Default Biggest size pusher fans on 240 condensers

what is the biggest single pusher fan you can get in front of a 240 condenser without taking the whole front apart?

I have 2 little 12in chinese ones right now, they work, but are loud and vibrate the whole car, was thinking of getting a high cfm spal

I used a 16" SPAL as pusher fan. You can use a ballast resistor not to run it at full speed- this way it will not be too loud.

did you use any dampening bushings when mounting it to the condenser

Yes, some foam pads and hose over the round zip ties that came with the fan but I don't recommend any of that - just make normal brackets that hold the fan close to the condenser. Over time the vibration will wear the pads or bushings and the fan will start getting loose and may damage the condenser.

The cheap price chinese fans are hard to pass up, but you take the chance of a fan that doesn't last or in your case one of them is vibrating. Dump the bad one or buy a better brand.
Spal fans generally last a long, long time and run very smooth, but of course much more money. I've used both and I've seen cheap fans fail after simple wet weather. Never had one vibrate though.

I have two 12" pusher fans on my V8 wagon. Took off the shrouds and made custom mounts, never had a problem with over heating since I built the car 33 years ago.

good to know that a fan vibration, albeit from a cheap chinese fan is not normal

The stock 240 pusher fans are about as good as you could find, and the stock hardware that mounts it in front of the condenser have vibration isolation bushings on three small brackets, I believe they are 14" and run off a 20 amp relay, so if you use one up the alt to accomodate the increased load. These are on 90-93 240's
