Turbosmart bleed valve incabin?

Hello, wanted to check if anyone knows is it ok to run a bleed valve inside the cabin? Or would the extra long piping cause problems? I recall hearing it needs to be as close to the wastegate as possible?
Thanks
Joel

Thats right, it needs to be close to the wastegate for stable boost control. Having it as far away as the cabin would cause boost spikes and unstable boost control, not ideal.
I use a turbosmart bleed valve in conjunction with a setup I made myself so I can control high/low boost from inside the cabin (electric control of solenoid via switch), it works very well and has the best boost control of anyhting I have tried so far.
I can PM you details if interested and show you the setup at WSID.
Cheers.

OK, I'll bite . This may be my dumbest question, yet - but why? I just can't see it being any harm to the occupants or other motorists.

because pressurised air is in the cabin i spose? and it a seal went in the turbo oil could come through the hose.
i dont think its SUCH a bad thing to have it in the car, i mean a boost spike isnt too bad. it will just spike as it comes on boost, because the presure has to build up in a longer volume of hose. its relatively safe, as the spike will be at low revs when there will be adequate fuel pressure. my friend has his in his car and it does have a small spike, but i havent noticed the control to be bad, seems pretty smooth to me.
having said all that its very easy to run a solenoid and have a switch inside the car.

Jeez, I can understand it being a bad idea performance wise, but saftey? I mean, a boost guage introduces pressurised air to the cabin, though I haven't heard of any fireballs indiced by them.

I used to use one of those turbosmart 'in cabin' bleeds under the bonnet of my car (only because I got it cheap!), and found it actually worked pretty darned well. I think it's really only full sikness factor that would give most people the desire to run it inside the car. Plus, because mine used to be connected to the manifold AFTER the LPG carb, I suppose it was full of flammable vapour.

what are those turbo smart bleed valves like? i assume we all talking about the same ~$100 ones that look like this
i'm lookin at gettin one to run a little ie 2-3psi more boost in my mr2. would this be suitable or do they tend to spike a lot, or is that spiking because of the lenth of hose you use when plumbing it in?
i see no point in gettin electronic boost control or a dual stage controller as im not running mega boost.
Cheers

They work well and are priced well, as far as spiking goes. They spike on some cars and not others. Keep the line from compressor housing (best spot to run from or directly after the compressor housing) to the bleed valve to the waste gate actuator as short as practically possible.
If you like to tinker like I do, you can use different gate springs in the bleed valve to control the gate response and to some degree the amount of spike you see
