So on Saturday I took my car to a local shop that has an in ground dynojet setup. Real nice guy and pretty decent priced too. Anyways, put it on the dyno and I was running pig rich the first couple of runs. Finally got it tuned decent by bumping up boost and leaning it out, still running 11.2-11.5:1 on C16 trying to lean it out by getting more boost out of the turbo.
At first I was running 15psi just to get a decent setting on DSMlink. BTW: 1600cc injectors work perfect with DSMlink if anyone was wondering. Decided to bump the boost up to 25 after the first couple of pulls. Then to 30. Made the first pull at 30psi and BOOM! The turbo explodes. Made 438whp and 357ft/lbs Tq at 6500rpms. Never saw 30psi on my boost gauge. Hit 26 then it blew. I looked back at the DSMLink log and I was flowing about 47lbs/min and I hit 26psi by 6300rpm where it died. The turbo is rated at 85lbs/min so I still had a ways to go!
Here is a video of the carnage and the dyno graph. Note: Watch the car by the passenger headlight when the RPMs really start winding up. You can see everything shift and the car move about 1/2 a foot on the dyno when the turbo went. Pretty interesting if you ask me. Talked to the guy I got the turbo from for warrenty purposes and I will have a new one in my hands by the middle/end of next week. Hopefully this doesnt happen again. I have a feeling it was a defective part.
