All Small Six Pinto 2 blade fan on 200

[clochard68]

Has anyone mounted a Pinto 2 blade fan onto a 200 waterpump? Do the blades have the same diameter?


Reason:
I am planing on getting a little bit more horsepower out of my already mildly modified 200.
For now the plan is to get rid of my current high flow water pump and switch from the standard 4 blade mechanical fan to a 2 blade mechanical fan, both to achieve less parasitic loss.
Overheating was not a problem until now even in the summer sitting in traffic, and electric fans are not an option for my car (it has to stay in more or less original state, my car is registered as a "classic" car in my country and the law is very strict regarding modifications).

I don’t even remember ever seeing a two blade fan here. I had a 74(I think) pinto squire. 2300 engine. My first car

Why do you "need" the extra HP? Drag racer, or street guy? A cool engine is way more important than 5 hp

Is there any reason why you’d not want to have an electric fan? I switched to an electric fan and I find it cools better than the 6 blade fan I had on mine. I notice that my car idles better without dragging the fan around too. It’s connected to a temp sensor that switches a relay AND I can override it with a toggle switch in my dash if I need to turn it on manually.

I picked up a 16” and it is ever so slightly too deep to fit between the radiator and the water pump pulley so I have fitted it in front as a pusher fan. I considered moving the radiator forward 1/2” so I could install it as a puller but it does cool very well as a pusher fan. If I were to do it again, I would find that 2-fan setup from a Ford Contour or one of the similar setups so that I could put it all in the engine bay.

EDIT
This one on Amazon would be what I’d look at next time. My existing 16” has 2600 CFM and this one has 2500 CFM: https://www.amazon.com/Enignelooc-Aluminum-Radiator-1963-1970-Fairlane/dp/B0BKKJY81Q

@wme013 you are right, a cool engine is important! In fact I don't have overheating problems with the ebgine right now, and from what I've read and seen depending on the fan it can rob up to 20hp, that is quite a lot.

@awasson I am not allowed to install electric fans in my car, by law it has to be basically period correct, has something to do with insurance...

Right. After I get the bodywork done (it has had the roof replaced and need to be repainted) I’m going to see if I can get collector plates and reduced insurance for mine. Both of my motorcycles have collector plates and it costs a fraction of what regular insurance would cost. I think I might have a hard time getting collector insurance on mine with the adjustments I’m made.

No, you wouldn’t have a hard time. With Hagerty all you need to do it have another daily driver and keep it in the garage. You can set the value of it too

Thanks. Great tip. I was pondering that too. My insurance comes up in the spring so I was thinking of checking in with them. I know an old primary school friend is with them so I’ll be reaching out to him about that.
