I am thinking I will install the supercharger and get it running thru the 3", then add the smog piece, then depending on the timing, head down to the VASS guy shortly afterwards. I asked the VASS guy what he wanted to see and the smog device was all he mentioned. If he wants a drive by I will see if i can take it easy, but mine is pretty quiet now. I will have had enough of the car by then I reckon, so will probably park it up. Bit unsure where I will be with work as well, could well be interstate for the first 4 - 5 months of 2019, so just have to play it by ear. Parts dont arrive until the 3rd week of jan at this stage. Post that I will open it up to 4" after the smog device - unsure who will do this at the moment.

Greg from BD is getting his pump guy to do a WOT flow test on the big pump either wedor thursday, so we will know what the flowrate needs to be for the pump volume no later than friday.

I hear what you are saying, I'm leaning towards the Airdog solution, so comparative data might be available between us down the road.

Here is the de-aeration filter kit recommended by AirDog this morning, just for comparison with what you are looking at. 165 4G Kit A6SABC108

The e-mail I got from airdog recommended the 100 kit, but more than likely, if I do go airdog, I'll go the 165.

FASS came back this morning also with this model for comparison, TD02 095G

Regards lift pump pressure and flowrate, here is what they said, which is aligning with the over supply statement you made in an earlier post re pump pressure.

We will normally flow quite a bit more than the injection pump. This will allow us to maintain full pressure even at WOT. We normally try to get a horsepower rating of the engine or a required flow rate for the injection pump to determine which FASS pump flow rate will work best for you. If you are looking to run about 200RWKW then I would recommend a T D02 095G Titanium Series for a 89-93 Dodge. A 95G would support approximately 450RWKW. The T D02 kit would be the closest match to your application

Smog device arrived today - there is no way its going to stay as supplied, its simply so dense that the engine is going to choke. Its the 200 cell/inch unit as required by the VASS engineer.

Flange it, run it, have it pass, then ditch it.....

Yep, bought 3 sets of flanges just for that. It would be like trying to exhaust thru a pillow

Ordered the pump today, 440lphr, 14 psi. Got a spare as well. Started reading the forums in USA, alarm bells at anything over about 25psi it seemed, but that might have been from electronics? Anyway, seemed that a precharge of a couple of PSI at WOT, up to 5PSI was a 'norm' and gave good performance and reliability. Still waiting on BD advice, simply gave up and based the selection on the avail flowrates.

Learning here with great interest good blokes!
Can only put forward that I now do believe when my old GU6.5NA gets beyond say 45 degrees upskis mountains that her lift pump must be undersized?
Quite the freaky experience when they suck air I guess and powerband beyond our control totally losing traction experienced:-(

I have proven the Brunswick installed lift pump I'd too small from a flow and pressure perspective , so even for the n/a version, consider the Aerofloat "blue" fuel pump. It's rated at 440 lphr at 14psi and is the one I am upgrading to for the s/c. This pump is used by another guy with the same coho as mine will be and he has 70000klm under his belt with it. They are about $100 delivered and common supply ex Aussie. You can go to many other variants and costs but there seems to be a lot of pumps avail at this spec and also at slightly higher flowrate and pressure in the 20 to 25psi band as well
