Cooling Fan Insallation and Analysis.

Just what it looks like, a diagram of the factory subframe from a 1967-1969 Chevrolet Camaro.

Looking to replace your belt driven engine fan with an electric fan in order to free up some horsepower? Do not underestimate the importance of having your electric fans properly wired and controlled. A wonderful product that will drastically simplify the process is the Delta Current Control Module.

I recently replaced a 7-blade thermal clutch fan on my 1966 Malibu with a dual 13″ Derale setup. The dual fans draw a massive 50 amps when turned on, but move an impressive 4000 CFM of air. Your car does not always need 4000 CFM of airflow in fact often it will need little to no fan assistance to stay within operating temperature. This is where a fan controller comes into play.

A typical electric fan install consists of a thermal switch that operates a relay. The relay is in turn connected to the fan. Often the thermal switch will turn the fan on at one temperature, for example 210 degrees and off at another, say 175 degrees. The problem with this sort of setup is that your engine temperature is constantly fluctuating.

The Delta Current Control Module operates by varying fan speed to maintain engine temperature at a desired level. The unit is a full, self-contained system. It takes the place of a thermal switch, relay, fuse, manual override switch, air conditioning switch, etc. [Read my article on the Install of a DCC unit in my 1966 Chevelle.]

I have been running a DCC unit on my car for the past week and once car is warmed up the temperature gauge rarely moves at all. This includes a 100-mile freeway drive, multiple drive-thru lines, a trip to the drag strip at LACR and a 30-minute driveway idle. The switch from mechanical to electric fans has also freed up a noticeable amount of power.

Features:

1. Turns on fan only when needed
2. 100% Self Contained, compact Unit
3. Adjustable Target Temperature (148, 158, 166, 173, 180, 187, 194, 202, 212)
4. Maintains engine Temperature within a tight heat range
5. Has provision for A/C activation and use with under drive pulleys
6. Choice of two types of thermal probe
7. Frees up horsepower (verified by my faster quarter miles times)
8. Can also be used to control an electric water pump.

Verdict:

A no headaches solution to electric fan control. The DCC unit is an elegant solution that works as advertised.

SEMA Drifting Article

The drifting scene is growing by leaps and bounds here in the United States. After an initial demo at Irwindale in 2003 drew record crowds and two years of Formula D competition, drifting has a large and growing following.

I have decided to add a Drift only site to the Hot Rod Homepage Network after attending the last several events of the 2005 Formula D season as well as numerous DriftDay and JustDrift events. The DriftLive site is very much “under construction,” but will be at 100% by the opening of the 2006 season in Long Beach, CA on April 2nd.

Give Drift Live a look.

Not into drifting?
Take a look at the Team Falken 1969 Camaro ripping it up.

The server that hosts this website has recently undergone a massive upgrade in the bandwidth that I am allowed each month. Because of this I was able to add a video gallery to the Hot Rod Homepage. I will be adding more videos as I have time, but for now there are a few videos of the 1969 Camaro that Ryan Hampton drove at the last two Formula D events of the 2005 season.
