spark "blow out" under boost?

[Ondonti]

I run a Ford 5.0 coil. should be 48000 volts.

I am probably going to end up running a Keene Bell Boost a Spark in the future because I want to stick with 1 coil.

OK, spark blowout at .022, .020 made a pass at 119mph. I need to upgrade the ignition. I'm running Comp conicals, so springs are not an issue. Does no one on this board other than Bakes run a non Mopar coil?

I'm running a Jacobs coil. Had an MSD also but disconnected it for trouble shooting purposes.

I'm running a Crane Hi-6 Ignition box on my Horizon. No spark blowout at 30+psi plus nitrous. It's an awesome ignition system. I have an extra complete kit with a coil if you are interested. PM me. It also has a built-in two-step.

I love HI 6. with my accel super coil. thing is tig welder

Here Dick is some good reading.

I got an MSD 6200 from a friend, hooked it up yesterday, car fired up. I opened the plug gap to .035, but I haven't tried it on the street yet. Maybe on friday I'll put a 1 day permit on it and play around.
How much was that Hi-6 anyways?

[boost geek]

Well, my friend came over and we took the car out for a few freeway on ramp beatings. My first pass I didn't have my alky turned on, hit 17.0 on the wideband in 4th gear. We did the run again with alky, ran 10.8 to 11.2, so alky works great, car was low on power at 17.0. (duh). Tha plugs are gapped at .035 with the MSD, and no misfires, so it works great. I can only get 28 psi boost spikes, my rev limiter is just too low at 7200 rpm. When I see the shift light flash at 7000, I already hit the rev limiter.Weather permiting, track next friday.

As usual, late to the party!...

But as to how "spark blow-out" feels. I can almost guarantee if you feel like you are hitting a rev-limiter, but you know you are not, it is in the ignition. The fix can be as cheap and easy as the aforementioned closing of the gap.

I recommend going at least .010" if possible to provide a noticeable difference. Sometimes it means new wires/cap & rotor, other times it means a new ignition box/coil...

In any case, the tighter gap will either make the problem go away, or not come on till a higher RPM, where the coil doesn't have as much "charge time" and essentially gets weaker, and so finds an easier place to go, instead of that mean nasty chamber with all that pressure!

Hope this was helpful to someone!

A side note on ignition, I tested many brands and styles of plugs on many cars over the years. The only plugs that surprised me with massive gains in power were the Pulstar plugs on our '91 R/T. Had to gap them at 0.028" for best results. I tried Halo, platinum (several brands), along with the typical varieties. I'm in Michigan getting some ignition systems tested at the Roush Performance Labs. One of the systems that might be of interest to guys running stupid boost levels is Aqua Pulser. You won't find a more potent spark on anything short of the space shuttle.

Never heard of them, but looks good.

Looks like a welder lol, better be a stout plug or it'll be gone in no time

[mpgmike]

As a matter of fact, the Aqua Pulser system is hard on plugs. Their race-only version can go through a set of plugs every pass down the 1320.....but oh my do you get down that strip quickly!

So far we tested our heavily modified 2008 Hyundai Sonata with stock plugs (41.74 mpg hyw, 26.97 city) and Pulstar plugs (41.99 hyw, 26.99 city). Later this week we will test the Aqua Pulser system. As a side note, the Sonata was certified new at 21 city and 30 hwy. The new hybrid Sonata is rated at 35 city and 40 hwy as a point of reference. I'll post the AP numbers probably early next week.

Ever test those E3 plugs Mike?

[mpgmike]

No, never tested the E3 plugs. They are conceptually similar to Halo plugs, but with more sharp edges. I've heard good things about them from people that kinda-sorta know how to test them (fill in the blanks between the lines here). I still like the Pulstars aside from the Roush test results.

I wouldn't trust any of those gimmicky plugs in any type of boosted application, especially one with higher boost.

[RoadWarrior222]

Well that's why I asked about the e3, looks robust. More so than a stock champion... and I've got an HC N/A motor eating plugs...

Really? Do I have to tell you again

Simons back!!!

Off to the dyno on the 15th.

My advice would be to figure out why its "eating" plugs. Champions work fine for most of us.
