First of all F4 tape is an orange colored tape that we use on the aircraft engines I work on, it is heat resistant.


which brings me to the point of this thread, I figured why not wrap all the wire harnesses on my FD in this tape , since the 13b creates so much heat, the tape would protect the harnesses from chaffing getting burnt up ect...


Good idea?

PS if you are interested in a roll of the tape send me a PM and I will see what I can do for you.

 

Any pics of it? Sounds neat. Do you know the heat range?

yea lemme get a shot of the tape, havent done it yet just contimplating on it.


The EGT on the aircraft engine reaches temps near the 300 degree mark, and the core itself even higher.

and the tape still holds its own.

 

But what happens when you need to get to the connectors, would it be a big orange sticky mess .

 

the tape doesn't melt.

and you don't have to wrap the connectors themselves, just the wire, BUT if you did wrap the connectors then you would just cut the tape off with a knife.

 

Orange in my engine compartment ....... no thanks

 

wrap it with the tape and put some black loom over it. . .

It also comes in black, the black is not "as" heat resistant as the orange but im sure it could do the job just fine

 

even without black loom orange would bring flare to a lot of engine compartments anyway. A lot of people have blue pipes and stuff. If the aftermarket had a orange turbo with a lot of performance gain people wouldnt care about the color just the performance gain. If enough of Rex users use it, it would be an Rx-7 trademark heh. Yah never know till u try. Then the average ricers would have orange tape in their engine compartments all over the place . They will look at ur car and be like "whoa an Rx-7....got the orange tape"

 

Count me in the "interested" column, especially if it comes in black. Looking forward to pics. Any addtional specs on this stuff...tolerances, antipated age and of course, cost?

 

It won't leave a residue. It work best if you wrap half of it over itself. I didn't think of this before but good one. while my engine is apart I'm going to do this. I have this tape all over the place at work. I think I even have blue.

 

im interested!

 

whats f4?

 

I can get the tape for free at work, of course if someone wants some there will be a price for it shipped, probably 10 or something.


as for the tapes limits, we use it here on aircraft engines, and they produce much more heat then a rotary does, so im sure it would work out just fine.

 

Nick13b do you use "peanut butter" tape at all. Its basically a rubber like replacement for electrical tape, but only adhere's to itself, which is in my opinion what makes the tape so cool. There is not adhesive at all on it. I use it on some of the electrical repairs I do on the aircraft that I work on in the army.

Also are we perhaps talking about the same tape? The stuff I use is black with a thin blue line on the top that is hardly noticable and is thicker in the middle than on the edges.

 

Yea I believe so because the tape I am speaking of only adheres to itself, we call it F4 tape, you must call it peanut butter

 

Im interested.

 

let me know how much shipping is to 07083. i would pick it up since its in jersey but i cant drive for a month =/

 

Since there's quite alot of interest in this it might save you some hassle if you can find out who manufactures this stuff and, if it's available, who sells it?

 

send me some and ill put some on my modified engine harness, and take pics of it installed, you'd be able to see it pretty good seeing as i have barely anything in my engine compartment

 

I assume you must have meant the coolant temp or dropped a zero from " near the 300 degree mark"?

Interesting idea for the tape actually. I'll have to find some quick. I need it for my Motec harness running into the firewall above the turbo's.

I hate to brin this up but no one seemed to have asked.
The tape it self stands up to heat well, but what is it's thermal insulation property? It really serves no purpose if it doesn't insulate well. The biggest problem the wiring harness faces is the thermal damage to the plastic (becomes brittle and flakey) and accelerated oxidation to the metal. If the tape doesn't insulate very well, there is no difference between cooking in 250 deg in the open vs. cooking in 250 deg inside a wrap.

 

Like I said this tape is used on jet engines, its insulates and protects the wire harness

 

adam c brings up a good point: If it doesn't look good, then it doesn't protect.

 

Hey we call the Stuff Strawberry tape......Because it smells just like Strawberrys.......By the way they also sell it at Autozone.....just in really really small rolls..... It really is a great insulator for wire and it is superwaterproof. I used it to wrap my connectors on my aircontrol valve that I am not using anymore.. (watertight)...I used the black on mine...but the orange one is out there to make it obvious that the connector is wrapped for quick location.

It apears to be made of a strechy rubber like subtance that is about 1 inch wide and 1/16 inch thick. It only sticks to itself ....but when it does stick to itself ,it is there forever. Cuts off 100% clean when U cut a slit in it with a knife.

I could possibly buy a case and sell them out if anyone is interested.
