Ferrari Mailing List: Re: MB Engine Advantage

[pbennett (pbennett]

Todd, Thanks for the clarification on the details, I mistook dual turbines 
for dual turbos.
Apparently separating in/out turbines allows for using smaller diameter 
turbines due to the heat advantage allowing for a smaller intercooler.

OK then Marco, as the new guy at Ferrari, perhaps you can arrange to buy MB 
engines for the F14-T and give Alonso an even playing field.  That half 
second MB engine advantage can't be overcome with a fancy new wing design or 
more enthusiasm.
