how does these ignition systems produce horsepower out of n/a vehicles? like msd?? i notice a lot of honda guys have the msd ignition box under their hoods. I was looking around stuff, and noticed HKS has something called Twin Power Ignition Ampliflier that makes like 10 hp if installed. anybody know?? does it really work for n/a cars?
With forced induction, the extra force might blow out a weaker spark.
N/A, you don't need to spend your money on it.

Bwahaahah, getting power from ignition system upgrades is a BIG CROCK OF SHIT.
All an ignition system has to do is provide a spark good enough that ignites the mixture, thats all it has to do, when the combustion explosion takes place (where the power is created) the spark is already long gone. Same for the image of trying to get power from sparkplugs, its doesnt work, its a myth.
Now the reason to install better ignition systems is the fact that when you turbocharge or have high compression the mixture can get harder to ignite. However mostly people buy them to "be cool", "because its a new toy", "because magazines and marketing dictate they increase power" or several other reasons, such as distributorless ignition. Really I havent seen a stock system that isnt capable enough for a street tuned engine, be it force induction or n/a.
I myself run a Finnish made VPV-motorracing ignition controller, since I need to tune the timing curve of the car to suit the turbocharged nature of the car, even though, it still uses a standard Bosch coil and ignition controller, which can be bought almost anywhere, the box only controls the timing, launch control, shiftlight and revlimiter, power is still produced by the bosch coil.
The stock ignition coil produces around 40-50kV, which is more than you'll need.
there is a preformance aspect of it. BUt people don't understand throwing only one part of that ignition system in there is stupid. Even if it's not forced induction if you go and build a crazy engine a stock ignition system won't cut it sometimes. The stock one was designed for the stock engine....
Just because something is stock, doesnt mean its not designed for modified stuff. Like I said in my post, if you bothered to read it, if you have a very high compression or a turbocharged engine, you might need to upgrade the ignition box, because your stock system is gonna have a hard igniting the more compressed mixture. However, you wont need that in a street tuned engine. Just a heads up, MSD Blaster 2 coil produces 45,000V or 45kV, a no name brand coil for my nissan provides 41,000V or 41kV. The stock coil in a toyota provides ATLEAST 45kV and most likely in the 50kV range. Just because its made by MSD, etc, doesnt mean it will out perform the stock system.
P.S. Its annoying when someone repeats exactly what you say, just changing the wording.
yea but that doesn't just mean the coil. System would include the distrubuter, wires, plugs, and so on. So it would include it all. Doesn't matter if the coil is producing all that power if the wires and plugs don't use it all...

Well only way to go around that is to run Coil-on-plug setup which alot of modern cars run already. Quite frankly, 4A-FE isnt the newest technology around, still, the stock system like I said 2 times already, is ok for most street tuned vehicles. Sure wires are going to add some resistance, as is the distributor cap, but thats neglible. But the stock toyota system is quite efficient, because the coil is inside the distributor.
Oh and MSD 6AL uses a distributor based system, so benefit over the stock system is nil, plus you still wont get a power increase by changing to MSD. I'd spend the money on something else, that actually gives power.
well they have wires that are suposed to reduce the resistance, they are also usually larger than the stock ones with more insulation.
and yea for old technology though it's pretty decent. I'd still take it over the honda economy engines, yay sohc for honda :p. and vw did sohc for a long time.
From a money point of veiw the ignition in most cars of you era and above have a good ignition system which will work well with most minor mods..eg intake/exhaust/cams/porting/etc.....
in an application like above a new ignition system will give you very little gains if any for a hugh price!
as you start to go to huge comp ratio's (race fuel) or large boost apps (turbo/super charing) the mixture needs to be ignited under huge pressure and heat at the right time..
these types of motors cost so much money a lazy $1000.00 bucks for good ignition is needed and not a large finachile outlay in the sceam of things! eg if a motor is worth 10-20g then why not!
This next statment is in basic terms but as the boost of an engine climbs it has the potential to blow out the spark,like a misfire and increase engine/turbo temp uncontrolable
leading to the big bang!
this is only the case in extreme apps!
just make sure your system is in good working order..
