Prodrive P2 Supercars, Rallycars, Now and Never Roadcars

the front of a fusion.

You know I sort of agree looking at the two now though not totally (more in the sesne that there's a lot of cars that look like a lot of cars if you take a more broad comparison). They are different in every way, but the style is similar in a broad sense, but more agressive on the P2. That said I love the looks of the P2 but I'm not keen on the Fusion, so it's definitely different enough.

No, we're not talking nuclear explosions here.

But it is known to damage turbochargers over time, don't know what Prodrive have done (or will do) to prevent this on a production car.

 

[Dave A]

The only way I can think of it damaging the propellor over time is if the explosions are too big so they are physically damaging the propellor they are spinning, or if it's just shortening the lifespan of the turbo overall, which would happen since it's spinning more than if it was only spooling up at certain times. I don't know much about them so that's just off the top of my head mind.

Some tuners install anti lag systems similar to this, it does reduce the life of the turbochargers significantly, Assuming Prodrive will not use it too aggressively it may be acceptable I guess.

Then other potential problems arise, like noise, flames, emissions, fuel economy etc. As the exhaust will not have a great deal of oxygen left for the excess fuel to burn with I assume they will use a system like the rally cars use and retard ignition timing greatly so much of the combustion happens as the exhaust valve opens so the air/fuel mixture combustion leaves the combustion chamber through the exhaust to keep the turbo spooling (instead of just putting more fuel directly into the exhaust), which puts quite abit of strain on the exhaust manifold, gaskets, seals and turbo.

All fine for race cars but I am curious how Prodrive will overcome all the problems with a production car that is suppose to last much longer.

 

[Dave A]

Maybe part of the reason it's not becoming a production car then.

Its a shame, after watching the Top gear episode I quite like the car.

 

[YSSMAN]

From a US perspective, I think it could sell very easily, but there may be some difficulties getting over the £40,000 equal of around $80,000 if it were to come to the United States. Added to that is the turbo problem you just mentioned, decreasing the life of the turbos signifigantly, adding to the cost of the vehicle over time.

...Wouldn't it be easier for Prodrive to just build the cars, and instead of running a highly-modified version of the 2.0L Turbo, run the US-Spec 2.5L Turbo with a few extras?

 

[humbo]

Yeah if they do a production version they should do away with the anti-lag system, even without the larger turbocharger I bet 300hp would propel it from 0-60 in low 4's, which is plenty quick.

it does spit flames, all the time.
