Anyone know if there's any coil pack upgrade availble for k24z7??
The stock coil packs are good for 500hp. Honda does a very good job with their OEM units actually.
I'm sure down the road there will be upgrades.

That all depends on you, what is serious hp? 50% gain over stock ?? 75% ?? 100%???

If ignition upgrade are useless & don't produce any horsepower, I doubt companies like MSD, NGK can stay in business for 40+ years

I never said they were useless and didn't produce power, I just said that the OEM units are actually pretty good. Did you read what I posted?? :rolleyes:

Re: lets talk ignition upgrades

[HR][/HR] There is an avantage to having a more powerfull ignition system. While its not nessisary it does make a difference. The thing is with a stock ignition, there will be a load point where you'll have to start gapping your plugs down to get them to fire. While this works, you also reduce the initial spark kernel, affect total flame propagation, basically looseing power and effeciency. Granted the loss of power isn't huge, BUT there is a pretty noticable difference in how the car runs and responds with say a M&W ignition with a .026 plug gap, VS stock coils at a .016 plug gap. On our race car with the AEM, we had stock coils and switched to the M&W ProDrag 4 setup with the Mercury Magnetics coils and picked up over 50HP running stock gap on a BKR9EIX plug at the same boost. The car sounded noticably different. We have since ditched the AEM for a Motec M880 so we never track tested the M&W vs the Stock coil setup.

old school way to know if you need colder plugs & upgrade ignition coils, you feel your exhaust with your hand, if it's wet, too much fuel are dump into your exhaust = your ignition is weak & it's not burning off your fuel.

How do you "feel your exhaust with your hand?" Does one place their hand at the end of the tailpipe? Skin burns?

lol, no, you put your hand behind the tip while the car is idle, you feel the actual exhaust that's coming out of your muffler

i used to do it after a mod (b18 civic) & smell my hand for any hint of gas to determined if it's running rich or lean, it's ghetto but we don't have hondata to analyze the car back then...
 
The stock packs on the K series are good for up to 800hp. There's no need for these on 99.9% of the cars out there.
And in my opinion if I was in that power range I would switch to something very well known that is guaranteed reliable like AEM. Sure the AEM ones aren't direct replacement but I would have piece of mind and that's all that matters to me. So I suppose what it comes down to is what your preference is.
