Cooling fans + Shroud

Space is tight ..

Show me what you have , I'd like to drive mine just a little on the street

I can't tell you how well this would do in your environment but it's worked for me. I feel a tight fit around the fan and shroud (i have rubberized foam around the seams) is important to draw thru the core area.

Rereading your post, I still like the security of a belt driven pump on the street. You can use the old moroso motor and slip the 'v' off and the cog on for track use. Which I like to circulate coolant after i shut off the engine, especially on a BBM with IRON heads.

? ? ? ? ?

I have very little clearance and I went with a Delta Pag 18" 4000CFM last year. It comes with a controller to adjust the speed and temp on and off settings. I have it set at half speed then full speed at a certain temp. On drag week this year we took two hours to go 17ish miles. Every temp creeped the whole time but never got over 205, trans was almost 200, and fuel was like 140! I am probably glad I don't have an oil temp gauge.

It is also brushless and soft start, I want to say this one draws 26 amps at full speed.

LOL one of my fav meme. Sorry, the same pic is in the "who for carb building" thread in this "race tech" forum must be a higher resolution issue? But you can see how tight things were.

From pump to radiator , I have 1-1/2 inch , I can use double 8 inch ones that are 2400 CFM ..

Or suppose I could use a pusher too ?

pia

tight fit

Since am spending your money here why don't you move to a remote mounted pump and use one fan. Its only money haha.

The controller they have will control two fans, so that helps with the cost of buying two. I am sure if you could make a shroud that cleared the pump two of those fans would be more than adequate.

I am going to try my gimmick and see if it works

I think I could run 4 if needed too

I use 2 Spal 12” fans with 1640cfm each. Cools my 12.5:1 511 with a tall fill just fine on city streets, but not so good on the freeway at 65-70 mph. My system only holds 2 gallons of coolant.

I have the shrouded dual spal fans on my Challenger, never runs hot.

2000 Ford Countour fans fit a 26" Radiator. The center between fans is thin.

I use a single 17” 2-speed Derale fan and shroud combo that fits my Summit radiator like a glove. I have it set up on a temp switch to come on at 165 and shut off at 150. Fan runs on the high speed when the engine (and alternator) is running, and the low speed when the ignition is off for the lower amp draw. The “key off” circuit also includes the water pump.

My car sees regular race duty and a few cruise miles in the summer, which means idling in traffic in warm to hot temps. I’ve never seen it over 200 since going to this setup.
