Guys I have been running this setup with shorty headers and keep drying out the silicone of my plug wires. Has anyone else ran into this? I know there are a few options of relocating the coils but I like the look of it. I already run woven boots but the heat from the headers dry the silicone out and then they crack. I was thinking of heat tape around the wires and then putting the boots back on. I also do not want to wrap the headers. I went through two sets of wires and I let the car sit for the last year because of it.Thanks guys for any advise..............

 

Are the AS&M's cera-metallic coated? With the blower, you've got to have very high under hood temperatures. Might want to find a way to vent the heat. I would also think that running a 3" Borla catback on a 383 running 12# of booost may be helping to increase under hood temperatures, due to the high backpressure. You need something like the Mufflex 4" catback if you don't want to do duals.

 

Thanks for the reply. They were coated some 12 years ago.........now just painted. I also run a 2.5" cowl hood to help with the heat loss. I was thinking of running some of that turbo/header wrap around my wires and then try to fit the heat boot over it. Just a thought, any more ideas? Thanks again

 

The Taylor woven fiberglass "Fire Sleeves" are excellent at protecting wires. I ran them many years ago with a set of JBA headers on my LT1, and the Electromotive 4-coil ignition setup (similar to the Delteq) sitting on top of the driver's valve cover. The wires were big, fat Taylor 409's (10.4mm), obviously "over the top" like your LTCC coils, and never had a problem with the wires.

And I suspect you have seen my alternative to mounting the LS1 coils above the engine. They stay much cooler this way:

 

Yes I did see this, I will have to spend some time and look it over. I don't have alot of room up front with intercooler pipes and 12 rib blower belt But thanks again...........

 

Injuneer, what do you think of using Dei header wrap (1500/2500degrees) to stuff inside my fiberglass sparkplug boots to help with heat? Or even a piece of aluminium foil in between them? Just doing some Brain storming. Thanks....

 

Aluminum foil will not serve as an insulator against conductive heat transfer. Aluminum conducts heat better than most metals. The only reason they put an aluminized coating on the outside of some high temp insulation is to serve as a reflective barrier to the emissive (radiant) heat transfer. Adding aluminum "foil" will do nothing, particularly inside the fire sleeves. It will probably reduce the effectiveness of the sleeves.

Have you tried the fire sleeves?

 

Yes, I have. They are still on the car. But where they are touching the headers the heat transfers over time and dries out the silicone. That is why I would like to put some higher temp wrap on the inside of the sleeves to possibly protect the plug wires. Or am I totaling missing the point here. The rating is for flash point not heat transfer protection huh? And I thought that was a good idea.............plmk
