Well cold will get you a general idea. May not be 100% accurate but its something. you doing a comp check on ur KA jason? Like everybodys saying, all you need is for the starter to kick off. Listen to the engine and let it spin 5 times and thats should give you some number. I cant remember whats the minimum you should be getting for the KA but if its your KA...itll probably be lower than its supposed to be *170 ish i think maybe higher* but if you get something lower and they are all within roughly 15psi of each other thats aites for now.
