Title: mounting new coil
Post by: bugnut68 on January 13, 2011, 23:26:28 pm
Okay, so I'm contemplating how to go about this, as I'm running a new Scat 36 hp non-heater shroud and will likely run Scat twist-style linkage to begin with... where to mount the coil?  I'm looking to keep the engine bay as clean as possible.  On one hand, I've heard you should keep the coil lead as short as possible, so if necessary I will drill holes in the shroud and mount it there.  I've seen other guys mount theirs on their firewall.  What is recommended?  It's my understanding that mounting the coil on the engine case  (not an option with the linkage I plan to use) will wear the coil out prematurely due to vibration.

I use a Jaycee coil mount on my firewall, look clean and is a very nice item! And less vibrations.

Up underneath by the tranny.  The coil is not THAT far away.  Just use a bit longer wire and its all tucked away out of sight.  Have had zero problems.  Works great and is totally unseen in the engine bay.  (thats the idea right?)  Here's mine.  Uh.... the flash made the metal look rusty, uh thats not right, uh my car is perfect......  NOT so much but I try!  Damn flash.

The bolt holes go right up into the tray behind the back seat.  I like it cuz it's sneaky and once in awhile someone will say... "where the F is your coil?"  I tell em' I dont use one.

Nice!  I like that idea.  Very stealthy! ;D

I know OEM applications where the coil wire is almost 24" long, and that's with 1000 ohm resister wire. If you don't have a radio, you can use solid core wire. Electricity travels at the speed of light, so what's a few more inches/cm :D.
As long as it is kept away from sharp edges, chaffing or near hot exhaust, you can put the coil where you want to. Just remember you will also need to modify the stock harness to supply the +12v, and extend the -1 dist wire too.
I do think it should be in an area that is not exposed to road spray and wet weather though, you don't want to promote corrosion or oxidation of the terminals.

that looks real clean, i have to agree as presently i have mine mounted on the firewall & it looks cluttered  >:( that will change soon though when i replace my 009 & blue coil & switch to my mag  8)

Now THAT is cool.  Please tell me what/how etc..  Thats some serious stuff there. 
You're running a "bolt" for a distributor.  Way better than a missing coil.... ha. 
How does that distributor-less ignition work and who makes it and I'm sure its very expensive.

You can see the crank sensor on the pulley -- -- I'm running batch fire so it fires at the top of each stroke -- you can see the coil packs at the upper part of the above picture, just mounted them....

Here is a full view when everything is there -- I've got it disassembled and doing final mock up right now -- hoses, wiring, coolers etc. and trying to get it all under the deck lid

With all the piping and hoses and wiring when it is done it'll never look as clean as yours Worm -- it is very nice -- Mine will look like a spagetti explosion at a pipe organ factory LOL -- but it will be a 400 Hp spagetti explosion lol

Oh it is an Electromotive EFI system and yes i sold my first born to buy it LOL -- -- Sorry for the hijack

No boots on the intake to hold the Throttle body from rotating LOL -- I probably should make a braket to hold it in place --

  It's my understanding that mounting the coil on the engine case  (not an option with the linkage I plan to use) will wear the coil out prematurely due to vibration.
When you get your engine components balanced, vibrations are almost non-existent.  I bet that myth was started by someone who cheaped out and didn't have his engine parts balanced. 
I don't see why the vibrations on the case would be anything different from the shroud, it's all connected solidly together.

I've had my coil mounted to the block for about 70k miles.  And it was well used when I started.
Here's the only pic I could find.  You can just see it on the other side of the alternator.

i like the clean look of ditching coil, hence my engine runs a mag  ;D
my mission, in turn, is to hide the breather box. which in general bothers me more when mounted in sight.

I can't even remember where I heard that rumor, Bruce, but it's good to see it's apparently bogus.  If I ever switch to hex-bar linkage that's the approach I'll likely take to mounting the coil.

Early KDF engines had the coil mounted on the backside of the fanshroud.

you can paint it the same color as the firewall, won't bother as much :)

Looks like Worm figured out how to add a pic to his signature! ^5!
