I agree the thinner ply turbo boots are too thin. Here is a link to the ones I got from Amazon as the ones from local dealer where way to thin. Working temperature: -65F ~ 500F degrees；Working Pressure: 0.3 to 0.9Mpa；Bursting Pressure: 245 PSI. This indicates a MAWP of about 130 PSI which seems high, but if you use a SF of 4, that would be about 60 PSI, which is what we want.

Here are the clamps I also had to buy as the new turbo boots are thicker than the original and needed a larger diameter clamp;
