Hi,



Has anyone in Europa had succes in obtaining the two hoses to connect

the intercooler? Nobody seems to have them, and all internet sites that

have them don't deliver outside the USA.



I noticed that SCAT-hoses nicely fit over the turbo and intercooler

connections, and are lightweight and flexible enough to make the tight

curves necessary. The turbo pressure is not very high, the hoses should

have no problems to handle this. And these hoses are not a really

critical component anyway.



Any thoughts about this?

there is a problem with SCAT and SCEET hoses. They are not very robust 

and if there is any suction in the system the inner fabric can 

delaminate and block the hose. There have been one or two accidents 

caused by this with Lycosaurus types.

Engine breathing is certainly critical to continued safe flight

Hi Frans,

  

 Try looking at some of the automotive race car suppliers, they all offer a range of silicon hoses for turbo's and intercoolers.  Failing that, if you want to have a supplier in the US send them to me I will forward them on to you.

Ah, thanks for the valuable info. I meant with "not critical" that if

they were to blow or leak, I would just lose the boost pressure and be

able to continue flight with natural aspiration. I didn't know that they

could delaminate and subsequently become completely blocked. Thanks!

I just looked at it, and it appears to me that there are two types, one

with inner fabric and one without inner fabric. I guess the mentioned

problems only apply to the versions with inner fabric? Both versions are

available from ACS.

Yes, I'm thinking about forgetting the Gates and Goodyear part numbers,

and just go for "any suitable hose with 90 degrees elbow and the right

diameter". I still do not rule out the SCAT/SCEET hose, if my assumption

is right that the versions without inner fabric are safe to use. The

advantage is these hoses are much lighter, and I have them already as a

left over of my cockpit heater system.

Thanks! I really appreciate this offer!

True, but it does get scruffy quite quickly. Wire cuts its way through 
	


the fabric with movement.

Frans,

  

 >>>>>The  turbo pressure is not very high, the hoses should have no problems to handle  this <<<<<<

SCAT hoses are not designed for handling  any pressure. Max relative turbo pressure is around 0.6 bars. I agree this is  not very high but I would not use SCAT for that  pressure.  

  

 >>>>>And these hoses are not a really critical component  anyway.<<<<<<

I do not think so. If the hose downstream of  the turbo blows out, then the airbox pressure sensor will sense the cowling  ambiant pressure. Then the  TCU will widely open the waste gate so  that the turbo tries to provide more pressure. Without any back pressure, the  turbo will overspeed and possibly fracture with the associated consequences: oil  leak and fire.

  

 I would not use anything other than glassfiber reinforced rubber hoses  similar to what Rotax uses to connect the turbo to the airbox.  

 Hope that helps.

Frans,



We used silicone elbows from  http://www.turbohoses.com/



The claim to ship internationally, too.

Hi! D

It is my belief that the turbo flange will be too hot (especially after

shut down) for silicone hoses.  Silicone is OK for water cooling system

only? However I suggest you check this out don't rely on my authority.
