I think some of you might be surprised how much power you can make with a NA VQ. 
It wouldn't surprise me one bit if they can make it 400 hp at the crank. I just wonder what cams they will be using.

actually most of them are in europe, as the vq is a french (renault) engine

The VQ is a Japanese engine which is shared in Renaults, it's not the other way around

Any links to the article online?
If not, what is Sports CC?

Your not going to come close to 400hp with a 3.5 liter VQ. Look how hard it is to make 260rwhp. You basically need every bolt on possible, just to achieve something so minimal. The only way to produce more power is to stroke the motor and or have the ability to make power past 8000rpm.
And thats exactly my point! Those are race cars with unlimited cash flow. The average VQ owner would rather spend 15-20k on a fully built twin turbo, than a fully built 3.5 n/a 300rwhp.

Why are you discussing FI in a thread about Cosworth's NA engine build? Is this really going to turn into another, "FI is more power for less money" thread?

Rather than guessing what you may or may not think is possible, why not just sit back and wait for the results? Prothelitizing about something, when the people actually involved have vastly more experience than you given the subject, doesn't seem to serve much purpose.

It is more than fair to assume that they have a pretty decent amount of cash flow to put into this engine. Cosworth has a huge selection of NA cams to choose from, or maybe they will use this to release some of their own grinds to the public. They have the heads for this build already. The internals could be anything they want. The Jenvey ITB's that IES and Nismo used are available. These are all bolt-on parts available right now, and Engine management is unlimited for this competition. The engine only has to survive for 30 minutes. I think it is foolish to doubt 400hp from the VQ when you consider all that is available to those willing to go this far in the build. IES's VQ35 built for RJN makes 525hp unrestricted. 400hp in a milder build with the aforementioned parts seems inevitable from a firm like Cosworth in this competition.
