@ Dave,I never see below 30psi anywhere on track,and thats with the oil up to 120 C.Off topic slightly,but I don't think we've met before???Which does'nt mean too much in itself,its just that I've met most of the big trackday players off the RS scene over the years.You doing any of the RS trackdats this year,would be nice to have a chat???Regards,Micky
