Pusher fans

What size pusher fans are the people who stood their radiators upright running. I'm finally starting my turbo build and will be needing some soon.

Use the biggest that will fit within the dimensions of the radiator.
Just know that pushers are never as efficient as pullers.

The turbo kit uses pushers, so I have no choice as to what to use.

If using Derales be generous with the power wire size and fuses.
Self-resetting circuit breakers work good too, they pull a lot of amps at start up but work really well.

Just checked mine, on a 100% start one fan seems to draw 30amp then almost instantly drops down to 19amps.

I have mine wired with 12awg but I soft start mine

Mine would pop the cheap 30-amp Chinese fuses on start up until I put bigger fuses in.
Also melted the I want to say 14-gauge wire if run for a while.
Once I moved up to a larger 10–12-gauge power wire and bigger 40-amp fuses, never had another problem.

Those Derale fans are garbage at best. Lots of failures.

Mine worked fine for over four years.
I think there's more to it than just the fans.
Have you seen how people wire things up when left to their own devises?

I had mine wired up mint. Heavy 10 awg wire, auto reset 40 amp breakers and in the end the windings inside the motors just came apart. Even China would be embarrassed by those things

Wasn't insinuating yours weren't wired correctly, you may have just gotten a bad batch.
A lot of guys swear by them but it's like anything else, you pump out a million a year and there's bound to be lemons.
