What brand of water wetter, if any, are you all using? Where can I buy it? How much do I use? Does it help much at all? I've heard it eating at the aluminum radiator.

We put in our most powerful motor that we have ever had (more power - more heat) 2 weeks ago and keep having some heating problems with it. NEVER had problems before. Raised the jets to 98 and 99, put a 180 degree thermostat in it. Running Valvoline Racing Oil (20w-50) with 1 quart of Lucas Oil Treatment. Temperature is right around 200 on the track. Temp rises fast to 235 by the time I make it to the pit stall.

Running on alcohol with fan about 2 inches away from the radiator, no shroud.

Any ideas?

Thanks in advance!

if your not running a shroud, get that fan within an inch of the radiator that'll cool it down
i use "Water Wetter" brand water wetter
its pink in color

a cap full of downy is what i put in along with distilled water.

There are numerous things that you can do to help cooling. 1-1 pulleys, higher pitch fan, NO themostat.

I would take that thermostat out first and build a shroud, that'll definitly help.

We have used both 'water wetter' and royal purples 'purple ice'. I dont know how much difference they make but both have anticorrosion/lubrication properties that i feel are the biggest benefit.

What kind/size radiator are you running? What kind of carb are you running? What do your plugs look like? On alky you shouldnt be having any trouble keeping it cool. Check your raditator and make sure it is clean and you can see thru it. I know on gas this year if we dont clean the radiator out after a heat race it will run 20 degrees hotter in a feature.

Really 200 on the track is about ideal, all engines will climb a little when you first bring them in to the pits. If you were running 235 on the track would be a different story.

Thanks for the replies.

I agree with everyone about the track temperature. The engine builder said that if we could get it to run at 195 on the track, that is ideal. The only problem I am seeing is the way the temp rises on the way to the pit stall. It goes up quick and doesn't cool down to fast if I don't pour water on the radiator. If I'm not careful, by the time the feature rolls around it will still be too warm from the heat race run ( the shows here have been running really quick without intermission because of the threat of rain just about every weekend thus far ).

The radiator is 22wide by 20tall. We are running a steel 5 blade fan. About the thermostat, it seems like it is a LONG ongoing discussion as to whether the water temperature will be hotter, cooler, or remain the same with a thermostat. The one we have in is gutted.

I have not added any holes to the nose to help cool it down because I think we are really close to on track temp.

The engine builder suggested that I rev the engine (not wild or anything) a few times as I'm coasting down the back stretch to come into the pits. He said this will put some fuel into the secondaries and help out some. He also mentioned something about running some type of hose on our intake. I am pretty certain this intake is a Victor Jr. It has two holes that are blocked off with fittings. Supposedly, we can run a hose between these two holes with the proper hardware and it will make the engine run cooler. I can't say that I understand this ideal really.

I have the radiator soaking right now to see if that will help any. I'm going to put some water wetter in and see what happens I guess. A shroud would be ideal I suppose, I was just trying to get away from having to make/design one.

Good Luck to all this weekend,

I'm not an engine guy by any means, matter of fact I tend to leave that to the experts, but the hose thing you're talking about I believe runs from the base of the water neck housing on the intake to the center of the intake for extra cooling for the middle cylinders of the engine. I have a 358 w/aluminum heads, brodix intake that has these hoses on it. I run an afco high pitch 5 blade fan, about 1 inch from the rad, no shroud, with a thermostat (180). Most of the time I can't get the thing to warm up quick enough. Can't remember for sure, but I think it runs in the 180-190 range during the feature (7500). BTW I run alky also.

Stewart water pumps says they have tested wetting agents and other than lubrication benefits there is no cooling benefit, according to their website. I run alcohol without a fan no holes in nose in 98 degree weather and run 200 or 210 under race conditions. Under caution the temp will go up to 230 if I am behind someone close. Light goes out when pull out and get clean air. Goes back down to 200-210 when racing

What is the fuel pressure doing?

when temp goes up like that and stays there it is usually an air pocket. be sure to get all the air out of the system. You also need to check the carb or jetting- cool is the reason that many run alcohol.

Everything I have added a shroud to has lost 15 or more degrees so I would start there. Also have seen where a higher intake raised the upper hose above the radiator fill cap and created an air pocket. Cure that by extending the thermostat housing upwards or jack the car up to fill it with water which is a real pain. But on the track is ok so I wouldn't think that is a problem. We run a windshield washer pump and small jug of water to build a mist system to cool it down on the way back to the pits. Just fill the jug before you go racing and your set.

We run water wetter and it has dropped the temp. 5 - 10 deg. on gas. We use a restrictor in the thermo housing.We run water lines from the back of the intake to the thermostat housing. These are return lines, and they get the air out of the motor. And we run lines from the water pump to the middle of the heads for better cooling
1 - 1 pulleys. And we run about 190. (until we start leaking) Rad 3 wks. ago. Water pump last weekwnd
