Recently finished hot rodding my 50 Ford F2 with original block. It has a Magnuson supercharger with two 94 carbs. Due to the manifold required by the supercharger, I lost the vent tube. Any suggestions on how to adequately vent the engine?
Jeez, that is about the meanest F2 engine I've seen so far.
Speaking of ventilation: Are you shure those tiny air filters have a good flow rate? Often they are a little obstructed, at least they push the air around some very narrow corners.
Would be a shame if this nice engine could not breathe to its fullest…..
According the engine builder they are good, as he has built many flatheads using that set up. The engine is a very strong running flathead even though it's not "max'd out". It's set up to run about 5 lbs boost with a 3/4 cam
I got the entire setup as a kit from TR Designs and your photo is from his website. It appears that that manifold is too tall and would have not allowed the two carbs to fit under the stock hood. I have sent Tom at TR asking for clarification. I bought the kit and had it sent directly to the engine builder. The attached photo shows the system the builder came up with to add oil. It works great.
I wondered what that can was for. I think you'll have to use the same connection for venting, in fact drawing off the side of the can with a PCV valve would give you an oil separator, which is good. What does the hose out of the can connect to? Is there no plug at the front of your manifold?

That's exactly what I was thinking. figured I could fabricate a Y fitting to go into the oil fill line and branch off with a breather tube. The hose from the "can" connects to the inlet side of the oil passage on the back of the block.
I got a reply from Tom Roberts ref the manifold in your attached photo. That is an intercooler manifold made for racing for superchargers running 15-20 lbs boost. I'm running about 5 lbs as I would like the engine to last. Moreover, it taller than the one I'm using, which only has about 3/4 inch clearance between the hood.

Not sure what you mean by "inlet side passage", if you mean the one going to the bypass filter, that is under full oil pressure. Both of the connections on the back of the block (near the bellhousing) are under full pressure. I would be surprised if the can is designed to withstand that. And it would not work at all for a breather.
Unless you want to pull the blower and manifold off to make a connection into the valve chest, your only other option is to draw off the side of the oil pan. The very first flat V8s did that, not hugely successful tho. Sucking in oil would be very likely.
Thanks for your excellent replies. Im really discouraged. There is an engineering flaw in the intake manifold for the Magnuson SC.
"inlet side passage" was told me by the builder of the engine. I don't know what the official title of it is, but it sounds like that is not an option.
Can you tell me what this is, in the red circle? And where does the hose go from the manifold, with the red arrow?
I find it difficult to believe a professional engine builder would put together a blower motor with no provision for crankcase ventilation. What does he say about that?
