WOW! Just a trans guy? Maybe you should do some research before more stupidity comes out of your mouth gomezo..... Pete Zimmerman is a Porsche GOD when he comments, and is ALWAYS correct. If you don't know So.Cal Porsche history, here's a bit for you. Pete Z. opened Red Line Service, the oldest Porsche only repair shop in So. Cal. in 1975 after a stint at the dealer. Pete was a full fledged master of all things Porsche running Red Line until I purchased the shop at Pete's retirement in 1999. I had been working for Pete since 1995, after 13 years experience at other well known shops. One of those shops actually held the patent on, and manufactured the pop-off valves. I've built and boxed thousands of them, and installed hundreds. EVERY car that came in got one. Then I went to work for Pete at Red Line, and he explained that a properly tuned 911 didn't require this, and they cause numerous problems, so here's a short list of issues I've seen: 1) Pop-off installed backwards, first time it opens it gets stuck on the air filter and...giant vacuum leak, no start. 2) pop-off valve sticks to the o-ring, doesn't open and blows the box anyway. 3) Pop-off valve opens, the o-ring falls out, and again giant air leak, no start. 4) Epoxy gets old, pop-off falls out. and #5) MY FAVORITE, epoxy gets old, cracks, causes a lean mixture, and voila, the customer burns a piston and requires a complete engine rebuild. This actually occurred on a 74 Carrera.
Your choice, tune it right, or put on an unnecessary aftermarket part that most likely will create more AAA tows than you really want. In the 22 years plus I've been at Red Line I've seen less than 10 or 15 blown boxes, and probably only 5-10 of those were regular Red Line Clients.
