Red face SPAL 2700 CFM electric fan

Hello,

Do you think a SPAL 2700 CFM dual 11" electric fan / alum. rad. combo is sufficient for a 400 HP engine and street use ?

Thanks

I have a dual spal electric fan (can't remember how big) and aluminum radiator on my 408ci BBC and have had absolutely no problems whatsoever with overheating. I don't know the hp I have but I would guess it to be 400+. Spal is pricey but I would recommend them if you have the money.

only thing i'd be concerned about is how well the fan is shrouded, to produce proper flow across the rad. Also, are you using a manual or automatic transmission. if you have an automatic tranny and a big stall converter, that's gonna produce some extra heat. 2700 cfm is pretty hefty though.

good luck

You make a good point blndweasel about the shrouding, xmsn type and stall speed. The fan pkg I bought consisted of the two fans, shrouding, relays, etc. It included almost everything necessary to wire and mount the fans. The fans came mounted side by side in a shroud that can be placed directly on the radiator and do an excellent job of shrouding the air. I made my own brackets to mount the fan pkg. Also, I'm am running a TH350 with a 3600rpm stall speed and external B&M tranny cooler on the front of the radiator. I have yet to check the trans temp but I haven't seen the engine touch over 195 using a 180 thermostat in August.
