This is how my down pipe looked when I had a no boost issue, Prior to my failure to place the air filter properly allowing my turbo fins to be destroyed. Had similar symptoms prior to blowing up my turbo.

Just got it completely together. I have the boost set at 10 PSI. I couldn't remember if 10, 11, or 12 psi was stock. I figured 10 seems okay.
The car runs great and no longer makes a rattle noise when coming on to boost(maybe that was my wastegate slowly dieing).

This just happened to my '86 951 today.
I just had this very same situation happen to me this morning on my way to work. Started out and I was making boost fine (aftermarket boost gauge). The next thing I know, I have a smooth running NA 944. Great vacuum, still 20 inches at idle. Everything else is great, runs fine, accelerates smoothly, quietly, just makes zero boost.
I have suspected that the waste gate might be a weak link since I acquired the car back in May (previous owner shimmed it). Sometimes I would get inconsistent boost levels (have Lindsey MBC, 951Max chips, no cat). Last week it started suddenly increasing boost beyond what I had it set at, 17-18 psi vs 15 previously.
86 951 Driver,
I think I saw in your posts that you went with a Lindsey Dual Port. Sitll happy with this?
Thanks.

I think I will probably find one of the other threads that deals more directly with waste gate selection and get some info there. Probably more appropriate placement than in this thread. Thanks for the heads up.
