Hereīs how the pan looked like with two of the four suctions removed.
So I'm curious, do run a vacuum pump with your 3 stage? Would a vacuum pump be necessary with a 4 stage?
No I didnīt, and it didnīt make much vacuum either.
You would have to ask each company that makes dry-sump pumps to get the correct answer.
Thereīs atleast 3 types of gears that dry sump pumps use, I think Peterson now have a twisted roots loob style also, so that makes it four typer, maybe there are more.
Most 4-stage pumps will not make vacuum that can be compared to an extra moroso vacuum pump, but a roots style dry sump pump with wider scavenge sections will pull lots of vacuum.
Georotor( moroso) and regular gear type like my old Weaver pump, will not create 15" of vacuum.
Edit: with regular gears, I meant spur gears ( googled).

Do these pumps clear the drivers side stock motor mounts and steering box mounts.? Do the dry sumps clear the steering draglink bar?

I canīt help much here, I do know of a 68 Cuda that they had a moroso 4-stage pump in, and I think it was on the driver side.
That car got a stock steering box with a draglink.
The B1 499 sat pretty high in the chassi, maybe to clear the dry sump pump ?? Car is sold and donīt know what they are using for oil system now.
Hereīs a good tech article on dry sump. The blue roots loobs are from a teflon coated Verdi pump

That article does a nice job of explaining a dry sump system. Kind of a dry sumps for dummies. Thanks for posting it.

Ya know I wonder if AndyF ever tested this on the dyno? I know he has a dry sump system and makes some parts for them, just wonder if he ever did any testing with various wet sump systems vs dry sump. Might be interesting to see exactly what is there with a good dry sump vs a good wet sump engine with a good vacuum pump on it.
The dry sump setup can certainly make more power if the engine is designed for it. The guys at Reher-Morrison claim up to 50 hp on their bracket motors and I'm not going to argue with their numbers.
Even if the power was the same there are a ton of advantages to using a dry sump. I'd recommend one on any serious race car, even on a bracket car. Not having a sump full of oil is a good reason by itself not to mention the better quality oil that gets pumped thru the engine.
I have a 3 stage pump and a 5 stage pan at the moment. One of these days I'll go ahead and buy myself a 5 stage pump.
