main rad fan cfm rate, data needed

[GazzaG60]

corrado engine was a supercharged 8v running a 65mm pulley. its warmer than an s2 engine with a radiator about 1/2 the size.

the shroud is worth about 30% IIRC. without it you cool one spot. the pacet will run at similar noise but flow more air.

what makes you think that an S2 will be hotter or more powerful?

ive already been down this road and know it works. im thinking of doing the same as now my fan is drawing a little to heavy and it can be felt when it kicks in.

decide whether you want a puller or pusher. IIRC pusher is more efficient. 1168cfm would suck a rag to the front of the rad pulling through it.

cfm will be quite high.

i looked into replacing mine if thats what you are after.

IIRC the correct size is the 12" pacet pro to be able to make it fit into the shroud. ive used one before on the corrado it was 1668cfm. expect them to be 1200-1600cfrm or so. id go for about 900-1200 for the factory mamouth.

Sure about 1600 cfm? i mean corrado's engine's less powerful and much "colder" as it's a naturally aspirated one.

Which fan? THE ABY / RS2 fan is 500 watts AFAIK

thanks, Jamo, for your quick reply, a 3B fan to be precise. Is it of any difference with ABY?

Hi there! help needed desperately. Original main rad fan airflow CFM rate, anyone? Or at least amps draw of the motor?

Thanks in advance,
Mike
