Shaker hood and electric fans

[4Cruizn]

I was wondering if anyone here is running a shaker hood with electric fans.  I think I am having a heat problem with this combo and wondered if anyone else has issues?

Heat problem how? Rad overheating or carb boiling the fuel? I ask as I have the HHR fan, works great but in traffic in very hot weather I have trouble with fuel boiling. I have a rendition of the 6 pack air cleaner and it really traps the heat around the carb. It has never stalled or let me down or stranded. I can tell right away and I rev up the engine to clear it out. Once I'm moving again it's fine. I imagine one could have the same issues with the shaker set up too?

Yes this is the problem I believe.  The shaker just retains to much heat and without the fan moving all the time, I think the fuel in boiling at the carb and then the car seems to misfire a lot.  The hotter it gets, the more it misfires.  The actual engine temp is fine . . . 

Does rubber fuel line withstand heat more than a metal one?   I would think so but not sure it will help enough .. .

I had a 240Z that would develop fuel problems related to heat, some improvement was realized from putting foil covered insulation around the fuel lines.

How about modifying something like a power steering cooler to fit over the fuel line?

an alum heat reflecting plate under the carb could help

I think selling the shaker assy to me would be the quickest and cheapest fix. 

Sorry, couldn't resist. But it is an option...

4C , I run an electric fan as a suppliment. Thermostatically controlled. It helped lots in slow traffic on hot days!

Agreed, the shaker holds TONS of HEAT!

circle track racers use this and some ducting aimed at the carb bowls to get rid of heat. It would help but it would look kinda ugly/out of place?

The other consideration is air flow Out of the engine compartment , we installed a killer 340 in a D50 pick up & it ran hot until we opened up the hood to allow more airflow out , this should not be a problem with what is essentialy a factory set up & I am not recommending cutting holes in the hood .

Two thoughts.  I used to take the cloth wrapped (German) fuel hose with ID the same as the OD of my factory metal gas lines, slit it lengthwise and wrap it around the entire length of the metal lines.  Rather like the foam tubes they sell at hardware stores for water pipes.  It did help.


Second... could you get a second temperature sensor (ambient or air temp) and wire it in parallel with your coolant fan sensor so it could also activate the electric fans (by activating the relay)?  I'd bet there are units with an adjustable temp setting available so you could determine and set the 'sweet spot'.
