Looks like Ferrari will be bringing a new exhaust to Canada.
Link here.Now this is very good news IMO because it means that the team understands the car now and is happy with it's present format and how to improve that. The genealogy of today's F2012 starts with the original test exhaust from Spain. This was a huge failure, not from lack of effect but because it completely cooked the tires, and that happened very fast. So a solution was found blowing the beam wing. For one day in Mugelo we did see an exhaust run that was back targeting the diffuser and it seemed to perform very well. If Ferrari can make the exhaust aiming at the diffuser work this will indeed be very good news.
I'm a little unsure about the "disadvantage" referred to, ie loss of power, the only thing I can think of is that the exhaust pipes will be a little longer and that would normally mean a little loss of power, but it would be very small, unless there is something else I'm missing???
I've also heard there will be a new front and rear wing for Canada further working the improvements already gained.
Rough Translation of the Autosprint article:-
F2012 will be tested on exhaust outlets set aside after the first test.
New or old? For the Gp of Canada, Ferrari has packed the first exhaust system, those was shown at the presentation. Blowing on the outer body, so that the flow of gas, "diverted", reaches and seals the edge of the diffuser in front of the wheels. These escapements were used in the first winter test at Jerez. But the overheating problems of rear tyres, caused by gas, had convinced Pat Fry and his team to desist from the experiment. In the first Gp, F2012 ran well with a solution rather different, i.e. the same body with bent inwards exhaust outlets, so you blow on the rear wing. But the Maranello believed still in the original solution. They performed well in Mugello test (with no problems) with a ' clean ' version of the other discharge, internal ones.
The latter version has raced in Spain and Monaco. Now they are both available. The advantage of discharges ' external ', those who return to Montreal, is a greater downforce. Among the disadvantages, some power loss. Tyre problems seem resolved instead. But in Montreal there will be both solutions: If the first doesn't work, it goes back to the last two Races.
