Message: [QUOTE="KCTurbos, post: 905423, member: 13852"] He is one of the guys I have been talking to. It seems like standard arps start to stretch at around 40-50psi... If your prep work was perfect, surfaces flat, then a little bit of stretching is ok. But any imperfections and even the smallest amount of stretching will leak. Now once you get above 50-60psi then IMO standard ARPs will not hold up at all. Interesting note... you can torque standard ARPs to about 215-250 without any problems. The reason you torque them down that much is they stretch slighly and reach their maximum tensile strength after being stretch to that point. H-11 and Extreme studs recommend a much lower toruqe rating of around 185... supposedly if you torque them to 215-250 like the arps then you risk a chance of pulling the threads out of the block. I have never heard of that actually happening but the point I am making is that the h-11 and extreme studs options are not supposed to stretch [/QUOTE]
