The WRC engine

[Torsen]

remember... bhp is limited... but torque isn't ;-)

How can You limit bhp? U have restrictor, which ofcourse limits a bit bhp, but nowadays 350-400 bhp is not a problem for these cars. But then again torque is the key word for rallycars...

Here's a thought:

Car manufactures use motor sport for 2 things - Research and Development as well as advertising.

As far as R+D goes, wouldnt a manufacturer benifit greatly from gains in engine effiecientcy through power and torque? With the worldwide fuel fuel situation as it is atm, an engine that produces the maxiumum power and torque for least amount of fuel is going to lead to cheaper production costs (in the end) and theoretically, more sales and profit.

Ok, so what if the WRC regulations somehow require a Dyno run for each competitors car to make sure that a maxiumum HP level isnt exceeded. That would mean that gains in torque are only possible. These gains can then be passed on the the design and manufacture of consumer cars.

Obviosuly there are other aspect to be coinsidered, but perhaps it would assist in closer competition?

Thoughts?

this would meen that the amount of fuel used had to be limited. And there is no way of controlling bhp (other than restrictors). any change in torgue will also affect bhp. programming engine managment will easily get around this. Other branches do this with a controlled size fuel tank and fueling in the race.
