I actually did, if you noticed, my last statement was listing some of the shortcomings;..."along with the stock intake"...but I digress...
In clarification, I completely disagree with you there, as the potential flow of the type 44 airplate is well over 1200 cfm's of air without much probs (without severe turbulance)
You really neglected some basic rules of flow; as you could easly flow massive amounts of air with just higher velocty, the issue is: can you supply the correct proportion of fuel for it.
I race Vw's, and know plenty of tuners (techtonics, older Drake, ect, to name a few, that have built stock based HIGH HP systems) that have built STOCK cis sytems that can easliy make 180hp with 1.8 4 clyn. motors.
Thats with the same basic system made to develop 78 hp stock!
I would venture an educated guess that a Audi CIS system has the same amount of "tunabilty", and would I agree with others that other similar CIS sytems make in excess of 300bhp.
I KNOW stock audi systems are almost identical (I'm A former VW/Porshe/Audi mechanic). The only real differeces are the amount of inputs that control the sytem, but they all REALLY do the same thing; they ALL have the same basic components, pumps, fuel dist, ect, some just have more control of ignition timing, injector pulse (Motronic), ect...In reality, any Audi/Bosch sytem COULD be made to work the same way, and I would assume that anyone capable of building a motor that "might" make 300bhp more than likely has the skills to make a stock based injection sytem work corectly...it really would not be a tough job with the right "off the Shelf" parts...and they (the parts)are out there.
