Searched, minimal information turned up

Going to be heading north of 20 Psi soon and want to make sure my ignition system is up to par. (Probibly going for 25Psi)

I’m running a Haltech E6K wired right to the igniter, Stock FD coils, Taylor Spiro pros, 10.5’s all around.

No ignition break up or problems @ 18Psi but figured now was better than ever time to upgrade.

More powerful coils? How much can the stock one hold up to. Properly tuned of course ;-)

 

as for ignition i've seen the FD igniter with an MSD 6a on the leading support over 20 with FC coils.. i've seen the same setup with MSD coils run over 40.

 

ran 25 psi for a couple weeks. stock fc ignition w/ 10.5 magnecore wires. t04e 60 trim .96 a/r on pump gas.

 

i would say as a reliability mod get a the hks twin ign or an msd box at least for the main coil

 

First: run (4) Crane boxes and (4) Crane coils
turn off the multi spark option by setting the dials to 0,1

Second: Run colder race plugs minimum 10's


works wonders!

 

Which HI-6? Which coil?
:-)

 

I am running a Crane Hi-6 and LX92 coil per leading plug and stock FC trailing ignition.

It really can fire through anything. You can run ridiculously rich and still make lots of power.

It will eat plugs quickly ~ 4,000 miles and my iridiums were nearly halfway through the ground strap (change plugs with oil). I will try it with the stock style semi-surface discharge plugs to see if they last longer.

 

OR, I have no break-up running my E6K with 3-MSD6A(1 lead/2 trail), stock coils, and the Haltech for the igniter. I use Magnecore 10mm race wires, and 6725-11.5 plugs. I regularly see 20-25 psi, and I am running 10.5:1 after~7000 rpm, mid 11s elsewhere on 111 octane. My dynos are as smooth as glass with no smoothing on both a dynojet, and a dynapack. Carl

 

it's my understanding that the Hi-6 and the Hi-6S are for cars with distributor, and the Hi-6DI2 is for distributorless ignitions.

 

I have used this setup as well and can vouch for it.

 

So remove the stock igniter connections and use the Msd boxes as the igniter? Like connect the White wire from the Msd box to the ignition out (L) and dig out(T) From the haltech?

Wow that easy?

 

I have a nice jacobs box that i ran in my car that i will sell... im selling it bc im doing a completely diff. engine all together so....

... why are you posting here? I hope youre joking about the jacobs box

 

No.

"HI-6" = single-channel CDI
"HI-6S" = single-channel, inductive - NOT CDI
"HI-6DI2" = two-channel CDI

Crane Cams HI-6 CDI ( get two of them)
good for 3bar boost

 

Thank you, that's what I needed to know The descriptions on the websites I found the crane products on were kind of confusing.

 

This setup felt like the car was a electric motor it was sooo smooth.

 

Yeah, Crane Cams like to be really vague about their ignition boxes.
Too bad, they make decent stuff.

So hook the Hi-6 up like a points system, Now Do I wire the white wire from the Hi-6 to the haltech or from the wire coming from the igniter (bypass stock igniter? Or wire after igniter?) I would think that the Hi-6 would become the igniter but in the Hi-6 manual it says to hook the white wire up to the wire that went to the stock coil (after ignitor)

Thanks guys

 

For the E6K and HI-6 combo on a TII as I did you keep the stock ignitor and use the ignitor output as the HI-6 input.

Since the ignitor looked dopey with the coil removed off the top I put a nice black heatsink w/ thermal compound on the top of it. I later did read that ignitor can get really hot so maybe heat is more than rice?

 

Its for a FD but the ignition system setup should be the same for fd/fc
THANKS!

 

Haha, yes. This is crane cams for yah

My car was sooo smooth it was awsome and also the MoTeC helped.. too bad i sold the setup

 

crane p#'s 6000-6400(HI-6) and 730-0892(LX-92 coil) right ones?

 

Ill be Quiet after this one gets answered, i promise
