So that lid has been on/off a bunch, as have a bunch of items on that motor, including the valve covers. If you have not had the lid off yourself, pull it and make sure the bricks have been reinforced. Also, if you have not done so already do a compression and leak down test. I would not be surprised if the blower was ported already. Other questions, how many miles are on it, whats the VIN and if you don't mind saying what did you pay for it?
https://topcheapcar.com/car/Used-201...YN2DT5A5800343 Here is the car. The car was in 1 accident at DENVER CO. Thats what the car fax says.
I am trying these days to see if I can find the previous owner that had the car in Colorado.

I'm assuming that from the early description by the OP that the engine consistently dies/stalls at about 2000rpm.
Sorry if I missed the answer to this question, but have you watched what the supercharger pressure gauge does at the moment the engine stops? Or can you distinguish between cause and effect at that point? I mean that it may be that engine dies because of there being no pressure, or, it could mean that the engine died and the result is the supercharger stops putting out???
When the engine dies, does it cough/sputter, or does it sound like there is a vacuum leak at that point, or any point?

Thx for your time again.

Can't you post it on YouTube? We need to see the gauge moving as the RPM's are slowly coming up and what happens to the gauge at the point just before it stalls and at the point when it stalls; along with the sounds the engine makes at that moment...

No man, I don't have a youtube account or anything like that. I have Instagram and Facebook or email address and Whatsapp.

I think he's saying that if you don't find anything major and manage to get it working properly for a few thousand $, it was a nice find. I agree...

Your boost only gets to zero and never goes positive. At the time the boost goes to zero, there's a bang like sound??? Then under the hood there is that squealing sound that sounds like a slipping belt (you did put a new one on and it's easy to get one that's too long).
Need to know what causes that bang and you need to check the tension on the belt or find the source of the squeal.
In any case, you're not getting any real boost.
Fixing the above may or may not fix the issue, but it will help get to the ultimate fix.
Just some information for your next video:
your video would have been better if you had used a landscape/horizontal view so we could see the entire gauge cluster/DIC. And the focus looked like it was on the steering wheel and not the gauges and that didn't help.

Any way the belt is misrouted and turning the compressor backwards?

Yes I did put a new belt. Before buying that belt, Kong performance asked me what where my mods and told him that I only had the crank pulley and stock S/C pulley and then he sended me that nr of belt that I should buy.
I will make a new video today and send it again man. No prob.
Thx for your opinion bro. Appreciate it.
