what would happen if the cam shift point was moved from 6k to 3k or lower, besides more gas being used? would the car just be really, really powerful all the time? is this easier accomplished with a vafc?

 

I dont think the Vafc's will let you put the vtec engagment anywhere past 4,500krpms...For reasons I dont feel like typing about.

 

You can run the TODA VTEC Killer cams. This esentially runs a high cam profile all the time. Its mostly for race applications though. But what everyone here has said is true, your car will actually lose power down low if always using the higher profile with the stock cams. Other things like oil pressure etc need to be at certain levels too

 

then how does ivtec work is vtec is only useful at high rpms?
