I got my KB charger kit today, and by what is encluded in it you can justifie the cost. Many changes.
17 more rear wheel HP.
no need to reset knock control it does it for you now. aftwer 4 knocks the supercharger goes to full bypass,we no longer have to pull up on the throttle, to go to boost into open loop
We now have the Optimizer utiliziing a mass flow meter for precicion fuel delivery, and spark control
So far I am very impressed with the kit. every wire hose, screw and tie-wrap is included
the new fuel injectors are mounted on the Supercharger

How much $$$ did you piss away for 17hp? A hyper tech power programmer is only 350$us (20hp), and a simple throttle body mod that can be done at home worth 15hp. wow for real it's got to be better than that!

That was from the old kit a 17HP Gain
235 flywheel hp from a stock 4.7 and it dyno'd to 194 rwhp then you're only losing about 17.5% thru the drivetrain. If you use that figure then 270 rwhp will end up looking like 327 flywheel hp.
You won't have to worry about the rods at all with just 7psi of boost. I've put 14-15psi of boost to mine without any problems. According to the online calculators that are based upon weight and mph at the end of the 1/4 - my 4.7 should be making between 450 and 477 rwhp depending upon which calculator you use. My math shows that figure to be in the 535 to 560 flywheel hp range. An accidental increase to 30psi was a different story. At that point the rods did fail.

Uhh, I'm kinda confused about this whole thread. You went from 270 hp to 477 hp? How did you do that? Did you change a pulley or something? Is this still a 4.7 engine?
