what your cooling tip?

[Dirtrunner35]

Best 3 hours I ever spent, was to make like a air dam under the front bumper to the radiator. The sides went to the bumper and the top of the radiator sloped down along the bumper to the bottom. Never had anymore holes in the front bumper. Came off the track at 200. Stock water pump.

has anyone ever used one of the SBC cooling units to help get cooler water to the heads?

go to washromm and take bath

I Run those extra cooling lines, but not like most do. I see many cars going from back on intake, up then forward then down into front of intake. I run them into a T into the water neck, so they never go back down. I don't like leaving an unventable high point.

Hope that made since.

yeah. speedway motors sells a kit that does exactly what you said.

we had a fan bolt break 2 weeks ago and it destroy out shroud and beat up the fan pretty good. we ordered a new afco fan...17 1/2"....and when we got it we noticed just by eye ballin' it that 2 of the blades were longer than the others. one side was 17 13/16ths and the other side was 17 5/8s. because of this the fan would not clear the rack. we ended up taking it to the grinder and making them both 17 1/2. has anyone ever noticed this or is it just us that has had this problem? it was an afco fan that was brand new out of the box.

I tried that same setup speedway sells on a stock cast intake a few years ago. I sent it back to them because the lines that come out of the aluminm plate run directly into the runners of the intake. So depending on what style of intake you use it may or may not work. What i ended up doing was drilling and tapping the intake by the back water passage in the back of the head and getting a therostat housing that had two hole in it for different sensors and then just get the adapters to make the fittings work. If i recall the lines were only 5/16" I.D. Im my opnion this isnt very much water moving in the head to make that much of a difference. If you can run larger lines it would be better. Most of the aftermart race aluminum intakes have much much larger fittings to run #8 line.

we dont run one and personally and never have, but i have heard that some people have success with them. this last week was the hottest its been out and we ran right around 195 after the feature. it was a slick track so that is cooler than we will be if we run a heavy hammer down track, but i would only expect to see temps of around 210 on a night like that. which should be no problem at all. the guy that pits next to us runs a stock car and he pulls off the track and has 2 people waiting for him with water tanks to hose down the radiator...he said that he hits 250-60 every feature. lol thats with a molded monte nose piece that basically has the entire front of it cut out for air flow and a pretty darn good cooling system.....could be that he is running a ford motor though

Alcohol

I heard if you put some alcohol in your radiator it will help keep your water temp down, never done it myself, but have seen a few people do it.

It would be gone the first time the engine got up to temprature.

Straight water, with a little rust inhibitor, or just a couple drops of oil, going through a clean radiator has always served me well. And using a four blade fan.

[Egoracing]

Stewarts told us straight water and Prestone Rust Inhibitor for pump lube and protection. Said many NASCAR teams are using the same thing and it worked great.

Water Temp

Distilled Water will help also..

[Egoracing]

Distilled Water will help also..

If you are running a virgin aluminum block and all new stuff it will but if you are running a cast iron block or heads there is enough impurities that will get into the water that it removes the benefits as soon as you put it in. The reason Distilled works is that it is pure and will not boil. Once you introduce anything that will suspend in the water it's boiling point is back to the same place as regular water. The only other benefit it has is you are not adding any minerals or salts to the system. If you have hard water it is the best way to go, if you have good filtered water it is as good and will save you some money.

we just run water right out of the garden hose hose. never had a problem. we do have a pretty strict regimen of cleaning the rad and flushing the entire system on a regular basis and i think that helps also.

another thing that i think is really overlooked is good hoses. when we ran hobby stocks years ago we just ran plain jane stock hoses and always had trouble with them. its worth it to invest in a good set of hoses with the wire in them to keep them from collapsing in a bad scenario.

hmm..last i checked pure (distilled) water boils at 212 degrees at sea level. maybe my physics teacher in HS was wrong? lol
