Driveshaft problem 16v

Hello, I want to ask a question over this.

I have a pretty tuned 147 16v 1.9 jtd Q2 with stage 2 clutches(bronze+kevlar pads), gt2052s hybrid turbo, 2.5 " fullback downpipe exhaust, Bmc Dia air filter, Hg motorsports 8.2 liters intercooler, decatted and egr off. Peak boost is about 22 psi and we think that it's about 210 hp (it's a soft-moderate map with nearly no smoke)

These are done nearly 30k kms ago. But I have a problem about my driveshafts. Original ones were repaired before these things done. An axle maker guy said that original shafts wont stand that torque. So a custom one should be made. So something other produced with different spider system (I don't know if I'm spelling it true)... Yet one year later (TODAY) while on cruise, car didn't push any power to wheels and I have seen that shaft was cutted like it was done by a saw.

What's the solution here? Should I buy brand new shafts? Or reproduced this one with something else?

How can your faster cars stand that torque? Any way I can find a competition shaft?

Hi, from Turkey, also

I think original shafts can hold that much boost and HP, but the max torque rpm should be above 2000rpm. All the people that I talk and listen, told me stay away from 2000rpm range. After that you are free to go. If the MAP has too much torque opened below 2000rpm and near it, gives hard times to axels.

Call me if you need help..
