Does that also imply that using a wasted spark ignition aka 2GDFIS would be bad with NOS? I wonder.

Yes anykind of secondary(trailing) spark would be a bad idea. Ideal setup would be some sort of CDI for leading wires only and making custom wires that "T" off the leading wires. Then plugging the "T"'d off wires into the trailing plugs. This woudl give you one strong spark leading spark on all 4 plugs.

Or I supose U could "T" the signal wire off the leading coil to the trailign coil and leave all the wires hooked up. That'd be easier...

Hmmmm maybe I should try that....

Thats a pain though I just unplug'm and use 1 good coil. (msd blaster)

We can debate this all day long buddy. Just because you don’t understand it doesn’t mean it’s wrong. Read a book and get back to me…

I just fire the leading. But I don't see why you couldn't fire both at the same time.

Your trailing plug ignites after your leading one. This will increase chances of detonation w/ nitrous or boost. I'm not saying people haven't done it. And if you use the proper fuels and timing you can get away with it. But it will hurt more than it will help.

the tach does not go around for the higher numbers on it
those numbers are for the voltmeter key on engine off
i believe is how its suposed to work
now they will go past 8k easily if you dont watch it

get online and see if you can find one of those 15k tachs for cheap might take a few months for a decent price

Just because you can rev a rotary that high doesn't mean you should. Unless you have extensive porting work done, you won' t make any power revving it that high. It just wears out the motor faster. And You have to use premix in the fuel if you're going to be reeving it to the moon and back. The OMP can't keep up with those RPMS.

look at any street or stock port engine dyno sheet. power curve falls around 6700
