V8 Radiator Sources Options

[kyracedog]

Ok V8 guys, what type of radiators did you use? I know Renegade sells a kit that works, but $1100 is a budget buster. Already have the dual fans to use, so don't need them.

Looking for ideas/suggestions/sources.
Thanks.

100 Amps sounded way too high, so I Googled it and found the following where the article claims that Mk VIII fan draws only 30 Amps (though it doesn't say anything about startup current, but I can't imagine it being more than 3 times higher).

The 30 Amp requirement will not require all those expensive bits. You can buy 30, 40, or 60 (or higher) Amp automotive relays here:

Hey Andy,

As you know, I'm a sales guy in the power electronics world and have learned the start-up inductive load for electric motors can go as high as 6 times normal running current. However, there are a lot of variable, starting with the motor design, wire gauge, operating RPM, the Length of time the Peak current is drawn, etc. There are Slo-Blow fuses available designed to ride-through the current peaks to avoid nuisance "blows", but I have not seen them to be readily available.

If the fan is ACTUALLY rated at 30 Amps constant running, rather than "Rated to 30 Amps", I would go with your suggestion of using 60 amp relays and 60 amp circuit breakers from wiring products.

Best,
Terryu
