Twin plug advice

[Bronco]

Is there an alternative to the andial signal splitter?

looking for a complete set up for a 3.2/3.4 conversion.
Crankfire systems seem too expensive which leaves me with the mechanical solution. I'm assuming that its a must to have some kind of splitter to ease the burden on the DME system.

Anybody done anything different or should I bite the bullet and buy the Andial one?

Regards
David

The "big 3" are:
1 - crank triggered systems, the 2 most common being XDI & Megasquirt II with EDIS
2 - a dual distributor system - usually modify a 964 distributor for triggering, and run run 2 CDI boxes & an some electronics to control advance (as the 964 has no mechanical advance)
3 - 12-plug distributor - modify an existing distributor or somehow source an original (and you thought crankfire was expensive). This setup also requires 2 CDI boxes (and associated HW) but doesn't require an advance controller as the distributor has mechanical advance.

None of these options are cheap...

Long horn has good advice, I would add that Richard Clewett has some nice stuff available using Electromotive bits (I think this is the XDI he referred to) that is not too expensive and works really well.
Best of luck,
Cole

Supertec has a great twin plug alternative.

Sorry Henry... I forgot you had that. I guess #3 should have included "buy a new 12-plug distributor"

And those are purdy

whats this kinda thing cost?

+1 for the Supertec twin-plug distributor.

That 3.5 twin-plug MFI engine is in my garage

As they say, if you have to ask...

There are so many ways to build a high performance engine. Case in point, the "Wild" engine is a 2.8 short stoke built on a new old stock RSR case. Finding that case is like looking for a unicorn.
You also have many different options for case, rods and induction.
The short stroke 2.8 is a great engine especially for a long hood platform So building them offers great rewards.
Just to give you some idea about price, a base using a 3.0 turbo or Carrera case would cost around $15 K. Add to that $3 k for twin plugging, $6K for modified production MFI and you start seeing a trend.
If you want Ty rods add $2.5K. Ty valve $1.2 K. Built using our new slide valve system add $12-$18K depending on the pump.
If you want one built using a 3.0-3.6 case you will need a Supertec SuperCrank and that will add another $3k or so.
Please understand these are just general prices. If you are serious about building one of these gems we will be happy to negotiate something that fits your budget.
That said: if your budget is $10K we will help you secure proper medication.

Henry,

Have you considered adding a boss for and electronic (bosch type) injector to your slide valve offerings? Then folks could use them with a modern ECU....

Cheers

We built three slides. One was built for MFI and the other two can be used for MFI or EFI. We will convert the system to suit the buyer. The magic to our system is that the manifold base bolts on and can easily be modified. We can even make a 3 bolt base for a 3.6 head. Add a generic fuel rail and it's done.
We can change the port size to suit the application as well.
We also have stacks designed for use with an air filter housing for the daily driver.

Nice!!!!

I am wondering how much more power one can expect with slides vs standard ITB's with a throttle plated...

Cool.

Cheers

Cool pics and bits.

If you are intent on keeping your DME then I believe the Andial or similar box is your easiest choice.

Adapting an EDIS system to fire from your DME might actually be the cheapest.

If you make the leap away from the DME then you have even more options like Henry's or JB Racing's twin-plug distributor. They are both designed to perform both the triggering/timing side as well as the spark distribution function. You may be able to retain the DME's triggering of the spark but the distributor's firing. I'm not sure about that. If you go the twin-plug distributor route you need a pair of coils and a pair of MSD 6 boxes also (add ~$400) plus fabricating/adapting mounting panels.

I dont know what an andial box goes for. Henry can quote you a price for his distributor, JB's cost me around $1250. The parts to do it from EDIS would be about $150.

To expand alittle.
I wanted to keep the DME at this point.
I have sourced a 964 dizzy, was thinking about the Andial splitter so what else do I need to make it all work?

The cost for one of my distributors is right around $2,200.
You only need one MSD but you will need two coils.
We mount the single MSD box under the drivers seat to keep away from the RF signal generated by the plug wire and it also keeps it clean & dry.
We mount the coils on the relay board, removing it from the fan housing to isolate it from engine vibration.
The other benefit is a clean engine bay.
