So the Dyno went well with all AFR's sitting almost right on 11.0
Achieved many good runs and kept making adjustments as we still had plenty of room on the injectors as they are now scaled up to 660cc. Absolutely no nock detected and it had more but 300hp was the goal and we made that on a safe tune. I left the dyno sheet behind so Matt will post this down to me. I'll post it up when i get it for bragging rights
Made a respectable 227kw on the mainline dyno and over 900Nm of torque!! Also in I mode I now average a crazy 7.0L/100km on the highway! Not bad for a family wagon with over 300 horsepower at the wheels.
The downside.. We kept getting a bit of waste gate creep or similar coming in. Not sure what was going on there but we sorted that out a bit with the angle of the actuator arm and length. I had a fair amount of preload on it which we backed off and this helped. But it gets worse.. 2 hours later cruising down the highway enjoying the successful mission to Coffs with the wife and bub with me I boosted hard out of 40kph road works into a 110 zone at Kempsey. When I got off the gas we heard a loud woosh sound and both asked each other "what was that?". Then no boost pressure.. Just a sound best described as your standard domestic vacuum cleaner when putting the car under load.
I immediately looked behind for smoke (and cops) but nothing. I pulled over to check if a hose had popped off. All checks turned out fine. All vac lines in place. I rang Matt and we thought it must be one under the top mount. On limited time (sun setting) and the side of the highway on Kempsey (not a great place to be stranded) I did a few other checks and spoke with matt on the phone. The car idle was fine, and it drove as normal off load but could not make boost pressure.. So I nursed it home.
At Buladelah we stopped again to feed and change the little guy and while i had half an hour, off came the TMIC. And all the hoses were ok. Everything looked as normal. No oil, no smoke, no hoses having off or split. And now its raining by the way..
Got in late with a tired and sick bub and we crashed out. I woke at 4.00am and got stuck into the diagnosis pulled the actuator off and manually worked the dump valve linkage, seems ok. Used compressed air at a low setting, actuator working. Pulle dthe TMIC again and checked the throttle inlet hose, all good.
I put it all back together and drove it down the Marshal at Autocraft who drove it 100m to say Yuck! Sounds like the turbo. So its booked in next monday to find the problem. Ill let you know the outcome.
