Car Is Back Together
So my Steam Speed STX67 finally came in and the install went smoothly overall. The side exit pipe got heat wrapped and small things came together. Only managed to break one thing; the recirculation port on the plastic inlet duct ended getting sheared off. I promptly ordered a new one from Subaru, but the part was placed on backorder and didn't end up coming in till about 4 weeks later. In the meantime, I ended screwing in a flared hose fitting into the remainder of the port, which ended up being sturdier and more reliable than the stock port. A few buddies and I spent the Sunday morning of my dyno tune modifying the front bumper to fit with the new exhaust and it ended up being a huge success. Honestly couldn't have asked for a better line-up of the hole we ended up cutting. I also sandwiched 2 stainless steel heat shields on either side of the bumper to prevent melting and fire hazard of the bumper. Other than that, I made the switch to Amsoil so I am back on a 5W30 formula with an Amsoil filter and supposedly 15,000mile oil change interval. I had been using Rotella T6 5W40 for the duration of this engine's life, but I decided to give Amsoil's legendary claims a try and I'm happy with it so far. As for the dyno, this was my second time on the rollers with Anthony (Drunkmann Tuning). He's a real awesome guy and he knows what he's doing. Unfortunately however, we ran into some issues with the wastegate not opening on the new Steam Speed turbo. After troubleshooting, swapping vacuum lines, and a whole bunch of headache, we narrowed down the problem to the wastegate itself. Whether the wastegate is faulty or if the spring pressure is too high, we don't know yet. At this point, the next step would be to bench test the wastegate actuator to see if it is opening under the correct pressure and/or swap out the wastegate spring to a lighter spring. It's very frustrating and disappointing that we weren't able to complete tuning because of this issue. I am very short on time and resources right now, so this wastegate issue probably won't be resolved until next year. As for getting a chance to get on the dyno for a protune again, it may be even longer. Anthony tuned what he could with the low end power of the car. AFR needed some tweaking because of the new exhaust and such. In the end, the car can still be daily driven as long as the boost is kept low. If I were to floor it, the boost will just keep building until the engine blows. I'll probably take advantage of this downtime with mechanical issues to upgraded such things as the clutch, but that's about all I really have left to upgrade before I'm ready for another protune. PS: I added some custom touches to the interior as well too. ;P

Hi, what ever end up happening with this turbo? Any success?
ReplyDeleteHi there! I don’t think this turbo ever ended up really working out lol. I haven’t updated this in forever. I currently have a stock turbo at SoCal Porting being built so hopefully I’ll have that on in a few weeks.
