Wait A Minute Hans Snorkel again...
After re-reading the sport rider article again for the 20th time..( ram air whats it worth) it looks like you guys missed something. The pressure gauge boiled over at the 30mb limit at an indicated 150mph.. Also in the article they were projecting 44mb or more of pressure at 180 mph. The ZX9R's ram air doesn't have noise resonators or any of that stuff, just two ducts to balance the carb floats and everything elese is a straight shot to the box..
28mb doesn't seem to justify how much boost is really going on..
supra
2.6bhp for every 10mb of pressure on a zx9R....

Have read the article a long time ago so can't remember right if their ZX9 was modded but on buykawasaki sites part diagrams there surely are resonators in the ram-air ducts?

If the article projected 44mb of pressure at an indicated 180mph on the speedometer then the zx12r must make well over 28mb of pressure as they were discussing earlier..

They were measuring the "Pressure" in a different part of the system, not at the injector rail were the 12's pressure sensor is. My findings show what the Engine Itself "See's".
I'm sure that if the same sensor that's used on the 12 was installed up in the Airbox just after the filters, you could measure some pretty high voltages! Especially if you suddenly closed the throttle at high speeds!

I thought that the intake pressure sensor "sees" the inside of the TB's below the butterflies????

entropy; I was speaking in "General" terms.  I wanted to make a quick point w/o spending alot of time. You, I and many others know where the pressure sensor is and why it is there.
