Driving around with the IC piping unplugged = possible danger for the turbo ?

Driving around with the IC piping unplugged = possible danger for the turbo ?
the engine is a B18c1 . I drove the car around for about one week with the turbo connected to the exhaust mani, but it was spinning freely due to the fact that I have unplugged the IC piping.
I redlined the engine a few times during this period.
could it have possibly led to turbo " overspeed " , and cause possible damage to it ?

lol, why would your redline it if your breaking it in? from what i hear u baby it time to time and u get on it to seal the piston rings or whatever, but i dont think that means redline it

taking your motor to redline somehow proves to have better results in the long run. Your rings seated almost immediatly. I did half babying and half redlining and let off the throttle during break in 16K miles ago and took it out recentyly, everything looks perfect...
Don't run your turbo with no IC piping, you're over revving the turbo and it will shorten it's life...it's not good for the seals...
Either run it NA or run it in boost cycle

I mean with boost, i.e. run it with the charge pipe connected..

your turbo's life has been shortened. If you must drive the car with a turbocharger in place but not operational, disconnect the internal wastegate if possible, or dont rev the engine too high. it's simply not good for the turbocharger either way.

I've heard that babying your engine during break in is 'bad' also. Too bad I heard too late. About ten years ago I babied my break in...
Probably the only way to see if your turbo got damaged is to just try it out and see how it goes. Maybe its still ok. Let us know how it goes.

I have a 1 bar WG spring, it's a little high for a break-in
I just soudld have removed the wg spring but now it's too late
I removed the turbo to check if it was ok, and I did notice a little bit of oil on the intake side of the compressor. not much, but is it normal ?

I seriously doubt you did any damage to your turbo, if you only redlined int a few times.
Think about it, on most setups with a decent sized turbo, you can rev it to redline in neutral without building much (if any) boost. On a naturally aspirated engine (which is basically what you have with the IC piping unplugged), your really not producing much exhaust gas, even at redline. Its not going to spin any faster than it does under normal use.

that makes sense, except for one litthe thing : If you rev the engine into neutral, it sees no load. But my engine was on load.
Do you think it could make a difference ?

yes, because the turbo was getting more and more exhaust gas, with no way of calming down the flow. The wastegate works by using boost pressure to open the dump valve. If you dont have the charge lines hooked up, how is it going to see that boost pressure to calm the flow? It wont, therefore your turbo probably just saw 100-200k rpm. Have a good day

haha.
About what RPM ist it supposed to normally see ?

Again, on a properly sized turbo, a naturally aspirated engine is not going to provide enough exhaust gasses to overspin a turbo that much. I used reving the motor in neutral as an example. Even with the wastegate closed the entire time, there simply is not that much exhaust to spin the turbo to the stratospheric relm that everyone takes as gospel, just because they heard someone say it way back when.
