To get to the HP question, fueling is the first most important thing as stock CIS isn't really designed to support that level of power without at the very least doing fuel head flow modifications. EFI would be the best approach, as Heat'n'cool has listed. The rest is cams, air flow (intake and exhaust) intercooler and turbo selection. It doesn't really take a whole lot to push close to 400 hp using stock CIS, but going beyond that takes additional $effort$.

Good list of much of the stuff a guy should do to support high HP and not blow a hole in things. No mention of what level of boost you're running, though. Gotta be 1.2 bar I would guess.

Like Mark said over 400hp it really gets expensive to run cis. For an engine running this much hp you will need fuel which is why I went to EFI with twin plug. Works great car runs like a champ.

Kevin, you're going to regret ever asking! Go here for some head spinning reading, especially if you have limited knowledge on how CIS actually works: http://forums.pelicanparts.com/911-9...ight=fuel+head
CISflowtech http://www.cisflowtech.com/ is one outfit that can modify and adjust your fuel head to flow more fuel.

Ten years or so ago I got the itch for big horse power and at the time figured it could be done for about 10 large. Question I got is, What's the price tag for 500 WHP these days?

Both Rennlist and Pelican have some very seasoned individuals that can guide you through most anything. I tend to lurk around Pelican a bit more because it's more of a DIY community. Rennlist lately seems to focus more on topics of the car's worth, etc. I belong to both and steel shamelessly the information that I need.
Join up with the Pelicanites, too. Just register in the upper left hand corner of the tool bar.

500hp can be done....but too many chase hp. Reliability should be your #1 goal. In order to get 500hp while keeping your engine reliable will require proper planning. Efi will probably be used..some say cis can take you there....but again it has to be done with reliability as the priority.
I have 410whp with a .8 bar. My car has 3.4l twin plug, custom cams,garret gt35r,port and polished heads,Ruf intercooler,ghl exhaust and Ruf muffler....it's being managed by a Motec M84 ecu(efi). My plans are to run a 1bar but no more. My limitation is the Ruf intercooler...but due to nostalgic reasons...I'm sticking with it for now
