Now that summer has hit and local fuel has gone to a greater ethanol content, my car is starting to have percolation and vapor lock stalling when it sits after a long run. Having attended a show last weekend, a number of other folks reported similar issues with their carbureted cars. Has anyone had any luck with a specific additive to raise the fuel boiling point or used any of the carburetor heat shielding blocks with success? As you know with a '40 there isn't much clearance between the top of the air cleaner and the rear glass (I have 3/4 of an inch) so the big phenolic blocks aren't really an option. ]]> Veek http://www.gt40s.com/forum/gt40-tech-fueling-electrics-engine-cooling/40488-carb-percolation-vapor-lock.html 12V To The Radiator Fans http://www.gt40s.com/forum/gt40-tech-fueling-electrics-engine-cooling/40472-12v-radiator-fans.html Sun, 16 Jun 2013 16:52:34 GMT In an attempt to diagnose my Lucas radiator fans not operating I'm wondering this: There are two wires, black & red, coming off the fan. For testing purpose, I attached 12V power supply to the red wire and when I put a test light on the black wire I have 12V power there too. I'm assuming that's not right, is the fan defective?

I am going to do further test on the relay as well because I'm not getting power to the fans at all when connected to the proper plugs. Seems to me this power source issue may be related to the defective fans.

Hi all

I am going to have a go at painting the end of my copper radiator pipes today and wondered what type of spray paint and primer I should use. Do I need to use high temperature paint or will regular automotive spray paint work as I am not sure how hot these pipes get?

Thanks

We have found out that the heavy steering at low speeds is a real drawback to enjoying our cars. Just cuting one out of a bone yard and transplanting it to the cars is not just a cut here bolt there kind of setup. They require sensors that tell engine rpm and car speed. I can be corrected here by those that know more than I do.For now I plan to use the pulse signal from the Stewart Warner speedo. It has a magnetic sensor that reads the bolts on the front hub(8 per rev). This may need to be manipulated for the correct sensor count.
I have just finished installing a Corsa C in my DRB. I have recieved much help from several forum members, Mick, Renato, and Keith Stafford to name just a few. I chose the Corsa C(2000-2006), but there are several others that can be used depending how you choose your electronics. The Corsa B, Toyota Yaris abs and non abs, along with the Saturn Vue - from 2002 to 2007, Chevrolet Equinox - from 2005 to 2007, Saturn Ion - from 2003 to 2006. All of these can use a false signal to fool the ECU. These can be supplied by Rally Wiz. I beleive some of our electronic gurus here on the forum are working on their own versions of the controllers. I'll leave it up to them to fill in this area as I know and understand the electornics, just not the implementation. If you want the whole story on the pin outs look here:Corsa C Electric Power steering (EPAS) - blog - Seventh Heaven - Locost - Haynes Roadster
I chose the Corsa C, with an adjustable height column. It not only has an adjustabble height feature but a variable height for the entire column. This allows me to mount the box much higher in the cabin. It also makes it easier to take the dash out for repairs or changes, I can drop the front of the column and the dash slides right out. It also allows for the angle of the steering wheel to be set for comfort. The central body of the unit remains fixed and I don't have to struggle with taking it out and back in.
Here it is mounted with the dash in.


Here is the side view with the dash out. You can recognize the standard raise and lower mechanism with its lock arm(about 2"of travel)


The front view sans dash. Still have to add some bracing to prevent torque travel.


Here it is with the front column droped.


This view shows adequate foot room from the high mount of the central unit. The old straight mount rod it replaces hit the tops of my shoes. You can also make out the rear bracing and temporary bolts. It is tack welded for now and will be reinforced with the entire unit removed.
I am hoping some of the others will post thier choices and how they setup their controllers.

At present the heater feed is taken off the thermostat near the water pump and both the feed and return hoses are taken down the central tunnel, I want to remove these two hoses and tee-off to the heater from the rad hoses in the front bay, for both feed and return. I am getting some ally Y joints made (rather than tee joints) to keep the pressure up for the heater. Question, does anyone know what I should do with the heater hoses on the engine, see image. You can see:-

Thermostat top-middle.
Heater feed 16mm hose on the left.
Heater return on the right, which has a tee to the water reservoir.

Do I just loop the heater feed from the t/stat to the heater return and close off the connection (heater) on the water tank?

Thanks in advance. K

All three are not working and I have no power on the red wire at the appropriate connector. The passenger side lights are working properly. I don't have a proper wiring diagram but I've checked the fuses up front and find no problem. Any suggestions? Are these lights on separate fuses left and right? Any and all help/suggestions is welcome. ]]> tednphx http://www.gt40s.com/forum/gt40-tech-fueling-electrics-engine-cooling/40254-driving-lights-rear-running-lic-plate-light.html
