I plan on making one, its my next project, I researched for a while and found the heat pads (tok a while), emailed back and forth with company to make sure they are pliable enough to wrap a head and will work correctly. Hopefully making it in a few weeks when i have a little more free time.

Thanx Mark, i placed that link up top

I am using these, they are sold as a largescale differential heater and do fit the head very nice.

It is made of simple resistance wire between 2 sheets aluminium foil sewed with some fabric. It runs on 12v and drains 2 amps.

Sounds interesting

COMP HEAT does everything I will ever need in regards to heating my engines, One of the best products I have ever bought.

Before that I used to use the old portable blow torch with a stubby holder cut down and covering the head leaving the top open and then just blow torch down the centre onto the plug, button and inner head which worked fine as well.

Now days just plug and play so to speak.

Yeah, for $80 plus bux, thats great, if i can make the same thing for less then $40 its a extra gallon of fuel or set of tires for my ride. Plus I like to Make it myself, just a fun project. The heat pad Im getting is 12volt & will plug right into my power supply, or starter box jack.. Plug and play as you say..

It's not the money thing. The Comp. Heat products are awesome. I use a friends now and it works perfect. Plus it's the original version. The thunder innovations is on $64 bucks. Personally if I was to buy one I like the one they sell over seas. I forget the name but it's metal and uses a light bulb and fan and regulates the heat. I just think its interesting what people come up with in their garage. I'm sure we can work a few hours over time and pay for a heater in less time then it takes to make one. But that's no fun!:p

You mean RC Surestart :)

They are the shizzle :sweat:

Really easy to use, quick to heat, and much cheaper than a comp heat.

But also to large and I am wondering how fragile the lightbulb is. Also with how it works I think a simple 10 bucks hairdryer will do the same.

Yes a sure start. I still think it's much better then heat gun because it has a thermostat and you can place it on your car without it falling over and do you something else.

They work really well. Much faster heater than the other but they costs MUCH more.

Can't get the same amount of heat in to the crankcase without melting plastics.

Lightbulb is fragile if u wack it with a screwdriver, but thats extremely hard to do! The bulb is in the metal casing, so it should be fine for a few knocks and drops.

Plus for me the best thing, if the bulb breaks (not that I have ever heard of one doing so).....so what! Go down to 99p store and get another one. Job done.

I was also thinking that if I bought a heater I like that the sure start heater might slide down the head and inside the body alittle easier. Does anyone sell the Sure Start heaters in the US?

where did you get that. very nice indeed

A fellow clubmember is making tire heaters for 1/5 cars and also these diff heaters. He normally sells them for 35 euro but for me they are cheaper. He is busy to create a better heater wrapping the whole head and using a stronger wire. The ones he is selling now do reach about 55 degrees celcius on 12v @2A. Not that high as we want it but it works very well!
It takes about 10 to 15 minutes to get it close to 50 degrees celcius. I put it on and let it warm up the engine and keep it on, it will stay at 55 degrees celcius. I always have a 12 amps powersupply with me for my chargers so no problem to leave it on.

Where they are sold:
