I have a set of hoses from SPA on my truck, with there fancy stainless steel clamps. Never loosen up, look great because they come in a dozen different colors. The only downside is that they are expensive. I know they are being used on some high boost twin turbo trucks and they where holding at last report.
The hoses they sell are silicone and you get all the boost hoses, plus rad and heater hoses.
look in my readers rigs section for pics.
