Post #289
There has been a little 'Design Development' on these regarding the ICV mounting location.
The plan was to mount the ICV on the inlet manifold (as it currently is on your standard engine) and use a non-return valve on the ICV to prevent boost escaping under throttle, but this would still allow the engine to breather under vacuum (idle/part throttle) conditions.
The problem I had was sourcing a suitable non-return valve to work and fit into the ICV - so this has required a change of plan (at considerable expense to me BTW!!).
The ICV will now be mounted between the TB and compressor, as on my car.
The reason this wasn't done to begin with was because the Peugeot TB (which I wanted to retain) has a nasty breather assembly sticking out the front of it (black plastic thing with yellow connector) which would foul the ICV.
The solution now, as can be seen by the photo's, was to get a laser-cut blanking plate made up for the manifold, get a laser cut-blanking plate made for the TB (to replace that nasty breather assembly I mentioned), machine a mounting plinth for the ICV, and re-machine the MAP sensor housings to accomodate the ICV and EVAP (fuel tank ventilation) purge elbow (brass elbow ontop of housing).
Anyhow, its all been done now, will work, and looks neat. The only thing to deal with is crankcase ventilation, for which there are several options:
1. Fit beather filter to rocker cover hosetail.
2. Use oil catch tank
3. Breathe the crankcase gases back into the inlet sytem as per standard set-up.
The SC Kit will include a threaded 90 deg. 14mm plastic elbow, which can be mounted into the air-filter end plate for Option 3. This is essentially whats been done to my car, and it works well. Although I understand some people may want oil catch tanks/breather filters for the 'bling bling' effect.
The photo's show everything bar ICV ( I don't have one to hand) but I hope you can clearly see where it bolts down.
