I'm sure it precipitated it, but it was probably waiting to happen. I just wanted the failure at 5k over my home field. :) > I may be wrong, but I thought > that normally the stock turbo only produced about 6 lbs of boost. I think it's more than that, but I'd like to hear the answer to that question again. > I have the stock waste gate controller on mine I had two problems with this. 1. I wanted to run with the wastegate fully open for the first few flights. 2. I'll want boost at height, when the controller thinks I don't need it. Maybe a stock controller with vacuum solenoids for always open / always closed would be a better plan (so long as you dont forget to operate the switches) > I have a pop off valve set at 7 lbs. I have a 6 PSI radiator cap in the intake. I don't think it can blow off pressure fast enough. What did you use for a pop-off? > I'm curious about how many other people are using the 89-91 > turbo, how long they've been running it, and what boost levels they are running. I don't know of another flying turbo. Greg Richter used a Turbonetics T04. > Cozy MKIV 13BT - painting as we speak Wow. You can paint and type at the same time? Very impressive. John
