Default The basic principles are rock-solid; but granted, the costs would vary. Costworthiness is the issue

The basic essenstials are just sheer mechanical physics: get the engine to move more air, and move that larger air volume faster, and you achieve more power, end of argument (provided it is managed properly, mind you) THAT is what becomes the big issue, though--which is where standalnoe management comes in, a la Stinger, Tech II, etc. But again, that takes time, costs money, etc etc

I know it is not a bonehead job, takes time. But the basic principles of serious headwork, agressive cams, ramped-up electronics and management and etc are indisputable. Sheez--would love to have a good 10K to mess around with and actually have this done---see 400+hp in naturally aspirated--which I have no doubt can easily be had.

Default You're assuming that all that will work.

No one has been successful with cams and as far as tuning, Good luck. A standalone unit will not be easy to make mesh with this car, if it is possible.

Solution...VF SC.

Default lol. A good VW shop can port heads for $1000. Skip cams. Get downpipes and race cats.

build a legit ram-air system with a K&N and avoid so called "cold-air" intakes..

that's 400 hp

Default Sure, the basic principle, 'make the air pump pump more air' is sound and basic hot-rodding....

principles apply, but I'm saying that it's questionable because no one has documented what results are to be gained from doing any of the steps you mentioned. If you can get it right, yes, the thing will hum. But is the Schrick cam profile perfectly matched for the anticipated flow of the modified heads? Where do you remove material or reshape ports on these heads to get the best results, not killing low end, etc.? How well will the now mismatched stock intake work with the modified heads? What injectors do you use? And will anyone besides Garrett be able to get this thing running correctly? Making it work is questionable because no one has done it and documented it. A couple have guys have done some parts of this and achieved some success but not all of it and what was done wasn't well documented.<ul><li><a href="https://forums.audiworld.com/s4b6/msgs/371667.phtml">https://forums.audiworld.com/s4b6/msgs/371667.phtml</a</li></ul>

Default Agreed. And I know there are no 'easy solutions'.

All too often we want to make things out to be easier than they turn out to be. But the principles are indisputable. But as the old saying goes, the devil is in the details. Stinger standalone can do almost anything, though. it is amazingly flexible, capable of modifying flow and advance at incredibly small intervals--- at every 50rpm. Injectors would be another issue still--finding a 'happy medium' would probably not be a 'happy' process---but I am certain it can be done. All too often, tho, we are satisfied to have someone else do all the 'ahrd work'--a la VF, AWE, PES---none of whom has actually fielded a new SC system although I keep hearing bits and pieces here and there.
