Too much power and torque?

So ive replaced 3 center support bearings and 3 guibo for the past 2 weeks , after I tuned the car at 10 psi and it makes 400whp ( still got 14 psi left ) also 93 octane fuel.
Anyways i got a 5 speed manual 330ci with poly bushing all around and a welded diff( which is leaving its home asap) since im driving the car on a daily basis now.
The problem I have everytime I race the car driveshaft support bearing and guibo go bad which sounds like something isnt lined up , but I checked everything and everything was ok , except for the 2 things that go bad. The center support bearing has an aluminum housing and the 2 tabs that bolt to the chasiss keep on ripping out , this time airbag in the car went off ( steering wheel) and battery isolator charge also went while i was on the highway.
Is there a reinforced version of center support bearing , like instead of aluminum I need steel , otherwise I would have to reinforce it myself somehow , because i think that could be the major culprit.
