Idea for V6 turbo configuration

[noname]

By the way, does anybody know if the are some liquid-cooled turbos out there?

The one which won Le Mans this year, to name just one.

And plenty others you can find under the bonnets of "regular" cars.

I think you can get rid of the excessive enrgy by transfering it to heat via a resistor.

Yes but this would be a rather large resistor bank. Then you have to deal with the heat.

Are you talking about the charge cooler? Water has a high specific heat, for all intents and purposes air to air intercoolers work better for petrol engines. Diesel engines are different, they don't use spark plugs they run off pure compression, a water intercooler will have a more stable temperature because of water's high specific heat. If you cool the intake charge too much you will lose power in a diesel.

Are you talking about the charge cooler?

No, I am talking about water-cooled center body of the turbocharger. Water jacket is there to keep the heat generated by the turbine away from the bearings.

Without this you would cook the oil.

The more I behold the Porsche-Indy solution, the more sense it makes for 2014 F1 I think, cleans up the rear aerodynamics, while it optimises the piping to the intercooler in the sidepod and suggests a logic position for the MGUH recovery system?

Not so sure about the xhaust-xit though, what does the 2014 rules say about that?

Then you have your waste gates to locate.

If they use the MGUH to suck up all the excess turbine power and convert it to electricity they will not need a waste gate. At least not for any quantities of exhaust gas in a stationary state.

What happens when the pack is full?

The MGUH will be directly feeding electricity to the MGUK (KERS motor) AFAIK. So under regular conditions the MGUH does not feed the ES (battery).

What if you are blowing the diffuser off throttle and the motor is in regen mode. A waste gate is such a small addition it doesn't make sense to rely on the electrics to do the job.

also im pretty sure the battery and motor will be on a shared bus the power will go to what ever needs it.

just an after thought wouldn't it be more efficient overall to run more boost then try to convert the turbo energy so many times.

Blown diffusors will be a thing of the past from the end of the 2011 season. The teams agreed in summer to have the exhaust exit on the top side of the car from 2012 to make blown diffusors impossible.

WB - I think the question was if this will be allowed?

X - Where do you think will be a good place for a intercooler; indy porsche did not have a intercooler?

[matt21]

I think the best place then would be to place an air-to-water-cooler in the vee as part of the inlet manifold.

Something like this without the supercharger.

Intercoolers were not allowed in CART, but I think it would be best located in the sidepod?

The MGUH does not feed directly into MGUK unit, it goes to the ES storage.

I think WhiteBlue is onto a loophole in the regulations. Energy input into the ES by the MGUK is limited to 2MJ per lap while output is limited to 4MJ (So you cannot get a full charge each lap).

BUT, there is no limit to the energy input by the MGUH (Apart from only being able to use ONE of the ERS systems to recharge the ES).

So if you use the MGUH system to recharge the ES unit, and only use MGUK to propel the car, you can potentially have a full charge each lap giving you a 2MJ boost of the competition.

I think this is wrong.

5.2.6 The ERS may only recover energy from the car via a single MGUK and/or a single MGUH.

ok blown wing then.

My point was if you have a simple failure in any of the KERS systems you lose control of the turbo and lose your ICE engine too. I dont see the teams putting in a singe point failure like this.
