Mick, I've seen some spec sheet around saying they won't open at around 100-110 Link to comment Share on other sites More sharing options...

This was with twin 044's and stock rail & reg. so apart from the obvious extremely high pressure everything seemed fine car drove as normal. In saying this I bet the injectors weren't loving it Link to comment Share on other sites More sharing options...
