They are devices that fit on your spark plugs that boost your spark. They are available for RX7's with an adapter that allows you to use 5/8" hex sparkplugs. Looks like they will boost both HP and gas milage.

for that much money could you not get a MSD? That would give you hotter spark and a rev limiter.

Just my $02

 

Man that thing looks pretty damn cool. I may have to look into this some more.
REPEAT. Does anyone have exp with these?
Pros / Cons.
Hook us up

 

you think and MSd with give that much file.....
Take a long look at the site and what they are saying.
TRUST ME i dont know much about spark. But from what I have seen Looks like that Direct Hit would SMOKE a MSD box anyday.

 

would a really powerful ignition system make it easier to detonate?

 

Det as in N2O Det.....
or Blew my motor Det...
you know either way I would say no...
Then again I hardly ever right

 

yea ive read that it helps prevent it, but to me, a big *** spark would seem to be more prone to popping the A/F mix, rather than a slow burn, right?

 

Sounds interesting.

 

A guy that works there, Lou Camilli, responds to e-mail questions. Just hoping I can find someone who has tried them.

Looks like a scam to me. They never mention anything about how they work... just that they do. When that is the case, the product is often of the infomercial quality.

-Look, with duralube the bearing is fine!

 

i have always heard that a colder spark is better. if so then this would be the opposite effect unless you run high octane.

Someone is just gonna have to buy em....
How about everyone give me 10 bucks. Ill buy em and if they are good ill let you know. (I keep the directhits BTW) LOL. Had to try
But in all honesty someone will have to buy them that we know before we know the facts. Who wants to buy em..........?

 

this wasn't on an RX7 but interesting anyway.

That review seemed honest enuff to me... Still would like it more if someone here tried um...
Paging guinee pig with 154$ to blow.......

 

The Direct Hits is the same as the Nology Hot wires, except the capacitors are separate, not built into the wire.

Keep in mind that there's a BIG difference in rotary and boinger ignition. The spark duration in a rotary is a fraction of the boinger, therefore there's much less to improve upon.

If you're NA, iginition is the very LAST thing you want to spend money on. The stock ignition very easily supports 300rwhp. If you're Turbo, you're better off with an MSD or Jacobs.

As for capacitor type stuff, read this:
http://www.magnecor.com/magnecor1/truth.htm scroll to down the part starting with "CAPACITOR EFFECT WIRES". Granted you have to take into consideration the source, but it's a perspective to consider.
