Never said you were an idiot...in fact I posted the opposite earlier on. No need for salt , sarcasm and jest can sometimes not roll out right in text (Apologies).Your recommendations don't appear to be based on reading @sikryd's actual problem.
@sikryd already has electric fans.. 2730cfm if I'm looking at the right model.
He indicated lack of funds was a major problem and that he did not want to upgrade his current fans to the latest greatest electrics. That's one of the reasons I made the recommendation to take what seems like a step backwards and go old school, just for cheap cfm. I'm not recommending old tech just to be a contrarian. I might not be a complete idiot.
To repeat myself ad nauseum, yes mechanical fans use more power at high rpms when pushed out of their efficiency curve. Absolutely nobody is trying to say any different. The actual problem however is "how do I cool my car?", not "how do I save 20hp at 7000rpm?". He's not drag racing the thing, but apparently wouldn't mind being able to drive it without it overheating.
I already recommended changing that out, it wasn't an option he wanted to go with.
Glad you found it entertaining. I'm not defending antiquated tech just to be a contrarian. My advice is based on actually reading the thread and trying to understand the problem and the constraints @sikryd is working with.
With all due respect, if you're trying to help, I recommend actually reading what's already been discussed. Some of the discussion and recommendations might make sense to you then. I might not be a total idiot popping off with a backwards idea for no reason. I like new tech. I like electric fans.
"It's not a hard problem" and "it's not longer entertaining" is pretty condescending coming from someone who apparently hasn't read @sikryds posts before implying the recommendation is idiotic.
I guess "It's not a hard problem" if you haven't bothered reading it and just want to pop off with generic advice like "buy $$$$ electrics you can't afford, because they're always better for every situation, always". Yeah, that was pretty easy.
Again, high dollar cooling systems are not in the budget, hence my recommendation for cheap old crap that works really good, at the expense of some power up top of course.
I'm sure the SY/TY guys know all about cooling constraints, but by now you hopefully know the constraints we're dealing with are completely different. Also, do you think a FI 4.3L V6 (even a hot one) might just dump a little less waste heat in to the cooling system than a carb'ed big block chevy? Oh yeah, and the Sy/Ty platform has a whole bunch more rad surface area than a tri-five..
So yeah, in summary @sikryd could probably go nuts and get a $$$ better radiator, $$$ better electric fans etc. I'll absolutely concede that would be a more elegant solution. But, actually paying attention, he said money was tight, which is why I recommended going back to the stone age with a simple shrouded mechanical clutch fan. It's old tech, inefficient power wise at higher rpms, but you can't beat the cfm per dollar.
But hey, if you have a wiser solution that will double the CFMs for probably under $200, I'm sure @sikryd would like to know about it.
Sorry if I come off a bit salty, but you rubbed me the wrong way implying I'm a fool when you haven't even attempted to read and understand the problem before implying I'm an idiot and offering your own unhelpful advice as the definitive answer.
