Message: [QUOTE="motoxracer42, post: 666187, member: 670"] Well after waiting a long time for someone else to do it, I decided to test some of Borgs efr chargers. I decided to go all out and get the 9180 (67.7mm inducer) with a t4 non gated 1.05 turbine housing. It's there largest charger available for the efr series. For those of you that don't already know Borg decided to use what they call gamma ti for the turbine wheel which is half the weight of inconel along with a different design all together. It's water cooled and ceramic ball bearing as well. I somehow was able to get ahold of one so I couldn't say no. Here is the 9180 which flows around 94lb/min lol.

I ended up purging the piping and making a pass over all the welds afterwards but this is all I have for pics. By the end, my torch was covered in tape and zip ties trying to get by. It didn't make it the whole way. My new machine and I get along much better. So as you can see individual up pipes, and I actually just machined a cap for the gate cause I didn't feel like playing with it at the time lol. I had no idea how the turbo was going to work out with all the talk about them coming apart when the first few batches came out. I ended up welding it up the night before I had to drive to Idaho and before I knew it, I looked outside and saw daylight. I finished at 830 am the day I was supposed to leave. Fired it up, drove to my house and passéd out. Woke up, and just headed out hahaha. Turbo spools very quick for what it is. It's still too large for towing and has a slight dead spot if you fall down in the rpm range but for me to not complain about it, it's not bad at all. Plus i have the larger ar housing. I hated my 64/71 with diverter. This spools almost as fast but the top end is for lack of a better word, stupid. I averaged around 90mph the whole way to Idaho. I'm looking to pull it off ASAP and try it on a dmax before I get arrested for driving like an idiot. It feels like compounds up top. It never runs out of air. Just works harder and harder. I know I haven't explained much but it's late and I'm passing out. Reply with a question if you have any. Thanks [/QUOTE]
