Alright well i can show you vids and links of the car if you like.... i couldn;t beleive it myself. Here is a link from k20a.org! Look at his sig 654 my appologies, but i swear i saw it spike and hit 41psi and make very close to 700 as another user just mentioned. Here is the car in action aswell!

Ummm, this goes to show you don't the capabilities of any stock valve spring or what even valve float means. You need to realize actually how much tension a valve spring actually has. Valve float happens at high revolutions where the valve spring can't keep momentum and actually the llifters loose contact with the cam lobe.
