I was at Sebring two weekends ago. Daytona November 1&2.
I've almost finished destroying the Chinese turbo I had damaged and rebuilt. So I'm going to use the damaged GTX2867 I bought from you for the track day. It's still got a damaged turbine wheel.

It's a GTX2860. After I spent +$1000 buying that damaged used turbo I was a little reluctant to buy used again and since I already had the turbine housing there wasn't much difference in the GTX vs GT series.
That 2867 always worked fine for me aside from spooling slow. I datalogged a bunch of +300whp pulls. This will give you an idea how it spooled for me, it'd hit 13psi by 4000rpms on the wastegate:

Scott,
I studied that exact graph when I was deciding what to do next. I figured that if it held together without exploding then it would be good enough for now. The bastardos at Garrett won't do an exchange CHRA if there is any damage to the turbine wheel at all on a ball bearing unit. I would have to buy a completely new CHRA at full price. So that makes the whole thing an expensive paperweight if I don't use it. I guess the compressor wheel and housing would still be worth something as spare/upgrade parts for someone, but meh. I'll see how far it takes me. If I hadn't had it in the garage I'd be scrambling to buy something right now.

3 inch V-band adapter has been welded to the exhaust housing of the GTX2867R by a pro welder. Time to install on manifold and see if exhaust still fits. It looks to be over very slightly from the Chinese 2870.
Say "Aaaahhhhh!"
/doctor
The bolts and screw were just to hold it until it was welded.

Well, I'm here at Daytona. After the first session of the weekend I can report that I need a taller rear end gear if I ever plan to run this track seriously. Using the factory 4.10 gear and only on wastegate 8psi with the EBC turned off, the car is on the revlimiter long before it runs out of front straightaway. 143+ mph indicated (didn't have the GPS running).

Five speed, but the top gear ratio in the six is almost exactly the same.
Megasquirt has begun doing resets while on track and I don't know why. I don't get a signal for my laptop here so I can't easily look up causes. Advice would be great if anyone has dealt with this previously.

I think poor Ryan has blown his engine. He says he possibly missed a shift and zinged it.
And my megasquirt continues to reset more and more frequently. It is barely driveable.
:(
Other than that, it was a pretty good weekend.

Not sure on the ECU. Voltage looks good and so do most of the sensor readings.
Of course I'll help with the engine swap. I'm guessing Ryan is just happy he didn't have to drive my car back from the track with it sputtering and jerking. I was prepared to let him do it but he got a better offer

Is the MS resetting or is power dropping out for a short amoutn of time with the ecu still powered? The first one is almost certainly a loose connection to or inside the ecu, the second is something I struggled with before, it felt like fuel starve, it looked like fuel starve, it was a bad cam sensor/cam sensor wiring.
