[quote name='RICE RACING' date='Oct 15 2002, 09:48 PM']I use two Crane Hi-6's and two LX92 CDI Crane coils, one for each leading spark plug on my 566bhp 13B Turbo, I run 11 heat range plugs with premix + metering pump + water injection, this is hard **** to fire !!! The Crane set up is first class !
I have been running it now for almost 6 months (daily driver) and the only down side is that it is very hard on the ground electrode and the center electrode, it wears the plugs out about 10 times as fast compared to stock of transistor type non CDI ignition.
But if you are after performance and want to be able to fire a "cold" plug with out having a cold misfire or not take the risk with running to hot a plug cause your ignition is not strong enough then CDI is the go.
I realy love my Crane set up, I highly recommend that you use one box or cahnnel per leading plug, do not divide the energy over two plugs or coils.

I use the bosch coils HEC715 for my trailing fired by BOSCH 008 ignitors, they work OK, cannot compare to CDI though.
True many things make power, but you sure as hell cannot get transistorised ignitions to idle all day long with 11 heat range plugs ! Also they are not tolerant of rich fuel mixtures, alot of the high HP drag guys run VERY lean for a turbo engine wich reduces the amount of energy required from the ignition system to fire the cocktale in the combustion chamber.
Very high pressure ratios and rich mixtures need a strong spark for maximum power.
CDI is the king, the only problem is all of the good ones cost quite a bit of cash : (

I have been looking onto ignitions for a while and here is what I have to say. Direct fire is what everyone should do, It makes more power. period.
I like the MSD boxes but they are build messy (take a look inside of one sometime)
I dislike Jacobs products (they work great untill they blow up, my buddy went through 4 (FOUR!!!) Jacobs boxes in 2 years, everything was hooked up correct, and he was using everything that jacobs told him to use, spark plugs, wires, etc.)
Crane and Mallory make good, well built boxes, even with rev limiters
I would prefer the MSD 6AL because of 1 certain feature. The plug in rev limiting chips. Although it is not as convinient as some of the other boxes out there, it is very flexable. MSD sells a 2 stage rev limiter that will plug into this slot, so you can set staging rpm and top end rpm. MSD also sells a RPM limiter dial that will allow you to set your rpm from the drivers seat. Just imagine, being able to make split second changes to your launch rpm and top end rpm from the drivers seat. I don't know of any other box that will do that.

Dave, keep it stock. I had the HKS and didn't notice anything. I've still got my ignition stock and runnin 10's :bigok: If you do get anything, get a MSD digital 6 for the leading. Keep trailing stock. Its not a concern. Demetrios ran 10.1 on leading only. (Trailing wasn't firing at all)

quick question
you guys r just adding cdi boxes to the ignition to make it better right
i just bought a 12a but it only has the distributor so i have no clue as to how the igntions connections are made i am guessing that there is a signal wire from the distributor that triggers the coils but i read that the is some igntion box or something stock
also couldnt i just use like 2 accel super stock coils for coils or is that a no no
also has anyone tried the 300+ series accel ignition system you get a good coil and the box for $210 i am new to this and i want to get it running
thanks
