Probably hard to see, but this really neat ‘32 has a newer Eato supercharger. The guy sealed the stock rear intake, made his own top mounted carb base with 2 Strombergs. It’s a VERY slick little car, has a finned aluminum oil pan, and heads with water jackets, which I’ve never seen. Also removed some material from the base, made his own drive snout and some other things to make it look more “antique-y.” Slick.
I like to see the Bearing / suport . Even with Plastic fan that shaft is long. Like to know how much weight , force leverage on end @ fan in relationship to bearing. Wonder if engine stay's below 3,500 rpms
10 3/8" on an M90. That was a "prototyping" snout. Came real long, cut to length and bore for the bearing. The plan was to cast snouts with enough ribbing for the length. They could do it $$ I needed the PS mount anyhow, this was how I built them. I don't see anything out by the pulley end of the blower snout. That also looks like a tubular snout. Maybe if it were beefy enough tube (the shaft is small) The fan drive does look sketchy. BTW, we turned the blower near 16000 rpm at redline (5250 limiter). IDK the ratio there, That would be scary at rpm.
Kind of like this? https://www.jalopyjournal.com/forum/threads/flathead-build-with-eaton-m112-blower.1105147/
@AccurateMike when sliding blowers back & snouts became long we would make up snout support ,griddle . When using a screw with carbs ,I have No testing with. Does it feed cylinders evenly? I would not think so screw with carbs , Roots even on mild set up rear cylinders Lean compare to front ,little tricks can be done to solve with carbs fueling ,, MFI ,EFI you can add fuel as needed on each cylinder. So on screw with carbs whats going on with fuel distribution & AFR's per bank? Casting , I would of like to learned Sand casting , do not know any place local , nor can not find some one with Decent 3d printing
Very similar to that one. Eaton made several versions of this M90 style. The adapted drive was engineered by Bob Whitehead well known flat head guru and Ardun expert, it worked well, but I did not like the aesthetics of the adapted components, I cut off the unnecessary mounting bosses and casting webbing to clean up the case and created additional vertical fins where I could from the pruned cast bosses. I did not like the idea of running an electric fan on this car, so I had this fan adaptor machined. There are entertaining comments from photos, that is why I post very little these days. The mechanical fan mount is not a tube, it is a solid machined aluminum adaptor I had tapered to reduce as much weight as possible, at one end it is bored and tapped to replace the retainer nut for the pulley and safety wired due to blower shaft the rotation. I found a black plastic (Yes not traditional, but I prioritized light weight) fan that is very light weight, it has been working fine so far, but I have not had the car running too long. If I have problems and it breaks, I will just change it and fix it. That is what hot rodding is about to me. Here are a couple of photos to help the guys that had questions.
@Chopt 34 I think this way , make part's , I am not a Engineer.. just was curious fan extension on How long & how much flex & pressure , balance on fan end that fair away as fan pulls air ... I just thinking wonder what a Run out gauge with a wheel would Tell you as engine speed increased . Do you have any data , screw with carbs Cylinder AFR balance inside the intake?
Thanks for chiming in and explaining how you pulled this off. I wished I’d taken detailed photos of the car, and hav talked to you rather than eve’s dropping while you talked with Mike, I’ll make sure to the next time. And I totally get your hesitation to share things here, ther are always experts ready to tell you how you should’ve built your car.
Sure thing Brian. BTW, I appreciate your post. Now that you are back in Florida, I will try driving up to the next Cars & Coffee in Sarasota where we first briefly met last year.
It is a really net little baby blower. Just do not think it would justify itself in performance with all the work and $ that went into it. Fairground cruiser? Couple times out a year?
