Kpa explained..... For new users of LS1Edit who, like me, when looking at the tables that LS1Edit showed and wondered what the heck is a Kpa, I have found the answer. A Kpa is a measure of pressure. To convert for example 100 Kpa to PSI, you multiply the Kpa number by .1450377 which gives you the absolute pressure of 14.5 PSI, which is the most pressure a NA engine could deal with. This goes towards zero as you mash down on the throttle. To find out what Kpa is in inches of mercury, or more commonly known as vacuum, for the same example you multiply the Kpa number by .2952, which gives 29.52 inches of vacuum, which is pretty much a as much vacuum as you are going to pull on this planet.
Hope this helps someone, I know it helped me out.

Re: Kpa explained..... Kpa, as in kilo pascals?, weren't too quick in science class were you? <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> As far as maximum pressure that the car will see on planet Earth, well, that's also a function of the barometric pressure, which we all know is variable. Grant it woun't change worth didily-crap really, the important point to remember is that it is not fixed. And maximum vacuum is not as important as to how well your car can maintain a vacuum in the crankcase at higher throttles. That's the key. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Re: Kpa explained..... since jade brought it up, how do you convert the KPA into something i understand? inches of mercury? and psi if it will go into presure. Jade's numbers don't seem to work

Re: Kpa explained..... Well I got my calculator and chem book out for y'all <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> .
1Pa(pascal) = 0.00014503773774 psi(pounds per sq. inch).
1Pa = 0.00029529987508 inHg(inches of Mercury).
1Pa = 0.00401463076 inH2O(inches of water).
And 1kPa=1000Pa.
