came across this from an email I recieved a few minutes ago. it has me intrigued.

http://www.compu-tronix.com/DIS8.htm

anyone have an thoughts on it? not entirely distributorless, but incorporates newer tech into a retro-fit design. yes, available for LA and B series mopars as well as hemi's.



Distributorless Ignition System for American V-8 Engines. Available for the following: Chevy SB or BB Standard or Tall Deck, Ford 289/302, Ford Windsor, Ford Cleveland, Ford FE, Chrysler SB 273/318/340/360, Chrysler 361/383/400 Chrysler 413/426/440 and Hemi, Pontiac 400 and AMC, Jeep. With D-W-E-L-L Control, Internal Tach Driver and Static Timing LED Light. The DIS4 (Distributorless Ignition System) is derived from new technology created by OEM’s to improve timing issues, energy loss, spark degradation and low emission standards associated with normal distributors. By isolating the electronics and incorporating them into our billet aluminum lid, we are able to retrofit technology from this century into your classic car. Improving timing consistency at all RPM’s, no loss in energy due to spark degradation, better fuel economy, easier start-up and more power!
The DIS4 is built rugged to handle any terrain… Water, dirt or sand cannot enter the DIS4. It’s a completely sealed unit!



Conventional cap and rotors allow for spark degradation, arching and ozone as the current travels through the rotor and across to the cap contacts. By doing away with these antique parts, the DIS8™ is capable of supplying a full energy charge from the coils to the spark plug with no spark loss. By designing a system that does not use a cap and rotor; we have essentially worked the antique out of your classic ignition system... and helped you into the 21st century!

Regardless of brand names, or claims to the contrary... The DIS system delivers more power than any single coil system, Bar None! Math and Physics can't be argued with. Simply put... It works!

Am I missing something. If the two leads plug into the coils, where does the system get its power from? Tach signal? Is there a separate control box of some sort?

exactly the thought I had. seems like not everything is shown or Im missing some integral aspect. I kind of like the thought of it, but would need to know a lot more before coughing up $600 on an ignition..even though you can do that easy enough with the more typical systems.

if anything, I love the way this thing looks. not sure Id mount the coils on my valve covers though.

msd hvc coil-$180
msd pro dist-$380
msd 7al-$520
msd pro wire-$100
=$1180
-$600
=$580 more then the dis
of coarse you can go the route i'd go and get the cheapest everything and maybe still be close to the $600.

I ran a similar system on a Volkswagen. They work great.

The good news is you now have four coils, thus the overall strain on the coils is reduced. So when the advertisement touts the superior nature of the multi coil setup they are being accurate. The bad news is the coils operate in wasted spark. Wasted spark means that the coils fire on both the compression and exhaust stroke. This isn't really a problem, (it actually reduces emissions slightly) the bad part is your throwing away 1/2 the spark so you are giving up 1/2 the advantage of having multiple coils. Again you are still getting a pretty big advantage with these setups. These modern coils will throw a flame that will knock you on your ass.

The thing really isn't "ditributor-less" you'll notice in the pic, a giant part that looks suspiciously like a distributor. As a result you are still using a mechanical part to determine the overall ignition timing of the motor. The other issue is, you'll notice the lack of a vacuum advance. For a race car this isn't a problem, but for a boulevard cruiser off idle response may suffer without vacuum advance. I an 800 lb. sandrail the lack of vacuum advance was not an issue.

Finally, do the even make a unit for big or small block mopars?

Regards,

Joe Dokes

yes. the LA and B/RB units are listed in the ad I received but not on the site itself, so likely a fairly new item. you'd probably have to call them to order one up.

I'll stick with my points type distributor. You can't beat it.

It is too bad they didn't notch the housing and take the harness out the side, rather than the top. That would have cleaned it up even more.
