they can use eight units a season without penalty, but this will be limited to five in 2013 and reduced to four for subsequent seasons.”

So, 470 hp / litre, and they have to last for more than 1,000 miles each.

This will be interesting.

I don't mind too much about the 4 banger, we've been spoiled with V8s and V10s for the past couple years.

But I'm pissed that an F1 engine will be the same size as my Miata's, and only have 5,000 revs more. The 12,000 rev limit is way too low.

500 bar has to be a typo...

Probably about right. Current production direct injection passenger car engines with a mere 12~13.0:1 CR run 1500~3000psi. These F1 engines will likely be well above 18:1 CR.

The 12,000 rpm rev limit may be the end of the pneumatic valve systems too. I imagine the new engines will be more like current wrc units.

They should just be told: 5 engines a year, 1.6 liters, turbocharged, you have x gallons of y fuel. And let the teams do what they please. I think it'd be way more exciting this way. And why the focus on being enviro-friendly? I don't think I'll ever see F1 as a "green" sport. It exists so people can drive fast cars fast.

I'd kill for an old turbocharged quad-cam Ford Indycar.

It's actually nuttier than that -- they run 1800 bar, and 2000 bar (29,000 psi) is becoming the norm.

For commercial diesels, 2500 bar fuel systems are coming in 2012. That's 36,000 psi!

?!

Seriously, 36,000 psi is CNC waterjet territory. How the hell do you not carve a hole in the middle of the piston (or just blow the nozzle of the injector apart) with that?

The waterjet I ran at my old job was 50k and wouldn't do **** to aluminum without garnet, other than get everything around the tub very very wet.
