aes 390, d1, someone help please Heres the story on the car, its long, so bear with me. Got everything up and going, got all the bugs, leaks, and everything worked out. Car made about 16lbs with the blower, till I blew a pipe off and its never been the same. One night I blew an intercooler pipe off the car, it got sucked up under the k member, it also just so happened to contain my mondo bypass valve. Ever since then, I have never been able to get the car back right. I wanted to go to the track in two days, I replaced the pipe, not the bypass, car never made over 11lbs. Bad part is the night I went to the track, I blew the trans in 2 passes. I've since done a th400, and a 9" rear. I've done countless boost leak tests, there are none, I've eliminated belt slip I am pretty sure. I was over spinning the blower when we tuned, and I still do. I have also since replaced the bypass valve. I guess what I am asking is, can I "half ***" mess my blower up by blowing a pipe, by overspinning it? I have the ati balancer 7.65 I believe it is, and a 3.4 pulley. Any questions feel free to ask, I am all out of ideas to make this work again. I am ready to throw the blower in the river.

I know I am rambling but I have had a few and I am tired of this damn procharger. Nothing I do can get this thing like it was. I am all out of ideas. I wanna send the blower in to have it looked at but I have heard horror stories on here about how the f*@k people on the price to service these things

I have the stock j bracket with the "poor mans method". I say I have no belt slip because even after all this, I ran that belt for a long time with no issues. I have even slapped on a new belt just to eliminate that. The one I took off was immaculate like the day I put it on. I went through belts when I first started this project trying to figure out how tight they needed to be etc, but this one has been on since last yr with not so much a nick on the inside of it. And I had the car up to the desired amount of boost at one time with no issues

I have seen belt slip on a boost gauge, and hpt, I just dont think thats whats going on here. Boost comes in to say 11lbs, and just sits there through all the gears, never falls off even the slightest bit. Like theres a ceiling there the car cant get past
Have you taken the intake off the blower and checked the impeller? Any way it Could it have sucked something up and through the blower when the charge pipe came off?
If the impeller looks normal then it is either a boost leak or belt slip, don't give up just take a break maybe have someone else look at it never hurts to have a second set of eyes when you are looking for a problem.

I have taken the blower off several times, impeller has a tiny knick on it, i have even capped it and tested it to make sure its not bleeding somewhere. I did take a break, majority of all this happened last yr, and now im back tinkering with it again.
I know when i test everything the bypass seals great, unless for some reason it wont when i drive it idk. This is also the 2nd bypass i've installed.
Im starting to think its a bearing issue. I just dont have anything to blame it on anymore. I tested the intake by itself yesterday and fixed a pin hole leak i could hear coming from it. Im goin to go get fittings so i can test the piping independently from the intake and put about 20lbs on it. I used to only put about 5lbs on tye system when testing, but i am wondering if theres a leak somewhere that only shows up once i put over 10 or so lbs on it.
We've all seen belt slip and from my experience when you slip a belt, it destroys it in almost no time. The belt i just took off has been on there since all of this happened, and looked immaculate on the ribs. Is it possible it was slipping and never harmed the belt? It had plenty of street miles, tuning, and 6 track passes on it.

Well, a belt is an inexpensive test to see if it helps, granted, it's a pain to remove the blower and install a belt, but who knows, the belt might have stretch a little and it's only spinning at upper rpms.
What kind of blower intake you running? Maybe you have an air filter or rubber hose sucking shut a little?
You might try running without a filter and see if the boost spikes up. This also tests for belt slip because less power to spin the blower.
Also, you could put a good coating of VHT (PJ1) on the blower belt to further eliminate that as an issue.

I went through that with my vortech, ran fine till I punched it then at 6 or 7 lbs boost, that was it. Tried replacing blow-off valve , the belt and finally figured out one of my hoses was collapsing.

Thanks for all the help. I have tried everything listed, I am smooth out of ideas which is why I have posted. I wasnt able to get any fittings today to cap the piping off independent from the intake and test to 20lbs. But it will get done this weekend for sure. i am just soooooo sick of this **** and I have got to figure this out before I part the car out or burn it to the ground.
What about what I said about slipping a belt?? I had that sucker on there a long time, if it was slipping it woulda had to have been destroyed. I have been through my share of belts when I started this project. The car went 10.70's@127 with a 1.60 60ft with the boost that is made. I went 11.60's cam only without the blower install to give you an idea of what kinda power its currently making. And with the amount of money I have in this car its just a slap in the face what its doing
