MSD 6AL mount?
Can someone tell me how the MSD is mounted under the dash? A picture would be great.
Thanks, John

I mounted mine above the passenger footbox on the inside of the firewall.
No pics handy but if you look behind the dash there is quite a bit of open space on the inside of the firewall above the footbox.

I attached mine to the firewall above the passenger footbox using some click bonds, the rubber isolators, and a 1/16" thick plate of aluminum.

Like Jason I used click bonds for the MSD and various other attachments to the firewall. The beauty of using them is that there are NO holes, bolts, or evidence in the engine compartment.
Best of luck

If I mount an MSD I would like to have it out of sight. Don't know why exactly, since I'm sure it will create some other problems. I may just go with a petronix and be done with it.

Hello all,
I have never heard of Click Bonds. What are they.
Thanks,
MDN

There's plenty of room on the firewall above the footbox to mount the MSD box without seeing it once the dash is installed.
Click Bonds are an aircraft grade system that allows you to bond studs, standoffs, cable tie mounts to a surface without having to drill any holes. They work great and I got mine at the Flight Shop.

If you don't know why,then you can't possibly be sure.MSD is superior to anything with the Pertronix name on it.
The coil can also be hidden under the dash.Just don't use the bulkhead connectors.

I used rubber grommets to eliminate vibration -

I have a pretty extensive discussion of this here on the first page of our assembly manual. We use holes and the rubber grommets MSD supplies.
I would be very, very leary of a stick bond type fastener. The glue (no matter what it is) will soften as the firewall can become extremely hot. I don't think it would last long.

David,
What if they use some kind of epoxy resin system. You also could use some kind of press in studs so you do not see any bolt or screw heads. Some can be found at http://www.pemnet.com. You should be able to find a distruibuter near you.

I just put mine in the same place as David does per his build manual thread with exception on the end with all the dials I tilted it slightly to faciltitate fooling around with the settings. In the future- I also used the digital.

Not to disagree with David's reasoning; however, I have run the car on track days, including the Kirkham day, where the temps get pretty hot and have not experienced a problem. As a point of reference, I built a sub-panel that holds some extra gauges and part of the mount is click bond. The interesting thing about the sub-panel is that I had the part ceramic coated where it is baked and it held up without issue. There was discussion before baking my fasteners with the shop and we said give it a try and see what happens -- the result is great and the shop wanted to know where to buy them.
The mounting location is easy and access for the rev limiter is superb.
Best of luck
Scott

I mounted mine on the firewall with the click bond system. I misaligned one of the posts and had to replace it. I literally had to grind it off. There is no way these things will come loose because of engine compartment heat.

Scott,
You are always welcome to disagree with me. Nothing like experience to shoot down theory. I didn't know you had used the epoxy system in your car. Looks like epoxies must have gotten better (or I did a lousy job on the install the last time I did it)! Thanks for the links! I am ALWAYS interested in cooler ways of doing things.

David,
Gary McGill brought the product to my attention and he used them for many years on Marine applications. Click Bonds are used by Boeing and others in the avionics space too.
While I agree with your reasoning, it was this experience that led me to give it a try and like others it passed the test.
Having said that, there are places where this would not be a reasonable choice as a fastener.
Hope to see ya at the Kirkham Track Day.
Scott

We use the click bonds on all of our rockets and missiles we build here at the rocket-ranch. Oftern we have to attach something to a composite wound motor dome (no drilling!). They hold destruct charges, safe and arm switches, and other flight termination components, instrumentation brackets, battery mounts, etc... If done properly, they have no issues up to 160 degF. They might be capable of higher temps, but most of our stuff is maintained below 160. FWIW

This is sounding more and more like operator error--mine.
