Turbos make F1 comeback!

[Nortad]

In recent statements Max Mosley claimed that turbochargers might make a comeback in 2011!

"The engine size will be open to discution, because we dont want engines with a ridiculous out put."

And he says more:

"Engine will have a 15000rpm minimum and will use biofuel"

If one remembers that in the early 1980´s 1.5l turbo engines were putting out 1200 to 1400hp in qualifing form and doing about 10000-12000rpm we should expect some cool racing in the next decade.

My only worry is what kind of biofuel he´s talking about - I hope its E85 or something like that.

Yeah, they´ll go like: vrooooommmm, wooooooshhhhh!

Honestly i´m not a big fan of the sound of bov.

[raif_nijem]

but it will be kind of crazy imagine the sound
18000 rpm then woooooosh

It will sound like the BOV on WRC cars or something - a very high pitch sound, or it will be unoticed.

im pretty shure it will be unoticed. those cars are soooo loud in person but thats crazy if turbos come back it will definitly be interesting but i think with going f/i it will put down the reliability of the cars. but bio fuel.....fuk that shit

Well if turbos do return to F1 we will know definately whether bov's are one of the automotive worlds biggest gimmicks or not!
F1 never used them.
Grp C sportscars..the most succesful the 956/962 never used them.
Group B never used them.
And I thought but could be wrong that current WRC cars only use them as a form of boost control since they run antilag... When they close the throttle it sounds like they don't actually run a bov imo.

Enough evidence here imo to suggest they are nothing more than a big noisy attention getting thing. I know all the reasons why a bov is 'so good' but all that info comes from the people that are selling and making them. I have NEVER seen any performance gain (ie keeping turbo spooled up) or excess wear in any of the turbos I have played with. And the FC RX7 workshop manual call it an emissions device- nothing more.

None of my turbo cars hav a bov fitted. And none will until I see REAL proof that they improve performance and turbo life.

Back on topic: I certainly hope it does happen. To me its a pity that the worlds highest form of motorsport can't use this technology atm.

I would assume recirculating BOV's/BPV's would help with the old school journal bearing turbos as opposed to the newer ball-bearing and dual ball-bearing turbos for turbo life. But I'm no turbo expert nor have I actually seen or heard of data supporting this. I've actually ran a vented BOV(something I'll never do ever again) a long time ago and found that it hurt my performance/response and screwed up my A/F ratio. Of course this was do to me still running with the stock AFM no EMS or anything, something I'm sure F1 cars have nothing worry about. Stock BPV works just fine for me, plus no irratating noises or looks. I wonder how durable these newer turbos are? Well I guess we'll find out.

Perhaps. All the turbos I have played with have been plain bearing type. The cars I mentioned above- even those from F1 were plain bearing. I have not seen any wear in my situations. From the figures that I have seen the loads imposed upon the compressor wheel and shaft a negligible- but in saying that I'm not 100% sure about the said figures.
Even some of the drift guys are moving away from bov's due to reduced performance. I can go into plenty of detail about this but this is not really the thread for it.

Really do hope turbos make a return though!!!

I remember reading an interview with one of the drivers of the time, talking about the Renault turbo F1 car. He was saying no one really thought to much of it at the time. Then at one race where the cars were hitting 155-160mph on the main straight, the Renault screamed through at 175mph! This made everyone take notice.

Will try and find the article. It has the exact details.

[Nortad]

Do try.

I never heard any gains out of BOV, the justification I heard for them was to prevent damage to the turbos.

In WRC or Rallicross thir sound is that high pitch sound like scratching metal. I thing SevPP is right about being part of the ALS sistem.
