Son in law's Saab 9-3 TTiD has split a boost hose, its very easy to access and remove, new part ordered but takes a few days so I had a look online to see if any way of bodging a temporary repair.

Some ingenious sollutions knocking about, cutting the top and bottom off a coke can then duct taping it over the split was popular with taxi drivers.

I liked the idea of using a bicycle puncture repair kit. The patches stick on a bike tyre holding maybe 60 psi, probably jumps far higher when they hit a pot hole, and what does a turbo push out? 10PSI at a guess?

Yeah I know the tyre holds it on, so I thought a good wrap with electricians tape was in order. Like half a roll.

I've tried running the engine and revving to just over 4k and it held fine. Anyone any experience of repairs like this? He has a 20 mile commute to work, any thoughts on it holding for a couple of days?

Is this the 150ps 1.9 engine that Vauxhall used?  Looking at around 20psi for those if so.  (Z19DTH engine)

I can't see the patch holding on its own.  But as long as you've done a decent job with the tape, it should hold a couple of days imo. 

Its the 180 bhp twin turbo, BRS tuned to 215 bhp and 450 nm.  It used to be my car. I guess the difference between a low pressure and high pressure turbo must be about 10 psi then, I remember reading somewhere years ago a turbo was about 10 psi.

I'll update the thread as to whether it holds or not, might help someone in a similar circumstance.

Ah, not an engine I'm familiar with unfortunately.  

10 psi is more like Volvo's old low pressure turbo yes.  The 20psi I quoted was on a 90s technology turbo, early VNT.  Tech has moved on since...the 1.0 EcoBoost hits 25psi as standard lol.  1.6 TDCi with the tiny modern VNT is closer to 30psi!
