get more power out of stock coils

[armandovivoni]

ok I was thinking for us modified dsm's. I still have stock coils. they are really good. but what if we made a 16 volt supply to the coils instead of 14 volts(when car is on) this would make the coils produce more power. would it?

 

[Thomas91169]

i dont know, why dont you look at the mod lists of the fastest dsmers. they arent using anything more than a coil on plug setup. no msd, no insane ignition coils. dsmlink maybe for a studderbox but thats it.

the stock ignition system is perfectly suited for 95% of the applications. the other 5% wouldnt be asking this question.

check out the tuning path(^^^in that top part of the browser) and youll see the right direction you should go.

I doubt it'll do anything. The coil is not going to produce more "power." Think about it this way. Is the spark going into your combustion chamber going to be any "stronger?" Hint: The answer is NO. The spark is still going to ignite the compressed fuel and air. I don't even see how you'd manage to get 16 volts dc going to the coil pack anyway. Raise voltage with an amplifier maybe?

I'm curious as to how you would change it to 16 volts. If you've got the know how to do that, you should have the know how to realize it would be pointless.

 

[rob_rousseau]

this MIGHT do something for ya, but you would be running the risk of smoking stuff. I think your time and money could be better spent elsewhere.

 

[Superbeast406]

Yeah, don't waste your time and money. The coil increases the voltage to the spark plugs, in effect it also reduces the amperage. You still get the same amount of wattage in the other end of the circuit, the only reason the voltage needs to be so high is so that the current can make it down the plug wire, and jump the gap on the plug, creating a spark. As long as you have spark at the proper time, your ignition system is doing its job. If you increase the voltage by 2 volts, in effect you are increasing the voltage at the plug by about 4k-5k volts (not sure what stock coils put out exactly). When you're already up at 40k volts 44k isn't gonna help enough to be worth it. The only mod thats worth anything in our cars is coil on plug- gets rid of wires, decreasing emi, while at the same time ensuring spark intensity at the plug.

ok, thanks for the input. so those coil on plugs, were can I get them from? do they connect the same way the stock coils connect?

are they a higher voltage coil?


are they better than MSD or bosch individual high current coils?

 

[armandovivoni]

hey, is there any way I can erase those replys that have nothing to do with the topic of my thread

 

[Thomas91169]

no, only mods have that power.

one of the vendors were selling a COP setup a while ago, though i think it was a special kinda thing, as the setups are kinda hard to come by.

A nice set of plugs and wires will yeild better results than you fabbing up a COP setup.


The plans were on here, but they were taken down. I can't remember if it was because a vendor was selling the kit or if the kit was really a waste of time and money. I want to say it was a little of both.

Here are two. One is the originator and has sold them since the dawn of DSM time. The other is fairly new but still makes good products.

You are now hearbye decreed captain high compression pistons.

Unless you are running rocket fuel or something that requires a really big spark to burn.. The factory coil's are more then enough for what our cars need, people have laid down 700+ HP on the coil pack with no problems from them. If you are worried about spark power then get a good set of plug wires and plugs(gap them to 0.025-0.030).

The CoP setup is imo a waste for these cars as the factory coil packs are already a very good set. If anything the CoP setup is an astetic mod for us more then a power mod.

 

[armandovivoni]

so then the msd dis-2,msd idividual high current and bosch coils. dont do anything unless I make 700+hp?

It's more that you will not notice ANY difference unless you are really pushing the stock system. The difference at high HP levels is noticable and therefore worth the cost at that point.

Thanks.

It really is just that simple though.

That's stretching it a bit. I can remember a time before Buschur.

Let me put it another way. 95% of the people here will notice no improvement what-so-ever. Of that 5% those that did notice a difference had a dying coil, bad plug or wire. The rest actualy needed it.
