Boost hoses

[JumpShip]

I've got what I think is a boost leak and want to swap out the boost hoses to prove/disprove this as being the culprit .
Does anyone have their old ones kicking about maybe after an upgrade ?
Ours is a CAAB 102 t5.1 but I think many of them may be the same .

Another question - anybody any idea what's the max boost pressure I should be seeing ?
Currently shows 1.2bar but drops to 1.1 or 1.0 , doesn't hold .
No fault codes showing .

Have you thought of buying something like this instead;

Auto Expel - 400W Smoke, Fog, Misting Machine

Multi purpose misting machine, perfect for sanitising, diagnostics or effects

This would direct you to any leaks in the intercooler too, which I'd have thought be more likely to be the culprit.

Cooler was replaced and upgraded so I'd like to think that's all good .

I would say not likely without fault codes.

How did you get that - surely not at full load? Just revving the engine at standstill?
Is the 1.2 bar above atmosphere, thus actually 2.2 bar?

Thats at WOT , have the info off an obd reader so direct from the ecu .

While driving thus against a load, preferably uphill?
Or just at standstill - no load on engine?

 

[JumpShip]

Under load / driving (on the flat) .
Questioning those units displayed now as I don't remember setting them .

I don't know exact values to expect but as a reference 150hp engines have from factory approx. 2.7 bar pressure (ambient 1 bar) thus engine off the sensors read as 1 bar.

For 102 hp engine obviously significantly less pressure is seen.
