My rear mount turbo setup

Just Saturday. I always hate Sunday events but if this one sucks on Saturday I'll go on Sunday for now own. I guess a positive to waiting hours to run is it gives my 6l80 time to cool lol.
I've done boost leak checks and everything is perfect. Thankfully once it's going it keeps going and I'm hoping the lazier low end will help with traction at the track since I won't hit the tire so hard. I figure once I do a cam it'll help some and I hope to do that before WannaGOFAST. But I enjoy driving the car so much that I really don't want to take it apart again anytime soon haha.

I've put a couple hundred miles on the car this week. Everything from stop and go to crusing at 80+ on the highway (which is over 2k with this z06 differential) for an extended period of time. The car hasn't skipped a beat and when I get an open place to romp on it I take advantage of it. The Trans cooler is keeping the temps down and even after a few pulls back to back the coolant temp doesn't get much over 205 or so (I was worried with the intercooler basically blocking the radiator. I haven't had any smoking issues either so I think this turbo draining to a reservoir and the scavenge pump pulling off of it is really helping. It's been a long time since I've had a fun street car with decent power and amenities like PS and AC. I just really have to do something about how loud it is. I'll concentrate more on that after street car take over.

UPDATE!
Made a separate thread about the track outing and didn't update this one.
The car is lazy out of hole so the converter probably needs to be adjusted but the back half makes me happy as it shows the cars potential. Also the car runs out of 4th right as I cross traps so I need to turn it higher, but I know the cam isn't carrying power any further. Car leaves on 0 boost and only makes 2psi at the top of first. With that said I'm
Gonna wrap the exhaust and have a turbo cam I'm going to install. Probably do meth too if I have time.
This is on straight pump 93 and driving to the track. Tire is a MT ET Street. Overall the car ran 4 10 second passes all around the same MPH. I've put a few hundred miles on it since then too. I'm loving this thing.

Thanks guys I appreciate it.
The car sounds wicked on video from behind due to the turbo being so loud but during normal driving it's super droney so that's annoying. I have an idea for a muffler system but it'll be a while before I'm about to do it I'm sure.

Finished the cam install up. BTR STG 2 turbo cam with his springs and pushrods. This is idling around 700rpms. Still have to order a few meth kit components then I'll get that on and back on the Dyno it'll go.

I will def do so. I'm curious how it'll spool compared to before. I plan to wrap my exhaust as well and put a turbo blanket on so I would love to see atleast 500 rpms sooner between that and the cam and for the car to actually make some boost in 1st gear at the track. I'm going to work on the foot brake portion of the tune too to see if it'll get up on the converter better.

Got the cam in the car and meth installed and retuned it. Boost is 12psi falling to 10.5. The air temp dropped 35 degrees or so. The car holds out power good considering the boost stop till 7k and comes into boost sooner and harder. Just hoping the Trans stays happy. Lol.
Should be doing some 1/8 mile runs this weekend

Yes. Minus the portion that runs beside Trans and holds turbo. I plan to get to that soon. What minimal free time I've had I had to put towards getting the meth kit on and cam done.

Went to a local 1/8 event yesterday. I ran the heavyweight class. I had to be 3500lbs and my scales at the shop said 3450 with me, a full tank and the drag wheels on. So I put 2 25lbs plates in the car, one in each rear storage compartment, and hoped my scales were light. I got there and I was 3551, filled up right before getting to track, with the weight in. So I left it.
I never got the 1-2 and 2-3 shift points perfect but they improved throughout the day. 3rd isn't locking as fast as it should either so that's hurting me. The converter just won't work for drag racing. I'm going to have to get it adjusted so I can get this car to actually leave with some RPM and boost.
I was still happy to drive the car an hour to the track, make a handful of passes, make it to the semis in my class and drive it home. The MPH shows the car is making some good power and I know it'll pickup up a lot of ET and mph once the converter and Trans settings are right.

Hoping I can drag the stock engine out for a year or so lol. For a street car it's already really fun and gonna get me in trouble if I keep doing 2/3/4 pulls lol.
