After a dissapointing weekend on the dyno (My fault). We had 3 cars running E85 and all had ignition problems.

1.Chris had HKS Twin Power, stock 9 plugs and ngk wires. (Had breakup at 15psi)

2.Tony had ls1 ignition, ls1 wires w/ stock 9 plugs, B10EGV and the high dollar 10.5plugs. (Had breakup at 21 psi)

3.Mine had magnecore wires, B10EGV plugs, TII coils and a 6AL on the leading. (Had breakup at 28 psi)

I later switched to stock 9's and it seam to help a bit. We were getting alot of noise from the interference B10EGV plugs and they don't like cold starts at all.

So, what ignition seems to work?

I am running the FC1000 on a stock T2 coil with 9's. I am up to 20psi and have no problems at all.

I am running ls7 coils, msd wires, and B10EGV's at 25 psi. I did have some cold start problems. Maybe I'll try 9's when I get my rotating assembly back from balancing and engine together.

I would have gone for more boost but ran out of turbo.

There's a thread i made in this section... a friend ran b9egv plugs, 25psi. 670hp. Melted the plugs on the 2nd run at the track.

No cdi. Bosch hec714 coils i think, with the x4 igniter box, lt10s computer and had no ignition break ups at all on e85 surprisingly. Cheap bosch spark leads too.

The car was perfect on the dyno. no ignition break ups at all. When it ran at the track it kept popping and fart all of 4th gear, it only had 4 indy blue injectors and was running very lean.

I have a TEC3 ECU with the TEC ignition with no issues so far.

Enzo runs the Autronic on his brothers car and a CDI system I think with no issues.

I run NGK 11.5's and also ran the 10.5's, no problems with these either.

There's something weird going on with you guys, I doubt it being E85 being hard to fire. Did you guys all get gas from the same station?

Look into the TEC ignition, you might like it. Ken Scheepers still runs a TEC unit and a few others out there.

Hmm, weird. 4 guys got tuned on E85 and we all got it from different locations, some from different states. Tec sounds high dolla....

I'm looking into the electromotive ignition systems.
Thanks again Anthony.

I didnt have any breakup as far as i remember.

ChrisRX8PR

I have two Stock LS2 coils for trailing and two MSD LS2 Coils for leading.....no ignition box, just running off the Microtech. I switched to this after suffering spark blowout with LS2 Coils leading and trailing when approaching the 500whp mark.

Its a Renesis but it shouldn't matter but its generally the same engine, same displacement, even more compression (which doesn't help the blow out situation) and running on the same fuel.

i dont know if this helps,, but here in Austin tx, some of the guys runnin E85, have had ignition probs. also. but in Supra 2JZ s. works ok on C16, but had to upgrade igniton when on E85.

dont know whats going on there!

Whenever you add more fuel to an engine you will need stronger spark to burn it...

E85 needs roughly 40% more fuel then gas. So it's pretty clear that you will need more spark..

Methanol needs more then double the amount of gas so spark is even more important..

I prefer Autronic and M&W CDI's. There's nothing else out there that compares..

MSD DIS-2, Digital 6's, Etc will also work just fine...

Does the autronic's 500r still have that problem of firing all the coils when initially turned on? i.e. key to the on position
It may not be a "problem" for everyone, but it would just be really annoying for me.

Also, are people still using the mercury marine coils in conjunction with the 500r?


Thanks

The 40% number was also something we wondered about, everyone had said 30% but once on the dyno, it was more like 40%

Someone else keeps telling me M&W as well, $2000

I see alot of high hp methanol guys running multiple 6AL's, would this work?

Thanks for all you help.

Not sure if you'd be interested in an M&W for half that price but if you are drop me a PM.

I'd love to, but I just cannot swing that right now. When is this Obama Stimulus coming? I need my ignition stimulated

You're just not in enough debt to qualify for the Obama cash. Get real stupid and lose a couple billion and he'll beat down your door trying to give it to you.

What do you guys think of a 6AL on the leading and a Dis-2 on the trailing? I'm seeing that alot of people prefer the stock TII coils over blaster coils. Crispeed talks about people running 50+psi of boost w/ the 6AL combo and methanol.

As you can see, I'm trying to do this on a somewhat budget.

I was on E85 by that Sunday morning too. I had stock TII coils with 4 - BUR9EQ's. Steve said I was starting to break up in the high RPM's at about 18psi. He said if I switched to 4 - BR10EIX's and got an MSD 6AL for the leading, I could have turned up the boost and got in the 400hp club. He didn't seem to think too highly of those B10EGV's either.

killahrx7

i'm using a msd 6a on leading with stock trailing plugs. no problems at 21 psi.

It's simple it's your ignition that's the problem. I dynoed 530rwhp last year with CDI on E85. Used a Autronic 500R CDI box and Crane Cams LS92 coils and had no breakup at all.

I used to have ignition problems on gas before when not running this setup. After switching to the Autronic CDI box and LS92 coils i have had no problems with ignition.

E85 is abit harder to ignite and because of the 30% more fuel, the plugs have a tendancy to foul out if the ignition is not strong enough. And will make the engine break up, because of too much fuel.

So switch to a good CDI system that supports rotary and you should be good.

Are all the cars getting tuned by the same person ? I would start there. Ive never had a single cold start issue or ignition breakup. I have run b10egv's up to 700hp with no breaking up issues. I start my car after sitting for a month with 11.5 plugs, 11's, 10egv's and it starts right up every time no matter what plug is in there, if its dead cold it takes about 3 secs longer thats it. It does take some time to warm up and rev crisp but it starts right up first time.

I've been using the Autronic 500R CDI box with MSD coils for a few years now and never had any issues.

Bro, I'd love to go with the 500R ignition. But, I just can't swing $1,000 for one.

I hate to be "that guy" but is there a cheaper setup out there that can give me what I need?

Would (3) 6AL's do the trick?
