I decided, now that my turbo is dialed in, to do a quick write up on the Hahn Super 20g Turbo Upgrade. First a quick pic without the heat shield.
I didn't do the install myself, instead I had Sin City Performance do it. I've always used them for projects that I don't want to tackle myself. Mike, Max and team there are great. If you're in Las Vegas and want a performance upgrade, they are the guys to talk to. Overall the turbo and install went relatively smooth. Hahn was available to my installer for questions, but their experience in installing certainly helped. One thing to note, the power steering reservoir had to be relocated. The quality of the BOV setup and the mounting adapter flange was excellent. Hahn was great, there was a delay getting my turbo out, so to make up for it, Hahn didn't charge me the deposit on my Tri-Fecta cable. I literally had this for several months and never a complaint from Hahn, just a friendly reminder he did want it back at some point.
We did run into one small problem completely unrelated to the turbo or install, my RPI downpipe had cracked. A quick weld and it was fixed. One bummer in this is the dyno broke down while my car was on it (literally), so no pulls and I haven't been back yet, but that info will come soon.
Tuning was definitley the biggest challenge in this. Once the Tri-Fecta was loaded up it had crazy power but also had crazy backfire. After a couple updated tunes it was still backfiring. Since I had the Wester's tune originally with my car I reached out to Lyndon. Lyndon was awesome and stuck by his "updated tunes for life" rule. His tune had the same initial problem and then he mentioned my spark plug gap. Doh! Once the gap was adjusted, the car was rocking. Traction control must be turned off or you have massive surge when you punch it. The power comes on fairly early, but the lag is evident compared with the stock turbo. However, once it comes on it comes on strong and just keeps pulling. The advantages in the mid-range are really evident, the car just wants to keep going, there isn't that dead spot between 60 and 100. I also want to mention Vince at TriFecta was great as well. Both tunes work very effectively now with the gap adjusted. I prefer Wester's overall, seems to pull stronger and sooner.
Overall I'm incredibly satisfied. The Sky feels like a completely different car. Compared with other turbo upgrades the price was more than reasonable for the power return. I've almost lost my hat (literally) several times since the install was complete. For folks like me that are bolt-on mechanics or prefer the 350, I would say the one thing you have to keep in mind is try to be patient. This is not a simple process and does take a bit of time to get everything just right.
I'd be remiss if I didn't thank Jeb (Monadzback) for his initial write up on the Super 20g and advice after the fact. Without that I probably would have gone a different way, but due to it I waited for Hahn to make it available and I'm glad I did.
BIG thanks to Bill, Vince, all the guys at Sin City Performance and Lyndon Wester. You guys are awesome!
Lastly, if anyone is considering this and wants any more info, please feel free to PM me. I don't stop by as much as I used to but more than happy to get back to you at some point.

That's what I'm using with Wester's tune.
