I was told by a tech person at a local track after my car overheated in a heat race that a cup or a cap, I can't remember how much of liquid fabric softner in your radiator will make your car run 10-15 degrees cooler. Anyone ever tried this?

I agree with 17j on this

find why it is having probs 1st
probably just a simple reason/fix
then if ya still need a band aid

the type of fab softener the guys around my neck of the woods use ultra downy 2 caps full

I have mine running so cool w/just water (I add the water conditioners just to keep the water from rusting ) I had to add a t-stat just to get it to warm up to a comfy operating temp

I'm in the same boat not building enough power to over heat lol. Got the fix for that this week though.

We had a problem over heating first night out.

I cut holes in the aftermarket nose, added a front air dam, and installed a thermostat( a lot of people will tell you not to run the thermo, you can just run a restrictor).

That fixed our heating problem.

Thanks guys I am running a restrictor, a stock rochester 2 barrel. I had a guy tell me last night my fan was too far from the radiator also

A secret I have is to make sure the shroud is sealed the radiator with high-temp tape. Air takes the path of least reisitance so make sure that the fan is pulling air THROUGH the radiator not from it. I also sealed the front of the radiator to the opening in the grille by making a tunnel with some plastic. I hope these couple things help.

What I did on my intake was make a water bypass for the rear ports on the head and routed them to a thermostat housing that had two places where I plumbed a line in from each side. (the back on all stock chevy intakes have no water passages through them. If you see an aftermaket aluminum intake, they have bosses machined there so you can plumb your own) The water kinda sits in the back of the heads and doesnt circulate very efficiently. This set up alllows the water to circulate better.
Speedway motors sells a kit that says its for a stock intake but, it will not work. Their adapter hits the intake where the carb bolts up. They say this setup will knock about 20 degrees off of your total. I have never had any problem running a 28" racing radiator and the intake bypass system.
