[QUOTE="TARM, post: 263344, member: 578"] Dave, I am with you and have been saying this for years now. If you think about it at the basic level CP which is what lifts a head is correlated to FTLB torque. Of course technically you have when the combustion event happens and its curve that certainly can have an effect but given things being equal CP and tq have a direct correlation. Lets open this up a bit further and add even boost or positive pressure into the mix. I would say even boost does not have a direct effect on HG issue. Think about how the same boost form different spec turbos have significantly different effects on actual power output. Sure we can look at boost and say you need fire rings or studs ect but is it really the boost or the power we know that with the boost and setup its going to produce. Its not really the boost psi it self as once again you are only talking about 50-200 psi being added. There is no question that high BP is a bad thing and can cause damage to parts and rob power combine with some off tuning and all sorts of bad things can happen. [/QUOTE]
