Turbocharging Failures.
I'm a bit annoyed that I wasted a good part of my weekend on a failed turbocharging experiment. I knew I might be facing some slower spool up with the Chinese turbo, but I had no idea I would end up where I am. I still feel like something else is amiss with the motor. But I don't have the energy to tear into it any more at the moment. It is spring, and I need my Volvo to haul bikes and other crap around the mountains. So I'm just going to drive it for now.
On the upside. It looks great under the hood. The larger turbo fits pretty nicely. I fabbed a decent intake pipe setup, and a new downpipe, and a wastegate actuator for the t3/t4. I did some porting on the 90+. Win win win and an A for effort.
The sad reality that I should have guessed would end this way. The tbricks voices in my head murmuring "it'll never spool". I have run this turbo on similar combos in the past, and I don't think it was quite this bad. Maybe my T3 was just fine, despite the cracked housing. The T3/T4 is solid now, no smoke. But just pathetic in horsepower
Full boost at 5500rpm?? Maybe? I don't know because I shift at 5000. The wastegate is set for about 15psi, and I can't even reach that.
I do have a few other tasks to get done on this car, I just wanted to see more power first.
To do list:
-Install the built AW71.
-Install the G80 diff I have.
-Do a burnout.
